TEMPLATE-FIXED PEPTIDOMIMETICS WITH ANTIMICROBIAL ACTIVITY

Abstract Template-fixed β-hairpin peptidomimetics of the general formula (I) wherein Z is a template-fixed chain of 12 α-amino acid residues which, depending on their positions in the chain (counted starting from the N-terminal amino acid) are Gly, or Pro, or of certain types which, as the remaining Symbols in the above formula, are defined in the description and the claims, and salts thereof, have the property to selectively inhibit the growth of or to kill microorganisms such as Pseudomonas aeruginosa. They can be used as disinfectants for foodstuffs, cosmetics, medicaments or other nutrient-containing materials, or as medicaments to treat or prevent infections. These β-hair-pin peptidomimetics can be manufactured by processes which are based on a mixed solid- and Solution phase synthetic strategy.
Full Text Template - fixed peptidomimetics
The present invention provides template-fixed β-hairpin peptidomimetics incorporating a
template-fixed chain of 12 α-amino acid residues which, depending on their positions in the
chain, are Gly or Pro, or of certain types, as defined herein below. These template-fixed β-
hairpin mimetics have a selective antimicrobial activity. In addition, the present invention
provides efficient synthetic processes by which these compounds can, if desired, be made in
parallel library-format. These β-hairpin peptidomimetics show improved efficacy,
bioavailability, half-life and most importantly a significantly enhanced ratio between
antibacterial activity on the one hand, and hemolysis of red blood cells on the other.
The growing problem of microbial resistance to established antibiotics has stimulated intense
interest in developing novel antimicrobial agents with new modes of action (H. Breithaupt,
Nat. Biotechnol 1999,17, 1165-1169). One emerging class of antibiotics is based on
naturally occurring cationic peptides (T. Ganz, R. I. Lehrer, Mol. Medicine Today 1999, 5,
292-297; R. M. Epand, H. J. Vogel, Biochim. Biophys. Acta 1999, 1462, 11-28). These
include disulfide-bridged β-hairpin and β-sheet peptides (such as the protegrins [V. N.. M.;
O. V. Shamova, H. A. Korneva, R. I. Lehrer, FEBSLett. 1993, 327, 231-236], tachyplesins
[T. Nakamura, II. Furunaka, T. Miyata, F. Tokunaga, T. Muta. S. Iwanaga, M. Niwa, T.
Takao, Y. Shimonishi, Y. J. Biol. Chem. 1988, 263, 16709-16713], and the defensins [R. I.
Lehrer, A. K. Lichtenstein, T. Ganz, Annu. Rev. Immunol. 1993, 11, 105-128], amphipathic
α-helical peptides (e.g. cecropins, dermaseptins, magainins, and mellitins [A. Tossi, L.
Sandri, A. Giangaspero, Biopolymers 2000, 55, 4-30]), as well as other linear and loop-
structured peptides. Although the mechanisms of action of antimicrobial cationic peptides are
not yet fully understood, their primary site of interaction is the microbial cell membrane (H.
W. Huang, Biochemistry 2000, 39, 8347-8352). Upon exposure to these agents, the cell
membrane undergoes permeabilization, which is followed by rapid cell death. However,
more complex mechanisms of action, for example, involving receptor-mediated signaling,
cannot presently be ruled out (M. Wu, E. Maier, R. Benz, R. E. Hancock, Biochemistry 1999,
38, 7235-7242).

The antimicrobial activities of many of these cationic peptides usually correlate with their
preferred secondary structures, observed either in aqueous solution or in membrane-like
environments (N. Sitaram, R. Nagaraj, Biochim. Biophys. Acta 1999, 1462, 29-54). Structural
studies by nuclear magnetic resonance (NMR) spectroscopy have shown that cationic
peptides such as protegrin 1 (A. Aumelas, M. Mangoni, C. Roumestand, L. Chiche, E.
Despaux, G. Grassy, B. Calas, A. Chavanieu, A. Eur. J. Biochem. 1996, 237, 575-583; R. L.
Fahrner, T. Dicckmann, S. S. L. Harwig, R. I. Lehrer, D. Eisenberg, J. Feigon, J. Client. Biol.
1996, 3, 543-550) and tachyplesin I (K. Kawano, T. Yoneya, T. Miyata, K. Yoshikawa.. F.
Tokunaga, Y. Terada, S. J. Iwanaga, S. J. Biol. Chem. 1990, 265, 15365-15367) adopt well
defined β-hairpin conformations, due to the constraining effect of two disulfide bridges. In
protegrin analogues lacking one or both of these disulfide bonds, the stability of the ß-hairpin
conformation is diminished, and the antimicrobial activity is reduced (J. Chen, T. J. Falla, H.
J. Liu, M. A. Hurst, C. A. Fujii, D. A. Mosca, J. R. Embree D. J. Loury, P. A. Radel, C. C.
Chang, L. Gu, J. C. Fiddes, Biopolymers 2000, 55, 88-98; S. L. Harwig, A. Waring, H. J.
Yang, Y. Cho, L. Tan, R. I. Lehrer, R. J. Eur. J. Biochem. 1996, 240, 352-357; M. E.
Mangoni, A. Aumelas, P. Charnet, C. Roumestand, L. Chiche, E. Despaux, G. Grassy, B.
Calas, A. Chavanieu, FEBS Lett. 1996, 383, 93-98; H. Tamamura, T. Murakami, S. Noriuchi,
K. Sugihara, A. Otaka, W. Takada, T. Ibuka, M. Waki, N. Tamamoto, N. Fujii, Chem.
Pharm. Bull. 1995, 43, 853-858). Similar observations have been made in analogues of
tachyplesin I (H. Tamamura, R. Ikoma, M. Niwa, S. Funakoshi, T. Murakami, N. Fujii,
Chem. Pharm. Bull. 1993, 41, 978-980) and in hairpin-loop mimetics of rabbit defensin NP-2
(S. Thennarasu, R. Nagaraj, Biochem. Biophys. Res. Comm. 1999. 254, 281-283). These
results show that the β-hairpin structure plays an important role in the antimicrobial activity
and stability of these protegrin-like peptides. In the case of the cationic peptides preferring a-
helical structures, the amphililic structure of the helix appears to play a key role in
determining antimicrobial activity (A. Tossi, L. Sandri, A. Giangaspero, A. Biopolymers
2000, 55,4-30). Gramicidin S is a backbone-cyclic peptide with a well defined β-hairpin
structure (S. E. Hull, R. Karlsson, P. Main, M. M. Woolfson, E. J. Dodson, Nature 1978, 275,
206-275) that displays potent antimicrobial activity against gram-positive and gram-negative
bacteria (L, H. Kondejewski, S. W. Fanner, D. S. Wishart, R. E. Hancock, R. S. Hodges, Int.
J. Peptide Prot. Res. 1996, 47, 460-466). The high hemolytic activity of gramicidin S has,
however, hindered its widespread use as an antibiotic. Recent structural studies by NMR have

indicated that the high hemolytic activity apparently correlates with the highly amphipathic
nature of this cyclic β-hairpin-like molecule, but that it is possible to dissociate antimicrobial
and hemolytic activities by modulating the conformation and amphiphilicity (L. H.
Kondejewski, M. Jelokhani-Niaraki, S. W. Farmer, B. Lix, M. Kay, B. D. Sykes, R. E.
Hancock, R. S. Hodges, J. Biol. Chem. 1999, 274, 13181-13192; C. MclnnesL. H.
Kondejewski, R. S. Hodges, B. D. Sykes, J. Biol. Chem. 2000, 275, 14287-14294).
A new cyclic antimicrobial peptide RTD-1 was reported recently from primate leukocytes
(Y.-Q. Tang, J. Yuan, G. Ösapay, K. Ösapay, D. Tran, C. J. Miller, A. J. Oellette, M. E.
Selsted, Science 1999, 286, 498-502. This peptide contains three disulfide bridges, which act
to constrain the cyclic peptide backbone into a hairpin geometry. Cleavage of the three
disulfide bonds leads to a significant loss of antimicrobial activity. Analogues of protegrins
(J. P. Tarn, C. Wu, J.-L. Yang, Eur. J. Biochem. 2000, 267, 3289-3300) and tachyplesins (J.-
P. Tam, Y.-A. Lu, J.-L. Yang, Biochemistry 2000, 39, 7159-7169; N. Sitaram, R. Nagaraij,
Biochem. Biophys. Res. Comm. 2000, 267, 783-790) containing a cyclic peptide backbone, as
well as multiple disulfide bridges to enforce a amphiphilic hairpin structure, have also been
reported. In these cases, removal of all the cystine constraints does not always lead to a large
loss of antimicrobial activity, but does modulate the membranolytic selectivity (J. P. Tarn, C.
Wu, J.-L. Yang, Eur. J. Biochem. 2000, 267, 3289-3300).
A key issue in the design of new selective cationic antimicrobial peptides are bioavailability,
stability and reduced haemolytic activity. The naturally occurring protegrins and tachyplesins
exert a significant hemolytic activity agairst human red blood cells. This is also the case for
protegrin analogues such as IB367 (J. Chen, T. J. Falla, H. J. Liu, M. A. Hurst, C. A. Fujii, D.
A. Mosca, J. R. Embree, D. J. Loury, P. A. Radel, C. C. Chang, L. Gu, J. C. Fiddes,
Biopolymers 2000, 55, 88-98; C. Chang, L. Gu, J. Chen, US-Pat: 5,916,872,1999). This high
hemolytic activity essentially obviates its use in vivo, and represents a serious disadvantage
in clinical applications. Also, the antibiotic activity of analogues often decreases significantly
with increasing salt concentration, such that under in vivo conditions (ca. 100-150 mM NaC1)
the antimicrobial activity may be severely reduced.

Protegrin 1 exhibits potent and similar activity against gram-positive and gram-negative
bacteria as well as fungi in both low- and high-salt assays. This broad antimicrobial activity
combined with a rapid mode of action, and their ability to kill bacteria resistant to other
classes of antibiotics, make them attractive targets for development of clinically useful
antibiotics. The activity against gram-positive bacteria is typically higher than against gram-
negative bacteria. However, protegrin 1 also exhibits a high hemolytic activity against human
red blood cells, and hence a low selectivity towards microbial cells. Oriented CD experiments
(W. T. Heller, A. J. Waring, R. I. Lehrer, H. W. Huang, Biochemistry 1998, 37, 17331-
17338) indicate that protegrin 1 may exist in two different states as it interacts with
membranes, and these states are strongly influenced by lipid composition. Studies of cyclic
protegrin analogues (J.-P. Tam, C. Wu, J.-L. Yang, Eur. J. Biochem. 2000, 267, 3289-3300)
have revealed, that an increase in the conformational rigidity, resulting from backbone
cyclization and multiple disulfide bridges, may confer membranolytic selectivity that
dissociates antimicrobial activity from hemolytic activity, at least in the series of compounds
studied.
Protegrin 1 is an 18 residues linear peptide, with an amidated carboxyl terminus and two
disulfide bridges. Tachyplesin I contains 17 residues, also has an amidated carboxyl terminus
and contains two disulfide bridges. Recently described backbone-cyclic protegrin and
tachyplesin analogues typically contain 18 residues and up to three disulfide bridges (J. P.
Tarn, C. Wu, J.-L. Yang, Eur. J. Biochem. 2000,267, 3289-3300; J. P. Tarn, Y.-A. Lu, J.-L.
Yang, Biochemistry 2000, 39, 7159-7169; N. Sitaram, R. Nagaraij, Biochem. Biophys. Res.
Comm. 2000, 267., 783-790).
Cathelicidin , a 37-residue linear helical-type cationic peptide, and analogues are currently
under investigation as inhaled therapeutic agents for cystic fibrosis(CF) lung disease (L.
Saiman, S. Tabibi, T. D. Starner, P. San Gabriel, P. L. Winokur, H. P. Jia, P. B. McGray, Jr.,
B. F. Tack, Antimicrob. Agents and Chemother. 2001, 45, 2838-2844; R. E. W. Hancock, R.
Lehrer, Trends Biotechnol. 1998,16, 82-88). Over 80% of CF patients become chronically
infected with pseudomonas aeruginosa (C. A. Demko, P. J. Biard, P. B. Davies, J. Clin.
Epidemiol. 1995, 48, 1041-1049; E. M. Kerem, R. Gold, H. Levinson, J. Pediatr. 1990, 116,
714-719). Other antimicrobial peptides against Pseudomonads (Y.H. Yau, B. Ho, N.S. Tan,
M.L. Ng, J.L. Ding, Antimicrob. Agents and Chemother. 2001, 45, 2820-2825 and herein

cited references), like FALL-39, SMAP-29, and lepidopteran cecropin display a few of the
desired attributes like potent antimicrobial activity over a wide range of pH, rapid killing rate,
and low hemolytic activity.
In the compounds described below, a new strategy is introduced to stabilize P-hairpin
conformations in backbone-cyclic cationic peptide mimetics exhibiting selective
antimicrobial activity. This involves transplanting the cationic and hydrophobic hairpin
sequence onto a template, whose function is to restrain the peptide loop backbone into a
hairpin geometry.
Template-bound hairpin mimetic peptidcs have been described in the literature (D, Obrecht,
M. Altorfer, J. A. Robinson, Adv. Med. Chem. 1999, 4, 1-68; J. A. Robinson, Syn. Lett. 2000,
4, 429-441) and the ability to generate β-hairpin peptidomimetics using combinatorial and
parallel synthesis methods has now been established (L. Jiang, K. Moehle, B. Dhanapal, D.
Obrecht, J. A. Robinson, Helv. Chim. Acta. 2000, 83, 3097-3112). Antibacterial template -
fixed peptidomimetics and methods for their synthesis have been described in International
Patent applications W002/070547 Al and W02004/018503 Al but these molecules do not
exhibit high plasma stability selectivity and particularly high potency.
The methods described herein allow the synthesis and screening of large hairpin mimetic
libraries, which in turn considerably facilitates structure-activity studies, and hence the
discovery of new molecules with potent selective antimicrobial and very low hemolytic
activity to human red blood cells. The present strategy allows to synthesize P-hairpin
peptidomimetics with novel selectivities towards various multi-drug resistant pseudomonas-
strains.
The β-hairpin peptidomimetics of the present invention are compounds of the general

The peptidomimetics of the present invention can also be enantiomers of the compounds of
formula I. These enantiomers can be prepared by a modification of the above processes in
which enantiomers of all chiral starting materials are used.
As used in this description, the term "alkyl", taken alone or in combinations, designates
saturated, straight-chain or branched hydrocarbon radicals having up to 24, preferably up to
12, carbon atoms, ioptionally substituted with halogen. Similarly, the term "alkenyl"
designates straight chain or branched hydrocarbon radicals having up to 24, preferably up to
12, carbon atoms and containing at least one or, depending on the chain length, up to four
olefinic double bonds, optionally substituted with halogen. The term "lower" designates
radicals and compounds having up to 6 carbon atoms. Thus, for example, the term "lower
alkyl" designates saturated, straight-chain or branched hydrocarbon radicals having up to 6
carbon atoms, such as methyl, ethyl, n-propyl, isopropyl, n-butyl, sec-butyl, isobutyl, tert.-
butyl and the like. The term "aryl" designates aromatic carbocyclic hydrocarbon radicals
containing one or two six-membered rings, such as phenyl or naphthyl, which may be
substituted by up to three substituents such as Br, C1, F, CF3, NO2, lower alkyl or lower

alkenyl. The term "heteroaryl" designates aromatic heterocyclic radicals containing one or
two five- and/or six-membered rings, at least one of them containing up to three heteroatoms
selected from the group consisting of O, S and N and said ring(s) being optionally
substituted; representative examples of such optionally substituted heteroaryl radicals are
indicated hereinabove in connection with the definition of R77.
The structural element -A-CO- designates amino acid building blocks which in combination
with the structural element -B-CO- form templates (a1) and (a2). Templates (a) through (p)
constitute building blocks which have an N-terminus and a C-terminus oriented in space in
such a way that the distance between those two groups may lie between 4.0-5.5A. A peptide
chain Z is linked to the C-terminus and the N-terminus of the templates (a) through (p) via
the corresponding N- and C-termini so that the template and the chain form a cyclic structure
such as that depicted in formula I. In a case as here where the distance between the N- and C-
termini of the template lies between 4.0-5.5A the template will induce the H-bond network
necessary for the formation of a P-hairpin conformation in the peptide chain Z. Thus template
and peptide chain form a β-hairpin mimetic.
The P-hairpin conformation is highly relevant for the anti-bacterial activity of the P-hairpin
mimetics of the present invention. The p-hairpin stabilizing conformational properties of the
templates (a) through (p) play a key role not only for the selective antibacterial activity but
also for the synthetic processes defined hereinabove, as incorporation of the templates at the
beginning or near the middle of the linear protected peptide precursors enhances cyclization
yields significantly.
Building blocks A1-A69 belong to a class of amino acids wherein the N-terminus is a
secondary amine forming part of a ring. Among the genetically encoded amino acids only
proline falls into this class. The configuration of building block Al through A69 is (D), and
they are combined with a building block -B-CO- of (L)-configuration. Preferred
combinations for templates (al) are-DAl-CO-LB-CO-to DA69-CO-LB-CO-. Thus, for
example, DPro-LPro constitutes the prototype of templates (al). Less preferred, but possible
are combinations-LA1-CO-DB-CO- to LA69-CO-DB-CO- forming templates (a2). Thus, for
example, LPro-DPro constitutes the prototype of template (a2).

It will be appreciated that building blocks -A1-C0- to -A69-CO- in which A has (D)-
configuration, are carrying a group R1 at the α-position to the N-terminus. The preferred
values for R1 are H and lower alkyl with the most preferred values for R1 being H and
methyl. It will be recognized by those skilled in the art, that A1-A69 are shown in (D)-
configuration which, for R1 being H and methyl, corresponds to the (R)-configuration.
Depending on the priority of other values for R1 according to the Cahn, Ingold and Prelog-
rules, this configuration may also have to be expressed as (S).
In addition to R1 building blocks -A1-C0- to -A69-CO- can carry an additional substituent
designated as R2 to R17. This additional substituent can be H, and if it is other than H, it is
preferably a small to medium-sized aliphatic or aromatic group. Examples of preferred
values for R2 to R17 are:
-R2: H; lower alkyl; lower alkenyl; (CH2)mOR55 (where R55: lower alkyl; or lower
alkenyl); (CH2)mSR56 (where R56: lower alkyl; or lower alkenyl); (CH2)mNR33R34 (where R33:

Among the building blocks A1 to A69 the following are preferred: A5 with R2 being H, A8,
A22, A25, A38 with R2 being H, A42, A47, and A50. Most preferred are building blocks of
type A8':


wherein R20 is H or lower alkyl; and R64 is alkyl; alkenyl; aryl; aryl-lower alkyl; or
heteroaryl-lower alkyl; especially those wherein R64 is n-hexyl (A8'-l); n-heptyl (A8'-2); 4-
(phenyl)benzyl (A8'-3); diphenylmethyl (A8'-4); 3-amino-propyl (A8'-5); 5-amino-pentyl
(A8'-6); methyl (A8'-7); ethyl (A8'-8); isopropyl (A8'-9); isobutyl (A8'-10); n-propyl (A81-
11); cyclohexyl (A8'-12); cyclohexylmethyl (A8'-13); n-butyl (A8'-14); phenyl (A8'-15);
benzyl (A8'-16); (3-indolyl)methyl (A8'-17); 2-(3-indolyl)ethyl (A8'-18); (4-phenyl)phenyl
(A8'-19); and n-nonyl (A8'-20).
Building block A70 belongs to the class of open-chain a-substituted α-amino acids, building
blocks A71 and A72 to the corresponding p-amino acid analogues and building blocks A73-
A104 to the cyclic analogues of A70. Such amino acid derivatives have been shown to
constrain small peptides in well defined reverse turn or U-shaped conformations (C. M.
Venkatachalam, Biopolymers, 1968, 6, 1425-1434; W. Kabsch, C Sander, Biopolymers 1983,
22, 2577). Such building blocks or templates are ideally suited for the stabilization of β-
hairpin conformations in peptide loops (D. Obrecht, M. Altorfer, J. A. Robinson, "Novel
Peptide Mimetic Building Blocks and Strategies for Efficient Lead Finding", Adv. Med
Chem. 1999, Vol.4, 1-68; P. Balaram, "Non-standard amino acids in peptide design and
protein engineering", Curr. Opin. Struct. Biol. 1992,2, 845-851; M. Crisma, G. Valle, C.
Toniolo, S. Prasad, R. B. Rao, P. Balaram, "p-turn conformations in crystal structures of
model peptides containing α,α- disubstituted amino acids", Biopolymers 1995, 35, 1-9; V. J.
Hruby, F. Al-Obeidi, W. Kazmierski, Biochem. J. 1990, 268, 249-262).
It has been shown that both enantiomers of building blocks -A70-CO- to A104-CO- in
combination with a building block -B-CO- of L-configuration can efficiently stabilize and
induce β-hairpin conformations (D. Obrecht, M. Altorfer, J. A. Robinson, "Novel Peptide
Mimetic Building Blocks and Strategies for Efficient Lead Finding", Adv. Med Chem. 1999,
Vo1.4, 1-68; D. Obrecht, C. Spiegler, P. Schönholzer, K. Müller, H. Heimgartner, F. Stierli,

Helv. Chim. Acta 1992, 75, 1666-1696; D. Obrecht, U. Bohdal, J. Daly, C. Lehmann, P.
Schönholzer, K. Müller, Tetrahedron 1995,51, 10883-10900; D. Obrecht, C. Lehmann, C.
Ruffieux, P. SchSnholzer, K. Mailer, Helv. Chim. Acta 1995, 78,1567-1587; D. Obrecht, U.
Bohdal, C. Broger, D. Bur, C. Lehmann, R. Ruffieux, P. Schfinholzer, C. Spiegler, Helv.
Chim. Acta 1995, 78, 563-580; D. Obrecht, H. Karajiannis, C. Lehmann, P. Schonholzer, C.
Spiegler, Helv. Chim. Acta 1995, 78,703-714).
Thus, for the purposes of the present invention templates (al) can also consist of-A70-CO-
to A104-CO- where building block A70 to A104 is of either (D)- or (L)-configuration, in

The peptidic chain Z of the P-hairpin mimetics described herein is generally defined in terms
of amino acid residues belonging to one of the following groups:
Group C -NR20CH(R72)CO-; "hydrophobic: small to medium-sized"
Group D -NR20CH(R73)CO-; "hydrophobic: large aromatic or
heteroaromatic"
Group E -NR20CH(R74)CO-; "polar-cationic" and "urea-derived"
Group F -NR20CH(R84)CO-; "polar-non-charged or anionic"
Group H -NR20-CH(CO-)-(CH2)4-7-CH(CO-)-NR20-;
-NR20-CH(CO-)(CH2)pSS(CH2)p-CH(CO-)-NR20-;
-NR20-CH(CO-)-(-(CH2)pNR20CO(CH2)p-CH(CO-)-NR20-;and
-NR20-CH(CO-)-(-(CH2)pNR20CONR20(CH2)p-CH(CO-)-NR20-;
"interstrand linkage"

Furthermore, the amino acid residues in chain Z can also be of formula -A-CO- or of formula
-B-CO- wherein A and B are as defined above. Finally, Gly can also be an amino acid residue
in chain Z, and Pro can be an amino acid residue in chain Z, too, with the exception of
positions where interstrand linkages (H) are possible.
Group C comprises amino acid residues with small to medium-sized hydrophobic side chain
groups according to the general definition for substituent R72. A hydrophobic residue refers to
an amino acid side chain that is uncharged at physiological pH and that is repelled by
aqueous solution. Furthermore these side chains generally do not contain hydrogen bond
donor groups, such as (but not limited to) primary and secondary amides, primary and
secondary amines and the corresponding protonated salts thereof, thiols, alcohols,
phosphonates, phosphates, ureas or thioureas. However, they may contain hydrogen bond
acceptor groups such as ethers, thioethers, esters, tertiary amides, alkyl- or aryl phosphonates
and phosphates or tertiary amines. Genetically encoded small-to-medium-sized amino acids
include alanine, isoleucine, leucine, methionine and valine.
Group D comprises amino acid residues with aromatic and heteroaromatic side chain groups
according to the general definition for substituent R73. An aromatic amino acid residue refers
to a hydrophobic amino acid having a side chain containing at least one ring having a
conjugated π-electron system (aromatic group). In addition they may contain hydrogen bond
donor groups such as (but not limited to) primary and secondary amides, primary and
secondary amines and the corresponding protonated salts thereof, thiols, alcohols,
phosphonates, phosphates, ureas or thioureas, and hydrogen bond acceptor groups such as
(but not limited to) ethers, thioethers, esters, tetriary amides, alkyl- or aryl phosphonates -and
phosphates or tertiary amines. Genetically encoded aromatic amino acids include
phenylalanine and tyrosine.
A heteroaromatic amino acid residue refers to a hydrophobic amino acid having a side chain
containing at least one ring having a conjugated π-system incorporating at least one
heteroatom such as (but not limited to) O, S and N according to the general definition for
substituent R77. In addition such residues may contain hydrogen bond donor groups such as
(but not limited to) primary and secondary amides, primary and secondary amines and the

corresponding protonated salts thereof, tfaiols, alcohols, phosphonates, phosphates, ureas or
thioureas, and hydrogen bond acceptor groups such as (but not limited to) ethers, thioethers,
esters, tetriary amides, alkyl- or aryl phosphonates -and phosphates or tertiary amines.
Genetically encoded heteroaromatic atnino acids include tryptophan and histidine.
Group E comprises amino acids containing side chains with polar-cationic, acylamino- and
urea-derived residues according to the general definition for substituen R74. Polar-cationic
refers to a basic side chain which is protonated at physiological pH. Genetically encoded
polar-cationic amino acids include arginine, lysine and histidine. Citrulline is an example for
an urea derived amino acid residue.
Group F comprises amino acids containing side chains with polar-non-charged or anionic
residues according to the general definition for substituent R84. A polar-non-charged or
anionic residue refers to a hydrophilic side chain that is uncharged and, respectively anionic
at physiological pH (carboxylic acids being included), but that is not repelled by aqueous
solutions. Such side chains typically contain hydrogen bond donor groups such as (but not
limited to) primary and secondary amides, carboxyclic acids and esters, primary and
secondary amines, thiols, alcohols, phosphonates, phosphates, ureas or thioureas. These
groups can form hydrogen bond networks with water molecules. In addition they may also
contain hydrogen bond acceptor groups such as (but not limited to) ethers, thioethers, esters,
tetriary amides, carboxylic acids and carboxylates, alkyl- or aryl phosphonates -and
phosphates or tertiary amines. Genetically encoded polar-non-charged amino acids include
asparagine, cysteine, glutamine, serine and threonine, but also aspartic acid and glutamic
acid.
Group H comprises side chains of preferably (L)-amino acids at opposite positions of the β-
strand region that can form an interstrand linkage. The most widely known linkage is the
disulfide bridge formed by cysteines and homo-cysteines positioned at opposite positions of
the β-strand. Various methods are known to form disulfide linkages including those described
by: J. P. Tarn et al. Synthesis 1979, 955-957; Stewart et al., Solid Phase Peptide Synthesis,
2d Ed., Pierce Chemical Company, III., 1984; Ahmed et al. J. Biol. Chem. 1975, 250, 8477-
8482; and Pennington et al., Peptides, pages 164-166, Giralt and Andreu, Eds., ESCOM

Leiden, The Netherlands, 1990. Most advantageously, for the scope of the present invention,
disulfide linkages can be prepared using acetamidomethyl (Acm)- protective groups for
cysteine. A well established interstrand linkage consists in linking ornithines and lysines,
respectively, with glutamic and aspartic acid residues located at opposite β-strand positions
by means of an amide bond formation. Preferred protective groups for the side chain amino-
groups of ornithine and lysine are allyloxycarbonyl (Alloc) and allylesters for aspartic and
glutamic acid. Finally, interstrand linkages can also be established by linking the amino
groups of lysine and ornithine located at opposite β-strand positions with reagents such as
N,N-carbonylimidazole to form cyclic ureas.
As mentioned earlier, positions for interstrand linkages are positions P4 and P 9 and/or P2
and P1 1 taken together. Such interstrand linkages are known to stabilize the β-hairpin
conformations and thus constitute an important structural element for the design of β-hairpin
mimetics.
Most preferred amino acid residues in chain Z are those derived from natural a-amino acids.

Examples 1, 2, 6, 16, 19,22, 24, 25, 28, 29, 32, 35, 40, 41,49, 50.
The processes of the invention can advantageously be carried out as parallel array syntheses
to yield libraries of template-fixed β-hairpin peptidomimetics of the above general formula I.
Such parallel syntheses allow one to obtain arrays of numerous (normally 24 to 192, typically
96) compounds of general formula I in high yields and defined purities, minimizing the
formation of dimeric and polymeric by-products. The proper choice of the functionalized
solid-support (i.e. solid support plus linker molecule), templates and site of cyclization play
thereby key roles.
The functionalized solid support is conveniently derived from polystyrene crosslinked with,
preferably 1-5%, divinylbenzene; polystyrene coated with polyethyleneglycol spacers
(TentagelR); and polyacrylamide resins (see also Obrecht, D.; Villalgordo, J.-M, "Solid-
Supported Combinatorial and Parallel Synthesis of Small-Molecular-Weight Compound
Libraries", Tetrahedron Organic Chemistry Series, Vol. 17, Pergamon, Elsevier Science,
1998).
The solid support is functionalized by means of a linker, i.e. a bifunctional spacer molecule
which contains on one end an anchoring group for attachment to the solid support and on the
other end a selectively cleavable functional group used for the subsequent chemical
transformations and cleavage procedures. For the purposes of the present invention two types
of linkers are used:

Type 1 linkers are designed to release the amide group under acidic conditions (Rink H,
Tetrahedron Lett. 1987,28, 3783-3790). Linkers of this kind form amides of the carboxyl
group of the amino acids; examples of resins functionalized by such linker structures include
4-[(((2,4-dimethoxyphenyl)Fmoc-aminomethyl)phenoxyacetamido) aminomethyl] PS resin,
4-[(((2,4-dimethoxyphenyl)Fmoc-aminomethyl)phenoxyacetamido)aminomethyl]-4-
methylbenzydrylamine PS resin (Rink amide MBHA PS Resin), and 4-[(((2,4-
dimethoxyphenyl)Fmoc-aminomethyl)phenoxyacetamido) aminomethyl] benzhydrylamine
PS-resin (Rink amide BHA PS resin). Preferably, the support is derived from polystyrene
crosslinked with, most preferably 1-5%, divinylbenzene and functionalized by means of the
4- (((2,4-dimethoxyphenyl)Fmoc-aminomethyl)phenoxyacetamido) linker.
Type 2 linkers are designed to eventually release the carboxyl group under acidic conditions.
Linkers of this kind form acid-labile esters with the carboxyl group of the amino acids,
usually acid-labile benzyl, benzhydryl and trityl esters; examples of such linker structures
include 2-methoxy-4-hydroxymethylphenoxy (SasrinR linker), 4-(2,4-dimethoxyphenyl-
hydroxymethyl)-phenoxy (Rink linker), 4-(4-hydroxymethyl-3-methoxyphenoxy)butyric acid
(HMPB linker), trityl and 2-chlorotrityl. Preferably, the support is derived from polystyrene
crosslinked with, most preferably 1-5%, divinylbenzene and functionalized by means of the
2-chlorotrityl linker.
When carried out as parallel array syntheses the processes of the invention can be
advantageously carried out as described herein below but it will be immediately apparent to
those skilled in the art how these procedures will have to be modified in case it is desired to
synthesize one single compound of the above formula I.
A number of reaction vessels (normally 24 to 192, typically 96), equal to the total number of
compounds to be synthesized by the parallel method, are loaded with 25 to 1000 mg,
preferably 100 mg, of the appropriate functionalized solid support, preferably 1 to 3% cross-
linked polystyrene or Tentagel resin.

The solvent to be used must be capable of swelling the resin and includes, but is not limited
to, dichloromethane (DCM), dimethylformamide (DMF), N-methylpyrrolidone (NMP),
dioxane, toluene, tetrahydrofuran (THF), ethanol (EtOH), trifluoroethanol (TFE),
isopropylalcohol and the like. Solvent mixtures containing as at least one component a polar
solvent (e. g. 20% TFE/DCM, 35% THF/NMP) are beneficial for ensuring high reactivity
and solvation of the resin-bound peptide chains (Fields, G. B., Fields, C. G., J. Am. Chem.
Soc. 1991,113,4202-4207).
With the development of various linkers that release the C-terminal carboxylic acid group
under mild acidic conditions, not affecting acid-labile groups protecting functional groups in
the side chain(s), considerable progresses have been made in the synthesis of protected
peptide fragments. The 2-methoxy-4-hydroxybenzylalcohol-derived linker (SasrinR linker,
Mergler et al., Tetrahedron Lett. 1988, 29 4005-4008) is cleavable with diluted trifluoroacetic
acid (0.5-1% TFA in DCM) and is stable to Fmoc deprotection conditions during the peptide
synthesis, Boc/tBu-based additional protecting groups being compatible with this protection
scheme. Other linkers which are suitable for the process of the invention include the super
acid labile 4-(2,4-dimethoxyphenyl-hydroxymethyl)-phenoxy linker (Rink linker, Rink, H.
Tetrahedron Lett. 1987,28, 3787-3790), where the removal of the peptide requires 10%
acetic acid in DCM or 0.2% trifluoroacetic acid in DCM; the 4-(4-hydroxymethyl-3-
methoxyphenoxy)butyric acid-derived linker (HMPB-linker, Flörsheimer & Riniker, Peptides
1991,1990 131) which is also cleaved with 1%TFA/DCM in order to yield a peptide fragment
containing all acid labile side- chain protective groups; and, in particular, the 2-
chlorotritylchloride linker (Barlos et al., Tetrahedron Lett. 1989, 30, 3943-3946), which
allows the peptide detachment using a mixture of glacial acetic acid/trifluoroethanol/DCM
(1:2:7) for 30 min.
Suitable protecting groups for amino acids and, respectively, for their residues are, for
example,
for the amino group (as is present e. g. also in the side-chain of lysine)
Cbz benzyloxycarbonyl
Boc tert-butyloxycarbonyl
Fmoc 9-fluorenylmethoxycarbonyl

Alloc allyloxycarbonyl
Teoc trimethylsilylethoxycarbonyl
Tcc trichloroethoxycarbonyl
Nps o-nitrophenylsulfonyl;
Trt triphenymethyl or trityl
for the carboxyl group (as is present e. g. also in the side-chain of aspartic
and glutamic acid) by conversion into esters with the alcohol components
tBu tert-butyl
Bn benzyl
Me methyl
Ph phenyl
Pac Phenacyl
Allyl
Tse trimethylsilylethyl
Tce trichloroethyl;
for the guanidino group (as is present e. g. in the side-chain of arginine)
Pmc 2,2,5,7,8-pentamethylchroman-6-sulfonyl
Ts tosyl (i. e. p-toluenesulfonyl)
Cbz benzyloxycarbonyl
Pbf pentamethyldihydrobenzofuran-5-sulfonyl
for the hydroxy group (as is present e. g. in the side-chain of threonine and
serine)
tBu tert.-butyl
Bn benzyl
Trt trityl
and for the mercapto group (as is present e. g. in the side-chain of cysteine)

Acm acetamidomethyl
tBu tert.-butyl
Bn benzyl
Trt trityl
Mtr 4-methoxytrityl..
The 9-fluorenylmethoxycarbonyl- (Fmoc)-protected amino acid derivatives are preferably
used as the building blocks for the construction of the template-fixed p-hairpin loop mimetics
of formula I. For the deprotection, i. e. cleaving off of the Fmoc group, 20% piperidine in
DMF or 2% DBU/2% piperidine in DMF can be used.
The quantity of the reactant, i. e. of the amino acid derivative, is usually 1 to 20 equivalents
based on the milliequivalents per gram (meq/g) loading of the functionalized solid support
(typically 0.1 to 2.85 meq/g for polystyrene resins) originally weighed into the reaction tube.
Additional equivalents of reactants can be used, if required, to drive the reaction to
completion in a reasonable time. The reaction tubes, in combination with the holder block
and the manifold, are reinserted into the reservoir block and the apparatus is fastened
together. Gas flow through the manifold is initiated to provide a controlled environment, for
example, nitrogen, argon, air and the like. The gas flow may also be heated or chilled prior to
flow through the manifold. Heating or cooling of the reaction wells is achieved by heating the
reaction block or cooling externally with isopropanol/dry ice and the like to bring about the
desired synthetic reactions. Agitation is achieved by shaking or magnetic stirring (within the
reaction tube). The preferred workstations (without, however, being limited thereto) are
Labsource's Combi-chem station and MultiSyn Tech's-Syro synthesizer.
Amide bond formation requires the activation of the α-carboxyl group for the acylation step.
When this activation is being carried out by means of the commonly used carbodiimides such
as dicyclohexylcarbodiimide (DCC, Sheehan & Hess, J. Am. Chem. Soc. 1955, 77, 1067-
1068) or diisopropylcarbodiimide (DIC, Sarantakis et al Biochem. Biophys. Res.
Commun.1976, 73, 336-342), the resulting dicyclohexylurea and diisopropylurea is insoluble
and, respectively, soluble in the solvents generally used. In a variation of the carbodiimide
method 1-hydroxybenzotriazole (HOBt, König & Geiger, Chem. Ber 1970,103,788-798) is

included as an additive to the coupling mixture. HOBt prevents dehydration, suppresses
racemization of the activated amino acids and acts as a catalyst to improve the sluggish
coupling reactions. Certain phosphonium reagents have been used as direct coupling
reagents, such as benzotriazol-l-yl-oxy-tris-(dimethylamino)-phosphonium
hexafluorophosphate (BOP, Castro et al., Tetrahedron Lett. 1975,14, 1219-1222; Synthesis,
1976,751-752), or benzotriazol-1-yl-oxy-tris-pyrrolidino-phosphonium hexaflurophoshate
(Py-BOP, Coste et al., Tetrahedron Lett. 1990,31,205-208), or 2-(lH-benzotriazol-l-yl-
)l,l,3,3-tetramethyluronium terafluoroborate (TBTU), or hexafluorophosphate (HBTU,
Knorr et al., Tetrahedron Lett. 1989,30,1927-1930), or 1-benzotriazol-l-
[bis(dimethylamino)methylene]-5-chloro-hexafluorophosphate-l,3-oxide(HCTU); these
phosphonium reagents are also suitable for in situ formation of HOBt esters with the
protected amino acid derivatives. More recently diphenoxyphosphoryl azide (DPPA) or O-(7-
aza-benzotriazol-l-yl)-N,N,N',N'-tetramethyluronium tetrafluoroborate (TATU) or O-(7-aza-
benzotriazol-l-yl)-N,N,N',N'-tetramethyluronium hexafluorophosphate (HATU)/7-aza-l-
hydroxy benzotriazole (HOAt, Carpino et al., Tetrahedron Lett. 1994, 35,2279-2281) have
also been used as coupling reagents.
Due to the fact that near-quantitative coupling reactions are essential, it is desirable to have
experimental evidence for completion of the reactions. The ninhydrin test (Kaiser et al., Anal.
Biochemistry 1970, 34, 595), where a positive colorimetric response to an aliquot of resin-
bound peptide indicates qualitatively the presence of the primary amine, can easily and
quickly be performed after each coupling step. Fmoc chemistry allows the
spectrophotometric detection of the Fmoc chromophore when it is released with the base
(Meienhofer et al., Int. J. Peptide Protein Res. 1979,13, 35-42).
The resin-bound intermediate within each reaction tube is washed free of excess of retained
reagents, of solvents, and of by-products by repetitive exposure to pure solvent(s) by one of
the two following methods:
1) The reaction wells are filled with solvent (preferably 5 ml), the reaction
tubes, in combination with the holder block and manifold, are immersed and agitated for 5 to
300 minutes, preferably 15 minutes, and drained by gravity followed by gas pressure applied
through the manifold inlet (while closing the outlet) to expel the solvent;

2) The manifold is removed from the holder block, aliquots of solvent
(preferably 5 ml) are dispensed through the top of the reaction tubes and drained by gravity
through a filter into a receiving vessel such as a test tube or vial.
Both of the above washing procedures are repeated up to about 50 times (preferably about 10
times), monitoring the efficiency of reagent, solvent and by-product removal by methods
such as TLC, GC, or inspection of the washings.
The above described procedure of reacting the resin-bound compound with reagents within
the reaction wells followed by removal of excess reagents, by-products and solvents is
repeated with each successive transformation until the final resin-bound fully protected linear
peptide has been obtained.
Before this fully protected linear peptide is detached from the solid support, it is possible, if
desired, to selectively deprotect one or several protected functional group(s) present in the
molecule and to appropriately substitute the reactive group(s) thus liberated. To this effect,
the functional group(s) in question must initially be protected by a protecting group which
can be selectively removed without affecting the remaining protecting groups present. Alloc
(allyloxycarbonyl) is an example for such an amino protecting group which can be selectively
removed, e.g. by means of Pd° and phenylsilane in CH2C12, without affecting the remaining
protecting groups, such as Fmoc, present in the molecule. The reactive group thus liberated
can then be treated with an agent suitable for introducing the desired substituent Thus, for
example, an amino group can be acylated by means of an acylating agent corresponding to
the acyl substituent to be introduced. For the formation of pegylated amino acids such as
IPegK, or SPegK, preferably a solution of 5 equivalents of HATU (N-[(dimethylamino)-lH-
l,2,3-triazolo[4,5-b]pyridin-l-ylmethyIene]-N-methylmethanaminiumhexafluorophosphate
N-oxide) in dry DMF and a solution of 10 equivalents of DIPEA (Diisopropyl ethaylamine)
in dry DMF and 5 equivalents of 2-[2-(2-methoxyethoxy)ethoxy] acetic acid (IPeg) and,
respectively, 2-(2-methoxyethoxy)acetic acid (sPeg), is applied to the liberated amino group
of the appropiate amino acid side chain for 3 h. The procedure is thereafter repeated for
another 3h with a fresh solution of reagents after filtering and washing the resin.

Before this fully protected linear peptide is detached from the solid support, it is also
possible, if desired, to form (an) interstrand linkage(s) between side-chains of appropriate
amino acid residues at opposite positions of the β-strand region.
Interstrand linkages and their formation have been discussed above, in connection with the
explanations made regarding groups of the type H which can, for example, be disulfide
bridges formed by cysteine and homocysteine residues at opposite positions of the β-strand;
or lactam bridges formed by glutamic and aspartic acid residues linking ornithine and,
respectively, lysine residues, or by glutamic acid residues linking 2,4-diaminobutyric acid
residues located at opposite β-strand positions by amide bond formation. The formation of
such interstrand linkages can be effected by methods well known in the art
For the formation of disulfide bridges preferably a solution of 10 equivalents of iodine
solution is applied in DMF or in a mixture of CH2C12 /MeOH for 1.5 h which is repeated for
another 3h with a fresh iodine solution after filtering of the iodine solution, or in a mixture of
DMSO and acetic acid solution, buffered with 5% with NaHCO3 to pH 5-6 for 4h, or in water
after having been adjusted to pH 8 with ammonium hydroxide solution by stirring for 24h or
ammonium acetate buffer adjusted to pH 8 in the presence of air, or in a solution of NMP and
tri-n- butylphosphine (preferably 50 eq.).
Detachment of the fully protected linear peptide from the solid support is achieved by
immersion of the reaction tubes, in combination with the holder block and manifold, in
reaction wells containing a solution of the cleavage reagent (preferably 3 to 5 ml). Gas flow,
temperature control, agitation and reaction monitoring are implemented as described above
and as desired to effect the detachment reaction. The reaction tubes, in combination with the
holder block and manifold, are disassembled from the reservoir block and raised above the
solution level but below the upper lip of the reaction wells, and gas pressure is applied
through the manifold inlet (while closing the outlet) to efficiently expel the final product
solution into the reservoir wells. The resin remaining in the reaction tubes is then washed 2 to
5 times as above with 3 to 5 ml of an appropriate solvent to extract (wash out) as much of the
detached product as possible. The product solutions thus obtained are combined, taking care
to avoid cross-mixing. The individual solutions/extracts are then manipulated as needed to

isolate the final compounds. Typical manipulations include, but are not limited to,
evaporation, concentration, liquid/liquid extraction, acidification, basification, neutralization
or additional reactions in solution.
The solutions containing fully protected linear peptide derivatives which have been cleaved
off from the solid support and neutralized with a base, are evaporated. Cyclization is then
effected in solution using solvents such as DCM, DMF, dioxane, THF and the like. Various
coupling reagents which were mentioned earlier can be used for the cyclization. The duration
of the cyclization is about 6-48 hours, preferably about 16 hours. The progress of the reaction
is followed, e. g. by RP-HPLC (Reverse Phase High Performance Liquid Chromatography).
Then the solvent is removed by evaporation, the fully protected cyclic peptide derivative is
dissolved in a solvent which is not miscible with water, such as DCM, and the solution is
extracted with water or a mixture of water-miscible solvents, in order to remove any excess
of the coupling reagent
Finally, the fully protected peptide derivative is treated with 95% TFA, 2.5% H2O, 2.5% TIS
or another combination of scavengers for effecting the cleavage of protecting groups. The
cleavage reaction time is commonly 30 minutes to 12 hours, preferably about 2.5 hours. The
volatiles are evaporated to dryness and the crude peptide is dissolved in 20% AcOH in
water and extracted with isopropyl ether or other solvents which are suitable therefor.
The aqueous layer is collected and evaporated to dryness, and the fully deprotected
cyclic peptide derivative of formula I is obtained as end-product. Depending on its purity,
this peptide derivative can be used directly for biological assays, or it has to be further
purified, for example by preparative HPLC.
Alternatively the detachment, cyclisation and complete deprotection of the fully protected
peptide from the solid support can be achieved manually in glass vessels.
As mentioned earlier, it is thereafter possible, if desired, to convert a fully deprotected
product of formula I thus obtained into a pharmaceutically acceptable salt or to convert a
pharmaceutically acceptable, or unacceptable, salt thus obtained into the corresponding free

compound of formula I or into a different, pharmaceutically acceptable, salt Any of these
operations can be carried out by methods well known in the art.
The template starting materials of formula II used in the processes of the invention, pre-
starting materials therefor, and the preparation of these starting and pre-starting materials are
described in International Application PCT/EP02/01711, published as WO 02/070547 Al.
The β-hairpin peptidomimetics of the invention can be used in a wide range of applications in
order to inhibit the growth of or to kill microorganisms. In particular they can be used to
selectively inhibit the growth of or to kill microorganisms such as Pseudomonas aeruginosa.
They can be used for example as disinfectants or as preservatives for materials such as
foodstuffs, cosmetics, medicaments and other nutrient-containing materials. The β-hairpin
peptidomimetics of the invention can also be used to treat or prevent diseases related to
microbial infection in plants and annuals.
For use as disinfectants or preservatives the β-hairpin peptidomimetics can be added to the
desired material singly, as mixtures of several β-hairpin peptidomimetics or in combination
with other antimicrobial agents. The β-hairpin peptidomimetics may be administered per se
or may be applied as an appropriate formulation together with carriers, diluents or excipients
well known in the art
When used to treat or prevent infections or diseases related to such infections, particularly
infections related to respiratory diseases such as cystic fibrosis, emphysema and asthma;
infections related to skin or soft tissue diseases such as surgical wounds, traumatic wounds
and burn wounds; infections related to gastrointestinal diseases such as epidemic diarrhea,
necrotizing enterocolitis and typhlitis; infections related to eye diseases such as keratitis and
endophthalmitis; infections related to ear diseases such as otitis, infections related to CNS

osteochondritis and osteomyelitis; infections related to cardiovascular diseases such as
endocartitis and pericarditis; or infections related to gastrourinal diseases such as

epididymitis, prostatitis and urethritis; the β-hairpin peptidomimetics can be administered
singly, as mixtures of several β-hairpin peptidomimetics, in combination with other
antimicrobial or antibiotic agents, or anti cancer agents, or antiviral (e. g. anti-HIV) agents, or
in combination with other pharmaceutically active agents. The β-hairpin peptidomimetics can
be administered per se or as pharmaceutical compositions.
Pharmaceutical compositions comprising β-hairpin peptidomimetics of the invention may be
manufactured by means of conventional mixing, dissolving, granulating, coated tablet-
making, levigating, emulsifying, encapsulating, entrapping or lyophilizing processes.
Pharmaceutical compositions may be formulated in conventional manner using one or more
physiologically acceptable carriers, diluents, excipients or auxiliaries which facilitate
processing of the active β-hairpin peptidomimetics into preparations which can be used
pharmaceutically. Proper formulation depends upon the method of administration chosen.
For topical administration the β-hairpin peptidomimetics of the invention may be formulated
as solutions, gels, ointments, creams, suspensions, etc. as are well-known in the art
Systemic formulations include those designed for administration by injection, e.g.
subcutaneous, intravenous, intramuscular, intrathecal or intraperitoneal injection, as well as
those designed for transdermal, transmucosal, oral or pulmonary administration.
For injections, the β-hairpin peptidomimetics of the invention may be formulated in adequate
solutions, preferably in physiologically compatible buffers such as Hink's solution, Ringer's
solution, or physiological saline buffer. The solution may contain formulatory agents such as
suspending, stabilizing and/or dispersing agents. Alternatively, the β-hairpin peptidomimetics
of the invention may be in powder form for combination with a suitable vehicle, e.g., sterile
pyrogen-free water, before use.
For transmucosal administration, penetrants appropriate to the barrier to be permeated are
used in the formulation as known in the art.

For oral administration, the compounds can be readily formulated by combining the active β-
hairpin peptidomimetics of the invention with pharmaceutically acceptable carriers well
known in the ait Such carriers enable the β-hairpin peptidomimetics of the invention to be
formulated as tablets, pills, dragees, capsules, liquids, gels, syrups, slurries, suspensions etc.,
for oral ingestion of a patient to be treated. For oral formulations such as, for example,
powders, capsules and tablets, suitable excipients include fillers such as sugars, such as
lactose, sucrose, mannitol and sorbitol; cellulose preparations such as maize starch, wheat
starch, rice starch, potato starch, gelatin, gum tragacanth, methyl cellulose,
hydroxypropylmethyl cellulose, sodium carboxymethylcellulose, and/or polyvinylpyrrolidone
(PVP); granulating agents; and binding agents. If desired, desintegrating agents may be
added, such as cross-linked polyvinylpyrrolidones, agar, or alginic acid or a salt thereof, such
as sodium alginate. If desired, solid dosage forms may be sugar-coated or enteric-coated
using standard techniques.
For oral liquid preparations such as, for example, suspensions, elixirs and solutions, suitable
carriers, excipients or diluents include water, glycols, oils, alcohols, etc. In addition, flavoring
agents, preservatives, coloring agents and the like may be added.
For buccal administration, the composition may take the form of tablets, lozenges, etc.
formulated as usual.
For administration by inhalation, the β-hairpin peptidomimetics of the invention are
conveniently delivered in form of an aeorosol spray from pressurized packs or a nebulizer,
with the use of a suitable propellant, e.g. dichlorodifluoromethane, trichlorofluromethane,
carbon dioxide or another suitable gas. In the case of a pressurized aerosol the dose unit may
be determined by providing a valve to deliver a metered amount Capsules and cartridges of
e.g. gelatin for use in an inhaler or insufflator may be formulated containing a powder mix of
the p-hairpin peptidomimetics of the invention and a suitable powder base such as lactose or
starch.

The compounds may also be formulated in rectal or vaginal compositions such as
suppositories together with appropriate suppository bases such as cocoa butter or other
glycerides.
In addition to the formulations described previously, the β-hairpin peptidomimetics of the
invention may also be formulated as depot preparations. Such long acting formulations may
be administered by implantation (e.g. subcutaneously or intramuscularly) or by intramuscular
injection. For the manufacture of such depot preparations the β-hairpin peptidomimetics of
the invention may be formulated with suitable polymeric or hydrophobic materials (e.g. as an
emulsion in an acceptable oil) or ion exchange resins, or as sparingly soluble salts.
In addition, other pharmaceutical delivery systems may be employed such as liposomes and
emulsions well known in the art. Certain organic solvents such as dimethylsulfoxide also may
be employed. Additionally, the β-hairpin peptidomimetics of the invention may be delivered
using a sustained-release system, such as semipermeable matrices of solid polymers
containing the therapeutic agent. Various sustained-release materials have been established
and are well known by those skilled in the art Sustained-release capsules may, depending on
their chemical nature, release the compounds for a few weeks up to over 100 days.
Depending on the chemical nature and the biological stability of the therapeutic agent,
additional strategies for protein stabilization may be employed.
As the β-hairpin pepdidomimetics of the invention may contain charged residues, they may
be included in any of the above-described formulations as such or as pharmaceutically
acceptable salts. Pharmaceutically acceptable salts tend to be more soluble in aqueous and
other protic solvents man are the corresponding free base forms.
The β-hairpin peptidomimetics of the invention, or compositions thereof, will generally be
used in an amount effective to achieve the intended purpose. It is to be understood that the
amount used will depend on a particular application.
For example, for use as a desinfectant or preservative, an antimicrobially effective amount of
a β-hairpin peptidomimetic of the invention, or a composition thereof, is applied or added to

the material to be desinfected or preserved. By antimicrobially effective amount is meant an
amount of a p-hairpin peptidomimetic of the invention, or a composition thereof, that inhibits
the growth of, or is lethal to, a target microbe population. While the antimicrobially effective
amount will depend on a particular application, for use as desinfectants or preservatives the
β-hairpin peptidomimetics of the invention, or compositions thereof, are usually added or
applied to the material to be desinfected or preserved in relatively low amounts. Typically,
the β-hairpin peptidomimetics of the invention comprise less than about 5% by weight of a
desinfectant solution or material to be preserved, preferably less than 1% by weight and more
preferably less than 0.1% by weight. An ordinary skilled expert will be able to determine
antimicrobially effective amounts of particular p-hairpin pepdidomimetics of the invention
for particular applications without undue experimentation using, for example, the in vitro
assays provided in the examples.
For use to treat or prevent microbial infections or diseases related to such infections, the β-
hairpin pepidomimetics of the invention, or compositions thereof, are administered or applied
in a therapeutically effective amount. By therapeutically effective amount is meant an amount
effective in ameliorating the symptoms of, or in ameliorating, treating or preventing
microbial infections or diseases related thereto. Determination of a therapeutically effective
amount is well within the capacities of those skilled in the art, especially in view of the
detailed disclosure provided herein.
As in the case of desinfectants and preservatives, for topical administration to treat or prevent
bacterial infections a therapeutically effective dose can be determined using, for example, the
in vitro assays provided in the examples. The treatment may be applied while the infection is
visible, or even when it is not visible. An ordinary skilled expert will be able to determine
therapeutically effective amounts to treat topical infections without undue experimentation.
For systemic administration, a therapeutically effective dose can be estimated initially from
in vitro assays. For example, a dose can be formulated in animal models to achieve a
circulating β-hairpin peptidomimetic concentration range that includes the IC50 as determined
in the cell culture (i.e. the concentration of a test compound that is lethal to 50% of a cell
culture), the MIC, as determined in cell culture (i.e. the concentration of a test compound that

is lethal to 100% of a cell culture). Such information can be used to more accurately
determine useful doses in humans.
Initial dosages can also be determined from in vivo data, e.g. animal models, using
techniques that are well known in the art One having ordinary skills in the art could readily
optimize administration to humans based on animal data.
Dosage amount for applications as antimicrobial agents may be adjusted individually to
provide plasma levels of the β-hairpin peptidomimetics of the invention which are sufficient
to maintain the therapeutic effect. Therapeutically effective serum levels may be achieved by
administering multiple doses each day.
In cases of local administration or selective uptake, the effective local concentration of the β-
hairpin peptidomimetics of the invention may not be related to plasma concentration. One
having the skills in the art will be able to optimize therapeutically effective local dosages
without undue experimentation.
The amount of β-hairpin peptidomimetics administered will, of course, be dependent on the
subject being treated, on the subject's weight, the severity of the affliction, the manner of
administration and the judgement of the prescribing physician.
The antimicrobial therapy may be repeated intermittently while infections are detectable or
even when they are not detectable. The therapy may be provided alone or in combination
with other drugs, such as for example antibiotics or other antimicrobial agents.
Normally, a therapeutically effective dose of the β-hairpin peptidomimetics described herein
will provide therapeutic benefit without causing substantial toxicity.
Hemolysis of red blood cells is often employed for assessment of toxicity of related
compounds such as protegrin or tachyplesin. Values are given as %-lysis of red blood cells
observed at a concentration of 100|xg/ml. Typical values determined for cationic peptides
such as protegrin and tachyplesin range between 30-40% with average MIC-values of 1-

5μg/ml over a wide range of pathogens. Normally, p-hairpin peptidomimetics of the
invention will show hemolysis in a range of 0.5-10%, often in a range of 1-5%, at activity
levels comparable to those mentioned above for protegrin and tachyplesin. Thus preferred
compounds exhibit low MIC-values and low %-hemolysis of red blood cells observed at a
concentration of 100μ.g/ml.
Toxicity of the β-hairpin peptidomimetics of the invention herein can be determined by
standard pharmaceutical procedures in cell cultures or experimental animals, e.g., by
determining the LD50 (the dose lethal to 50% of the population) or the LD100 (the dose lethal
to 100% of the population). The dose ratio between toxic and therapeutic effect is the
therapeutic index. Compounds which exhibit high therapeutic indices are preferred. The data
obtained from these cell culture assays and animal studies can be used in formulating a
dosage range that is not toxic for use in humans. The dosage of the β-hairpin peptidomimetics
of the invention lies preferably within a range of circulating concentrations that include the
effective dose with little or no toxicity. The dosage may vary within the range depending
upon the dosage form employed and the route of administration utilized. The exact
formulation, route of administration and dose can be chosen by the individual physician in
view of the patient's condition (see, e.g. Fingl et al. 1975, In: The Pharmacological Basis of
Therapeutics, Ch. 1, p. 1).

Examples
1. Peptide synthesis
Coupling of the first protected amino acid residue to the resin
0.5 g of 2-chlorotritylchloride resin (Barlos et al. Tetrahedron Lett. 1989,30, 3943-3946)
(0.83 mMol/g, 0.415 mmol) was filled into a dried flask. The resin was suspended in CH2Cl2
(2.5 ml) and allowed to swell at room temperature under constant stirring for 30 min. The
resin was treated with 0.415 mMol (leq) of the first suitably protected amino acid residue
(see below) and 284 μl (4eq) of diisopropylethylamine (DIEA) in CH2C12 (2.5 ml), the
mixture was shaken at 25°C for 4 hours. The resin was shaken (CH2C12 /MeOH/DIEA:
17/2/1), 30 ml for 30 min; then washed in the following order with CH2C12 (lx), DMF (lx),
CH2Cl2(1x), MeOH (1x), CH2Cl2(1x), MeOH (1x), CH2C12 (2x), Et2O (2x) and dried under
vacuum for 6 hours.
Loading was typically 0.6-0.7 mMol/g.
The following preloaded resin was prepared: Fmoc-Pro-2-chlorotritylresin.
Synthesis of the fully protected peptide fragment
The synthesis was carried out using a Syro-peptide synthesizer (Multisyntech) using
24 to 96 reaction vessels. In each vessel were placed 60 mg (weight of the resin
before loading) of the above resin. The following reaction cycles were programmed
and carried out:
Step Reagent Time
1 CH2C12, wash and swell (manual) 3x1 min.
2 DMF, wash and swell 1x5 min
3 40 % piperidine/DMF 2x5 min.
4 DMF, wash 5x2 min.
5 5 equiv. Fmoc amino acid/DMF

+ 5 eq. HCTU
+ 5 eq. DIEA 2 x 60 min.
6 DMF, wash 4 x 2 min.
7 CH2Cl2, wash (at the end of the synthesis) 3 x 2 min.
Steps 3 to 6 are repeated to add each amino-acid.
After the synthesis of the fully protected peptide fragment had been terminated, then
subsequently the cleavage, cyclization and work up procedure as described hereinbelow, was
used for the preparation of the peptides.
Analytical methods:
Method 1: Analytical HPLC retention times (RT, in minutes) were determined using an
Jupiter Proteo column (90A, 150x 2.0 mm, cod. 00F4396-B0 - Phenomenex) with the
following solvents A (H2O + 0.1% TFA) and B (CH3CN + 0.1% TFA) and the gradient: 0
min: 95%A, 5%B; 20 min: 40%A 60%B; 21-23 min: 0%A, 100%B; 23.1-30 min: 95% A,
5%B.
Method 2: Analytical HPLC retention times (RT, in minutes) were determined using an
Aquity UPLC BEH C18 column (1.7 μm, 100 x 2.1 mm, cod. 186002352 - Waters) with the
following solvents A (H2O + 0.1% TFA) and B (CH3CN + 0.085% TFA) and the gradient: 0
min: 95%A, 5%B; 0.2 min: 95%A 5%B; 4 min: 35%A, 65%B; 4.2 min: 5% A, 95%B; 4.25
min: 95%A, 5%B; 4.9 min: 95%A, 5%B.
Procedure: Cleavage, cyclization and work up of backbone cyclized peptides
Cleavage, backbone cyclization and purification of the peptide
After assembly of linear peptides, the resin was suspended in 1 ml (0.39 mMol) of 1% TFA
in CH2C12 (v/V) for 3 minutes and filtered, and the filtrate was neutralized with 1m1 (1.17
mMol, 3eq.) of 20% DIEA in CH2C12 (v/V). This procedure was repeated twice to ensure
completion of the cleavage. The resin was washed with 2ml of CH2C12. The CH2C12 layer was
evaporated to dryness.

The fully protected linear peptide was solubilised in 8 ml of dry DMF. Then 2 eq. of HATU
in dry DMF (1m1) and 4 eq. of DIPEA in dry DMF (1 ml) were added to the peptide,
followed by stirring for 16 h. The volatiles were evaporated to dryness. The crude cyclic
peptide was dissolved in 7 ml of CH2C12 and extracted with 10% acetonitrile in water (4.5
ml) three times. The CH2CI2 layer was evaporated to dryness. To fully deprotect the peptide,
3 ml of cleavage cocktail TFA:TIS:H2O (95:2.5:2.5) were added, and the mixture was stirred
for 2.5 h. The volatile was evaporated to dryness and the crude peptide was dissolved in 20%
AcOH in water (7 ml) and extracted with diisopropyl ether (4 ml) for three times. The
aqueous layer was collected and evaporated to dryness, and the residue was purified by
preparative reverse phase LC-MS.
After lyophilisation the products were obtained as white powders and analysed by HPLC-
ESI-MS analytical methods as described above. The analytical data comprising purity after
preparative HPLC and ESI-MS are shown in Table 1.
Examples 1-50, are shown in Table 1. The peptides were synthesized starting with the amino
acid L-Pro which was grafted to the resin. Starling resin was Fmoc-Pro-2-chlorotrityl resin,
which was prepared as described above. The linear peptides were synthesized on solid
support according to the procedure described above in the following sequence: Resin-Pro-
DPro-P12-Pl 1-P10-P9-P8-P7-P6-P5-P4-P3-P2-P1. Ex. 1-50, were cleaved from the resin,
cyclized, deprotected and purified as indicated by preparative reverse phase LC-MS.
After lyophilisation the products were obtained as white powders and analysed by HPLC-
ESI-MS methods as described above.

2. Biological methods
2.1. Preparation of the peptide samples.
Lyophilized peptides were weighed on a Microbalance (Mettler MT5) and dissolved in
sterile water to a final concentration of 1 mg/ml unless stated otherwise. Stock solutions
were kept at +4°C, light protected.
2.2. Antimicrobial activity of the peptides.
The selective antimicrobial activities of the peptides were determined in 96-well plates
(Nunclon polystyrene) by the standard NCCLS broth microdilution method (see ref 1,
below) with slight modifications. Innocula of the microorganisms were diluted into
Mueller-Hinton (MH) broth + 0.02% BSA and compared with a 0.5 Mcfarland standard
to give appr. 106 colony forming units (CFU)/ml. Aliquots (50 μl) of inoculate were
added to 50 μ1 of MH broth + 0.02% BSA containing the peptide in serial two-fold
dilutions. The following microorganisms were used to determine antibiotic selectivity of
the peptides: Escherichia coli (ATCC 25922), Pseudomonas aeruginosa (P. aeruginosa
ATCC 27853, P8191900, P1021903, P1021913, IMP 1 Livermore 3140). Antimicrobial
activities of the peptides were expressed as the minimal inhibitory concentration (MIC) in
μg/ml at which no visible growth was observed after 18-20 hours of incubation at 37°C.
2.3. Cytotoxicity assay
The cytotoxicity of the peptides to HELA cells (Acc57) and COS-7 cells (CRL-1651) was
determined using the MTT reduction assay [see ref. 2 and 3, below]. Briefly the method
was as follows: HELA cells and COS-7 cells were seeded at 7.0x103 and, respectively,
4.5x103 cells per well and grown in 96-well microtiter plates for 24 hours at 37°C at 5%
CO2. At this point, time zero (Tz) was determined by MTT reduction (see below).The
supernatant of the remaining wells was discarded, and fresh medium and the peptides in
serial dilutions of 12.5,25 and 50 μM were dispensed into the wells. Each peptide
concentration was assayed in triplicate. Incubation of the cells was continued for 48 hours
at 37°C at 5% CO2. Wells were then washed once with phosphate buffered saline (PBS)
and subsequently 100 μl MTT reagent (0.5 mg/ml in medium RPMI1640 and,
respectively, DMEM) were added to the wells. This was incubated at 37°C for 2 hours
and subsequently the medium was aspirated and 100 μ1 isopropanol were added to each
well. The absorbance at 595 nm of the solubilized product was measured (OD595peptide).
For each concentration averages were calculated from triplicates. The percentage of
growth was calculated as follows: (OD595peptide-OD595Tz-OD595Empty well) / (OD595Tz-
OD595Empty well) x 100% and was plotted for each peptide concentration.

The LC 50 values (Lethal Concentration, defined as the concentration that kills 50% of
the cells) were determined for each peptide by using the trend line function of EXCEL
(Microsoft Office 2000) for the concentrations (50,25,12.5 and 0 μM), the
corresponding growth percentages and the value -50, (=TREND(C50:C0,%50:%0,-50)).
The GI 50 (Growth Inhibition) concentrations were calculated for each peptide by using a
trend line function for the concentrations (50,25,12.5 and 0 μg/ml), the corresponding
percentages and the value 50, (=TREND (C50:CO,%50:%O,50).
2.4. Hemolysis
The peptides were tested for their hemolytic activity against human red blood cells
(hRBC). Fresh hRBC were washed three times with phosphate buffered saline (PBS) by
centrifugation for 10 min at 2000 x g. Peptides at a concentration of 100 μM were
incubated with 20% v/v hRBC for 1 hour at 37°C. The final erythrocyte concentration
was approximately 0.9xl09 cells per ml. A value of 0% and, respectively,. 100% cell lysis
was determined by incubation of the hRBC in the presence of PBS alone and,
respectively, 0.1% Triton X-100 in H2O. The samples were centrifuged, the supernatant
was 20-fold diluted in PBS buffer and the optical density (OD) of the sample at 540 nM
was measured. The 100% lysis value (OD540H2O) gave an OD540 of approximately 1.3-1.8.
Percent hemolysis was calculated as follows: (OD540peptide/OD540H2O) xl00%.
2.5. Plasma stability
405 μl of plasma/albumin solution were placed in a polypropylene (PP) tube and spiked
with 45 μl of compound from a 100 mM solution B, derived from 135 μl of PBS and 15
111 of 1 mM peptide in PBS, pH 7.4.150 μl aliquots were transferred into individual wells
of the 10 kDa filter plate (Millipore MAPPB 1010 Biomax membrane). For "0 minutes
controls": 270 μl of PBS were placed in a PP tube and 30 μl of stock solution B was
added and mixed. 150 μl of control solution were placed into one well of the filter plate
and served as "filtered control".
Further 150 μl of control solution were placed directly into a receiver well (reserved for
filtrate) and served as "not-filtered control". The entire plate including evaporation lid
was incubated for 60 min at 37°C. Plasma samples (rat plasma: Harlan Sera lab UK,
human plasma: Blutspendezentrum Zürich) were centrifuged at least for 2 h at 4300 rpm
(3500 g) and 15°C in order to yield 100 μl filtrate. For "serum albumin"-samples (freshly
prepared human albumin: Sigma A-4327, rat albumin: Sigma A-6272, all at 40 mg/ml
concentration in PBS) approximately 1 hour of centrifugation was sufficient The filtrates

in the receiver PP plate were analysed by LC/MS as follows: Column: Jupiter C18
(Phenomenex), mobile phases: (A) 0.1% formic acid in water and (B) acetonitrile,
gradient: 5%-100% (B) in 2 minutes, electrospray ionization, MRM detection (triple
quadrupole). The peak areas were determined and triplicate values were averaged. The
binding was expressed in percent of the (filtered and not-filtered time point 0 min) control
1 and 2 by: 100-(100 x T60/To). The average from these values was then calculated.
2.6. Pharmacokinetic study (PK)
Pharmacokinetic study after single intravenous, subcutaneous and intraperitoneal
administration in mice
Pharmacokinetic study after single intravenous (i.v.) and subcutaneous (s.c.)
administration was performed for the compound of Example 1 ("Ex. 1"). CD-1 mice (20-
25 g) were used in me study. Physiological saline was used a vehicle. The volume was 2
ml/kg i.v., and 5 ml/kg s.c. and the peptide Ex. 1 was injected to give a final intravenous
dose of 1 mg/kg, and a subcutaneous dose of 5 mg/kg. Approximately 200-230 μl of
blood was removed under light isoflurane anesthesia by cardiac puncture at
predetermined time intervals (0, 5,15, 30 min and 1,2, 3,4 and 5 hours for the i.v. study
and 0,15,30 min and 1,2,4,6,8 and 10 hours for the s.c. study) and added to
heparinized tubes. Plasma was removed from pelleted cells upon centrifugation and
frozen at -80°C prior to HPLC-MS analysis.
Preparation of the plasma calibration samples
"Blank" mouse plasma from untreated animals was used. Aliquots of plasma of 0.2 ml
each were spiked with 50 ng of propranolol (Internal Standard, IS), (sample preparation
by solid phase extraction on OASIS® HLB cartridges (Waters)) and with known amounts
of Ex. 1 in order to obtain 9 plasma calibration samples in the range 10 - 5000 nM. The
OASIS® HLB cartridges were conditioned with 1 ml of methanol and then with 1 ml of
1% NH3 in water. Samples were then diluted with 700 μl of 1% NH3 in water and loaded.
The plate was washed with 1 ml of methanol/1% NH3 in water 5/95. Elution was
performed using 1 ml of 0.1% TFA in methanol.
The plate containing eluates was introduced into the concentrator system and taken to
dryness. The residues were dissolved in 100 μL of formic acid 0.1%/acetonitrile, 95/5
(v/v) and analysed in the HPLC/MS on a reverse phase analytical column (Jupiter C18,
50 x 2.0 mm, 5 μm, Phenomenex), using gradient elution (mobile phases A: 0.1% formic
acid in water, B: Acetonitrile; from 5%B to 100%B in 2 min.).

Preparation of plasma samples
Samples coming from animal treatments were pooled in order to obtain an appropriate
volume for the extraction. If the total volume obtained was less than 0.2 ml the
appropriate amount of "blank" mouse plasma was added in order to keep the matrix
identical to the calibration curve. Samples were than spiked with IS and processed as
described for the calibration curve.
Pharmacokinetic evaluation
PK analysis was performed on pooled data (generally n=2 or 3) using the software Win
Nonlin (Pharsight). The area under the curve AUC was calculated by the linear
trapezoidal rule. Elimination half-life was calculated by the linear regression on at least
three data points during the elimination phase. The time intervals selected for the half-life
determinations were evaluated by the correlation coefficient (r2), which should be at least
above 0.85 and most optimally above 0.96. In case of i.v. administration the initial
concentration at tzero was determined by extrapolation of the curve through the first two
time points. Finally bioavailability after i.p. administration was calculated from the
normalised AUCinf_D_obs ration after s.c. versus i.v. administration.
2.7. In vivo Septicemia Assay
Groups of 6 CD-1 (Cr1.) derived male mice weighing 24 ± 2 g were used. The mice were
each inoculated intravenously (TV) with an LD90-100 of Pseudomonas aeruginosa
(ATCC 27853) (9 x 106 CFU/0.5ml/mouse) in brain heart infusion broth without 5%
mucin. Compound at doses of 5, 2.5, 1, 0.5, 0.25 and 0.1 mg/kg, vehicle (0.9% NaCL, 10
ml/kg) was administered subcutaneously (SC) to test animals at 1hour after bacterial
inoculation. Also, an additional group was treated twice with compound at a dose of
5mg/kg at 1 and 6 hours after bacterial inoculation. Mortality was recorded once daily for
7 days following the bacterial inoculation and an increase of survival of the animals by 50
percent or more (3 50 %) after the bacterial inoculation, relative to vehicle control,
indicates significant antimicrobial effect. The MED (ED50) was determined by nonlinear
regression using Graph-Pad Prism (Graph Pad Software, USA).
2.8. Results
The results of the experiments described in 2.2,2.3 and 2.4, above, are indicated in Table
2, herein below








After intravenous administration of Ex. 1 at a dose level of 1 mg/kg body weight, Ex. 1
followed intravenous kinetic characteristics. After PK analysis, Ex 1 showed an
extrapolated Cinitial of 2174 ng/ml and a Cmax observed of 1268 ng/ml at 5 min. Plasma
levels rapidly decreased to 575 and 177 ng/ml at 15 min and 1 hour respectively. From

0.5 to 2 h plasma levels decreased with an elimination half-life of 0.53 h to 10.6 ng/ml at
3 h. The AUCINF_obs amounted to 679.5 ng.h/ml.
After subcutaneous administration of Ex. 1 at a dose level of 5 mg/kg body weight,
plasma levels of Ex. 1 increased the first 0.5-1 h and showed a Cmax of 2333 ng/ml. From
0.5 to 8 h plasma levels decreased with an elimination half-life of 0.95 h to 7.3 ng/ml at 8
h. The AUCINF_obs amounted to 4016.5 ng.h/ml.
As compared to the normalized AUC value after i.v. administration (100% absorbed, 679
ng.h/ml) of Ex. 1 absorbed after s.c administration amounted to 118% (803 ng.h/ml). The
value above 100% may partially reflect an impaired reliability caused by the limited
number of points or is caused by a non-linearity in dose.
The results of the experiment described in 2.7 (Septicaemia Assay), above, are indicated
in Table 5-7 herein below.

the chain of amino acid residues and, if desired, any protecting group(s) which may in
addition be present in the molecule; and
(s) if desired, converting the product thus obtained into a pharmaceutically acceptable
salt or converting a pharmaceutically acceptable, or unacceptable, salt thus obtained into
the corresponding free compound of formula I or into a different, pharmaceutically
acceptable, salt.
45. A process for the manufacture of compounds according to any one of claims 1-34
which process comprises
(a') coupling an appropriately functionalized solid support with a compound of the
general formula


is as defined in claim 1 and X is an N-protecting group or, if

is to be group (a1) or (a2), as defined in claim 1, alternatively
(a'a) coupling said appropriately functionaliZed solid support with an
appropriately N-protected derivative of an amino acid of the general formula
HOOC-B-H III or HOOC-A-H IV
wherein B and A are as defined in claim 1, any functional group which may be
present in said N-protected amino acid derivative being likewise appropriately
protected;
(a'b) removing the N-protecting group from the product thus obtained; and
(a'c) coupling the product thus obtained with an appropriately N-protected
derivative of an amino acid of the above general formula IV and, respectively, III,
any functional group which may be present in said N-protected amino acid
derivative being likewise appropriately protected;
(b') removing the N-protecting group from the product obtained in step (a') or (a'c);
(c') coupling the product thus obtained with an appropriately N-protected derivative of
that amino acid which in the desired end-product is in position 12, any functional group
which may be present in said N-protected amino acid derivative being likewise
appropriately protected;
(d') removing the N-protecting group from the product thus obtained;
(e') coupling the product thus obtained with an appropriately N-protected derivative of
that amino acid which in the desired end-product is one position farther away from
position 12, any functional group which may be present in said N-protected amino acid
derivative being likewise appropriately protected;
(f) removing the N-protecting group from the product thus obtained;
(g1) repeating steps (e') and (f) until all amino acid residues have been introduced;
(h') if desired, selectively deprotecting one or several protected functional group(s)
present in the molecule and appropriately substituting the reactive group(s) thus liberated;
(i') detaching the product thus obtained from the solid support;
(j') cyclizing the product cleaved from the solid support;

(k') if desired forming one or two interstrand linkages) between side-chains of
appropriate ammo acid residues at opposite positions of the P-strand region;
(I') removing any protecting groups present on functional groups of any members of
the chain of amino acid residues and, if desired, any protecting group(s) which may in
addition be present in the molecule; and
(m') if desired, converting the product thus obtained into a pharmaceutically acceptable
salt or converting a pharmaceutically acceptable, or unacceptable, salt thus obtained into
the corresponding free compound of formula I or into a different, pharmaceutically
acceptable, salt
46. A modification of the process of claim 44 or 45 for the manufacture of compounds
according to claim 35 in which enantiomers of all chiral starting materials are used.

Template-fixed β-hairpin peptidomimetics of the general formula (I) wherein Z is a template-fixed chain of 12 α-amino acid residues which, depending on their positions in the chain
(counted starting from the N-terminal amino acid) are Gly, or Pro, or of certain types which, as the remaining Symbols in the above formula, are defined in the description and the claims, and salts thereof, have the property to selectively inhibit the growth of or to kill microorganisms such as Pseudomonas aeruginosa. They can be used as disinfectants for foodstuffs, cosmetics, medicaments or
other nutrient-containing materials, or as medicaments to treat or prevent infections. These β-hair-pin peptidomimetics can be manufactured by processes which are based on a mixed solid- and Solution phase synthetic strategy.
