Full Text FIELD OF INVENTION
The present invention provides compounds of Formula (I), compositions thereof,
and a method of antagonizing the NK-1 subtype of tachykinin feceptor that comprises
administering to a patient in need thereof an effective amount of a compound of Formula
(I). In addition, the present invention relates to processes for preparing the compounds of
Formula 1 and intermediates thereof.
BACKGROUND OF THE INVENTION
Techykinins are a femily of neotides that are widely distributed in both the central
and peripheral nervous systems. These peptides exert a number of biological effects
throuch actions at tachykinin receptors. To date, three such receptors have been
characterized, including the NK-1, NK-2, and NK-3 subtypes of tachykinin receptor.
The role of the NK-1 receptor subtype in numerous disorders of the central
nervous system and the periphery has been thoroughly demonstrated in the art. For
instance, NK-3 receptors arc believed to play a role in depression, anxiety, and central
regulation of various autonomic, as well as cardiovascular and respiratory functions, NK-
1 receptors in the spinal cord are believed to play a role in pain transmission, especially
the pain associated with migraine and arthritis. In the periphery, NK-1 receptor activation
has been implicated in numerous disorders, including various inflammatory disorders,
asthma, and disorders of the gastrointestinal and genitourinary tract.
There are a actrictive which recognion; that selectiv NK) receptor antagonists.
would prove useful in the treatmem of many diseases of the central nervous system and
the periphery. While many of these disorders are being treated by new medicines, there
are still many shortcomings associated with existing treatments. For example, the newest
class of anti-depressants, selective serotonin reuptake inhibitors (SSRIs), are increasingly
prescribed for the treatment of depression; however, SSRIs have numerous side effects,
including nausea, insomnia, anxiety, and sexual dysfunction. This could significantly
affect patient compliance rate. As another example, current treatments for chemotherapy-
induced nausea and emesis, such as the 5-HT3 receptor antagonists, are ineffective in

managing delayed cmests. The development of NK-1 receptor antagonists will therefore
greatly enhance the ability to treat such disorders more effectively. Thus, the present
invention provides a class of potent, non-peptidc NK-1 receptor antagonists, compositions
comprising these compounds, and methods of using the compounds.

Schemes
The compounds disclosed herein can be made according to the following schemes
and examples. The examples should in no way be understood to be limiting in any way as
to how the compounds may be made.

The skilled artisan will appreciate that the introduction of certain substituents will create
asymmetry in the compounds of Formula (I). The present invention contemplates all
enantiomers and mixtures of enantiomers, including racemates. It is preferred that the
compounds of the invention containing chiral centers are single enantiomers.
The compounds: of the present invention can be prepared by a variety of
procedures, some of which are illustrated in the Schemes below. It will be recognized by
one of skill in the art that the individual steps in the following schemes may be varied to
provide the compounds of Formula (I). The particular order of steps required to produce
the compounds of Formula (I) is dependent upon the particular compound being
synthesized, the starting compound, and the relative lability of the substituted moieties.

In Scheme 1. the triazole compounds of Formula (3) are formed by reacting a beta,
keto estei of Formula (2), such as a beta keto C1-C6 alkyl or benzyl ester, with an azide of
Formula (1). Such ring formations are well known and appreciated in the art. See Savini
et al., Farmaco (1994) 49(5): 363-370; Martini et al., J. Phann. Sci. (198S) 77(11): 977-

isolated and purified by techniques well known in the art, such as precipitation, filtration,,
extraction, evaporation, trituration, chromatography, and recrystallization.
Azides of Formula (1) are commercially available or can be synthesized from the
corresponding halide or sulfonate ester derivatives by reaction with an azide source, such
as NaN3, LiN3, or tetrabutyl ammonium azide (BU4NN3), with NaN3 being preferred in a
suitable solvent mixture as DMSO and water.
Alternatively, the skilled artisan would also appreciate that a malonate derivative
maybe used in the reaction of step a, instead of a beta keto ester. Both the malonates and
the beta keto esters are well known and appreciated in the art. See Benetti, S.; Romagnoli,
R.; De Risi, C; Zanirato, Z "Mastering (3-Keto Esters," Chem. Rev. 1995, 95, 1065-1114.
When dialkylmalonates are chosen as the starting reagent, R5 in the resulting
product of Formula (3) is a hydroxyl group. The hydroxyl 'group may be readily
converted to the corresponding halide intermediate. This type of transformation is well
known and appreciated in the art. See Buckle, D. R.; Rockell, C. J. M. J. Chem. Soc,
Perkin I, 1982, 627-630.
Step b depicts the reduction of lH-[1,2,3]triazole-4-carboxylic acid ester of
Formula (3) to give a lH-[1,2,3]triazol-4-yl-methanol of Formula (4). Such reduction
steps are well known and appreciated in the art. See Larock, R. C, Comprehensive
Organic Transformations, 2nd Ed., copyright 1999, John Wiley & Sons, pp 1117-1120.
In one variation of step b, the 1H-[1,2,3]triazole-4-carboxylic acid ester of
Formula (3) may be reduced by a suitable reducing agent, such as sodium borohydride,
lithium aluminumhydride, lithium borohydride, or diisobutyl aluminumhydride, with
sodium borohydride being the preferred reducing agent. Such reductions are generally
camed out m a solvent such as MeOH, LtOh. iPrOH THI . toluene, methylend chlonde.
or mixtures thereof. The preferred solvent is absolute ethanol. The product can be
isolated and purified by techniques described above.
Oxidation of an alkyl-hydroxy group of Formula (4) is well known in the art. A
representative example is shown in step c, in which the lH-[1,2,3]triazol-4-yl-methanol of
Formula (4) can be oxidized by reacting it with an appropriate oxidizing agent, such as
manganese oxide. Other oxidizing agents include pyridine sulfurtrioxide complex, 1,1.1-
triacetoxy-l,l-dihydro-l,2-benziodoxol-3(lH)-one (Dess-Martin reagent), pyridinium

chlorochromate, pyridinium dichromate, and catalytic tetrapropylarrunonium perruthenate
(TPAP) with N-methylmorpholine N-oxide (NMO) as a co-oxidant. The aldehydes of
Formula (5) can be isolated by techniques described above.
Hydrolysis of the carboxyl esters of Formula (3) to give the corresponding
carboxylic acids of Formula (6) is well known reaction. See Larock, R. C,
Comprehensive Organic Transformations, 2nd Ed., copyright 1999, John Wiley & Sons,
pp 1959-1968. For example, an appropriate ester of Formula (3) is dissolved in a suitable
solvent, such as methanol or dioxane and water, and treated with a suitable base, such as
NaOH or LiOH, to give a compound of Formula (6).
The reaction of step e, in which a carboxylic acid, such as that of Formula (6), is
coupled with an appropriate amine, under standard peptide coupling conditions, is well
known to the skilled artisan. Specifically, the amine and the carboxylic acid are coupled
in the presence of a peptide coupling reagent, optionally in the presence of a catalyst. .
Suitable peptide coupling reagents include N,N'-carbonyldiiraidazo]e (CDI), N,N'-
dicyclohexylcarbodiimide (DCC), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide
hydrochloride (EDC), and 1-(3-(1-pyrrolidinyl)propyl)-3-ethylcarbodiimide (PEPC).
Suitable catalysts for the coupling reaction include N,N-[dimethyl3-4-aminopyridine
(DMAP). Such coupling reactions are well known and appreciated in the art. See Larock,
R. C, Comprehensive Organic Transformations, 2nd Ed., copyright 1999, John Wiley &
Sons, pp 1941-1949.
Alternatively, a compound of Formula (6) may be converted to an acid chloride
derivative, preferably by reaction with oxalyl chloride and DMF, and used to acylate the
appropriate amine to give a compound of Formula (7). Such acylation reactions are well
known and appered in the art SEC Lamond R Comprehemer Organ
Transformations, 2nd Ed., copyright 1999, John Wiley & Sons, pp 1929-1930. The
product can be isolated and purified by techniques described above.
One skilled in the art could also appreciate the formation of the amides of Formula
(7) by a direct conversion of the carboxyl ester of Formula (3) by the use of a trialkyl-
aluminum reagent with an appropriate amine or by use of a magnesium amide to afford
compounds of Formula (7). Formula (7) can further undergo a reduction, step g, by
treatment of a suitable reducing agent, such as diisobutylaluminiun hydride, lithium
aluminum hydride or a borane-methyl sulfide complex to afford aldehydes of Formula (5).


The alkynyl-ketones of Formula (9) can be synthesized from the aldehydes of
Formula (5) (see Scheme 1) or the N-methyl-N-methoxyamide derivatives of Formula
(10).
Step h depicts the addition of an alkynyl anion to an aldehyde of Formula (5) or a
N-methyl-N-methoxyamide of Formula (9). The alkynyl anion is generated by treating the
appropriate alkyne with a suitable base, such as methyl lithium, n-butyl lithium, tert-buty]
lithium, lithium diisopropylamine, preferably methyl or ethyl magnesium bromide. Wher
the aldehydes of Formula (5) are used, the hydroxy intermediate, Formula (8), can be
oxidized to afford the ketone of Formula (9). Such reactions are well known in the art.
See Larock, R.C., Comprehensive Organic Transformations, 2nd ed, Wiley-VCH: New
York, 1999, pp 1234-1246. Alternatively, when the N-methyl-N-methoxyamide
derivatives of Formula (10) are used compounds of Formula (9) are obtained directly.


Stannaries of Formula (13) can be made from the reaction of an appropriate azide,
Formula (1), with an appropriate starmyl-acetylene of Formula (12). The reactants are
combined in a suitable solvent, such as benzene, chloroform, THF, preferably toluene,
and heated until the reaction is complete. The compound of Formula (13) is isolated and
purified by techniques known in the art and described above.
The stannyl-acetylenes of Formula (12) are readily available from commercial
sources or can be prepared from compounds of Formula (11) or (14). A compound of
Formula (11) may be dissolved in an appropriate solvent, such as THF, followed by
addition of bis(tributyl)tin oxide and an appropriate desilylating agent, such as TBAF
(tetrabutyl ammonium fluoride), or potassium trimethylsilanolate. Alternatively, the
compound of Formula (1.2) is made by dissolving an alkyne in an appropriate solvent,
such as ether or THF, at -15 to -10 °C. To this mixture is added nBuLi, followed by
tributyltin chloride. The compound of Formula (12) may be used directly or isolated and
purified by techniques described above
The formation of various stannyl acetylenes of Formula (12) has been described
elsewhere. For example, see WO 00/51614; WO 00/01702; WO 9S/46228; Lambert et
al., Journal of the Chemical Society, Perkin Transactions 2 (2001) 6: 964-974;

5822-23; and Jacobi et al., Journal of the American Chemical Society (2000), 122(18):
4295-4303.

The silyl-acetylenes of Formula (11) are readily available from commercial
sources. Alternatively, the skilled artisan will recognize that compounds of Formula (11)
may be prepared by reacting an appropriate aryl halide compound with trimethylsilyl
acetylene to give the silyl-alkyne. The reaction proceeds in the presence of copper iodide
and a palladium catalyst, such as dichlorobis(triphenyl-phosphine)palladium (U)- Other
suitable catalysts include Pd(Ph3)4, Pd2dba3.CHCl3, or Pd(OAc)2.

To make the compound of Formula (17), where L can be a halide, trimethylsilyl
(TMS) or trifluoromethanesulfonate (triflate), preferably a bromide, a heteroaryl of
Formula (18) is heated with a suitable base, such as LDA (lithium diisopropyl amide) or
LiTMP (lithium tetramethylpiperidine), in a suitable solvent, such as ether, or preferably
THF, and then reacted with a commercially available aldehyde, step n, to give the
substituted heteroaryl of Formula (17). in which X is -CH(OH). Compounds of Formula

Alternatively, for compounds of Formula (17) in which A2 and A4 are both
nitrogen, the 5-bromopyrimidine of Formula (18) and a commercially available aldehyde
are dissolved in a suitable solvent, such as ether, and heated to reflux. A suitable base
such as LDA is added to afford the compound of Formula (17), which may be isolated
and purified by techniques described above. See reference: Kress, T. J., J. Org. Chew.,
1979, 44(13), 2081-2082. One skilled in the art would appreciate the use of an

appropriate substituted disulfide compound, of the form R6-X-X-R6, instead of an
aldehyde, to also afford compounds of Formula (17), where X is a sulfur.
Compounds of Formula (17) in which X is -CH(OH)- can be oxidized by
techniques well known in the art to give a ketone of Formula (17), in which X is -C(O)-.
For instance, the alcohol may be dissolved in a suitable solvent, such as toluene or
CH2Cl2, followed by addition of MnO2- The ketone can be isolated and purified by
techniques that are well known in the art. It will be generally recognized that other
oxidizing conditions can be used to give the compound of Formula (17), in which X is -
C(O)-. For example, oxidation can be achieved by use of Dess-Martin periodinane.
Other oxidizing conditions are well known in the art. See Larock, R.C.,Comprehensive
Organic Transformations, 2nd ed, Wiley-VCH: New York, 1999, pp 1234-1246.
As shown in step m, ketones of Formula (17) in which A1 and A2 are both
nitrogen can alternatively be made by reacting the dihydropyridazinone of Formula (15)
with the appropriate aldehyde of Formula (19) in the presence of a suitable base, such as
NaOH, or KOH, in a suitable solvent, such as MeOH or EtOH. The preferred
combination is KOH in EtOH. The compound of Formula (16), in which X is methylene,
is isolated and purified by techniques well known in the art and described above. The
methylene can be further oxidized to give a compound of Formula (16) in which X is -
C(O)- by treating with a solution of acetic acid and sodium dichromate and heating. The
hydroxy pyridazine of Formula (16) is then combined with a brominating agent, such as
phosphorous oxybromide to give a compound of Formula (17), which is isolated and
purified as described above. See references Kandile, N., Acta Chimica Hungarica., 1990.

In Scheme 5, Route 1, compounds of Formula (I) in which each of A1, A2, A3, and
A4 is CR8may be prepared from compounds of Formula (23), wherein X is -C(O)-. The
skilled artisan will recognize that conditions for preparation of such aryl groups are well
known in the art. For example, a compound of Formula (23) in which X is -C(O)- may
be reacted in chlorobenzene with pyrone to give compounds of Formula (24), in which
A1. A2. A3, and A are each -CH- The produser of formula The conventaly punfied by
techniques well known to the skilled artisan, such as silica gel chromatography.

propyl)-phosphonic acid dimethyl ester, to give an alkyne of Formula (23). The reaction
is carried out in an appropriate solvent, such as MeOH or EtOH. The skilled artisan will

alkynes of Formula (22) using a reaction similar to that described in Scheme 2 above.

Furthermore, a compound of Formula (23), in which X is -CH(OH)-, may be oxidized to

In Scheme 5, Route 2, step p, a palladium catalyst, such as Pd(PPh3)4,
Pd2dba3•CHCl3, Pd(OAc)2, or dichlorobis(triphenylphosphine) palladium is added to a
degassed solution of the halide or triflate of Formula (17) and the stannane of Formula
(13). The preferred palladium catalyst for the reaction of step p is Pd2dba3•CHCl3. The
reaction is carried out in a suitable solvent, such as benzene, toluene, or, preferably, DMF,
in a sealed vessel under N2. The product of Formula (24) can be isolated and purified as

appropriate solvent, such as benzene or toluene, and an alkyne or alkynyl-stannane is
added. The reaction proceeds in the presence of a palladium catalyst, such as
Pd(PPh3)2Cl2, Pd2dba3•CHCl3, or tetrakis(triphenyl-phosphine)palladium, alone or in

alkyne of Formula (9) with a nitrile oxide, generated by combining an appropriately
substituted nitroalkane in the presence of an isocyanate and a base, such as triethylamine,
or by combining an optionally substituted chloro-oxime in the presence of triethylamine,
to afford compounds of Formula (25) in which Q3 and Q4 are N and O respectively. For
examples of such-cyclizations see Jouled A Mills. K. Hrtrmrovcl Chenustry 4th ed

deprotected as shown in step u. The protected alcohol is dissolved in a suitable solvent,
such as MeOH or EtOH, and treated with an acid, such as p-TsOH•H2O (para-toluene
sulfonic acid) or CSA (camphor sulfonic acid). Alternatively, the alcohol may be
liberated by heating with a mixture of THF, water, and acetic acid. The product is

isolated and purified as described previously, or can be used without purification. For
compounds of Formula (25) or (26) when R5 is a halide, such as a chloride, a substitution
can be performed with an appropriate nucleophile such as, but not limited to, primary
amines, secondary amines, alcohols or thiols to further encompass compounds of Formula

CH2Cl2. These and other oxidizing conditions are described in Larock, R.C.,
Comprehensive Organic Transformations, 2"d ed., Wiley-VCH: New York, 1999, pp
1234-1246. A skilled artisan could also use an acetal group, instead of the hydroxy group
of Formula (26), to produce aldehydes of Formula (27) by treating the acetal containing
compound under aqueous acidic conditions.
Compounds of Formula (I) in which both Q1 and Q2 are nitrogen may be prepared
from aldehydes of Formula (27), in which RX is a bond, by conditions well known in the

R is 2,2-dimethoxy-ethyl or 2,2-diethoxy-ethyl, the acetal is dissolved in a mixture of
acetone/water, and a suitable acid, such as p-TsOH, CSA, or HC1, is added. Alternatively,
as the skilled artisan will recognize, the reaction may be carried out in a pressure vessel in
a mixture of acetic acid and water mixture. The product of Formula (30) is isolated and
purified by techniques well known in the art, and as described above.
R' may also be an alcohol protected with a suitable protecting group, such as THP
or trimethylsilanr FOT such compound? of Formula (29). the protected alcohol is do-
protected and lurther oxidized substantially by steps u and v, discussed above in Route 1.

Formula (9) and azides of Formula (1) by the reaction conditions previously described in
Scheme 3, step k.
The aldehyde of Formula (30) may be transformed to a compound of Formula (I)
in which R4 is a radical of Formula (IF), as shown in step y. An appropriate source of
ammonia, such as ammonium acetate or ammonia, is added to a solution of the aldehyde
of Formula (30) in an appropriate solvent, such as acetic acid. Other suitable solvents are

an N-O bond cleavage to give compounds of Formla (31) m which P is a radical of
Fonnula (1A) and in which A2 is -CH- and A- is -CR8-, wherein R8 is NH2. Such a
reaction is depicted in Scheme 7, step z. Specifically, the bicyclic isoxazole is dissolved
in a suitable solvent, such as acetonitrile. To the reaction, is added molybdenum
hexacarbonyl and water. The skilled artisan will recognize that the solution may be
heated for the reaction to proceed. The product of Fonnula (32) is purified by techniques
well known in the art, such as silica gel chromatography or recrystallization. Such
reactions have been described in the art. See Nitta et al., J. Chem. Soc, Chem. Commun.

pressure sealed vessel.
As shown in step aa, the amino-substituted compound of Formula (3.2) may
undergo deamination to give a compound in which A3 and A4 are both -CH-. The amine

convenient solvent such as methanol to provide compounds of Formula (36) Such
reactions are well known in the art. See Bousquet, E. W., Org Syn 1943, II, 312.
Compounds of Formula (36) may be treated with a chlorinating agent such as N-
chlorosuccinimide in a suitable solvent such as dimethylformamide to provide
hydroxyimidoyl chlorides of Formula (37). This reaction is also well known in the art.

Oxidation conditions may include the use of sulfur trioxide pyridine complex with the
addition of a base such as triethylamine. The reaction is carried out in an appropriate

One skilled in the art would also appreciate the formation of the compounds of
Formula (I) in which -Gl-G2-G3- is -N-CR8-NH-. A representative example of this
formation is shown in Scheme 13. Step pp depicts the condensation of the aldehydes of
Fonnula (5) with a methylene-(toluene-4-sulfonyhnethyl)-amine intermediate of Formula
(53) in the presence of sodium cyanide in a suitable solvent such as N,N-
dimethylformamide or ethanol The conespending 4-uohieni-4-sulfonnyl -4-dihydro
oxazole intermediate, Formula (54), can be transformed to the imidazole compounds of
Formula (I), by heating with a mixture of an ammonia alcohol solution in a high boiling
solvent such as xylenes, chlorobenzene or toluene. The transformation to the imidazole is
well known and appreciated in the art. See Buchi, G. Heterocycles, 1994, pg. 139; Van
Leusen, A. M. Tetrahedron Lett. 1972, pg. 2369. The appropriate methylene-(toluene-4-

The skilled artisan will recognize that the resulting hydroxy] group of R8 can be
oxidized to give compounds of Formula (57), which are encompassed in Formula (I),
where Rx is a bond or a methylene group, and in which R8 is an oxo-substituted alkyl.
The alcohol can be oxidized by many different oxidizing reagents such as under Dess-
Martin periodinane oxidizing conditions or using combination of DMSO and
triethylamine with oxalyl chloride. Such oxidations are readily accomplished by methods
well known in the art. (Larock , R.C., Comprehensive Organic Transformations, 2nd ed.,
Wiley-VCH: New York, 1999, pp 1234-1246). The product of the reaction can be isolated
and purified using techniques well know in the art.
Compounds of Formula (57) in which R8 is an oxo-subsnmted alkyl group can
also be made by deprotection of the appropriate acetal. Such deprotections are readily
accomplished by methods well known in the art. (Protecting Groups in Organic Synthesis,
Theodora Greene (Wiley-Interscience)). For example, a compound in which R8 is
dimethoxy-acetal is reacted under aqueous acidic conditions to give a compound of
Formula (57) in which R8 is an aldehyde or an acetaldehyde.
Compounds of Formula (I) can be synthesized by reacting the appropriate
aldehyde-containing compound of Formula (57) with ammonium acetate or hydrazine
under acidic conditions such acetic acid. When Rx is a methylene group, ammonium

acetate is the reactant, to provide compounds of Formula (I) in which Q5 is -CR8- and Q6
is nitrogen are achieved or with hydrazine as the reactant, when Rx is a bond, compounds,
of Formula (I) in which Q5 and Q6 are nitrogen are achieved.

Route 1 of Scheme 16 depicts the formation of compounds of Formula (63), which
are encompassed in Formula (I), by the reaction of a diamine of the Formula (60) and '
esters of the Formula (3). It is understood that this reaction can occur when Rx is either a
bond or methylene, to give compounds of Formula (I) in which R4 is a radical of Formula
(IG) or (M), respectively. The reaction can be carried out in the presence of an
appropriate solvent such as toluene or benzene. A solution of the diamine in toluene is
treated with trimethylaluminum and then the appropriate ester is added as a solution in the
appropriate solvent such as toluene or benzene. The reaction is heated until the reaction is
complete. The product of the reaction can be isolated and purified using techniques well
know in the art. These techniques include extraction, evaporation, chromatography, and
recrystallization. The compounds of Formula (60) can be prepared by reductive
animation reactions, generally by combining a N-protected-amino-aldehyde with an
appropnok annnu of alternate and skilds the caries a mono-protect:
diamine with an appropriate aldehyde, and a suitable reducing agent such as
triacetoxysodium borohydride, sodium cyanobohydride or sodium borohydride.
Appropriate solvents may include methanol, 1,2-dichloroethane or ethanol. A leading
reference that can be consulted for reaction conditions is Larock , R.C., Comprehensive
Organic Transformations, 2nd ed., Wiley-VCH: New York, 1999, pp S35-846. This may
be followed by deprotection of the protecting groups.

Allcylations of this type are well known in the literature. An appropriate solvent for such
reactions is dirnethylforrnamide. A suitable non-nucleophilic base may include potassium
carbonate. Sodium iodide is added in a catalytic amount.

which Rx is a bond) maybe further aromatized to give compounds of Formula (63) in
which R4 is a radical of Formula (IC) and -G4-G5-G6- is -N-CR8-CR8-, which are

encompassed in Formula (I). The dehydrogenation conditions include dissolving the
imidazoline in a solvent such as xylenes and adding a palladium catalyst such a 10%
palladium on carbon. The dehydrogenation reaction is allowed to heat until the reaction is
complete. A reference for the dehydrogenation conditions is Amemiya, Y.; Miller, D.D.;
Hsu, F.L.; Synth. Comm. 1990, Vol 20 (16) 2483-2489. The pioduct of the reaction can

NK-1 Receptor Binding Assay
The IM cell line is a well-characterized and readilv available human cell line
See, e.g.. Annak oi the New York Acadeny of Science. 190. 224, -234 (1972); Nanire
(London), 251:443-444 (1974); Proceedings of the National Academy of Sciences (USA),
71:84-88 (1974). These cells are routinely cultured in RPMI 1640 supplemented with 50
Hg/ml gentamicin sulfate and 10% fetal calf serum.
The IM-9 cells are homogenized from cell pellets for crude membranes. The
membranes are isolated by homogenizing tissue samples in 30 ml w/v with 50 mM Tris
buffer (pH 7.4). After an initial spin at 900 x g, the supernatant is transferred to a clean
centrifuge tube and the membranes isolated by centrifugation at 3S,000 x g.

Approximately 25 µg of membranes are incubated with 0.2nM [125I]-substance P
(NEN, Boston, MA) in a receptor binding assay. The assay buffer contains 50 mM Tris,'3
mM MnCl2, 0.02% bovine serum albumin, 40 ug/ml bacitracin, 2 ug/ml chymostatin, 4
ug/ml leupeptin and 40 µg/ml thiorphan (pH 7.4). Binding studies are conducted in a
final volume of 200 µl containing various concentrations of test compounds. Non-
specific binding is determined by incubating some rubes in the presence of 1 uM
substance P (Peninsula, Belmont, CA).
Binding is terminated 1 hour later by rapid filtration using a TOMTEC 96-well
cell harvester (TOMTEC, Orange, CT) through GF/A filters that have been presoaked
with 0.3% polyethyleneimine (Sigma, St Louis) for 1 hour. The filters are washed with 5
ml of ice-cold 50 mM Tris buffer (pH 7.4) and placed in a drying oven at 60°C. The dried
filters are treated with MeltiLex A melt-on scintillator sheets (Wallac, Gaithersburg, MD),
and the radioactivity retained on the filters counted using the Wallac 1205 Betaplate
scintillation counter. The results are analyzed using a Log-Logit plot from a Microsoft
Excel workbook and converted to Ki values with the Cheng-Prusoff equation. Protein
concentrations are measured using Coomassie® protein assay reagent (Pierce, Rockford,
IL), with BSA for standards (Bradford, 1976).
Binding studies are carried out to evaluate the ability of compounds of the present
invention to inhibit NK-1 receptor activation. Such studies provide in vitro data regarding
the efficacy of the compounds of the present invention. Compounds described herein as
EXAMPLES have been demonstrated to have binding affinities (Kj values) of The results of NK-1 receptor binding studies demonstrate the ability of
compounds of the present invention to act as antagonists of NK-1 receptors. It is
recognzed that the conpounds of the presents cannan would be expected inhibit the
effects of NK-1 receptor activation. Thus, the compounds of the present invention are
expected to be useful in the treatment of various disorders associated with excess
tachykinins, as described to be treated herein, and other disorders that can be treated by
such antagonists, as are appreciated by those skilled in the art.
In one embodiment, the present invention provides methods of treating disorders
selected from the group consisting of anxiety, depression, psychosis, schizophrenia and
other psychotic disorders, neurodegenerative disorders (including senile dementia of the
Alzheimer's type, Alzheimer's disease, AJDS-associated dementia, and Down's

syndrome), demyelinating diseases (including multiple sclerosis and amyotrophic lateral
sclerosis), neuropathological disorders (including peripheral neuropathy, diabetic and
chemotherapy-induced neuropathy, and post-herpetic and other neuralgias), acute and
chronic obstructive airway diseases (including adult respiratory distress syndrome,
bronchopneumonia, bronchospasm, chronic bronchitis, drivercough, and asthma),

fascioliasis), irritative symptoms of benign prostatic hypertrophy, disorders associated
with blood pressure (such as hypertension), disorders of blood flow caused by
vasodilation or vasospastic diseases (such as angina, migraine, and Reynaud's disease),
emesis (including chemotherapy-induced nausea and acute or delayed emesis), and pain or
nociception (including that attributable to or associated with any of the foregoing
conditions), comprising: administering to a patient in need thereof an effective amount of
a compound of formula or a phanmacai. composmon there. that is the present
invention provides methods of treating disorders associated with an excess of tachykinins,
comprising: administering to a patient in need thereof an effective amount of a compound
of Formula I or a pharmaceutical composition thereof.
The present invention contemplates the various disorders described to be treated
herein and others that can be treated by such antagonists, as appreciated by those skilled
in the art.

The disorders associated with an excess of tachykinins are treated by
administering an effective amount of a compound or phannaceutical composition o
Formula I. An effective amount can be readily determined by the attending diagnostician,
as one skilled in the art, by the use of conventional techniques and by observing results
obtained under analogous circumstances. In determining an effective amount, the dose-of
a compound of Formula I, a number of factors are considered by the attending
diagnostician, including, but not limited to: the compound of Formula I to be
administered; the species of mammal - its size, age, and general health; the specific
disorder involved; the degree of involvement or the severity of the disorder; the response
of the individual patient; the mode of administration; the bioavailability characteristics of
the preparation administered; the dose regimen selected; the use of other concomitant
medication; and other relevant circumstances.
An effective amount of a compound of Formula I is expected to vary from about
0.001 milligram per kilogram of body weight per day (mg/kg/day) to about 100
mg/kg/day. Preferred amounts may be readily determined by one skilled in the art.
Of the disorders associated with an excess of tachykinins that are treated according
to the present invention, the treatment of depression and anxiety are particularly preferred.
Thus, in a preferred embodiment, the present invention provides a method for
treating a depressive disorder, including major depressive disorder, comprising:
administering to a patient in need thereof an effective amount of a compound of Formula I
or a pharmaceutical composition thereof.
According to the fourth edition of the Diagnostic and Statistical Manual of Mental
Disorders (DSM-IV™) (1994, American Psychiatric Association. Washington. D.C.),
major depress disorders an. charnil one of more
Thus, the skilled artisan will recognize that the present invention is useful for the
treatment of a single episode and recurrent episodes of major depressive disorder.
In another preferred embodiment, the present invention provides a method for
treating anxiety, including generalized anxiety disorder, panic disorder, and obsessive-
compulsive disorder, comprising: administering to a patient in need thereof an effective
amount of a compound of Formula I or a pharmaceutical composition thereof.
At present, the fourth edition of the Diagnostic and Statistical Manual of Mental
Disorders (DSM-IV™) (1994, American Psychiatric Association, Washington, D.C.),

provides a diagnostic tool for anxiety and related disorders. These disorders include:
panic disorder with or without agoraphobia, agoraphobia without history of panic
disorder, specific phobia, social phobia or social anxiety disorder, obsessive-compulsive
disorder, post-traumatic stress disorder, acute stress disorder, generalized anxiety
disorder, anxiety disorder due to a general medical condition, substance-induced anxiety
disorder and anxiety disorder not otherwise specified. As used herein, the term "anxiety"
includes treatment of those anxiety disorders and related disorder as described in the
DSM-FV. The skilled artisan will recognize that there are alternative nomenclatures,
nosologies, and classification systems for neurological and psychiatric disorders,
particularly anxiety, and that these systems evolve with medical scientific progress. Thus,
the term "anxiety" is intended to include like disorders that are described in other
diagnostic sources.
Several preclinical laboratory animal models have been described for a number of
the disorders associated with an excess of tachykinins. One such in vivo assay, described
below, may be used to determine whether NK-1 receptor antagonists are CNS-penetrant.
Gerbil Foot-Tapping
The gerbil foot-tapping assay is well recognized in the art. For example,
see Rupniak et ah, Eur. J. Pharmacol. (1997) 326: 201-209.
Male Gerbils (Mongolian), weighing between 20-40 gm (Harlan Labs,
Indianapolis, Indiana) are used for the experiments. Animals are allowed to acclimate
prior io any testing.
An NK-1 receptor agonist, such as GR73632 (5-Aminovaleryl [Pro9, N-Me-
Substance- PC(10.254) He (Pennsula Labs) is dissolved acid fied saline (1ml acetir
acid m liter of 0.09% saline) to make a 1 mg/ml solution (corrected ior peptide content)
The stock solution is further diluted to 10 µg/ml in saline (0.9% normal saline), aliquoted
and kept frozen until use. The stock solution is further diluted to 3 pmol/5 pi in saline for
i.c.v. injections.
Test compounds are formulated in appropriate vehicle to a concentration of 1
ml/100 gm body weight. Compounds are dosed by oral eavage (p.o.) or subcutaneously
(s.c.) or intraperitoneally (i.p.) at pre-determined times prior to intracerebroventricular

(i.c.v.) challenge of agonist. For i.e.v. administration, test compound is co-injected with
agonist.
Free hand i.c.v. injection is performed by direct vertical insertion of a cuffed 27-
gauge needle with a Hamilton 50 µl syringe, to a depth of 4.5 mm below bregma. Light
anesthesia with isoflurane may be needed prior to the injection, but is not used routinely.
Following i.c.v. injection of agonist, animals are placed in a plexiglas observation
box, and hind foot tapping events are counted for 5 minutes. Data collection is
computerized.
Data are analyzed by AMOVA followed by Dunnett's test using JMP statistical
program (IBM platform). Data are expressed as number of events/5 minutes.
