FIELD OF THE INVENTION
This application claims benefit of provisional patent application serial number
60/404,239, filed on 16 August 2003, which is hereby incorporated by reference herein.
This invention relates to novel compounds and methods for use in treating an
intcgrin mediated disorder. More particularly, this, invention relates to piperidinyl
compounds that selective bind integrin receptors and methods for treating an integrin
mediated disorder.
BACKGROUND OF THE INVENTION
Integrins arc a family of transmembrane receptors, each of which is composed
of a pair of heterodimeric, noncovalently associated glycoproteins, designated as a and
ß chains. The a subunit contains heavy and light chains as part of its extracellular
domain, with 3-4 divalent-cation binding sites; the light chain also contains
transmembrane and intracellular domains. The ß-subunit contains a large extracellular
domain, as well as transmembrane and int'acellular domains. Integrins arc cell surface
receptors, which bind to extracellular matrix adhesive proteins such as fibrinogen,
libronectin, vitronectin and osteopontin. These transmembrane glycoproteins are
classified by the ß subunits. The ß3 class of integrin family has received the most
attention in recent drug discovery efforts (W.J. Hoekstra, Current Medicinal Chemistry,
1998, 5, 195), however, the ß5 class has also become a focus of attention. Some of the
disease states that have been associated with a strong ß3 and ß5 intcgrin component in
their etiologies are thrombosis (integrin a2bß3 also called GPIIb/IIIa); unstable angina
(GPIIb/IIIa); restenosis (GPIIb/IIIa and integrin av(33); arthritis, vascular disorders or
osteoporosis (avß3); tumor angiogenesis, multiple sclerosis, neurological disorders,
asthma, vascular injury or diabetic retinopathy (avß3 or avß5) and tumor metastasis
(avß3). See S.A. Mousa, et al, Emerging Therapeutic Targets, 2000, 4(2) 148-149:
and W.H. Miller, et al., Drug Discovery Today, 2000, 5(9), 397-40. Antibodies and/or
low-molecular weight compound antagonists of avß3 have shown efficacy against these
respective disease states in animal models (J. Samanen, Current Pharmaceutical
Design, 1997, 3 545-584) and thereby offer promise as therapeutic agents. Several
patents have described compounds that could interact with these integrins. For
example, United States Patents 5,919,792 B1, 6,211,191 Bl, and WO 01/96334 and
WO 01/23376 describe avß3 and (avß5 integrin receptor antagonists.
The present invention provides a new class of piperidinyl compounds, which
selective bind to (33, (35 or dual integrin receptors (e.g. avß3 and av(35) for the treatment
of a wide variety of integrin mediated disease states.

As used herein, the following underlined terms are intended to have the
following meanings:
The term "Ca-b" (where a and b are integers referring to a designated number of
carbon atoms) refers to an alkyl, alkenyl, alkynyl, alkoxy or cycloalkyl radical or to the
alkyl portion of a radical in which alkyl appears as the prefix root containing from a to
b carbon atoms inclusive. For example, C1-3 denotes a radical containing 1, 2 or 3
carbon atoms.
The term "alkyl" refers to an optionally substituted saturated or partially
unsaturated, branched, straight-chain or cyclic monovalent hydrocarbon radicals
derived by the removal of one hydrogen atom from a single carbon atom of an alkane
molecule, thus forming the point of attachment. The term "alkenyl" refers to an
optionally substituted partially unsaturated branched or straight-chain monovalent
hydrocarbon radical having at least one carbon-carbon double bond and derived by the
removal of one hydrogen atom from a single carbon atom of an alkene molecule, thus
forming the point of attachment. The radical may be in either the cis or trans
conformation about the double bond(s). The term "alkynyl" refers to an optionally
substituted partially unsaturated branched or straight-chain monovalent hydrocarbon
radical having at least one carbon-carbon triple bond and derived by the removal of one
hydrogen atom from a single carbon atom of an alkyne molecule, thus forming the point
of attachment. The term "alkoxy" refers to an optionally substituted saturated or
partially unsaturated, branched, straight-chain monovalent hydrocarbon radical derived
by the removal of the hydrogen atom from the single oxygen atom of an allcane, alkene
or alkyne molecule, thus forming the point of attachment. An alkyl alkenyl, alkynyl or
alkoxy radical is optionally substituted within the radical or on a terminal carbon atom
(for a chain) with that amount of substituents allowed by available saturated valences.
The term "-C1-8alkyl(Rx)" (where x is an integer referring to a designated
substitutent group) refers to an Rx substituent group which may be substituted within an
alykl chain, on a terminal carbon atom and may be similarly substituted on an alkenyl,
alkynyl or alkoxy radical with a designated amount of substituents where allowed by
available chemical bond valences. The term "-C1-8alkyl(Rx)" refers to an Rx substituent
group which may also be directly substituted on a pointof attachment without an alkyl
linking group (wherein Co is a placeholder for the Rx- substituent with a direct bond to
the point of attachment).
The term "cycloalkyl" refers to saturated or partially unsaturated cyclic
monovalent hydrocarbon radical consistent with the definitions of alkyl, alkanyl,
alkenyl and alkynyl. Specifically included within the definition of cycloalkyl are fused
polycyclic ring systems in which one or more rings are aromatic and one or more rings
are saturated or partially unsaturated (it being understood that the radical may also
occur on the aromatic ring). For example, the cycloalkyl groups are saturated or
partially unsaturated or monocyclic alkyl radicals of from 3-8 carbon atoms (derived
from a molecule such as cyclopropane, cyclobutane, cyclopentane, cyclohexane or
cycloheptane); saturated or partially unsaturated fused or benzofused cyclic alkyl
radicals of from 9 to 12 carbon atoms; or, saturated or partially unsaturated fused or
benzo fused tricyclic or polycyclic alkyl radicals of from 13 to 20 carbon atoms.
The term "heterocyclyl" refers to a saturated or partially unsaturated cyclic alkyl
radical in which one or more carbon atoms are independently replaced with the same or
different heteroatom. Specifically included within the definition of heterocyclyl are
fused polycyclic ring systems in which one or more rings are aromatic and one or more
rings are saturated or partially unsaturated (it being understood that the radical may also '
occur on the aromatic ring). Typical heteroatoms to replace the carbon atom(s) include,
but are not limited to, N, O, S and the like. For example, the heterocyclyl group is a
saturated or partially unsaturated five membered monocyclic alkyl ring of which at least
one member is replaced by a N, O or S atom and which optionally contains one
additional O atom replacing an additional member of the alkyl ring or one additional N
atom replacing a member of the alkyl ring; a saturated or partially unsaturated six
membered monocyclic alkyl ring of which one, two or three members of the alkyl ring
are replaced by a N atom and optionally one member of the alkyl ring is replaced by a O
or S atom or two members of the alkyl ring are replaced ,by O or S atoms; a saturated or
partially unsaturated 5-6 membered heterocylic ring as previously defined fused to a

or 10 membered bicyclic alkyl wherein at least one member of the ring is replaced by
N, O, or S atom and which optionally one or two additional members of the bicyclic
alkyl are replaced by N, O or S atoms; or, a saturated, partially unsaturated or
benzofused 11 to 20 membered polycyclic alkyl of which at least one member is
replaced by a N, O or S atom and which optionally one, two or three additional
members of the polycyclic alkyl are replaced by N atoms. Examples of saturated or
partially unsaturated heterocyclyl radicals include, but are not limited to, 2-pyrrolinyl,

tetrahydro-3-quinolinyl or dihydrobenzofuranyl.
The term "aryl" refers to a monovalent aromatic hydrocarbon radical derived by
the removal of one hydrogen atom from a single carbon atom of an aromatic ring
system, thus forming the point of attachment for the radical. For example, the aryl
group is derived from an unsaturated aromatic monocyclic ring system containing 5 to 6
carbon atoms (such as phenyl, derived from benzene); an unsaturated aromatic bicyclic
ring system containing 9 to 10 carbon atoms (such as naphthyl, derived from
naphthalene); or, an unsaturated aromatic tricyclic ring system containing 13 to 14
hydrogen carbon atoms (such as anthracenyl, derived from anthracene). The term
"aromatic ring system" refers to an unsaturated cyclic or polycyclic ring system having
an "aromatic" conjugated p electron system. Specifically excluded from the definition
of aryl are fused ring systems in which one or more rings are saturated or partially
unsaturated. Typical aryl groups include, but are not limited to, anthracenyl,
naphthalenyl, azulenyl, benzenyl and the like
The term "heteroaryl" refers to a monovalent heteroaromatic radical derived by
the removal of one hydrogen atom from a single atom of a heteroaromatic ring system,
thus forming the point of attachment for the radical. The term "heteroaromatic ring
system" refers to an aromatic ring system in which one or more carbon atoms are each
independently replaced with a heteroatom. Typical heteratoms to replace the carbon
atoms include, but are not limited to, N, O, S, and the like; Specifically excluded from
the definition of heteroaromatic ring system are fused ring systems in which one or
more rings are saturated or partially unsaturated. For example, the heteroaryl group is
derived from a heteroaromatic monocyclic ring system containing five members of
which at least one member is a N, O or S atom and which optionally contains one, two
or three additional N atoms; a heteroaromatic monocyclic ring system having six
members of which one, two or three members are an N atom; a heteroaromatic fused
bicyclic ring system having nine members of which at least one member is a N, O or S
atom and which optionally contains one, two or three additional N atoms; a
heteroaromatic fused bicyclic ring system having ten members of which one, two or
three members are a N atom; a heteroaromatic fused tricyclic ring system containing 13
or 14 members of which at least one member is a N, O or S atom and which optionally
contains one, two or three additional N atoms; or, a heteroaromatic fused polycyclic
ring system containing 15 to 20 members of which at least one member is a N, O or S
atom and which optionally contains one, two or three additional N atoms. Typical
heteroaryls include, but are not limited to, cinnolinyl, furanyl, imidazolyl, indazolyl,
indolyl, indolinyl, indolizinyl, isobenzofuranyl, isoquinolinyl, isothiazolyl, isoxazolyl,

quinolinyl, quinoxalinyl, tetrazole, thiadiazole, thiazole, thiophene, triazole and the
like.
The term "independently" means that when a group is substituted with more
than one substituent that the substituents may be the same or different. The term
"dependently" means that the substituents are specified in an indicated combination of
structure variables.
Under standard nomenclature rules used throughout this disclosure, the terminal
portion of the designated side chain is described first followed by the adjacent
functionality toward the point of attachment. Thus, for example, a "phenylC1-
6alkylamidoC1-6alkyl" substituent refers to a group of the formula:

A substituent's point of attachment may also be indicated by a dashed line to
indicate the point(s) of attachment, followed by the adjacent functionality and ending
with the terminal functionality such as, for example, __-(C1-6)alkyl-carbonyl-NH-(C1-
6)alkyl-phenyl.
It is intended that the definition of any substituent or variable at a particular
location in a molecule be independent of its definitions elsewhere in that molecule. It is
understood that substituents and substitution patterns on the compounds of this
invention can be selected by one of ordinary skill in the art to provide compounds that
are chemically stable and that can be readily synthesized by techniques known in the art
as well as those methods set forth herein.
Integrins are a widely expressed family of calcium or magnesium dependent a or
ß heterodimeric cell surface receptors, which bind to extracellular matrix adhesive
proteins such as fibrinogen, fibronectin. vitronectin and osteopontin. The integrin
receptors are transmembranc glycoproteins (GP's) known for their large extracellular
domains and are classified by at least 8 known ß subunits and 14 a subunits (S. A.
Mousa, et al., Emerging Theraupeutic Targets, 2000, 4, (2), 143-153).
For example, the ß1 subfamily has the largest number of integrins wherein the
various a subunits associate with various ß subunits: ß3, ß5, ß6 and ß8 (S. A. Mousa, et
al., Emerging Theraupeutic Targets, 2000, 4, (2), 144-147). Some of the disease states
that have a strong avß3, avß5 and aIIbß3 (also referred to as GPIIb/IIIa) integrin
component in their etiologies are unstable, angina, thromboembolic disorders or
atherosclerosis (GPIIb/IIIa); thrombosis or restenosis (GPIIb/IIIa or avß3); restenosis
(dual avß3/GPHb/IIIa); rheumatoid arthritis, vascular disorders or osteoporosis (avß3);
tumor angiogenesis, tumor metastasis, tumor growth, multiple sclerosis, neurological
disorders, asthma, vascular injury or diabetic retinopathy (avß3 or avß5); and,
angiogenesis (dual avß3/avß5) (S. A. Mousa, et al.. Emerging Theraupeutic Targets,
2000, 4, (2), 148-149; W. H. Miller, et al., Drug Discovery Today 2000, 5 (9), 397-407;
and, S. A. Mousa, et al., Exp. Opin. Ther. Patents?, 1999, 9 (9), 1237-1248). The ß3
subunit has received significant attention in recent drug discovery efforts. (W. J. Hoekstra,
Current Medicinal Chemistry 1998, 5, 195). Antibodies and/or low-molecular weight
compound antagonists of avp3 have shown efficacy in animal models (J. Samanen,
Current Pharmaceutical Design 1997, 3, 545) and, thereby, offer promise as medicinal
agents.
Integrin antagonists have typically been designed after the bioactive arginine-
glycine-aspartate (RGD) conformation of peptides derived from the primary ligand
vitronectin. The RGD motif is the general cell attachment sequence of many
extracellular matrix, blood and cell surface proteins, as half of the approximately 20
known integrins bind the RGD-containing adhesion ligands. To discover RGD
peptides with integrin selectivity, peptides with both restricted conformations and
alterations of flanking residues have been studied. In particular, the structural
requirements for interaction of the RGD sequence with GPIIb/IIIa and the inhibitory
potential of a series of nonpeptidic mimetics on platelet aggregation and interactions
with the extracellular matrix have been described (D. Varon, et al., Thromb.
Haemostasis, 1993, 70(6), 1030-1036). Iterative synthesis of cyclic and alicyclic
peptides and computer modelling have provided potent, selective agents as a platform
for nonpeptide av (as in avß3) integrin antagonist design.
Integrin antagonists have been implicated as useful for inhibiting bone
resorption (S.B. Rodan and G.A. Rodan, Integrin Function In Osteoclasts, Journal of
Endocrinology, 1997, 154: S47-S56). In vertebrates, bone resorption is mediated by the
action of cells known as osteoclasts, large multinucleated cells of up to about 400 mm
in diameter that resorb mineralized tissue, chiefly calcium carbonate and calcium
phosphate. Osteoclasts are actively motile cells that migrate along the surface of bone
and can bind to bone, secrete necessary acids and proteases, thereby causing the actual
resorption of mineralized tissue from the bone. More specifically, osteoclasts are
believed to exist in at least two physiological states, namely, the secretory state and the
migratory or motile state. In the secretory state, osteoclasts are flat, attach to the bone
matrix via a tight attachment zone (sealing zone), become highly polarized, form a
ruffled border and secrete lysosomal enzymes and protons to resorb bone. The
adhesion of osteoclasts to bone surfaces is an important initial step in bone resorption.
In the migratory or motile state, osteoclasts migrate across bone matrix and do not take
part in resorption until they again attach to bone.
Integrins are involved in osteoclast attachment, activation and migration. The
most abundant integrin receptor on osteoclasts (e.g., on rat, chicken, mouse and human
osteoclasts) is the avß3 integrin receptor, which is thought to interact in bone with
matrix proteins that contain the RGD sequence. Antibodies to avß3 block bone
resorption in vitro, indicating that this integrin plays a key role in the resorptive
process. There is increasing evidence to suggest that avß3 ligands can be used
effectively to inhibit osteoclast mediated bone resorption in vivo in mammals.
The current major bone diseases of public concern are osteoporosis,
hypercalcemia of malignancy, osteopenia due to bone metastases, periodontal disease,
hyperparathyroidism, periarticular erosions in rheumatoid arthritis, Paget's disease,
immobilization-induced osteopenia and glucocorticoid-induced osteoporosis. All of
these conditions are characterized by bone loss, resulting from an imbalance between
bone resorption, i.e. breakdown and bone formation, which continues throughout life at
the rate of about 14% per year on the average. However, the rate of bone turnover
differs from site to site; for example, it is higher in the trabecular bone of the vertebrae
and the alveolar bone in the jaws than in the cortices of the long bones. The potential
for bone loss is directly related to turnover and can amount to over 5% per year in
vertebrae immediately following menopause, a condition that leads to increased fracture
risk.
In the United States, there are currently about 20 million people with detectable
fractures of the vertebrae due to osteoporosis. In addition, there are about 250,000 hip
fractures per year attributed to osteoporosis. This clinical situation is associated with a
12% mortality rate within the first two years, while 30% of the patients require nursing
home care after the fracture. Individuals suffering from all the conditions listed above
would benefit from treatment with agents that inhibit bone resorption.
Additionally, avß3 ligands have been found to be useful in treating and or
inhibiting restenosis (i.e. recurrence of stenosis after corrective surgery on the heart
valve), atherosclerosis, diabetic retinopathy, macular degeneration and angiogencsis
(i.e. formation of new blood vessels) and inhibiting viral disease.
Moreover, it has been postulated that the growth of tumors depends on an
adequate blood supply, which in turn is dependent on the growth of new vessels into the
tumor; thus, inhibition of angiogencsis can cause tumor regression in animal models
(Harrison's Principles of Internal Medicine, 1991, 12th ed.). Therefore, avß3
antagonists, which inhibit angiogenesis can be useful in the treatment of cancer by
inhibiting tumor growth (Brooks et al., Cell, 1994, 79, 1157-1164). Evidence has also
been presented suggesting that angiogenesis is a central factor in the initiation and
persistence of arthritic disease and that the vascular integrin avß3 may be a preferred
target in inflammatory arthritis. Therefore, avß3 antagonists that inhibit angiogenesis
may represent a novel therapeutic approach to the treatment of arthritic disease, such as
rheumatoid arthritis (C.M. Storgard, et al., Decreased Angiogenesis and Arthritic
Disease in Rabbits Treated With an avp3 Antagonist, J. Clin. Invest, 1999, 103, 47-
54).
Inhibition of the avß5 integrin receptor can also prevent neovascularization. A
monoclonal antibody for avß5 has been shown to inhibit VEGF-induced angiogenesis
in rabbit cornea and the chick chorioallantoic membrane model (M.C. Friedlander, et
al., Science, 1995, 270, 1500-1502). Thus, avp5 antagonists are useful for treating and
preventing macular degeneration, diabetic retinopathy, cancer and metastatic tumor
growth.
Inhibition of av integrin receptors can also prevent angiogenesis and
inflammation by acting as antagonists of other ß subunits, such as avß6 and avß8
(Melpo Christofidou-Solomidou, et al., Expression and Function of Endothelial Cell on
Integrin Receptors in Wound-Induced Human Angiogenesis in Human Skin/SCID 25
Mice Chimeras, American Journal of Pathology, 1997, 151, 975-83; and, Xiao-Zhu
Huang, et al., Inactivation of the Integrin ß6 Subunit Gene Reveals a Role of Epithelial
Integrins in Regulating Inflamnation in the Lungs and Skin, Journal of Cell Biology,
1996, 133,921-28).
An antagonist to the av integrin can act to inhibit or minimize adhesions that
result from either wounding or surgical adhesions. Post-surgical adhesions result as an
anomaly of the wound healing process. Cell adhesion and the migration of fibroblasts
are major players in this process. Trauma caused by the wounding, a surgical
procedure, normal tissue manipulation in surgery, or bleeding during a surgical
procedure can act to disrupt the peritoneum and expose the underlying stroma leading
to the release of inflammatory mediators and an increase in capillary permeability.
Inflammatory cells are subsequently liberated and the formation of a fibrin clot ensues.
Adhesions are formed and intensify as fibroblasts and inflammatory cells continue to
infiltrate this extracellular matrix rich in fibrin. The extracellular matrix is composed
of adhesive proteins which act as ligands for the av integrin. To inhibit post-surgical
adhesion development, application of an av antagonist could be parenteral,
subcutaneous, intravenous, oral, topical or transdermal. The av integrin antagonist can
be administered before, during or after a surgical procedure. When administered during
a surgical procedure the antagonists can be administered by aerosol, in a pad, gel, film,
sponge, solution, suspension or similar suitable pharmaceutically acceptable earner to
the area in which the surgery is performed.

prodrugs thereof. Each anti-tumor agent is administered in a therapeutically effective
amount, which varies based on the agent used, the type of malignancy to be treated or
ameliorated and other conditions according to methods well known in the art.
As will be understood by those skilled in the art, the appropriate doses of
chemotherapeutic agents will be generally around those already employed in clinical
therapies wherein the chemotherapeutics arc administered alone or in combination with
other chemotherapeutics. By way of example only, agents such as cisplatin and other
DNA alkylating are used widely to treat cancer. The efficacious dose of cisplatin used
in clinical applications is about 20 mg/m2 for 5 days every three weeks for a total of three Courses. Cisplatin is not absorbed orally and must therefore be delivered via
injection intravenously, subcutaneously, intratumorally or intrapcritoneally. Further
useful agents include compounds that interfere with DNA replication, mitosis and
chromosomal segregation. Such chcmotherapeutic agents include adriamycin
(doxorubicin), etoposide, verapamil or podophyllotoxin and the like and are widely
used in clinical settings for tumor treatment. These compounds are administered
through bolus injections intravenously at doses ranging from about 25 to about 75
mg/m2 at 21 day intervals (for adriamycin) or from about 35 to about 50 mg/m2 (for
etoposide) intravenously or at double the intravenous dose orally. Agents that disrupt
the synthesis and fidelity of polynucleotide precursors such as 5-fluorouracil (5-FU) are
preferentially used to target tumors. Although quite toxic, 5-FU is commonly used via
intravenous administration with doses ranging from about 3 to about 15 mg/kg/day.
Another aspect of the present invention includes a method for administering a
compound of the present invention in combination with radiation therapy. As used
herein, "radiation therapy" refers to a therapy that comprises exposing the subject in
need thereof to radiation. Such therapy is known to those skilled in the art. The
appropriate scheme of radiation therapy will he similar to those already employed in
clinical therapies wherein the radiation therapy is used alone or in combination with
other chemotherapeutics.
An aspect of the present invention includes a method for administering a
compound of the present invention in combination, with a gene therapy or for use of a
compound of the present invention as a gene therapy means. The term "gene therapy"
refers to a therapy targeting angiogenic endothelial cells or tumor tissue during tumor
development. Gene therapy strategies include the restoration of defective cancer-
inhibitory genes, cell transduction or transfection with antisense DNA (corresponding
to genes coding for growth factors and their receptors) and the use of "suicide genes."
The term "gene therapy means" refers to the use of a targeting vector comprising a
combination of a cationic nanoparticlc coupled to an av-targeting ligand to influence
blood vessel biology; whereby genes are selectively delivered to angiogenic blood
vessels (as described in Hood, J.D., et al. Tumor Regression by Targeted Gene Delivery
to the Neovasculature, Science, 2002, 28 June, 296, 2404-2407).
Another aspect of the present invention includes a method for treating or
ameliorating an av integrin mediated neoplasin in a subject in need thereof comprising
administering to the subject an effective amount of a gene therapy combination product
comprising a compound of Formula (1) or composition thereof and a gene therapeutic
agent; wherein the product is delivered or "seeded" directly to a neoplasm or the
microenvironment thereof by antagonizing the av integrin receptors of the neoplasm or
microenvironment thereof.
The term "delivered or 'seeded' directly to a neoplasm" includes using a
compound of Formula (I) or composition thereof as a gene therapy means whereby the
compound or composition thereof functions as a targeting agent which directs the
conjugate to its intended site of action (i.e., to neoplastic vascular endothelial cells or to
tumor cells). Because of the specific interaction of the av integrin inhibitor as a
targeting agent and its corresponding av integrin receptor site, a compound of this
invention can be administered with high local concentrations at or near a targeted av
integrin receptor, or subtype thereof, thus treating the av integrin mediated disorder
more effectively.
Another aspect of the present invention includes a method for administering a
compound of the present invention in combination with an immunotherapy. As used
herein, "immunotherapy" refers to a therapy targeted to a particular protein involved in
tumor development via antibodies specific to such protein. For example, monoclonal
antibodies against vascular endothelial growth factor have been used in treating
cancers.
An aspect of the present invention includes a method for tumor imaging in a
subject in need thereof comprising advantageously coadministering to the subject an
effective amount of a compound of Formula (I) or composition thereof; wherein the
compound or composition thereof is conjugated with and delivers a non-invasive tumor
imaging agent to a tumor or to the microenvironment around the tumor.

by a conjugation means known to those skilled in the art; wherein the compound or
composition thereof acts as a targeting agent for antagonizing the av integrin receptors
of a neoplasm or the microenvironment thereof; and, wherein the conjugation means
facilitates and selectively delivers the imaging agent to the neoplasm or the
microenvironment thereof (as described in PCT Application WO00/35887,
WO00/35492, WO00/35488 or WO99/58162). The term "imaging agent," including
but not limited to Technetium99, refers to imaging agents known to those skilled in the
art. The term "conjugation means," including but not limited to appending a compound
to a linking group followed by conjugation with an imaging agent chelating group,
refers to means known to those skilled in the art.
Coronary angioplasty is a highly effective procedure used to reduce the severity
of coronary occlusion; however, its long-term success is limited by a high rate of
restenosis. Vascular smooth muscle cell activation, migration and proliferation is
largely responsible for restenosis following angioplasty (Ross, R., Nature, 1993, 362,
801-809).
An aspect of the present invention includes a method for use of av integrin
inhibitor compound of Formula (I) or composition thereof for treating or ameliorating
arterial and venous restenosis; wherein the compound is impregnated on the surface of
a therapeutic device. The term "therapeutic device" refers to, and is not limited to, an
angioplasty balloon, arterial stent, venous stent, suture, artificial joint, implanted
prosthesis or other like medical devices, thus targeting drug delivery to a neoplasm.
An aspect of the present invention includes a composition comprising a
compound of Formula (I), or pharmaceutically acceptable salt thereof, in association
with a pharmaceutically acceptable carrier. Compositions contemplated within this
invention can be prepared according to conventional pharmaceutical techniques. A
pharmaceutically acceptable carrier may also (but need not necessarily) be used in the
composition of the invention.
The term "pharmaceutically acceptable" refers to molecular entities and
compositions that do not produce an adverse, allergic or other untoward reaction when
administered to an animal, or a human, as appropriate. Veterinary uses are equally
included within the invention and "pharmaceutically acceptable" formulations include
formulations for both clinical and/or veterinary use.
The composition may take a wide variety of forms depending on the form of
preparation desired for administration including, but not limited to, intravenous (both
bolus and infusion), oral, nasal, transdermal, topical with or without occlusion, and
injection intraperitoneally, subcutaneously, intramuscularly, intratumorally or
parenterally, all using forms well known to those of ordinary skill in the pharmaceutical
arts. The composition may comprise a dosage unit such as a tablet, pill, capsule,
powder, granule, sterile parenteral solution or suspension, metered aerosol or liquid
spray, drop, ampoule, auto-injector device or suppository; for administration orally,
parenterally, intranasally, sublingually or rectally or by inhalation or insufflation.
Compositions suitable for oral administration include solid forms such as pills, tablets,
caplets, capsules (each including immediate release, timed release and sustained release

formulations), granules and powders; and, liquid forms such as solutions, syrups,
elixirs, emulsions and suspensions. Forms useful for parenteral administration include
sterile solutions, emulsions and suspensions. Alternatively, the composition may be
presented in a form suitable for once-weekly or once-monthly administration; for
example, an insoluble salt of the active compound, such as the decanoate salt, may be
adapted to provide a depot preparation for intramuscular, injection, In preparing the
compositions in oral dosage form, one or more of the usual pharmaceutical carriers may
be employed, including necessary and inert pharmaceutical excipients, such as water,
glycols, oils, alcohols, flavoring agents, preservatives, coloring agents, syrup and the
like; in the case of oral liquid preparations, carriers such as starches, sugars, diluents,
granulating agents, lubricants, binders, disintegrating agents and the like may be
employed.
The dosage unit (tablet, capsule, powder, injection, suppository, measured liquid
dosage and the like) containing the pharmaceutical compositions herein will contain an
amount of the active ingredient necessary to deliver a therapeutically effective amount
as described above. The composition may contain from about 0.001 mg to about 5000
mg of the active compound or prodrug thereof and may be constituted into any form
suitable for the mode of administration selected for a subject in need.
An aspect of the present invention contemplates a therapeutically effective
amount in a range of from about 0.001 mg to 1000 mg/kg of body weight per day.
Another aspect of the present invention includes a range of from about 0.001 to about
500 mg/kg of body weight per day. A further aspect of the present invention includes a
range of from about 0.001 to about 300 mg/kg of body weight per day. The compounds
may be administered according to a dosage regimen of from about 1 to about 5 times per
day and still more preferably 1, 2 or 3 times a day.
For oral administration, the compositions are preferably provided in the form of
tablets containing, 0.01,0.05, 0.1, 0.5, 1.0, 2.5, 5.0, 10.0, 15.0, 25.0, 50.0, 100, 150, 200,
250 and 500 milligrams of the active ingredient for the. symptomatic adjustment of the
dosage to the patient to be treated. Optimal dosages to be administered may be readily
determined by those skilled in the art and will vary depending factors associated with
the particular patient being treated (age, weight, diet and time of administration), the
i
severity of the condition being treated,, the compound being employed, the mode of
administration and the strength of the preparation., The use of either daily administration or post-periodic dosing may be employed.
For preparing solid compositions such as tablets, the principal active ingredient
is mixed with a pharmaceutical carrier, e.g. conventional tableting ingredients such as
corn starch, lactose, sucrose, sorbitol, talc, stearic acid, magnesium stearatc, dicalcium
phosphate or gums and other pharmaceutical diluents, e.g. water, to form a solid
preformulation composition containing a homogeneous mixture of a compound of the
present invention, or a pharmaceutically acceptable salt thereof. When referring to
these preformulation compositions as homogeneous, it is meant that the active
ingredient is dispersed evenly throughout the composition so that the composition may
be readily subdivided into equally effective dosage forms such as tablets, pills and
capsules. This solid preformulation composition is then subdivided into unit dosage
forms of the type described above containing from 0.001 to about 5000 mg of the active
ingredient of the present invention. The tablets or pills of the composition can be
coated or otherwise compounded to provide a dosage form affording the advantage of
prolonged action. For example, the tablet or pill can comprise an inner dosage and an
outer dosage component, the latter being in the form of an envelope over the former.
The two components can be separated by an enteric layer that serves to resist
disintegration in the stomach and permits the inner component to pass intact into the
duodenum or to be delayed in release. A variety of material can be used for such
enteric layers or coatings, such materials including a number of polymeric acids with
such materials as shellac, acetyl alcohol and cellulose acetate.
For oral administration in the form of a tablet or capsule, the active drug
component can be optionally combined with an oral, non-toxic pharmaceutically
acceptable inert carrier such as ethanol, glycerol, water and the like. Moreover, when
desired or necessary, suitable binders; lubricants, disintegrating agents and coloring
agents can also be incorporated into the mixture. Suitable binders include, without
limitation, starch, gelatin, natural sugars such as glucose or beta-lactose, corn sweeteners,
natural and synthetic gums such as acacia, tragacanth or sodium oleate, sodium stearate,
magnesium stearate, sodium benzoate, sodium acetate, sodium chloride and the like.
Disintegrators include, without limitation, starch, methyl cellulose, agar, bentonite,
xanthan gum and the like.
The liquid forms in which the compound of formula (I) may be incorporated for
administration orally or by injection include, aqueous solutions, suitably flavored
syrups, aqueous or oil suspensions and flavored emulsions with edible oils such as
cottonseed oil, sesame oil, coconut oil or peanut oil, as well as elixirs and similar
pharmaceutical vehicles. Suitable dispersing or suspending agents for aqueous
suspensions, include synthetic and natural gums such as tragacanth, acacia, alginate,
dextran, sodium carboxymethylcellulose, methylcellulose, polyvinyl-pyrrolidonc or
gelatin. The liquid forms in suitably flavored suspending or dispersing agents may also
include the synthetic and natural gums, for example, tragacanth, acacia, methyl-cellulose
and the like. For parenteral administration, sterile suspensions and solutions are desired.
Isotonic preparations that generally contain suitable preservatives arc employed when
intravenous administration is desired.
As is also known in the art, the compounds may alternatively be administered
parenterally via injection of a formulation consisting of the active ingredient dissolved
in an inert liquid carrier. The injectable formulation can include the active ingredient
mixed with an appropriate inert liquid carrier. Acceptable liquid carriers include
vegetable oils such as peanut oil, cottonseed oil, sesame oil and the like, as well as
organic solvents such as solketal, glycerol and the like. As an alternative, aqueous
parenteral formulations may also be used. For example, acceptable aqueous solvents
include water, Ringer's solution and an isotonic aqueous saline solution. Further, a
sterile non-volatile oil can usually be employed as a solvent or suspending agent in the
aqueous formulation. The formulations are prepared by dissolving or suspending the
active ingredient in the liquid carrier such that the final formulation contains from
0.005 to 10% by weight of the active ingredient. Other additives including a
preservative, an isotonizer, a solubilizer, a stabilizer and a pain-soothing agent may
adequately be employed.
Advantageously, compounds of Formula (I) may be administered in a single daily
dose, or the total daily dosage may be administered in divided doses of two, three or four
times daily. Furthermore, compounds of the present invention can be administered in
intranasal' form via topical use of suitable intranasal vehicles, or via transdermal routes,
using those forms of transdermal skin patches well known to those of ordinary skill in
that art. To be administered in the form of a transdermal delivery system, the dosage
administration will, of course, be continuous rather than intermittent throughout the
dosage regimen.
Because of their ease of administration, tablets and capsules represent ah
advantageous oral dosage unit form, wherein solid pharmaceutical carriers are
employed. If desired, tablets may be sugarcoated or enteric-coated by standard
techniques. If desired, tablets may be sugar coated or enteric coated by standard
techniques. For parcnterals, the carrier will usually comprise sterile water, though other
ingredients, for example, for purposes such as aiding solubility or for preservation, may
be included. Injectable suspensions may also be prepared, in which case appropriate
liquid carriers, suspending agents and the like may be employed.
The compositions of the present invention also include a composition for slow
release of the compound of the invention. The composition includes a slow release
carrier (typically, a polymeric carrier) and a compound of the invention. In preparation
for slow release, a slow release carrier, typically a polymeric carrier and a compound of
the invention are first dissolved or dispersed in an organic solvent. The obtained
organic solution is then added into an aqueous solution to obtain an oil-in-water-type
emulsion. Preferably, the aqueous solution includes surface-active agent(s).
Subsequently, the organic solvent is evaporated from the oil-in-water-type emulsion to
obtain a colloidal suspension of particles containing the slow release carrier and the
compound of the invention. Slow release biodegradable carriers are also well known in
the art. These are materials that may form particles that capture therein an active
compound(s) and slowly degrade/dissolve under a suitable environment (e.g., aqueous,
acidic, basic, etc) and thereby degrade/dissolve in body fluids and release the active
compound(s) therein. The particles are preferably nanoparticles (i.e., in the range of
about 1 to 500 nm in diameter, preferably about 50-200 nm in diameter and most
preferably about 100 nm in diameter).
The present invention also provides methods to prepare the pharmaceutical
compositions of this invention. A compound of Formula (I) as the active ingredient is
intimately admixed with a pharmaceutical carrier according to conventional
pharmaceutical compounding techniques, which carrier may take a wide variety of
forms depending on the form of preparation desired for administration. In preparing the
compositions in oral dosage form, any of the usual pharmaceutical media may be
employed. For solid oral dosage forms, suitable carriers and additives include starches,
sugars, diluents, granulating agents, lubricants, binders, disintegrating agents and the
like. For liquid oral preparations, suitable carriers and additives include water, glycols,
oils, alcohols, flavoring agents, preservatives, coloring agents and the like.
Additionally, liquid forms of the active drug component can be combined in suitably
flavored suspending or dispersing agents such as the synthetic and natural gums,
including for example, tragacanth, acacia, methyl-cellulose and the like. Other
dispersing agents that may be employed include glycerin and the like.
An antibody targeting agent includes antibodies or antigen-binding fragments
thereof, that bind to a targetable or accessible component of a tumor cell, tumor
vasculature or tumor stroma. The "targetable or accessible component" of a tumor cell,
tumor vasculature or tumor stroma, is preferably a surface-expressed, surface-accessible
or surface-localized component. The antibody targeting agents also include antibodies
or antigen-binding fragments thereof, that bind to an intracellular component that is
released from a necrotic tumor cell. Preferably such antibodies are monoclonal
antibodies or antigen-binding fragments thereof that bind to insoluble intracellular
antigen(s) present in cells that may be induced to be permeable or in cell ghosts of
substantially all tumor or normal cells, but are not present or accessible on the exterior
of normal living cells of a mammal.
As used herein, the term "antibody" is intended to refer broadly to any
immunologic binding agent such as IgG, IgM, IgA, IgE, F(ab')2, a univalent fragment
such as Fab', Fab, Dab, as well as engineered antibodies such as recombinant
antibodies, humanized antibodies, bispecific antibodies and the like. The antibody can
be either the polyclonal or the monoclonal, although a monoclonal antibody is
preferred. There is a very broad array of antibodies known in the art that have
immunological specificity for the cell surface of virtually any solid tumor type (see a
Summary Table on monoclonal antibodies for solid tumors in U.S. patent 5,855,866,
Thorpe, et al). Methods are known to those skilled in the art to produce and isolate
antibodies to be used as targeting agents against tumors (U.S. patent 5,855,866,
Thorpe); and, U.S. patent 6,342,219 (Thorpe)).
Non-antibody targeting agents include growth factors that bind specifically to
the tumor vasculature and other targeting components such as annexins and related
ligands. In addition, a variety of other organic molecules can also be used as targeting
agents for tumors, examples are hyaluronan oligosaccharides which specifically
recognize Hyaluronan-binding protein, a cell surface protein expressed during tumor
cell and endothelial cell migration and during capillary-like tubule formation (U.S.
Patent 5,902,795 (Toole, et al.)) and polyanionic compounds, particularly polysulphated
or polysulphonated compounds such as N- and O-sulfated polyanionic polysaccharides,
polystyrene sulfonate and other polyanionic compounds (as described in U.S. Patent
5,762,918 (Thorpe) which selectively bind to vascular endothelial cells.
Techniques for conjugating a therapeutic moiety to antibodies are well known
(Amon, et al., Monoclonal Antibodies For Immunotargeting Of Drugs In Cancer
Therapy, Monoclonal Antibodies And Cancer Therapy, Reisfeld, et al. (eds,), pp. 243-
56 (Alan R. Liss, Inc. 1985); Hellstrom, et al., Antibodies For Drug Delivery,
Controlled Drug Delivery (2nd Ed.), Robinson, et al. (eds.), pp. 623-53 (Marcel
Dekker, Inc. 1987); Thorpe, Antibody Carriers Of Cytotoxic Agents In Cancer Therapy: A Review, Monoclonal Antibodies '84: Biological And Clinical Applications, Pinchera,
et al. (eds.), pp. 475-506 (1985). Similar technique's can also be applied to attach
compounds of the invention to non-antibody targeting agents. Those skilled in the art
will know or be able to select methods in the art for forming conjugates with non-
antibody targeting agents, such as oligopeptides, polysaccharides or other polyanionic
compounds.
Although any linking moiety that is reasonably stable in blood can be used to
link the compound of the invention to the targeting agen,t, those with biologically-
releasable bonds and/or selectively cleavable spacers or linkers are preferred.
"Biologically-releasable bonds" and "selectively cleavable spacers or linkers" refers to
those linking moieties which have reasonable stability in the circulation and are
releasable, cleavable or hydrolyzable only or preferentially under certain conditions,
(i.e., within a certain environment or in contact with a particular agent). Such bonds
include, for example, disulfide and trisulfide bonds and acid-labile bonds (as described
in U.S. Patent 5,474,765 and 5,762,918) and enzyme-sensitive bonds, including peptide
bonds, esters, amides, phosphodiesters and glycosides (as described in U.S. Patent
5,474,765 and 5,762,918). Such selective-release design features facilitate sustained
release of the compounds from the conjugates at the intended target site.
The therapeutically effective amount of a compound of the invention conjugated
to a targeting agent depends on the individual, the disease type, the disease state, the
method of administration and other clinical variables. The effective amount is readily
determinable using data from an animal model. Experimental animals bearing solid
tumors are frequently used to optimize appropriate therapeutically effective amounts
prior to translating to a clinical environment. Such models are known to be very
reliable in predicting effective anti-cancer strategies. For example, mice bearing solid
tumors are widely used in pre-clinical testing to determine working ranges of
therapeutic agents that give beneficial anti-tumor effects with minimal toxicity.
The present invention further provides a composition that comprises an
effective amount of the compound of the invention conjugated to a targeting agent and
a pharmaceutically acceptable carrier. When proteins such as antibodies or growth
factors, or polysaccharides are used as targeting agents, they are preferably administered
in the form of injectable compositions. The injectable antibody solution will be
administered into a vein, artery or into the spinal fluid over the course of from about 2
minutes to about 45 minutes, preferably from about 10 to about 20 minutes. In certain
cases, intradermal and intracavitary administration are advantageous for tumors
restricted to areas close to particular regions of the|Skin and/or to particular body
cavities. In addition, intrathecal administrations may be used for tumors located in the
brain.
Another aspect of the present invention includes a method for treating or
disorders related to av integrin expression (in particular, restenosis, intimal hyperplasia
or inflammation in vessel walls) in a subject in need thereof comprising administering
to the subject by controlled delivery a therapeutically effective amount of a compound
of Formula (I) or composition thereof coated onto an intraluminal medical device (in
particular, a balloon-catheter or stent). Such devices are useful to prevent the
occurrence of restenosis by inhibiting av integrin activity and thus preventing
hyperproliferation of the endothelium.
The term "intraluminal medical device" refers to any delivery device, such as
intravascular drug delivery catheters, wires, pharmacological stents and endoluminal
paving. The scope of the present invention includes delivery devices comprising an
arterial or venous stent having a coating or sheath which elutes or releases a
therapeutically effective amount of an instant compound. The term "controlled
delivery" refers to the release of active ingredient in a site-directed and time dependent
manner. Alternatively, the delivery system for such a device may comprise a local
infusion catheter that delivers the compound at a variably controlled rate.
The term "stent" refers to any device capable of being delivered by a catheter.
A stent is routinely used to prevent vascular closure due to physical anomalies such as
unwanted inward growth of vascular tissue due to surgical trauma. A stent often has a
tubular, expanding lattice-type structure appropriate to be left inside the lumen of a duct
to relieve an obstruction. The stent has a lumen wall-contacting surface and a lumen-
exposed surface. The lumen-wall contacting surface is the outside surface of the tube
and the lumen-exposed surface is the inner surface of the tube. The stent material may
be a polymeric, metallic or a combination polymeric-metallic material and can be
optionally biodegradable.
Commonly, a stent is inserted into the lumen in a non-expanded form and are
then expanded autonomously, or with the aid of a second device in situ. A typical
method of expansion occurs thr.ough the use of a catheter-mounted angioplastry balloon
which is inflated within the stenosed vessel or body passageway in order to shear and
disrupt the obstructions associated with the wall components of the vessel and to obtain
an enlarged lumen. Self-expanding stents as described in pending U.S. Patent
application 2002/0016625 Al (Falotico, et al.) may also be utilized. The combination
of a stent with drugs, agents or compounds which prevent inflammation and
proliferation may provide the most efficacious treatment for post-angioplastry
restenosis.
Compounds of the present invention can be incorporated into or affixed to the
stent in a number of ways. A solution of the compound of the invention and a
biocompatiblc material or polymer may be incorporated into or onto a stent in a number
of ways. For example, a solution of an instant compound may be sprayed onto the stent
or the stent may be dipped into the solution and, in each case, allowed to dry. Another
coating method electrically charges a solution of an instant compound to one polarity
and charges the stent to the opposite polarity. In this manner, the solution and stent will
be attracted to one another. Another method coats the stent with a solution of an instant
compound using supercritical temperature and pressure conditions. Coating the stent
using supercritical conditions reduces waste and allows more control over the thickness
of the coat may be achieved. The compound is usually only affixed to the outer surface
of the stent (the surface which makes contact with the tissue), but for some compounds,
the entire stent may be coated.
A combination product comprising a therapeutically effective amount of an
instant compound coated on the stent and on or in a layer or layers of a polymer coating
wherein the polymer coating controls the release rate of the drug may be used when the
effectiveness of the drug is affected. Accordingly., the compound may be released from
the stent over a period of at least about 6 months; in another aspect, over a period of
about 3 days to about 6 months; and, in another aspect over a period of about 7 to about
i
30 days. Any number of non-erodible,, biocompatible polymeric materials may be used
for the polymer coating layer or layers in conjunctipn with the compound of the
invention.
In one illustration, the compound is directly incorporated into a polymeric
matrix, such as the polymer polypyrrole and subsequently coated onto the outer surface
of the stent. Essentially, the compound elutes from the matrix by diffusion through the
polymer molecules. Stents and methods for coating drugs on stents are discussed in
detail in PCT application WO 96/32907. In another aspect, the stent is first coated with
as a base layer comprising a solution of the compound, ethylene-co-vinylacetate and
polybutylmethacrylate. The stent is then further coated with an outer layer comprising
polybutylmethacrylate. The outlayer acts as a diffusion barrier to prevent the
compound from eluting too quickly and entering the surrounding tissues. The thickness
of the outer layer or topcoat determines the rate at which the compound elutes from the
matrix. Stents and methods for coating are discussed in detail in pending U.S. Patent
application 2002/0016625 Al.
It is important to note that different polymers may be utilized for different
stents. For example, the above-described ethylene-co-vinylacetate and
polybutylmethacrylate matrix works well with stainless steel stents. Other polymers
may be utilized more effectively with stents formed from other materials, including
materials that exhibit superelastic properties such as alloys of nickel and titanium or
shape-retentive polymeric materials that "remember" and return to their original shape
upon activation at body temperature.
Methods for introducing a stent into a lumen of a body are well known. In an
aspect of this invention, a compound-coated stent is introduced using a catheter. As
will be appreciated by those of ordinary skill in the art, methods will vary slightly based
on the location of stent implantation. For coronary'stent implantation,1 the balloon
catheter bearing the stent is inserted into the coronary artery and the stent is positioned
at the desired site. The balloon is inflated, expanding the stent. As the stent expands,
the stent contacts the lumen wall. Once the stent is positioned, the balloon is deflated
and removed. The stent remains in place with the lumen-contacting surface bearing the
compound directly contacting the lumen wall surface. Stent implantation may be
accompanied by anticoagulation therapy as needed.
Optimum conditions for delivery of the compounds for use in the stent of the
invention may vary with the different local delivery systems used, as well as the
properties and concentrations of the compounds used. Conditions that may be
optimized include, for example, the concentrations of the compounds, the delivery
volume, the delivery rate, the depth of penetration of the vessel wall, the proximal
inflation pressure, the amount and size of perforations and the fit of the drug delivery
catheter balloon. Conditions may be optimized for inhibition of smooth muscle cell
proliferation at the site of injury such that significant arterial blockage due to restenosis
does not occur, as measured, for example, by the proliferative ability of the smooth
muscle cells or by changes in the vascular resistance or lumen diameter. Optimum
conditions can be determined based on data from animal model studies using routine
computational methods.
The compounds of the present invention can also be administered in the form of
liposome delivery systems, such as small unilamellar vesicles, large unilamellar
vesicles and multilamellar vesicles. Liposomes containing delivery systems as well
known in the art are formed from a variety of phospholipids, such as cholesterol,
stearylamine or phosphatidylcholines.

with the general synthetic methods described below and are illustrated more particularly
in the schemes that follow. Since the schemes are illustrations whereby intermediate

not be construed as being limited by the chemical reactions and conditions expressed.
Additional representative compounds and stereoisomers, racemic mixtures,
diastereomers and cnantiomers thereof can be synthesized using the intermediates

reagents known to those skilled in the art. All such compounds, stereoisomers, racemic
mixtures, diastereomers and cnantiomers thereof arc intended to be encompassed within
the scope of the present invention. The preparation of the various starting materials
used in the schemes is well within the skill of persons versed in the art.

Scheme A describes a method for preparing a target compound of Formula (I) (wherein
R, and W are as previously defined within the scope of the invention. Removal of the
Boc-protective group from a Ra substituted (wherein Ra is C1-4alkyl) Compound Al
was accomplished under acidic conditions (by using an acid such as an acidic mixture
of TFA and DCM or an inorganic acid in an appropriate solvent such as dioxanc) and
resulted in formation of a piperidine Compound A2 Coupling of the piperidine
Compound A2 with a carboxylic acid Compound A3 under standard coupling
conditions (by using a mixture of coupling agents such as HOBt/EDC, HOBT/HBTU
or isobutyl chloroformate in the presence of a suitable base such as NMM or DIEA)
afforded the ester Compound A4. Hydrolysis of the ester Compound A4 under acidic
or basic conditions yielded a target compound Formula (1). The individual isomcrs of
Formula (I) can be achieved through the chiral separation of intermediate Al - A4, and
elaboration of the chiral intermediates to compounds of Formula (1).

halogen or a mesylate or tosylate under standard coupling conditions (by using a
mixture of coupling agents such as HOBt/EDC, HOBT/HBTU or isobutyl
chloroformatc in the presence of a suitable base such as NMM or DIEA) resulted in the
formation of Compound B2. Reaction of Compound B2 with a substituted aminc
Compound B3 in the presence of an appropriate base such as LiHMDS, NaHMDS or
LDA resulted in the formation of Compound B4. Treatment of Compound B4 with
aqueous hydrochloric acid resulted in hydrolysis of the ester to yield a target compound

Compound C5 upon reaction with an appropriately substituted phosphorane or
phosphonate Compound CA in the presence of a base such as LiHMDS, NaHMDS, LDA or the like. Conversion of Compound CS to Compound Al was accomplished

about 50 psi was used) in the presence of an appropriate catalyst such as 5 or 10%
palladium on carbon.
Scheme C
Scheme D

which (CH2)q is (CH2)2-3- Reaction of an amide Compound C2 with an appropriate
reducing agent such as lithium aluminum hydride or the like resulted in the formation
of an aldehyde Compound Dl. Condensation of an in situ generated acetylide
i
Compound D2 with the aldehyde Compound Dl at a low temperature resulted in
formation of a propargylic alcohol Compound D3. The alkyne Compound D3 was
selectively reduced to a cis-olefin Compound D4 under hydrogenolysis conditions using
Lindlar's catalyst in pyridine. Condensation of the allylic alcohol Compound D4 with
an Ra substituted 3-chloro-3-oxopropionate Compound D5 in the presence of a base
such as TEA, DIEA or the like resulted in the formation of a mixed ester Compound
D6. Treatment of Compound D6 with chlorotrimethyisilane in the presence of a
suitable base such as sodium hydride, potassium hydride, LDA or the like gave rise to
an intermediate silyl ketene acetal which rearranged upon heating in a suitable solvent
such as THF or Et2O to a mixed ester Compound D7. Decarboxylation of the ester
Compound D7 to form Compound D8 was accomplished upon heating Compound D7
under vacuum. Reduction of the double bond in Compound D8 was accomplished
under standard hydrogenation conditions, applying a hydrogen overpressure (of from
about 10 to about 50 psi) in the presence of an appropriate catalyst such as 5 or 10%
palladium on carbon resulted in formation of a target compound Compound Al in

carbalkoxymethylenc triphenylphosphorane (Wittig reaction) or a trialkyl
phosphonoacetate (Homer-Emmons reaction) resulted in the formation of an a,ß-
unsaturated ester Compound E2. Treatment of Compound E2 under acidic conditions
(using an acid such as a 1:1 mixture of TFA in DCM, 4N HC1 in dioxane or the like)
resulted in the removal of the Boc-protective group, resulting in formation of a
substituted piperidine Compound E3. Coupling of the piperidine Compound E3 with a

D8 was removed under acidic conditions (using an acid such as a 1:1 mixture of TFA
in DCM, 4N HO in dioxane or the like) to yield a substituted piperidinc Compound
Gl. Coupling of the piperidinc Compound Gl with a carboxylic acid Compound A3
under standard coupling conditions (using a mixture of coupling agents such as
HOBt/EDC, HOBT/HBTU or isobutyl chloroformate in the presence of a suitable base
such as NMM or DIEA) led to formation of an ester Compound G2. The ester
Compound G2 was be converted to Compound G3 upon exposure to strong acidic or
basic aqueous conditions (in the presence of a strong acid or base such as concentrated
HC1 or NaOH). The double bond in Compound G3 was reduced using standard
hydrogenation conditions, applying hydrogen overpressure (of from about 10 to about
50 psi) in the presence of an appropriate catalyst such as 5 or 10% palladium on carbon

(wherein R1 for a compound of Formula (1.3) is -NH(R5), W is -(CH2)0-4alkyl- and an
R5 heteroaryl subtituent is reduced to a partially unsaturated heterocyclyl substitucnt)
by reduction of the double bond in a Compound G3a (wherein R1 in a Compound G3 is
-NH(R5)) using standard hydrogenation conditions, applying hydrogen overpressure (of

defined, R1 is H, and W is-(CH2)0-4alkyl-). Condensation of a Compound A2 under
standard coupling conditions (using a mixture of coupling agents such as HOBt/EDC,
HOBT/HBTU or isobutyl chloroformate in the presence of a suitable base such as

hydrogenation conditions, applying hydrogen overpressure (of from about 10 to about
50 psi) in the presence of an appropriate catalyst such as 5 or 10% palladium on carbon,
accompanied by standard reduction of R2 to yield a target Compound Ala. Compound
Ala can be separated into its individual optical isomers by chiral chromatography at
this stage. In addition, Compound Ala can be alkylated on the R2 heteroatom using the

that has been deprotccted). The double bond in Compound C5b (wherein R2 in a
Compound C5 is an O-protected hydroxyaryl, N-protected anilino, or S-protected
throaryl substituent) was reduced under standard hydrogenation conditions, applying
hydrogen overpressure (of from about 10 to about 50 psi) in the presence of an
appropriate catalyst such as 5% or 10% palladium on carbon, accompanied by removal
of the protective group to yield hydroxyaryl or anilino compound Alb. Alternatively,
the protective group can be removed via basic or acidic hydrolysis in a subsequent step.
Scheme L

Scheme M
Scheme M describes a method for preparing a target compound of Formula (15)
(wherein Rl and W are as previously defined ). The ketone Compound C3 was
converted to a mixture of cis and trans isomers of an a,ß-unsaturated nitriles
Compound M2 upon reaction with an appropriately substituted phosphorane or
phosphonate Compound Ml in the presence of a base such as LiHMDS, NaHMDS,
LDA or the like. Conversion of Compound M2 to Compound M3 was accomplished
under hydrogenolysis conditions (wherein a hydrogen overpressure of about 5 psi was
used) in the presence of an appropriate catalyst such as 5 or 10% palladium on carbon.
Removal of the Boc-protective group from Compound M3 was accomplished under
acidic conditions (by using an acid such as an acidic mixture of TFA and DCM or an
inorganic acid in an appropriate solvent such as dioxane) and resulted in formation of a
piperidinc Compound M4. Coupling of the piperidine Compound M4 with a
carboxylic acid Compound A3 under standard coupling conditions (by using a mixture
of coupling agents such as HOBt/EDC, HOBT/HBTU or isobutyl chloroformate in the
presence of a suitable base such as NMM or DIEA) afforded the nitrile Compound M5.
Hydrolysis of the nitrile Compound M5 under acidic conditions yielded a target
compound of Formula (15).
Scheme N

chlorochromate or the like. Coupling of the aldehyde Compound N2 with a. piperidine
Compound A2 under standard reductive animation conditions using a reducing agent
such as sodium triacetoxyborohydride or the like afforded the ester Compound N3.
Hydrolysis of the ester Compound N3 under acidic or basic conditions yielded a target
compound Formula (II).

mixture was heated for 4 h at 60 °C. H2O (0.5 mL) was added and the mixture was
stirred overnight at rt. The reaction mixture was evaporated, DCM (250 mL) was
added and the mixture was dried (Na2SO4). After filtration and evaporation, the residue
was heated at 130 °C for 2 h under vacuum. Purification by flash column
chromatography (eluent: 1% MeOH in DCM) gave Compound 13f as a yellow oil.
A solution of Compound 13f (0.375 g, 0.88 mmol) in MeOH (50 mL) was
hydrogenated in the presence of 10% palladium on carbon (120 mg) at 1 psi of
hydrogen for 2 h. The catalyst was removed by filtration over celite and the solvent
was evaporated to give a crude Compound 13g, which was used as such for the next
reaction. TFA (10 mL) was added to a solution of Compound 13g (0.35 g, 0.82 mmol)
in DCM (10 mL). The mixture was stirred at rt for 1 h and concentrated under vacuum
to give crude Compound ]3h, which was used as such for the next reaction.

To a THF (166 mL) solution of trimethyl phosphonoacetate (11.65 mL, 80.58 mmol)
was added dropwise NaHMDS (1.0M in THF; 67.2 mL, 67.15 mmol) over a period of
10 min at -78 °C. The resulting partially solidified mixture was stirred at -50°C for 20
min. To the resulting thick solidified mixture, a THF (119 mL) solution of the ketone
Compound 15b (4.76 g, 13.43 mmol) was added at -50 °C over a period of 5 min.
After the addition, the cooling bath was changed to a water bath and it was stirred for

J,. 1998, 330, 861). Human avß3 (Chemicon International Inc., Temecula; CA), at a
concentration of 1 µg/ml dissolved in Tris buffer (20 mM Tris, 1 mM CaCl2, 1 mM
MgCl2, 10 µM MnCl2, 150 mM NaCl), was immobilized on Immulon 96 well plates
(Dynex Technologies, Chantilly, VA)' overnight at 4 °C. Plates were washed and
treated with blocking buffer (3 % BSA in Tris buffer) for 2 h at 37 °C. Plates were then
rinsed 2 times with assay buffer comprised of Tris buffer. Synthesized compounds
were added to wells in duplicate immediately prior to the addition of 2 nM vitroncctin
(Sigma, St. Louis, MO). Following a 3 hour incubation at 37 °C, plates were washed 5
i
times in assay buffer. An anti-human vitronectin IgG rabbit polyclonal antibody
(Calbiochem, San Diego, CA) was added (1:2000) and plates were incubated for 1 hour
at room temperature. VectaStain ABC peroxidase kit reagents (Vector Laboratories,
Burlingame, CA) employing a biotin labeled anti-rabbit IgG, were utilized for detection
of bound antibody. Plates were read at 490 nm on a Molecular Devices (Sunnyvale,
CA) microplate reader. Table 1 shows the results of the in vitro solid phase purified
avß3 binding assay for representative compounds of the present invention.
