BACKGROUND OF THE INVENTION
Field of the Invention
[0001] The invention provides a novel class of compounds, pharmaceutical
compositions comprising such compounds and methods of using such compounds to treat or prevent diseases or disorders associated with abnormal or deregulated kinase activity, particularly diseases or disorders that involve abnormal activation of Abl, Bcr-Abl, Bmx, BTK, b-RAF, c-RAF, CSK, cSRC, Fes, FGFR3, Flt3, IKKα, IKKß, JNK1α1, JNK2α2, Lck, Met, MKK4, MKK6, p70S6K, PAK2, PDGFRα, PKA, PKCα, PKD2, ROCK-II, Ros, Rskl, SAPK2α, SAPK2ß, SAPK3, SAPK4, SGK, Syk, Tie2 and TrkB kinases.
Background
[0002] The protein kinases represent a large family of proteins, which play a
central role in the regulation of a wide variety of cellular processes and maintaining control
over cellular function. A partial, non-limiting, list of these kinases include: receptor
tyrosine kinases such as platelet-derived growth factor receptor kinase (PDGF-R), the nerve
growth factor receptor, trkB, Met, and the fibroblast growth factor receptor, FGFR3; non-
receptor tyrosine kinases such Abl and the fusion kinase BCR-Abl, Lck, Csk, Fes, Bmx and
c-src; and serine/threonine kinases such as c-RAF, sgk, MAP kinases (e.g., MKK4, MKK6,
etc.) and SAPK2a, SAPK2J3 and SAPK3. Aberrant kinase activity has been observed in
many disease states including benign and malignant proliferative disorders as well as
diseases resulting from inappropriate activation of the immune and nervous systems.
[0003] The novel compounds of this invention inhibit the activity of one or more
protein kinases and are, therefore, expected to be useful in the treatment of kinase-associated diseases.

[0026] "Mutant forms of BCR-Abl" means single or multiple amino acid changes
from the wild-type sequence. Mutations in BCR-ABL act by disrupting critical contact points between protein and inhibitor (for example, Gleevec, and the like), more often, by inducing a transition from the inactive to the active state, i.e. to a conformation to which BCR-ABL and Gleevec is unable to bind. From analyses of clinical samples, the repertoire of mutations found in association with the resistant phenotype has been increasing slowly but inexorably over time. Mutations seem to cluster in four main regions. One group of mutations (G250E, Q252R, Y253F/H, E255K/V) includes amino acids that form the phosphate-binding loop for ATP (also known as the P-loop). A second group (V289A, F311L, T315I, F317L) can be found in the Gleevec binding site and interacts directly with the inhibitor via hydrogen bonds or Van der Waals' interactions. The third group of mutations (M351T, E355G) clusters in close proximity to the catalytic domain. The fourth group of mutations (H396R/P) is located in the activation loop, whose conformation is the molecular switch controlling kinase activation/inactivation. BCR-ABL point mutations associated with Gleevec resistance detected in CML and ALL patients include: M224V, L248V, G250E, G250R, Q252R, Q252H, Y253H, Y253F, E255K, E255V, D276G, T277A, V289A, F311L, T315I, T315N, F317L, M343T, M315T, E355G, F359V, F359A, V379I, F382L, L387M, L387F, H396P, H396R, A397P, S417Y, E459K, and F486S (Amino acid . positions, indicated by the single letter code, are those for the GenBank sequence, accession number AAB60394, and correspond to ABL type la; Martinelli et al., Haematologica/The
Hematology Journal, 2005, April; 90-4). Unless otherwise stated for this invention, Bcr-Abl refers to wild-type and mutant forms of the enzyme.
[0027] "Treat", "treating" and "treatment" refer to a method of alleviating or
abating a disease and/or its attendant symptoms.
Description of the Preferred Embodiments
[0028] The fusion protein BCR-Abl is a result of a reciprocal translocation that
fuses the Abl proto-oncogene with the Bcr gene. BCR-Abl is then capable of transforming B-cells through the increase of mitogenic activity. This increase results in a reduction of sensitivity to apoptosis, as well as altering the adhesion and homing of CML progenitor cells. The present invention provides compounds, compositions and methods for the treatment of kinase related disease, particularly Abl, Bcr-Abl, Bmx, BTK, b-RAF, c-RAF, CSK, cSRC, Fes, FGFR3, Flt3, IKKα, IKKß, JNK1α1, JNK2α2, Lck, Met, MKK4, MKK6, p70S6K, PAK2, PDGFRα, PKA, PKCα, PKD2, ROCK-II, Ros, Rskl, SAPK2α, SAPK2ß, SAPK3, SAPK4, SGK, Syk, Tie2 and TrkB kinase related diseases. For example, leukemia and other proliferation disorders related to BCR-Abl can be treated through the inhibition of wild type and mutant forms of Bcr-Abl.

[0041] Further preferred compounds of the invention are detailed in the Examples
and Table I, infra.
Pharmacology and Utility
[0042] Compounds of the invention modulate the activity of kinases and, as such,
are useful for treating diseases or disorders in which kinases, contribute to the pathology
and/or symptomology of the disease. Examples of kinases that are inhibited by the
compounds and compositions described herein and against which the methods described
herein are useful include, but are not limited to, Abl and Bcr-Abl.
[0043] Abelson tyrosine kinase (i.e. Abl, c-Abl) is involved in the regulation of
the cell cycle, in the cellular response to genotoxic stress, and in the transmission of
information about the cellular environment through integrin signaling. Overall, it appears
that the Abl protein serves a complex role as a cellular module that integrates signals from
various extracellular and intracellular sources and that influences decisions in regard to cell
cycle and apoptosis. Abelson tyrosine kinase includes sub-types derivatives such as the
chimeric fusion (oncoprotein) BCR-Abl with deregulated tyrosine kinase activity or the v- •
Abl. BCR-Abl is critical in the pathogenesis of 95% of chronic myelogenous leukemia
(CML) and 10% of acute lymphocytic leukemia. STI-571 (Gleevec) is an inhibitor of the
oncogenic BCR-Abl tyrosine kinase and is used for the treatment of chronic myeloid
leukemia (CML). However, some patients in the blast crisis stage of CML are resistant to
STI-571 due to mutations in the BCR-Abl kinase. Over 22 mutations have been reported to
date with the most common being G250E, E255V, T315I, F317L and M351T.
[0044] Compounds of the present invention inhibit abl kinase, especially v-abl
kinase. The compounds of the present invention also inhibit wild-type BCR-Abl kinase and mutations of BCR-Abl kinase and are thus suitable for the treatment of Bcr-abl-positive cancer and tumor diseases, such as leukemias (especially chronic myeloid leukemia and acute lymphoblastic leukemia, where especially apoptotic mechanisms of action are found), and also shows effects on the subgroup of leukemic stem cells as well as potential for the purification of these cells in vitro after removal of said cells (for example, bone marrow removal) and reimplantation of the cells once they have been cleared of cancer cells (for example, reimplantation of purified bone marrow cells).
[0045] The Ras-Raf-MEK-ERK signaling pathway mediates cellular response to
growth signals. Ras is mutated to an oncogenic form in -15% of human cancer. The Raf
family belongs to the serine/threonine protein kinase and it includes three members, A-Raf,
B-Raf and c-Raf (or Raf-1). The focus on Raf being a drug target has centered on the
relationship of Raf as a downstream effector of Ras. However, recent data suggests that B-
Raf may have a prominent role in the formation of certain tumors with no requirement for
an activated Ras allele (Nature 417, 949 - 954 (01 Jul 2002). In particular, B-Raf
mutations have been detected in a large percentage of malignant melanomas.
[0046] Existing medical treatments for melanoma are limited in their
effectiveness, especially for late stage melanomas. The compounds of the present invention
also inhibit cellular processes involving b-Raf kinase, providing a new therapeutic
opportunity for treatment of human cancers, especially for melanoma.
[0047] The compounds of the present invention also inhibit cellular processes
involving c-Raf kinase. c-Raf is activated by the ras oncogene, which is mutated in a wide
number of human cancers. Therefore inhibition of the kinase activity of c-Raf may provide
a way to prevent ras mediated tumor growth [Campbell, S. L., Oncogene, 17,1395 (1998)].
[0048] PDGF (Platelet-derived Growth Factor) is a very commonly occurring
growth factor, which plays an important role both in normal growth and also in pathological cell proliferation, such as is seen in carcinogenesis and in diseases of the smooth-muscle cells of blood vessels, for example in atherosclerosis and thrombosis. Compounds of the invention can inhibit PDGF receptor (PDGFR) activity and are, therefore, suitable for the treatment of tumor diseases, such as gliomas, sarcomas, prostate tumors, and tumors of the colon, breast, and ovary.
[0049] Compounds of the present invention, can be used not only as a tumor-
inhibiting substance, for example in small cell lung cancer, but also as an agent to treat non-malignant proliferative disorders, such as atherosclerosis, thrombosis, psoriasis, scleroderma and fibrosis, as well as for the protection of stem cells, for example to combat the hemotoxic effect of chemotherapeutic agents, such as 5-fluoruracil, and in asthma. Compounds of the invention can especially be used for the treatment of diseases, which respond to an inhibition of the PDGF receptor kinase.
[0050] Compounds of the present invention show useful effects in the treatment
of disorders arising as a result of transplantation, for example, allogenic transplantation,
especially tissue rejection, such as especially obliterative bronchiolitis (OB), i.e. a chronic
rejection of allogenic lung transplants. In contrast to patients without OB, those with OB
often show an elevated PDGF concentration in bronchoalveolar lavage fluids.
[0051] Compounds of the present invention are also effective in diseases
associated with vascular smooth-muscle cell migration and proliferation (where PDGF and PDGF-R often also play a role), such as restenosis and atherosclerosis. These effects and the consequences thereof for the proliferation or migration of vascular smooth-muscle cells in vitro and in vivo can be demonstrated by administration of the compounds of the present invention, and also by investigating its effect on the thickening of the vascular intima following mechanical injury in vivo.
[0052] The trk family of neurotrophin receptors (trkA, trkB, trkC) promotes the
survival, growth and differentiation of the neuronal and non-neuronal tissues. The TrkB
protein is expressed in neuroendocrine-type cells in the small intestine and colon, in the
alpha cells of the pancreas, in the monocytes and macrophages of the lymph nodes and of .
the spleen, and in the granular layers of the epidermis (Shibayama and Koizumi, 1996).
Expression of the TrkB protein has been associated with an unfavorable progression of
Wilms tumors and of neuroblastomas. TkrB is, moreover, expressed in cancerous prostate
cells but not in normal cells. The signaling pathway downstream of the trk receptors
involves the cascade of MAPK activation through the Shc, activated Ras, ERK-1 and ERK-
2 genes, and the PLC-gammal transduction pathway (Sugimoto et al., 2001).
[0053] The kinase, c-Src transmits oncogenic signals of many receptors. For
example, over-expression of EGFR or HER2/neu in tumors leads to the constitutive activation of c-src, which is characteristic for the malignant cell but absent from the normal cell. On the other hand, mice deficient in the expression of c-src exhibit an osteopetrotic phenotype, indicating a key participation of c-src in osteoclast function and a possible involvement in related disorders.
[0054] The Tec family kinase, Bmx, a non-receptor protein-tyrosine kinase,
controls the proliferation of mammary epithelial cancer cells.
[0055] Fibroblast growth factor receptor 3 was shown to exert a negative
regulatory effect on bone growth and an inhibition of chondrocyte proliferation.
Thanatophoric dysplasia is caused by different mutations in fibroblast growth factor
receptor 3, and one mutation, TDII FGFR3, has a constitutive tyrosine kinase activity which
activates the transcription factor Stall, leading to expression of a cell-cycle inhibitor,
growth arrest and abnormal bone development (Su et al., Nature, 1997, 386, 288-292).
FGFR3 is also often expressed in multiple myeloma-type cancers. Inhibitors of FGFR3
activity are useful in the treatment of T-cell mediated inflammatory or autoimmune diseases
including but not limited to rheumatoid arthritis (RA), collagen II arthritis, multiple
sclerosis (MS), systemic lupus erythematosus (SLE), psoriasis, juvenile onset diabetes,
Sjogren's disease, thyroid disease, sarcoidosis, autoimmune uveitis, inflammatory bowel
disease (Crohn's and ulcerative colitis), celiac disease and myasthenia gravis.
[0056] The activity of serum and glucocorticoid-regulated kinase (SGK), is
correlated to perturbed ion-channel activities, in particular, those of sodium and/or potassium channels and compounds of the invention can be useful for treating hypertension.
[0057] Lin et al (1997) J. Clin. Invest. 100, 8: 2072-2078 and P. Lin (1998)
PNAS 95, 8829-8834, have shown an inhibition of tumor growth and vascularization and also a decrease in lung metastases during adenoviral infections or during injections of the extracellular domain of Tie-2 (Tek) in breast tumor and melanoma xenograft models. Tie2 inhibitors can be used in situations where neovascularization takes place inappropriately (i.e. in diabetic retinopathy, chronic inflammation, psoriasis, Kaposi's sarcoma, chronic neovascularization due to macular degeneration, rheumatoid arthritis, infantile haemangioma and cancers).
[0058] Lck plays a role in T-cell signaling. Mice that lack the Lck gene have a
poor ability to develop thymocytes. The function of Lck as a positive activator of T-cell signaling suggests that Lck inhibitors may be useful for treating autoimmune disease such as rheumatoid arthritis.
[0059] JNKs, along with other MAPKs, have been implicated in having a role in'
mediating cellular response to cancer, thrombin-induced platelet aggregation, immunodeficiency disorders, autoimmune diseases, cell death, allergies, osteoporosis and
heart disease. The therapeutic targets related to activation of the INK pathway include chronic myelogenous leukemia (CML), rheumatoid arthritis, asthma, osteoarthritis, ischemia, cancer and neurodegenerative diseases. As a result of the importance of INK activation associated with liver disease or episodes of hepatic ischemia, compounds of the invention may also be useful to treat various hepatic disorders. A role for INK in cardiovascular disease such as myocardial infarction or congestive heart failure has also been reported as it has been shown INK mediates hypertrophic responses to various forms of cardiac stress. It has been demonstrated that the INK cascade also plays a role in T-cell activation, including activation of the IL-2 promoter. Thus, inhibitors of INK may have therapeutic value in altering pathologic immune responses. A role for INK activation hi various cancers has also been established, suggesting the potential use of JNK inhibitors hi cancer. For example, constitutively activated JNK is associated with HTLV-1 mediated tumorigenesis [Oncogene 13:135-42 (1996)]. JNK may play a role in Kaposi's sarcoma (KS). Other proliferative effects of other cytokines implicated in KS proliferation, such as vascular endothelial growth factor (VEGF), IL-6 and TNFa, may also be mediated by JNK. hi addition, regulation of the c-jun gene in p210 BCR-ABL transformed cells corresponds -with activity of JNK, suggesting a role for JNK inhibitors in the treatment for chronic myelogenous leukemia (CML) [Blood 92:2450-60 (1998)].
[0060] Certain abnormal proliferative conditions are believed to be associated
with raf expression and are, therefore, believed to be responsive to inhibition of raf expression. Abnormally high levels of expression of the raf protein are also implicated in transformation and abnormal cell proliferation. These abnormal proliferative conditions are also believed to be responsive to inhibition of raf expression. For example, expression of the c-raf protein is believed to play a role in abnormal cell proliferation since it has been reported that 60% of all lung carcinoma cell lines express unusually high levels of c-raf mRNA and protein. Further examples of abnormal proliferative conditions are hyper-proliferative disorders such as cancers, tumors, hyperplasia, pulmonary fibrosis, angiogenesis, psoriasis, atherosclerosis and smooth muscle cell proliferation in the blood vessels, such as stenosis or restenosis following angioplasty. The cellular signaling pathway of which raf is a part has also been implicated in inflammatory disorders
characterized by T-cell proliferation (T-cell activation and growth), such as tissue graft
rejection, endotoxin shock, and glomerular nephritis, for example.
[0061] The stress activated protein kinases (SAPKs) are a family of protein
kinases that represent the penultimate step in signal transduction pathways that result in activation of the c-jun transcription factor and expression of genes regulated by c-jun. In particular, c-jun is involved in the transcription of genes that encode proteins involved in the repair of DNA that is damaged due to genotoxic insults. Therefore, agents that inhibit SAPK activity in a cell prevent DNA repair and sensitize the cell to agents that induce DNA damage or inhibit DNA synthesis and induce apoptosis of a cell or that inhibit cell proliferation.
[0062] Mitogen-activated protein kinases (MAPKs) are members of conserved
signal transduction pathways that activate transcription factors, translation factors and other
target molecules in response to a variety of extracellular signals. MAPKs are activated by
phosphorylation at a dual phosphorylation motif having the sequence Thr-X-Tyr by
mitogen-activated protein kinase kinases (MKKs). In higher eukaryotes, the physiological
role of MAPK signaling has been correlated with cellular events such as proliferation,
oncogenesis, development and differentiation. Accordingly, the ability to regulate signal
transduction via these pathways (particularly via MKK4 and MKK6) could lead to the
development of treatments and preventive therapies for human diseases associated with
MAPK signaling, such as inflammatory diseases, autoimmune diseases and cancer.
[0063] The family of human ribosomal S6 protein kinases consists of at least 8
members (RSK1, RSK2, RSK3, RSK4, MSK1, MSK2, p70S6K and p70S6 Kb). Ribosomal protein S6 protein kinases play important pleotropic functions, among them is a key role in the regulation of mRNA translation during protein biosynthesis (Ear. J. Biochem 2000 November; 267(21): 6321-30, Exp Cell Res. Nov. 25, 1999; 253 (1): 100-9, Mol Cell Endocrinol. May 25,1999;151(l-2):65-77). The phosphorylation of the S6 ribosomal protein by p70S6 has also been implicated in the regulation of cell motility (Immunol. Cell Biol. 2000 August;78(4):447-51) and cell growth (Prog. Nucleic Acid Res. Mol. Biol., 2000;65:101-27), and hence, may be important in tumor metastasis, the immune response and tissue repair as well as other disease conditions.
[0064] The SAPK's (also called "jun N-terminal kinases" or "JNK's") are a family
of protein kinases that represent the penultimate step in signal transduction pathways that
result in activation of the c-jun transcription factor and expression of genes regulated by c-
jun. In particular, c-juri is involved in the transcription of genes that encode proteins
involved in the repair of DNA that is damaged due to genotoxic insults. Agents that inhibit
SAPK activity in a cell prevent DNA repair and sensitize the cell to those cancer therapeutic
modalities that act by inducing DNA damage.
[0065] BTK plays a role in autoimmune and/or inflammatory disease such as
systemic lupus erythematosus (SLE), rheumatoid arthritis, multiple vasculitides, idiopathic
thrombocytopenic purpura (ITP), myasthenia gravis, and asthma.. Because of BTK's role in
B-cell activation, inhibitors of BTK are useful as inhibitors of B-cell mediated pathogenic
activity, such as autoantibody production, and are useful for the treatment of B-cell
lymphoma and leukemia.
[0066] CHK2 is a member of the checkpoint kinase family of serine/threonine
protein kinases and is involved in a mechanism used for surveillance of DNA damage, such
as damage caused by environmental mutagens and endogenous reactive oxygen species. As
a result, it is implicated as a tumor suppressor and target for cancer therapy.
[0067] CSK influences the metastatic potential of cancer cells, particularly colon
cancer.
[0068] Fes is a non-receptor protein tyrosine kinase that has been implicated in a
variety of cytokine signal transduction pathways, as well as differentiation of myeloid cells.
Fes is also a key component of the granulocyte differentiation machinery.
[0069] Flt3 receptor tyrosine kinase activity is implicated in leukemias and
myelodysplastic syndrome. In approximately 25% of AML the leukemia cells express a
constitutively active form of auto-phosphorylated (p) FLT3 tyrosine kinase on the cell
surface. The activity of p-FLT3 confers growth and survival advantage on the leukemic
cells. Patients with acute leukemia, whose leukemia cells express p-FLT3 kinase activity,
have a poor overall clinical outcome. Inhibition of p-FLT3 kinase activity induces apoptosis
(programmed cell death) of the leukemic cells.
[0070] Inhibitors of IKKα and IKKß (1 & 2) are therapeutics for diseases which
include rheumatoid artliritis, transplant rejection, inflammatory bowel disease,
osteoarthritis, asthma, chronic obstructive pulmonary disease, atherosclerosis, psoriasis,
multiple sclerosis, stroke, systemic lupus erythematosus, Alzheimer's disease, brain
ischemia, traumatic brain injury, Parkinson's disease, amyotrophic lateral sclerosis,
subarachnoid hemorrhage or other diseases or disorders associated with excessive
production of inflammatory mediators in the brain and central nervous system.)
[0071] Met is associated with most types of the major human cancers and
expression is often correlated with poor prognosis and metastasis. Inhibitors of Met are
therapeutics for diseases which include cancers such as lung cancer, NSCLC (non small cell
lung cancer), bone cancer, pancreatic cancer, skin cancer, cancer of the head and neck,
cutaneous or intraocular melanoma, uterine cancer, ovarian cancer, rectal cancer, cancer of
the anal region, stomach cancer, colon cancer, breast cancer, gynecologic tumors (e. g.,
uterine sarcomas, carcinoma of the fallopian tubes, carcinoma of the endometrium,
carcinoma of the cervix, carcinoma of the vagina or carcinoma of the vulva), Hodgkin's
Disease, cancer of the esophagus, cancer of the small intestine, cancer of the endocrine
system (e. g., cancer of the thyroid, parathyroid or adrenal glands), sarcomas of soft tissues,
cancer of the urethra, cancer of the penis, prostate cancer, chronic or acute leukemia, solid -
tumors of childhood, lymphocytic lymphomas, cancer of the bladder, cancer of the kidney
or ureter (e. g., renal cell carcinoma, carcinoma of the renal pelvis), pediatric malignancy,
neoplasms of the central nervous system (e. g., primary CNS lymphoma, spinal axis tumors,
brain stem glioma or pituitary adenomas), cancers of the blood such as acute myeloid
leukemia, chronic myeloid leukemia, etc, Barrett's esophagus (pre-malignant syndrome)
neoplastic cutaneous disease, psoriasis, mycoses fungoides and benign prostatic
hypertrophy, diabetes related diseases such as diabetic retinopathy, retinal ischemia and
retinal neovascularization, hepatic cirrhosis, cardiovascular disease such as atherosclerosis,
immunological disease such as autoimmune disease and renal disease. Preferably, the
disease is cancer such as acute myeloid leukemia and colorectal cancer.
[0072] The Nima-related kinase 2 (Nek2) is a cell cycle-regulated protein kinase
with maximal activity at the onset of mitosis that localizes to the centrosome. Functional studies have implicated Nek2 in regulation of centrosome separation and spindle formation. Nek2 protein is elevated 2- to 5-fold in cell lines derived from a range of human tumors including those of cervical, ovarian, prostate, and particularly breast.
[0073] p70S6K-mediated diseases or conditions include, but are not limited to,
proliferative disorders, such as cancer and tuberous sclerosis.
[0074] There is growing evidence that kinase inhibitor therapy works consistently
and reliably against cancers in which the kinase drug target is constitutively activated by gene mutations. There are multiple reports of mutations found in kinases resulting from a natural tumor selection process. A non-limiting list of examples of these would include: b-raf V599E mutant in over 60% of melanoma cases; FU3-ITD mutants in 30% of AML cases; c-kit mutations in GIST patients; PDGFRcc in GIST and HES; PDGFR0 in CMML; Pi3K mutants in colon and gastric cancers and glioblastomas; and EGFR mutants in 10% of lung cancers (Iressa® responsive) and in glioblastomas.
[0075] In accordance with the foregoing, the present invention further provides a
method for preventing or treating any of the diseases or disorders described above in a subject in need of such treatment, which method comprises administering to said subject a therapeutically effective amount (See, "Administration and Pharmaceutical Compositions ", infra) of a compound of Formula I or a pharmaceutically acceptable salt thereof. For any of the above uses, the required dosage will vary depending on the mode of administration, the" particular condition to be treated and the effect desired.
Administration and Pharmaceutical Compositions
[0076] In general, compounds of the invention will be administered in
therapeutically effective amounts via any of the usual and acceptable modes known in the
art, either singly or in combination with one or more therapeutic agents. A therapeutically
effective amount may vary widely depending on the severity of the disease, the age and
relative health of the subject, the potency of the compound used and other factors. In
general, satisfactory results are indicated to be obtained systemically at daily dosages of
from about 0.03 to 2.5mg/kg per body weight. An indicated daily dosage in the larger
mammal, e.g. humans, is in the range from about 0.5mg to about 100mg, conveniently
administered, e.g. in divided doses up to four times a day or in retard form. Suitable unit
dosage forms for oral administration comprise from ca. 1 to 50mg active ingredient.
[0077] Compounds of the invention can be administered as pharmaceutical
compositions by any conventional route, in particular enterally, e.g., orally, e.g., in the form
of tablets or capsules, or parenterally, e.g., in the form of injectable solutions or suspensions, topically, e.g., in the form of lotions, gels, ointments or creams, or in a nasal or suppository form. Pharmaceutical compositions comprising a compound of the present invention in free form or in a pharmaceutically acceptable salt form in association with at least one pharmaceutically acceptable carrier or diluent can be manufactured in a conventional manner by mixing, granulating or coating methods. For example, oral compositions can be tablets or gelatin capsules comprising the active ingredient together with a) diluents, e.g., lactose, dextrose, sucrose, mannitol, sorbitol, cellulose and/or glycine; b) lubricants, e.g., silica, talcum, stearic acid, its magnesium or calcium salt and/or polyethyleneglycol; for tablets also c) binders, e.g., magnesium aluminum silicate, starch paste, gelatin, tragacanth, methylcellulose, sodium carboxymethylcellulose and or polyvinylpyrrolidone; if desired d) disintegrants, e.g., starches, agar, alginic acid or its sodium salt, or effervescent mixtures; and/or e) absorbents, colorants, flavors and sweeteners. Injectable compositions can be aqueous isotonic solutions or suspensions, and suppositories can be prepared from fatty emulsions or suspensions. The compositions may be sterilized and/or contain adjuvants, such as preserving, stabilizing, wetting or emulsifying agents, solution promoters, salts for regulating the osmotic pressure and/or buffers. In addition, they may also contain other therapeutically valuable substances. Suitable formulations for transdermal applications include an effective amount of a compound of the present invention with a carrier. A carrier can include absorbable pharmacologically acceptable solvents to assist passage through the skin of the host. For example, transdermal devices are in the form of a bandage comprising a backing member, a reservoir containing the compound optionally with carriers, optionally a rate controlling barrier to deliver the compound to the skin of the host at a controlled and predetermined rate over a prolonged period of time, and means to secure the device to the skin. Matrix transdermal formulations may also be used. Suitable formulations for topical application, e.g , to the skin and eyes, are preferably aqueous solutions, ointments, creams or gels well-known in the art. Such may contain solubilizers, stabilizers, tonicity enhancing agents, buffers and preservatives.
[00 78] Compounds of the invention can be administered in therapeutically
effective amounts in combination with one or more therapeutic agents (pharmaceutical
combinations). For example, synergistic effects can occur with other immunomodulatory or
anti-inflammatory substances, for example when used in combination with cyclosporin,
rapamycin, or ascomycin, or immunosuppressant analogues thereof, for example
cyclosporin A (CsA), cyclosporin G, FK-506, rapamycin, or comparable compounds,
corticosteroids, cyclophosphamide, azathioprine, methotrexate, brequinar, leflunomide,
mizoribine, mycophenolic acid, mycophenolate mofetil, 15-deoxyspergualin,
immunosuppressant antibodies, especially monoclonal antibodies for leukocyte receptors,
for example MHC, CD2, CD3, CD4, CD7, CD25, CD28, B7, CD45, CD58 or their ligands,
or other immunomodulatory compounds, such as CTLA41g. Where the compounds of the
invention are administered in conjunction with other therapies, dosages of the co-
administered compounds will of course vary depending on the type of co-drug employed,
on the specific drug employed, on the condition being treated and so forth.
[0079] The invention also provides for a pharmaceutical combinations, e.g. a kit,
comprising a) a first agent which is a compound of the invention as disclosed herein, in free form or in pharmaceutically acceptable salt form, and b) at least one co-agent. The kit can comprise instructions for its administration.
[0080] The terms "co-administration" or "combined administration" or the like as
utilized herein are meant to encompass administration of the selected therapeutic agents to a
single patient, and are intended to include treatment regimens in which the agents are not
necessarily administered by the same route of administration or at the same time.
[0081] The term "pharmaceutical combination" as used herein means a product
that results from the mixing or combining of more than one active ingredient and includes both fixed and non-fixed combinations of the active ingredients. The term "fixed combination" means that the active ingredients, e.g. a compound of Formula I and a co-agent, are both administered to a patient simultaneously in the form of a single entity or dosage. The term "non-fixed combination" means that the active ingredients, e.g. a compound of Formula I and a co-agent, are both administered to a patient as separate entities either simultaneously, concurrently or sequentially with no specific time limits, wherein such administration provides therapeutically effective levels of the 2 compounds in the body of the patient. The latter also applies to cocktail therapy, e.g. the administration of 3 or more active ingredients.
Processes for Making Compounds of the Invention
[0082] The present invention also includes processes for the preparation of
compounds of the invention. In the reactions described, it can be necessary to protect
reactive functional groups, for example hydroxy, amino, imino, thio or carboxy groups,
where these are desired in the final product, to avoid their unwanted participation in the
reactions. Conventional protecting groups can be used in accordance with standard
practice, for example, see T.W. Greene and P. G. M. Wuts in "Protective Groups in Organic
Chemistry", John Wiley and Sons, 1991.
[0083] Compounds of Formula I can be prepared by proceeding as in the
following Reaction Scheme I:
Reaction Scheme I
(Scheme Removed)
[0084] in which n, R1, R2, R3, R4, R7, Y1 and Y2 are as defined in the Summary of
the Invention. A compound of Formula I can be synthesized by reacting a compound of formula 2 with a compound of formula 3 in the presence of a suitable solvent (for example, dichloromethane, and the like) and a suitable base (for example, diisopropylethylamine, and the like). The reaction proceeds in a temperature range of about 0°C to about 40°C and can take up to about 10 hours to complete. The reaction mixture is optionally further reacted to remove any protecting groups.
[0085] Detailed examples of the synthesis of a compound of Formula I can be
found in the Examples, infra.

Additional Processes for Making Compounds of the Invention
[0086] A compound of the invention can be prepared as a pharmaceutically
acceptable acid addition salt by reacting the free base form of the compound with a
pharmaceutically acceptable inorganic or organic acid. Alternatively, a pharmaceutically
acceptable base addition salt of a compound of the invention can be prepared by reacting the
free acid form of the compound with a pharmaceutically acceptable inorganic or organic
base.
[0087] Alternatively, the salt forms of the compounds of the invention can be
prepared using salts of the starting materials or intermediates.
[0088] The free acid or free base forms of the compounds of the invention can be
prepared from the corresponding base addition salt or acid addition salt from, respectively.
For example a compound of the invention in an acid addition salt form can be converted to
the corresponding free base by treating with a suitable base (e.g., ammonium hydroxide
solution, sodium hydroxide, and the like). A compound of the invention in a base addition
sa't form can be converted to the corresponding free acid by treating with a suitable acid
(e.g., hydrochloric acid, etc.).
[0089] Compounds of the invention in unoxidized form can be prepared from N-
oxides of compounds of the invention by treating with a reducing agent (e.g., sulfur, sulfur
dioxide, triphenyl phosphine, lithium borohydride, sodium borohydride, phosphorus
trichloride, tribromide, or the like) in a suitable inert organic solvent (e.g. acetonitrile,
ethanol, aqueous dioxane, or the like) at 0 to 80°C.
[0090] Prodrug derivatives of the compounds of the invention can be prepared by
methods known to those of ordinary skill in the art (e.g., for further details see Saulnier et
al., (1994), Bioorganic and Medicinal Chemistry Letters, Vol. 4, p. 1985). For example,
appropriate prodrugs can be prepared by reacting a non-derivatized compound of the
invention with a suitable carbamylating agent (e.g., 1,1-acyloxyalkylcarbanochloridate,
para-nitrophenyl carbonate, or the like).
[0091] Protected derivatives of the compounds of the invention can be made by
means known to those of ordinary skill in the art. A detailed description of techniques
applicable to the creation of protecting groups and their removal can be found in T. W.
Greene, "Protecting Groups in Organic Chemistry", 3rd edition, John Wiley and Sons, Inc., 1999.
[0092] Compounds of the present invention can be conveniently prepared, or
formed during the process of the invention, as solvates (e.g., hydrates). Hydrates of compounds of the present invention can be conveniently prepared by recrystallization from an aqueous/organic solvent mixture, using organic solvents such as dioxin, tetrahydrofuran or methanol.
[0093] Compounds of the invention can be prepared as their individual
stereoisomers by reacting a racemic mixture of the compound with an optically active resolving agent to form a pair of diastereoisomeric compounds, separating the diastereomers and recovering the optically pure enantiomers. While resolution of enantiomers can be carried out using covalent diastereomeric derivatives of the compounds of the invention, dissociable complexes are preferred (e.g., crystalline diastereomeric salts). Diastereomers have distinct physical properties (e.g., melting points, boiling points, solubilities, reactivity, etc.) and can be readily separated by taking advantage of these dissimilarities. The diastereomers can be separated by chromatography, or preferably, by separation/resolution techniques based upon differences in solubility. The optically pure enantiomer is then recovered, along with the resolving agent, by any practical means that would not result in racemization. A more detailed description of the techniques applicable to the resolution of stereoisomers of compounds from their racemic mixture can be found in Jean Jacques, Andre Collet, Samuel H. Wilen, "Enantiomers, Racemates and Resolutions", John Wiley And Sons, Inc., 1981.
[0094] In summary, the compounds of Formula I can be made by a process,
which involves:
(a) that of reaction scheme I; and
(b) optionally converting a compound of the invention into a pharniaceutically
acceptable salt;
(c) optionally converting a salt form of a compound of the invention to a non-salt•
form;
(d) optionally converting an unoxidized form of a compound of the invention into
a pharmaceutically acceptable N-oxide;
(e) optionally converting an N-oxide form of a compound of the invention to its
unoxidized form;
(f) optionally resolving an individual isomer of a compound of the invention from
a mixture of isomers;
(g) optionally converting a non-derivatized compound of the invention into a
pharrnaceutically acceptable prodrug derivative; and
(h) optionally converting a prodrug derivative of a compound of the invention to its non-derivatized form.
[0095] Insofar as the production of the starting materials is not particularly
described, the compounds are known or can be prepared analogously to methods known in the art or as disclosed in the Examples hereinafter.
[0096] One of skill in the art will appreciate that the above transformations are
only representative of methods for preparation of the compounds of the present invention, and that other well known methods can similarly be used.
