FIELD OF THE INVENTION
[0001] The present invention is in the field of medicinal chemistry and relates to
pyrimidins compounds that are protein kinase inhibitors, compositions containing such
compounds and methods of use. The compounds are useful for treating cancer,
neurological disorders, autoimmune disorders, and other diseases that are alleviated by
protein kinase inhibitors.
BACKGROUND OF THE INVENTION
[0002] The search for new therapeutic agents has been greatly aided in recent years by
a better understanding of the structure of enzymes and other biomolecules associated with
target diseases. One important class of enzymes that has been the subject of extensive
study is protein kinases.
[0003] Protein kinases constitute a large family of structurally related enzymes that are
responsible for the control of a variety of signal transduction processes within the cell.
(See, Hardie, G. and Hanks, S. (1995) The Protein Kinase Facts Book, I and II, Academic
Press, San Diego, CA). Protein kinases are thought to have evolved from a common
ancestral gene due to the conservation of their structure and catalytic function. Almost all
kinases contain a similar 250-300 amino acid catalytic domain. The kinases may be
categorized into families by the substrates tney phospborylate (e.g., protein-tyrosine,
protein-serine/threonine, lipids, etc.). Sequence motifs have been identified that generally
correspond to each of these kinase families (See, for example, Hanks, S.K., Hunter, T.,
FASEB J., 9:576-596 (1995); Knighton et al., Science, 253:407-414 (1991); Hiles et al.,
Cell, 70:419-429 (1992); Kunz et ai., Cell,73:585-596 (1993); Garcia-Bustos et al.,
EMBO J., 13:2352-2361 (1994)).
[0004] In general, protein kinases mediate intracellular signaling by effecting a
phosphoryl transfer from a nucleoside triphosphate to a protein acceptor that is involved
in a signaling pathway. These phosphorylation events act as molecular on/off switches
that can modulate or regulate the target protein biological function. These
phosphorylation events are ultimately triggered in response to a variety of extracellular
and other stimuli. Examples of such stimuli include environmental and chemical stress
signals (e.g., osmotic shock, heat shock, ultraviolet radiation, bacterial endotoxin, and
H2O2), cytokines (e.g., interleukin-1 (IL-1) and tumor necrosis factor a (TNF-a)), and
growth factors (e.g., granulocyte macrophage-colony-stimulating factor (GM-CSF), and
fibroblast growth factor (FGF)). An extracellular stimulus may affect one or more
cellular responses related to cell growth, migration, differentiation, secretion of
hormones, activation of transcription factors, muscle contraction, glucose metabolism,
control of protein synthesis, and regulation of the cell cycle.
[0005] Many diseases are associated with abnormal cellular responses triggered by
protein kinase-mediated events. These diseases include autoimmune diseases,
inflammatory diseases, bone diseases, metabolic diseases, neurological and
neurodegenerative diseases, cancer, cardiovascular diseases, allergies and asthma,
Alzheimer"s disease and hormone-related diseases. Accordingly, there has been a
substantial effort in medicinal chemistry to find protein kinase inhibitors that are effective
as therapeutic agents. However, considering the lack of currently available treatment
options for the majority of the conditions associated with protein kinases, there is still a
great need for new therapeutic agents that inhibit these protein targets.
[0006] Mammalian cells respond to extracellular stimuli by activating signaling
cascades that are mediated by members of the mitogen-activated protein (MAP) kinase
family, which include the extracellular signal regulated kinases (ERKs), the p38 MAP
kinases and the c-Jun N-terminal kinases (JNKs). MAP kinases (MAPKs) are activated
by a variety of signals including growth factors, cytokines, UV radiation, and stress-
inducing agents. MAPKs are serine/threonme kinases and their activation occur by dual
phosphorylation of threonine and tyrosine at the Thr-X-Tyr segment in the activation
loop. MAPKs phosphorylate various substrates including transcription factors, which in
turn regulate the expression of specific sets of genes and thus mediate a specific response
to the stimulus.
[0007] ERK2 is a widely distributed protein kinase that achieves maximum activity
when both Thr183 and Tyr185 are phosphorylated by the upstream MAP kinase kinase,
MEK1 (Anderson et al., 1990, Nature 343, 651; Crews et al., 1992, Science 258,478).
Upon activation, ERK2 phosphorylates many regulatory proteins, including the protein
kinases Rsk90 (Bjorbaek et al., 1995, J. Biol. Chem. 270, 18848) and MAPKAP2 (Rouse
et al., 1994, Cell 78, 1027), and transcription factors such as ATF2 (Raingeaud et al.,
1996, Mol. Cell Biol. 16, 1247), Elk-1 (Raingeaud et al. 1996), c-Fos (Chen et al., 1993
i?roc. Natl. Acad. Sci. USA 90,10952), and c-Myc (Oliver et al., 1995, Proc. Soc. Exp.
Biol. Med. 210,162). ERK2 is also a downstream target of the Ras/Raf dependent
parnways (Moodie et al., 1993, Science 260,1658) and relays the signals from these
potentially oncogenic proteins. ERK2 has been shown to play a role in the negative
growth control of breast cancer cells (Frey and Mulder, 1997, Cancer Res. 57,628) and
hyperexpression of ERK2 in human breast cancer has been reported (Sivaraman et al.,
1997, J Clin. Invest. 99,1478). Activated ERK2 has also been implicated in the
proliferation of endothelin-stimulated airway smooth muscle cells, suggesting a role for
this kinase in asthma (Whelchel et al., 1997, Am. J. Respir. Cell Mol. Biol. 16, 589).
[0008] Overexpression of receptor tyrosine kinases such as EGFR and ErbB2 (Arteaga
CL, 2002, Semin Oncol. 29, 3-9; Eccles SA, 2001, J Mammary Gland Biol Neoplasia
6:393-406; Mendelsohn J & Baselga J, 2000, Oncogene 19,6550-65), as well as
activating mutations in the Ras GTPase proteins (Nottage M & Siu LL, 2002, Curr Pharm
Des 8,2231-42; Adjei AA, 2001, J Natl Cancer Inst 93, 1062-74) or B-Raf mutants
(Davies H. et al., 2002, Nature 417, 949-54; Brose et al., 2002, Cancer Res 62, 6997-
7000) are major contributors to human cancer. These genetic alterations are correlated
with poor clinical prognosis and result in activation of the Raf-1/2/3 - MEK1/2 - ERK1/2
signal transduction cascade in a broad panel of human tumors. Activated ERK (i.e.
ERK1 and/or ERK2) is a central signaling molecule that has been associated with the
control of proliferation, differentiation, anchorage-independent cell survival, and
angiogenesis, contributing to a number of processes that are important for the formation
and progression of malignant tumors. These data suggest that an ERK1/2 inhibitor will
exert pleiotropic activity, including proapoptotic, anti-proliferative, anti-metastatic and
anti-angiogenic effects, and offer a therapeutic opportunity against a very broad panel of
human tumors.
[0009] There is a growing body of evidence that implicates constitutive activation of
the ERK MAPK pathway in the oncogenic behavior of select cancers. Activating
mutations of Ras are found in 30% of all cancers, with some, such as pancreatic (90%)
and colon (50%) cancer, harboring particularly high mutation rates (ref). Ras mutations
have also been identified in 9-15% of melanomas, but B-Raf somatic missense mutations
conferring constitutive activation are more frequent and found in 60-66% malignant
melanomas. Activating mutations of Ras, Raf and MEK ate able to oncogenically
transform fibroblasts in vitro, and Ras or Raf mutations in conjunction with the loss of a
tumor suppressor gene (e.g. pl6INK4A) can cause spontaneous tumor development in
vivo. Increased ERK activity has been demonstrated in these models and has also been
widely reported in appropriate human tumors. In melanoma, high basal ERK activity
resulting from either B-Raf or N-Ras mutations or autocrine growth factor activation is
well documented and has been associated with rapid tumor growth, increased cell
survival and resistance to apoptosis. Additionally, ERK activation is considered a major
driving force behind the highly metastatic behavior of melanoma associated with
increased expression of both extracellular matrix degrading proteases and invasion-
promoting integrins as well as the downregulation of E-cadherin adhesion molecules that
normally mediate keratinocyte interactions to control melanocyte growth. These data
taken together, indicate ERK as promising therapeutic target for the treatment of
melanoma, a currently untreatable disease.
[0010] One particularly interesting kinase family is the c-Jun NH2-terminal protein
kinases, also known as JNKs. Three distinct genes, JNK1, JNK2, JNK3 have been
identified and at least ten different splicing isoforms of JNKs exist in mammalian cells
[Gupta et al., EMBOJ.. 15:2760-70 (1996)]. Members of the JNK family are activated
by proinflammatory cytokines, such as tumor necrosis factor-a (TNFa) and interleukin-1
ß(IL-1ß), as well as by environmental stress, including anisomycin, UV irradiation,
hypoxia, and osmotic shock [Minden et al., Biochemica et Biophvsica Acta, 1333:F85-
F104 (1997)].
[0011] The down-stream substrates of JNKs include transcription factors c-Jun, ATF-
2, Elkl, p53 and a cell death domain protein (DENN) [Zhang et al. Proc. Natl. Acad. Sci.
USA. 95:2586-91 (1998)]. Each JNK isoform binds to these substrates with different
affinities, suggesting a regulation of signaling pathways by substrate specificity of
different JNKs in vivo (Gupta et al., supra).
[0012] 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 JNK pathway include
chronic myelogenous leukemia (CML), rheumatoid arthritis, asthma, osteoarthritis,
ischemia, cancer and neurodegenerative diseases.
[0013] Several reports have detailed the importance of JNK activation associated with
liver disease or episodes of hepatic ischemia Nat. Genet. 21:326-9 (1999); FKRS Lett.
420:201-4 (1997); J. Clin. Invest. 102:1942-50 (1998V. Hepatology 28:1022-30 (1998)].
Therefore, inhibitors of JNK may be useful to treat various hepatic disorders.
[0014] A role for JNK in cardiovascular disease such as myocardial infarction or
congestive heart failure has also been reported as it has been shown JNK mediates
hypertrophic responses to various forms of cardiac stress fCirc. Res. 83:167-78 (1998);
Circulation 97:1731-7 (1998); J. Biol. Chem. 272:28050-6 (1997); Circ. Res. 79:162-73
(1996); Orc.Res, 78:947-53 (1996): J. Clin. Invest. 97:508-14 (1996)].
[0015] It has been demonstrated that the JNK cascade also plays a role in T-cell
activation, including activation of the IL-2 promoter. Thus, inhibitors of JNK may have
therapeutic value in altering pathologic immune responses [J. Immunol. 162:3176-87
(1999); Eur. J. Immunol. 28:3867-77 (1998); J. Exp. Med. 186:941-53 (1997); Eur.J.
Immunol. 26:989-94 (1996)].
[0016] A role for JNK activation in various cancers has also been established,
suggesting the potential use of JNK inhibitors in 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) because it is thought that the
proliferative effects of bFGP and OSM on KS cells are mediated by their activation of the
JNK signaling pathway [J. Clin. Invest. 99:1798-804 (1997)]. 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. In 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)].
[0017] JNK1 and JNK2 are widely expressed in a variety of tissues. In contrast,
JNK3, is selectively expressed in the brain and to a lesser extent in the heart and testis
[Gupta et al., supra; Mohit et al., Neuron 14:67-78 (1995); Martin et al., Brain Res. Mol.
Brain Res. 35:47-57 (1996)]. JNK3 has been linked to neuronal apoptosis induced by
kainic acid, indicating a role of JNK in the pathogenesis of glutamate neurotoxicity. In

the adult human brain, JNK3 expression is localized to a subpopulation of pyramidal
neurons in the CA1, CA4 and subiculum regions of the hippocampus and layers 3 and 5
of the nebcortex [Mohit et al., supra]. The CA1 neurons of patients with acute hypoxia
showed strong nuclear JNK3-immunoreactivity compared to minimal, diffuse
cytocasmic staining of the hippocampal neurons from brain tissues of normal patients
[Zhang et al., supra]. Thus, JNK3 appears to be involved involved in hypoxic and
ischeraic damage of CA1 neurons in the hippocampus.
[0018] In addition, JNK3 co-localizes immunochemically with neurons vulnerable in
Alzheimer"s disease [Mohit et al., supra]. Disruption of the JNK3 gene caused resistance
of mice to the excitotoxic glutamate receptor agonist kainic acid, including the effects on
seizure activity, AP-1 transcriptional activity and apoptosis of hippocampal neurons,
indicating that the JNK3 signaling pathway is a critical component in the pathogenesis of
glutamate neurotoxicity (Yang et al., Nature. 389:865-870 (1997)).
[0019] Based on these findings, JNK signaling, especially that of JNK3, has been
implicated in the areas of apoptosis-driven neurodegenerative diseases such as
Alzheimer"s Disease, Parkinson"s Disease, ALS (Amyotrophic Lateral Sclerosis),
epilepsy and seizures, Huntington"s Disease, traumatic brain injuries, as well as ischemic
and hemorrhaging stroke.
[0020] AKT (also known as PKB or Rac-PK beta), a serine/threonine protein kinase,
has been shown to be overexpressed in several types of cancer and is a mediator of
normal cell functions [(Khwaja, A., Nature 1999,401,33-34); (Yuan, Z.Q., et al.,
Oncogene 2000, 19, 2324-2330); (Namikawa, K., et al., J Neurosci. 2000,20, 2875-
2886,)]. AKT comprises an N-terminal pleckstrin homology (PH) domain, a kinase
domain and a C-terminal "tail" region. Three isoforms of human AKT kinase (AKT-1, -2
and -3) have been reported so far [(Cheng, J.Q., Proc. Natl. Acad. Sci. USA 1992, 89,
9267-9271); (Brodbeck, D. et al., J. Biol. Chem. 1999,274, 9133-9136)]. The PH
domain binds 3-phosphoinositides, which are synthesized by phosphatidyl inositol 3-
kinase (PDK) upon stimulation by growth factors such as platelet derived growth factor
(PDGF), nerve growth factor (NGF) and insulin-like growth factor (IGF-1) [(Kulik et al.,
Mol. Cell. Biol, 1997,17,1595-1606,); (Heromings, B.A., Science, 1997,275, 628-630)].
lipid binding to the PH domain promotes translocation of AKT to the plasma membrane
and facilitates phosphorylation by another PH-domain-containing protein kinases, PDK1

at Thr308, Thr309, and Thr305 for the AKT isoforms 1, 2 and 3, respectively. A second,
as of yet unknown, kinase is required for the phosphorylation of Ser473, Ser474 or
Ser472 in the C-terminal tails of AKT-1, -2 and -3 respectively, in order to yield a fully
activated AKT enzyme.
[0021] Once localized to the membrane, AKT mediates several functions within the
cell including the metabolic effects of insulin (Calera, M.R. et al., J. Biol. Chem. 1998,
273,7201-7204) induction of differentiation and/or proliferation, protein synthesis and
stress responses (Alessi, D.R. et al., Curr. Opin. Genet. Dev. 1998,8, 55-62,).
[0022] Manifestations of altered AKT regulation appear in both injury and disease, the
most important role being in cancer. The first account of AKT was in association with
human ovarian carcinomas where expression of AKT was found to be amplified in 15%
of cases (Cheng, J.Q. et al., Proc. Natl. Acad Set. U.SA. 1992,89,9267-9271). It has
also been found to be overexpressed in 12% of pancreatic cancers (Cheng, J. Q. et al.,
Proc. Natl. Acad. Sci. U.S.A. 1996,93, 3636-3641). It was demonstrated that AKT-2 was
over-expressed in 12% of ovarian carcinomas and that amplification of AKT was
especially frequent in 50% of undifferentiated tumours, suggesting that AKT is also
associated with tumour aggressiveness (Bellacosa, et al., Int. J. Cancer 1995,64, 280-
285).
[0023] Glycogen synthase kinase-3 (GSK-3) is a serine/threonine protein kinase
comprised of oc and ß isoforms that are each encoded by distinct genes [Coghlan et al.,
Chemistry & Biology, 7, 793-803 (2000); Kim and Kimmel, Curr. Opinion Genetics Dev.,
10, 508-514 (2000)]. GSK-3 has been implicated in various diseases including diabetes,
Alzheimer"s disease, CNS disorders such as manic depressive disorder and
neurodegenerative diseases, and cardiomyocyte hypertrophy [see, e.g., WO 99/65897;
WO 00/38675; Kaytor and Orr, Curr. Opin. Neurobiol., 12,275-8 (2000); Haq et al., J.
Cell Biol., 151,117-30 (2000); Eldar-Finkelman, Trends Mol. Med., 8,126-32 (2002)].
These diseases are associated with the abnormal operation of certain cell signaling
pathways in which GSK-3 plays a role.
[0024] GSK-3 has been found to phosphorylate and modulate the activity of a number
of regulatory proteins. These include glycogen synthase, which is the rate-limiting
enzyme required for glycogen synthesis, the rnicrotubule-associated protein Tau, the gene
transcription factor 3-catenin, the translation initiation factor elF-2B, as well as ATP-

citrate lyase, axin, heat shock factor-1, c-Jun, c-myc, c-myb, CREB, and CEPBa. These
diverse targets implicate GSK-3 in many aspects of cellular metabolism, proliferation,
differentiation and. development.
[0025] In a GSK-3 mediated pathway that is relevant for the treatment of type II
dianeces, insulin-induced signaling leads to cellular glucose uptake and glycogen
synthesis. GSK-3 is a negative regulator of the insulin-induced signal in this pathway.
Normally, the presence of insulin causes inhibition of GSK-3-mediated phosphorylation
and deactivation of glycogen synthase. The inhibition of GSK-3 leads to increased
glycogen synthesis and gucose uptake (Klein et al., PNAS, 93, 8455-9 (1996); Cross et
al., Biochem. J., 303,21-26 (1994); Cohen, Biochem. Soc. Trans., 21, 555-567 (1993);
and Massillon et al., Biochem J. 299,123-128 (1994); Cohen and Frame, Nat. Rev. Mol.
Cell. Biol., 2, 769-76 (2001)]. However, where the insulin response is impaired in a
diabetic patient, glycogen synthesis and glucose uptake fail to increase despite the
presence of relatively high blood levels of insulin. This leads to abnormally high blood
levels of glucose with acute and chronic effects that may ultimately result in
cardiovascular disease, renal failure and blindness. In such patients, the normal insulin-
induced inhibition of GSK-3 fails to occur. It has also been reported that GSK-3 is
overexpressed in patients with type II diabetes [WO 00/38675]. Therapeutic inhibitors of
GSK-3 are therefore useful for treating diabetic patients suffering from an impaired
response to insulin.
[0026] Apoptosis has been implicated in the pathophysiology of ischemic brain
damage (Li et al., 1997; Choi, et al., 1996; Charriaut-Marlangue et al., 1998; Grahm and
Chen, 2001; Murphy et al., 1999; Nicotera et al., 1999). Recent publications indicate that
activation of GSK-3ß may be involved in apoptotic mechanisms (Kaytor and Orr, 2002;
Culbert et al., 2001). Studies in rat models of ischemic stroke induced by middle cerebral
artery occlusion (MCAO) showed increased GSK-3ß expression is following ischemia
(Wang et al., Brain Res, 859,381-5, 2000; Sasaki et al., Neurol Res, 23, 588-92 ,2001).
Fibroblast growth factor (FGF) reduced ischemic brain injury after permanent middle
cerebral artery occlusion (MCO) in rats (Fisher et al. 1995; Song et al. 2002). Indeed, the
neuroprotective effects of FGF demonstrated in ischemia models in rats may be mediated
by a PI-3 kinase/AKT-dependent inactivation of GSK-3ß (Hashimoto et al., 2002). Thus,

inhibition of GSK-3ß after a cerebral ischemic event may ameliorate ischemic brain
damage.
[0027] GSK-3 is also implicated in mycardial infarction. See Jonassen et al., Circ Res,
89:1191,2001 (The reduction in myocardial infarction by insulin administration at
repofusion is mediated via Akt dependent signaling pathway); Matsui et al., Circulation,
104:330,2001 (Akt activation preserves cardiac function and prevents cardiomyocyte
injury after transient cardiac ischemia in vivo); Miao et al., J Mol Cell Cardiol, 32:2397,
2000 (Intracoronary, adenovirus-mediated Akt gene delivery in heart reduced gross
infarct size following ischemia-reperfusion injury in vivo); and Fujio et al., Circulation et
al., 101:660, 2000 (Akt signaling inhibits cardiac myocyte apoptosis in vitro and protects
against ischemia-reperfusion injury in mouse heart).
[0028] GSK-3 activity plays a role in head trauma. See Noshita et al., Neurobiol Dis,
9:294,2002 (Upregulation of Akt/PI3-kinase pathway may be crucial for cell survival
after traumatic brain injury) and Dietrich et al., J Neurotrauma, 13:309,1996
(Posttraumatic administration of bFGF significantly reduced damaged cortical neurons &
total contusion volume in a rat model of traumatic brain injury).
[0029] GSK-3 is also known to play a role in psychiatric disorders. See Eldar-
Finkelman, Trends Mol Med, 8:126,2002; Li et al., Bipolar Disord, 4:137,2002 (LiCl
and Valproic acid, anti-psychotic, mood stabilizing drugs, decrease GSK3 activities and
increase beta-catenin) and Lijam et al., Cell, 90:895,1997 (Dishevelled KO mice showed
abnormal social behavior and defective sensorimotor gating. Dishevelled, a cytoplamic
protein involved in WNT pathway, inhibits GSK3beta activities).
[0030] It has been shown that GSK3 inhibition by lithium and valproic acid induces
axonal remodeling and change synaptic connectivity. See Kaytor & Orr, Curr Opin
Neurobiol, 12:275, 2002 (Downregulation of GSK3 causes changes in mirotubule-
associated proteins: tau, MAPI & 2) and Hall et al., Mol Cell Neurosci, 20:257, 2002
(Lithium and valproic acid induces the formation of growth cone-like structures along the
axons).
[0031] GSK-3 activity is also associated with Alzheimer"s disease. This disease is
characterized by the presence of the well-known ß-amyloid peptide and the formation of
intracellular neurofibrillary tangles. The neurofibrillary tangles contain
hyperphosphorylated Tau protein, in which Tau is phosphorylated on abnormal sites.

GSK-3 has been shown to phosphorylate these abnormal sites in cell and animal models.
Furthermore, inhibition of GSK-3 has been shown to prevent hyperphosphorylation of
Tau in cells [Lovestone et al., Curr. Biol, 4, 1077-86 (1994); and Brownlees et al.,
Neuroreport 8,3251-55 (1997); Kaytor and Orr, Curr. Opin. Neurobiol., 12, 275-8
(2000)]. In transgenic mice overexpressing GSK3, significant increased Tau
hyperphosphorylation and abnormal morphology of neurons were observed [Lucas et al.,
EMBO J, 20:27-39 (2001)]. Active GSK3 accumulates in cytoplasm of pretangled
neurons, which can lead to neurofibrillary tangles in brains of patients with AD [Pei et al.,
J Neuropathol Exp Neurol, 58, 1010-19 (1999)]. Therefore, inhibition of GSK-3 slows or
halts the generation of neurofibrillary tangles and thus treats or reduces the severity of
Alzheimer"s disease.
[0032] Evidence for the role GSK-3 plays in Alzheimer"s disease has been shown in
vitro. See Aplin et al (1996), J Neurochem 67:699; Sun et al (2002), Neurosci Lett
321:61 (GSK3b phosphorylates cytoplasmic domain of Amyloid Precursor Protein (APP)
and GSK3b inhibition reduces Ab40 & Ab42 secretion in APP-transfected cells);

al., J Neurosci, 23:4499,2003 (The mutations in Alzheimer"s presenilin 1 may deregulate
and increase GSK-3 activity, which in turn, impairs axonal transport in neurons. The
consequent reductions in axonal transport in affected neurons can ultimately lead to
neurodegeneration).
-10-
[0033] Evidence for the role GSK-3 plays in Alzheimer"s disease has been shown in
vivo. See Yamaguchi et al (1996), Acta Neuropathol 92:232; Pei et al (1999), J
Neuropath Exp Neurol 58:1010 (GSK3b immunoreactivity is elevated in susceptible
regions of AD brains); Hernandez et al (2002), J Neurochem 83:1529 (Transgenic mice
with conditional GSK3b overexpression exhibit cognitive deficits similar to those in
transgenic APP mouse models of AD); De Ferrari et al (2003) Mol Psychiatry 8:195
(Chronic lithium treatment rescued neurodegeneration and behavioral impairments
(Morris water maze) caused by intrahippocampal injection of Ab fibrils.); McLaurin et
al., Nature Med, 8:1263,2002 (Immunization with Ab in a transgenic model of AD
reduces both AD-like neuropathology and the spatial memory impairments); and Phiel et
al (2003) Nature 423:435 (GSK3 regulates amyloid-beta peptide production via direct
inhibition of gamma secretase in AD tg mice).
[0034] Presenilin-1 and kinesin-1 are also substrates for GSK-3 and relate to another
mechanism for the role GSK-3 plays in Alzheimer"s disease, as was recently described by
Pigino, G., et al., Journal of Neuroscience (23:4499,2003). It was found that GSK3beta
phosphorylates ldnsesin-I light chain, which results in a release of kinesin-1 from
membrane-bound organelles, leading to a reduction in fast anterograde axonal transport
(Morfmi et al., 2002). The authors suggest that the mutations in PS1 may deregulate and
increase GSK-3 activity, which in turn, impairs axonal transport in neurons. The
consequent reductions in axonal transport in affected neurons ultimately lead to
neurodegeneration.
[0035] GSK-3 is also associated with amyotrophic lateral sclerosis (ALS). See
Williamson and Cleveland, 1999 (Axonal transport is retarded in a very early phase of
ALS in mSOD1 mice); Morfini et al., 2002 (GSK3 phosphorylates kinesin light chains
and inhibit anterograde axonal transport); Warita et al., Apoptosis, 6:345,2001 (The
majority of spinal motor neurons lost the immunoreactivities for both PI3-K and Akt in
the early and presymptomatic stage that preceded significant loss of the neurons in this
SOD1 tg animal model of ALS); and Sanchez et al., 2001 (The inhibition of PI-3K
induces neurite retraction mediated by GSK3 activation).
[0036] GSK-3 activity is also linked to spinal cord and peripheral nerve injuries. It
has been shown that GSK3 inhibition by lithium and valproic acid can induce axonal
remodeling and change synaptic connectivity. See Kaytor & Orr, Curr Opin Neurobiol,

12:275,2002 (Downregulation of GSK3 causes changes in mirotubule-associated
proteins: tau, MAP1 & 2) and Hall et al., Mol Cell Neurosci, 20:257, 2002 (Lithium and
valproic acid induces the formation of growth cone-like structures along the axons). See
also Grothe et al., Brain Res, 885:172, 2000 (FGF2 stimulate Schwann cell proliferation
an inhibit myelination during axonal growth); Grothe and Nikkhah, 2001 (FGF-2 is up
regulated in the proximal and distal nerve stumps within 5 hours after nerve crush); and
Sanchez et al., 2001 (The inhibition of PI-3K induces neurite retraction mediated by
GSK3 activation).
[0037] Another substrate of GSK-3 is p-catenin, which is degraded after
phosphorylation by GSK-3. Reduced levels of P-catenin have been reported in
schizophrenic patients and have also been associated with other diseases related to
increase in neuronal cell death [Zhong et al., Nature, 395, 698-702 (1998); Takashima et
al., PNAS, 90,7789-93 (1993); Pei et al., J. Neuropathol. Exp, 56,70-78 (1997); and
Smith et al., Bio-org. Med. Chem. 11,635-639 (2001)]. Furthermore, ß-catenin and Tcf-4
play a dual role in vascular remodeling by inhibiting vascular smooth muscle cell
apoptosis and promoting proliferation (Wang et al., Circ Res, 90:340,2002).
Accordingly, GSK-3 is associated with angiogenic disorders. See also Liu et al., FASEB
J, 16:950,2002 (Activation of GSK3 reduces hepatocyte growth factor, leading to altered
endothelial cell barrier function and diminished vascular integrity) and Kim et al. K J Biol
Chem, 277:41888,2002 (GSK3beta activation inhibits angiogenesis in vivo using
Matrigel plug assay: the inhibition of GSK3beta signaling enhances capillary formation).
[0038] Association between GSK-3 and Huntington"s disease has been shown. See
Carmichael et al., J Biol Chem., 277:33791,2002 (GSK3beta inhibition protect cells from
poly-glutamine-induced neuronal and non-neuronal cell death via increases in b-catenin
and its associated transcriptional pathway). Overexpression of GSK3 reduced the
activation of heat shock transcription factor-1 and heat shock protein HSP70 (Bijur et al-,
J Biol Chem, 275:7583, 2000) that are shown to decrease both poly-(Q) aggregates and
cell death in in vitro HD model (Wyttenbach eta 1., Hum Mol Genet, 11:1137,2002).
[0039] GSK-3 effects the levels of FGF-2 and their receptors are increased during
remyelination of brain aggregate cultures remyelinating rat brains. See Copelman et al.,
2000, Messersmith, et al., 2000; and Hinks and Franklin, 2000. It was also found that
FGF-2 induces process outgrowth by oligodendrocytes implicating involvement of FGF
in remyelination (Oh and Yong, 1996; Gogate et al., 1994) and that FGF-2 gene therapy
has shown to improve the recovery of experimental allergic encephalomyelitis (EAE)
mice (Ruffini, et al., 2001).
[0040] GSK-3 has also been associated with hair growth because Wnt/beta-catenin
signaling is shown to play a major role in hair follicle morphogenesis and differentiation
(Kishimotot et al. Genes Dev, 14:1181,2000; Millar, J Invest Dermatol, 118:216,2002).
It was found that mice with constitutive overexpression of the inhibitors of Wnt signaling
in skin failed to develop hair follicles. Wnt signals are required for the initial
development of hair follicles and GSK3 constitutively regulates Wnt pathways by
inhibiting beta-catenin. (Andl et al., Dev Cell 2:643,2002). A transient Wnt signal
provides the crucial initial stimulus for the start of a new hair growth cycle, by activating
beta-catenin and TCP-regulated gene transcription in epithelial hair follicle precursors
(Van Mater et al., Genes Dev, 17:1219,2003)
[0041] Because GSK-3 activity, is associated with sperm motility, GSK-3 inhibition is
useful as a male contraceptive. It was shown that a decline in sperm GSK3 activity is
associated with sperm motility development in bovine and monkey epididymis
(Vijayaraghavan et al., Biol Reprod, 54: 709,1996; Smith et al., J Androl, 20:47,1999).
Furthermore, tyrosine & serine/threonine phosphorylation of GSK3 is high in motile
compared to immotile sperm in bulls (Vijayaraghavan et al., Biol Reprod, 62:1647,
2000). This effect was also demonstrated with human sperm (Luconi et al., Human
Reprod, 16:1931,2001).
[0042] The Tec family of non-receptor tyrosine kinases plays a central role in
signalling through antigen-receptors such as the TCR, BCR and Fee receptors (reviewed
in Miller A, et al. Current Opinion in Immunology 14;331-340 (2002). Tec family
kinases are essential for T cell activation. Three members of the Tec family, Itk, Rlk and
Tec, are activated downstream of antigen receptor engagement in T cells and transmit
signals to downstream effectors, including PLC-g. Combined deletion of Itk and Rlk in
mice leads to a profound inhibition of TCR responses including proliferation, cytokine
production and immune responses to an intracellular parasite (Toxoplasma gondii)
(Schaeffer et al, Science 284; 638-641 (1999)). Intracellular signalling following TCR
engagement is effected in Itk/Rlk deficient T cells; inositol triphosphate production,
calcium mobilization and MAP kinase activation are all reduced.

[0043] Tec family kinases are also essential for B cell development and activation.
Patients with mutations in Btk have a profound block in B cell development, resulting in
the almost complete absence of B lymphocytes and plasma cells, severely reduced Ig
levels and a profound inhibition of humoral response to recall antigens (reviewed in
Vihanan et al Frontiers in Bioscience 5:d917-928). Mice deficient in Btk also have a
reduced number of peripheral B cells and greatly decreased levels of IgM and IgG3. Btk
deletion in mice has a profound effect on B cell proliferation induced by anti-IgM, and
inhibits immune responses to thymus-independent type II antigens (Ellmeier et al, J Exp
Med 192:1611-1623 (2000)). Btk also plays a crucial role in mast cell activation through
the high-affinity IgE receptor (FceRI). Btk deficient murine mast cells have reduced
degranulation and decreased production of proinfllammatory cytokines following FceRI
cross-linking (Kawakami et al. Journal of leukocyte biology 65:286-290).
[0044] The ribosomal protein kinases p70S6K-l and -2 are members of the AGC sub-
family of protein kinases that consists of, amongst others, PKB and MSK. The p70S6
kinases catalyze the phosphorylation and subsequent activation of the ribosomal protein
S6, which has been implicated in the translational up-regulation of mRNAs coding for the
components of the protein synthetic apparatus.
[0045] These mRNAs contain an oligopyrimidine tract at their 5" transcriptional start
site, termed a 5TOP, which has been shown to be essential for their regulation at the
translational level (Volarevic, S. et al., Prog. Nucleic Acid Res. Mol. Biol. 2001,65,101-
186). p70 S6K dependent S6 phosphorylation is stimulated in response to a variety of
hormones and growth factors primarily via the PI3K pathway (Coffer, P.J. et al.,
Biochem. Biophys. Res. Commun, 1994 198,780-786), which maybe under the regulation
of mTOR, since rapamycin acts to inhibit p70S6K activity and blocks protein synthesis,
specifically as a result of a down-regulation of translation of these mRNA"s encoding
ribosomal proteins (Kuo, C.J. et al., Nature 1992,358,70-73).
[0046] In vitro PDK1 catalyses the phosphorylation of Thr252 in the activation loop of
the p70 catalytic domain, which is indispensable for p70 activity (Alessi, D.R., Curr.
Biol., 1998, S, 69-81). The use of rapamycin and gene deletion studies,of dp70S6K from
Drosophila and p70S6Kl from mouse have established the central role p70 plays in both
cell growth and proliferation signaling.

[0047] The 3-phosphoinositide-dependent protein kinase-1 (PDKl) plays a key role in
regulating the activity of a number of kinases belonging to the AGC subfamily of protein
kinases (Alessi, D. et al., Biockem. Soc. Trans 2001,29,1). These include isoforms of
protein kinase B (PKB, also known as AKT), p70 ribosomal S6 kinase (S6K) (Avruch, J.
et al., Prog. Mol. Subcell. Biol 2001,26,115), and p90 ribosomal S6 kinase (Frödin, M.
et al., EMBO J. 2000,19, 2924-2934). PDK1 mediated signaling is activated in response
to insulin and growth factors and as a consequence of attachment of the cell to the
extracellular matrix (integrin signaling). Once activated these enzymes mediate many
diverse cellular events by phosphorylating key regulatory proteins that play important
roles controlling processes such as cell survival, growth, proliferation and glucose
regulation [(Lawlor, M.A. et al., J. Cell Sci. 2001, 114,2903-2910), (Lawlor, M.A. et al.,
EMBO J. 2002,21,3728-3738)]. PDK1 is a 556 amino acid protein, with an N-terminal
catalytic domain and a C-terminal pleckstrin homology (PH) domain, which activates its
substrates by phosphorylating these kinases at their activation loop (Belham, C. et al.,
Curr. Biol. 1999,9, R93-R96). Many human cancers including prostate and NSCL have
elevated PDK1 signaling pathway function resulting from a number of distinct genetic
events such as PTEN mutations or over-expression of certain key regulatory proteins
[(Graff, J.R., Expert Opin. Ther. Targets 2002, 6,103-113), (Brognard, J., et al., Cancer
Res. 2001, 61,3986-3997)]. Inhibition of.PDKl as a potential mechanism to treat cancer
was demonstrated by transfection of a PTEN negative human cancer cell line (U87MG)
with antisense oligonucleotides directed against PDK1. The resulting decrease in PDKl
protein levels led to a reduction in cellular proliferation and survival (Flynn, P., et al.,
Curr. Biol. 2000,10, 1439-1442). Consequently the design of ATP binding site inhibitors
of PDKl offers, amongst other treatments, an attractive target for cancer chemotherapy.
[0048] The diverse range of cancer cell genotypes has been attributed to the
manifestation of the following six essential alterations in cell physiology: self-sufficiency
in growth signaling, evasion of apoptosis, insensitivity to growth-inhibitory signaling,
limitless replicative potential, sustained angiogenesis, and tissue invasion leading to
metastasis (Hanahan, D. et al., Cell 2000,100, 57-70). PDKl is a critical mediator of the
PI3K signalling pathway, which regulates a multitude of cellular function including
growth, proliferation and survival. Consequently, inhibition of this pathway could affect
four or more of the six defining requirements for cancer progression. As such it is

anticipated that a PDK1 inhibitor will have an effect on the growth of a very wide range
of human cancers.
[0049] Specifically, increased levels of PI3K pathway activity has been directly
associated with the development of a number of human caners, progression to an
aggressive refractory state (acquired resistance to chemotherapies) and poor prognosis.
This increased activity has been attributed to a series of key events including decreased
activity of negative pathway regulators such as the phosphatase PTEN, activating
mutations of positive pathway regulators such as Ras, and overexpression of components
of the pathway itself such as PKB, examples include: brain (gliomas), breast, colon, head
and neck, kidney, lung, liver, melanoma, ovarian, pancreatic, prostate, sarcoma, thyroid
[(Teng, D.H. et al, Cancer Res., 1997 57,5221-5225), (Brognard, J. et al., Cancer Res.,
2001,61, 3986-3997), (Cheng, J.Q. et al., Proc. Nati. Acad. Sci. 1996,93, 3636-3641),
(Int. J. Cancer 1995, 64, 280), (Graff, 3.R., Expert Opin. Ther. Targets 2002,6,103-113),
(Am. J. Pathol. 2001,159,431)].
[0050] Additionally, decreased pathway function through gene knockout, gene
knockdown, dominant negative studies, and small molecule inhibitors of the pathway
have been demonstrated to reverse many of the cancer phenotypes in vitro (some studies
have also demonstrated a similar effect in vivo) such as block proliferation, reduce
viability and sensitize cancer cells to known chemotherapies in a series of cell lines,
representing the following cancers: pancreatic [(Cheng, J.Q. et al., Proc. Natl. Acad. Sci.
1996,93,3636-3641), (Neoplasia 2001,3,278)], lung [(Brognard, J. et al., Cancer Res.
2001,61, 3986-3997), (Neoplasia 2001,3,278)], ovarian [(Hayakawa, J. et al, Cancer
Res. 2000,60, 5988-5994), (Neoplasia 2001, 3, 278)], breast (Mol. Cancer Ther. 2002,1,
707), colon [(Neoplasia 2001,3, 278), (Arico, S. etal., J. Biol. Chem. 2002,277,27613-
27621)], cervical (Neoplasia 2001, 3,278), prostate [(Endocrinology 2001,142,4795),
(Thakkar, H. et al. J. Biol. Chem. 2001,276,38361-38369), (Chen, X. et al., Oncogens
2001,20, 6073-6083)] and brain (glioblastomas) [(Flynn, P. etal, Curr. Biol. 2000,10,
1439-1442)].
[0051] The Aurora family of serine/threonine kinases is essential for cell proliferation
[Bischoff, J.R. & Plowman, G.D. (The Aurora/Ip11p kinase family: regulators of
chromosome segregation and cytokinesis) Trends in Cell Biology 9,454-459 (1999);
Giet, R. and Prigent, C. (Aurora/Ip11p-related kinases, a new oncogenic family of mitotic

serine-threonine kinases) Journal of Cell Science 112, 3591-3601 (1999); Nigg, E.A.
(Mitotic kinases as regulators of cell division and its checkpoints) Nat. Rev. Mol. Cell
Biol. 2,21-32 (2001); Adams, R. R, Carmena, M., and Earnshaw, W.C. (Chromosomal
passengers and the (aurora) ABCs of mitosis) Trends in Cell Biology 11,49-54 (2001)].
Inhibitors of the Aurora kinase family therefore have the potential to block growth of all
tumour types.
[0052] The three known mammalian family members, Aurora-A ("1"). B ("2") and C
("3"), are highly homologous proteins responsible for chromosome segregation, mitotic
spindle function and cytokinesis. Aurora expression is low or undetectable in resting
cells, with expression and activity peaking during the G2 and mitotic phases in cycling
cells. In mammalian cells proposed substrates for Aurora include histone H3, a protein
involved in chromosome condensation, and CENP-A, myosin II regulatory light chain,
protein phosphatase 1, TPX2, all of which are required forcell division.
[0053] Since its discovery in 1997 the mammalian Aurora kinase family has been
closely linked to tumorigenesis. The most compelling evidence for this is that over-
expression of Aurora-A transforms rodent fibroblasts (Bischoff, J. R., et al. A homologue
of Drosophila aurora kinase is oncogenic and amplified in human colorectal cancers.
EMBO J. 17, 3052-3065 (1998)). Cells with elevated levels of this kinase contain
multiple centrosomes and multipolar spindles, and rapidly become aneuploid. The
oncogenic activity of Aurora kinases is likely to be linked to the generation of such
genetic instability. Indeed, a correlation between amplification of the aurora-A locus and
chromosomal instability in mammary and gastric tumours has been observed. (Miyoshi,
Y., Iwao, K., Egawa, C, and Noguchi, S. Association of centrosomal kinase
STK15/BTAK mRNA expression with chromosomal instability in human breast cancers.
Int. J. Cancer 92,370-373 (2001). (Sakakura, C. et al. Tumor-amplified kinase BTAK is
amplified and overexpressed in gastric cancers with possible involvement in aneuploid
formation. British Journal of Cancer 84, 824-831 (2001)).". The Aurora kinases have
been reported to be over-expressed in a wide range of human tumours. Elevated
expression of Aurora-A has been detected in over 50% of colorectal (Bischoff, J. R., et al.
A homologue of Drosophila aurora kinase is oncogenic and amplified in human
colorectal cancers. EMBO J. 17,3052-3065 (1998)) (Takahashi, T., et al. Centrosomal
kinases, HsAIRkl and HsAIRK3, are overexpressed in primary colorectal cancers. Jpn.

J. Cancer Res. 91,1007-1014 (2000)). ovarian (Gritsko, T.M. et al. Activation and
overexpression of centrosome kinase BTAK/Aurora-A in human ovarian cancer. Clinical
Cancer Research 9,1420-1426 (2003)), and gastric tumors (Sakakura, C. et al. Tumor-
amplified kinase BTAK is amplified and overexpressed in gastric cancers with possible
involvement in aneuploid formation. British Journal of Cancer 84, 824-831 (2001)), and
in 94% of invasive duct adenocarcinomas of the breast (Tanaka, T., et al. Centrosomal
kinase AIK1 is overexpressed in invasive ductal carcinoma of the breast. Cancer
Research. 59,2041-2044 (1999)). High levels of Aurora-A have also been reported in
renal, cervical, neuroblastoma, melanoma, lymphoma, pancreatic and prostate tumour cell
lines. (Bischoff, J. R., et al. A homologue of Drosophila aurora kinase is oncogenic and
amplified in human colorectal cancers. EMBO J. 17,3052-3065 (1998) (Kimura, M.,
Matsuda, Y., Yoshioka, T., and Okano, Y. Cell cycle-dependent expression and
centrosomal localization of a third human Aurora/Ip11-related protein kinase, AIK3.
Journal of Biological Chemistry 274,7334-7340 (1999))(Zhou et al. Tumour amplifiec
kinase STK15/BTAK induces centrosome amplification, aneuploidy and transformation
Nature Genetics 20: 189-193 (1998))(Li et al. Overexpression of oncogenic
STK15/BTAK/Aurora-A kinase in human pancreatic cancer Clin Cancer Res. 9(3):991-7
(2003)). Amplification/overexpression of Aurora-A is observed in human bladder
cancers and amplification of Aurora-A is associated with aneuploidy and aggressive
clinical behaviour (Sen S. et al Amplification/overexpression of a mitotic kinase gene in
human bladder cancer JNatl Cancer Inst. 94(17): 1320-9 (2002)). Moreover,
amplification of the aurora-A locus (20q13) correlates with poor prognosis for patients
with node-negative breast cancer (Isola, J. J., et al. Genetic aberrations detected by
comparative genomic hybridization predict outcome in node-negative breast cancer.
American Journal of Pathology 147,905-911 (1995)).. Aurora-B is highly expressed in
multiple human tumour cell lines, including leukemic cells (Katayama et al. Human
AIM-1: cDNA cloning and reduced expression during endomitosis in megakaryocyte-
lineage cells. Gene 244:1-7)). Levels of this enzyme increase as a function of Duke"s
stage in primary colorectal cancers (Katayama, H. et al. Mitotic kinase expression and
colorectal cancer progression. Journal of the National Cancer Institute 91,1160-1162
(1999)). Aurora-C, which is normally only found in germ cells, is also over-expressed in
a high percentage of primary colorectal cancers and in a variety of tumour cell lines

including cervical adenocarinoma and breast carcinoma cells (Kimura, M., Matsuda, Y.,
Yoshioka, T., and Okano, Y. Cell cycle-dependent expression and centrosomal
localization of a third human Aurora/Ip11-related protein kinase, AIK3. Journal of
Biological Chemistry 21 A, 7334-7340 (1999). (Takahashi, T., et al. Centrosomal kinases,
HsAIRk1 and HsAIRK3, are overexpressed in primary colorectal cancers. Jpn. J. Cancer
Res. 91,1007-1014 (2000)).
[0054] Based on the known function of the Aurora kinases, inhibition of their activity
should disrupt mitosis leading to cell cycle arrest. In vivo, an Aurora inhibitor therefore
slows tumor growth and induces regression.
[0055] Elevated, levels of all Aurora family members are observed in a wide variety of
tumour cell lines. Aurora kinases are over-expressed in many human tumors and this is
reported to be associated with chromosomal instability in mammary tumors (Miyoshi et al
2001 92,370-373).
[0056] Aurora-2 is highly expressed in multiple human tumor cell lines and levels
increase as a function of Duke"s stage in primary colorectal cancers [Katayama, H. et al.
(Mitotic kinase expression and colorectal cancer progression) Journal of the National
Cancer Institute 91, 1160-1162 (1999)]. Aurora-2 plays a role in controlling the accurate
segregation of chromosomes during mitosis. Misregulation of the cell cycle can lead to
cellular proliferation and other abnormalities. In human colon cancer tissue, the Aurora-2
protein is over expressed [Bischoff et al., EMBO J., 17, 3052-3065 (1998); Schumacher et
al., J. Cell Biol., 143,1635-1646 (1998); Kimura et al., J. Biol. Chem., 272, 13766-13771
(1997)]. Aurora-2 is over-expressed in the majority of transformed cells. Bischoff et al
found high levels of Aurora-2 in 96% of cell lines derived from lung, colon, renal,
melanoma and breast tumors (Bischoff et al EMBO J. 1998 17, 3052-3065). Two
extensive studies show elevated Aurora-2 in 54% and 68% (Bishoff et al EMBO J. 1998
17,3052-3065)(Takahashi et al 2000 Jpn J Cancer Res. 91, 1007-1014) of colorectal
tumours and in 94% of invasive duct adenocarcinomas of the breast (Tanaka et al 1999
59, 2041-2044).
[0057] Aurora-1 expression is elevated in cell lines derived from tumors of the colon,
breast, lung, melanoma, kidney, ovary, pancreas, CNS, gastric tract and leukemias
(Tatsukaetal 1998 58,4811-4816).

[0058] High levels of Aurora-3 have been detected in several tumour cell lines,
although it is restricted to testis in normal tissues (Kimura et al 1999 274,7334-7340).
Over-expression of Aurora-3 in a high percentage (c. 50%) of colorectal cancers has also
been documented (Takahashi et al 2000 Jpn J Cancer Res. 91,1007-1014). In contrast,
the Aurora family is expressed at a low level in the majority of normal tissues, the
exceptions being tissues with a high proportion of dividing cells such as the thymus and
testis (Bischoff et al EMBO J. 1998 17,3052-3065).

[0060] The type III receptor tyrosine kinase, Flt3, plays an important role in the
maintenance, growth and development of hematopoietic and non-hematopoietic cells.
[Scheijen, B, Griffin JD; Oncogene, 2002, 21, 3314-3333 and Reilly, JT, British Journal
of Haematology, 2002,116,744-757]. FLT-3 regulates maintenance of stem cell/early
progenitor pools as well the development of mature lymphoid and myeloid cells [Lyman,
S, Jacobsen, S, Blood, 1998,91,1101-1134]. FLT-3 contains an intrinsic kinase domain
that is activated upon ligand-mediated dimerization of the receptors. Upon activation, the
kinase domain induces autophosphorylation of the receptor as well as the phosphorylation
of various cytoplasmic proteins that help propogate the activation signal leading to
growth, differentiation and survival. Some of the downstream regulators of FLT-3
receptor signaling include, PLC?, PI3-kinase, Grb-2, SHIP and Src related kinases
[Scheijen, B, Griffin JD, Oncogene, 2002,21,3314-3333]. FLT-3 kinase plays a role in a
variety of hematopoietic and non-hematopoietic malignancies. Mutations that induce
ligand independent activation of FLT-3 have been implicated in acute-myelogenous
leukemia (AML), acute lymphocytic leukemia (ALL), mastocytosis and gastrointestinal

stromal tumor (GIST). These mutations include single amino acid changes in the kinase
domain or internal tandem duplications, point mutations or in-frame deletions of the
juxtamernbrane region of the receptors. In addition to activating mutations, Iigand
dependent (autocrine or paracrine) stimulation of over-expressed wild-type FLT-3
contributes to the malignant phenotype [Scheijen, B, Griffin JD, Oncogene, 2002,21,
3314-3333]. See also Sawyer, C.l. (Finding the next Gleevec: FLT3 targeted kinase
inhibitor therapy for acute myeloid leukaemia) Cancer Cell.l, 413-415 (2002).
[0061] Cyclin-dependent kinases (CDKs) are serine/threonine protein kinases
consisting of a b-sheet rich amino-terminal lobe and a larger carboxy-terminal lobe that is
largely a-helical. The CDKs display the 11 subdomains shared by all protein kinases and
range in molecular mass from 33 to 44 kD. This family of kinases, which includes
CDK1, CKD2, CDK4, and CDK6, requires phosphorylation at the residue corresponding
to CDK2 Thrl60 in order to be fully active [Meijer, L., Drug Resistance Updates 2000,3,
83-88].
[0062] Each CDK complex is formed from a regulatory cyclin subunit (e.g., cyclin A,
B1, B2, D1, D2, D3, and E) and a catalytic kinase subunit (e.g., CDK1, CDK2, CDK4,
CDK5, and CDK6). Each different kinase/cyclin pair functions to regulate the different
and specific phases of the cell cycle known as the G1, S, G2, and M phases [Nigg, E.,
Nature Reviews 2001,2,21-32; Flatt, P., Pietenpol, J., Drug Metabolism Reviews 2000,
32,283-305].
[0063] The CDKs have been implicated in cell proliferation disorders, particularly in
cancer. Cell proliferation is a result of the direct or indirect deregulation of the cell
division cycle and the CDKs play a critical role in the regulation of the various phases of
this cycle. For example, the over-expression of cyclin Dl is commonly associated with
numerous human cancers including breast, colon, hepatocellular carcinomas and gliomas
[Flatt, P., Pietenpol, J., Drug Metabolism Reviews 2000,32,283-305]. The CDK2/cyclin
E complex plays a key role in the progression from the early Gl to S phases of the cell
cycle and the overexpression of cyclin E has been associated with various solid tumors.
Therefore, inhibitors of cyclins Dl, E, or their associated CDKs are useful targets for
cancer therapy [Kaubisch, A., Schwartz, G., The Cancer Journal 2000,6, 192-212].
[0064] CDKs, especially CDK2, also play a role in apoptosis and T-cell development.
CDK2 has been identified as a key regulator of thymocyte apoptosis [Williams, O., et al,

European Journal of Immunology 2000,709-713]. Stimulation of CDK2 kinase activity
is associated with the progression of apoptosis in thymocytes, in response to specific
stimuli. Inhibition of CDK2 kinase activity blocks this apoptosis resulting in the
protection of thymocytes.
[0065] In addition to regulating the cell cycle and apoptosis, the CDKs are directly
involved in the process of transcription. Numerous viruses require CDKs for their
replication process. Examples where CDK inhibitors restrain viral replication include
human cytomegalovirus, herpes virus, and varicella-zoster virus [Meijer, L., Drug
Resistance Updates 2000,3, 83-88].
[0066] Inhibition of CDK is also useful for the treatment of neurodegenerative
disorders such as Alzheimer"s disease. The appearance of Faired Helical Filaments
(PHF), associated with Alzheimer"s disease, is caused by the hyperphosphorylation of Tau
protein by CDK5/p25 [Meijer, L., Drug Resistance Updates, 2000 3, 83-88].
[0067] PIM-1 is the protooncogene activated by murine leukemia virus (Provirus
Integration site for Moloney murine leukemia virus) [Cuypers, H.T. et al. Cell 1984,37,
141—150]. The expression of the protoconcogene produces a non-transmembrane
serine/threonine kinase of 313 residues, including a kinase domain consisting of 253
amino acid residues. Two isofonns are known through alternative initiation (p44 and
p33) [Saris, C.J.M. ettd., EMBO J. 1991,10, 655-664]. Two PIM-1 homologs have been
described [Baytel, D. Biochim Biophys Acta 1998,1442, 274-85; Feldman, J. etal.J
Biol Chem 1998,273,16535-16543]. PIM-2 and PIM-3 are respectively 58% and 69%
identical to Pim-1 at the amino acid level. PIM-1 is highly expressed in the liver and
spleen during hematopoiesis, and expression is induced by cytokines such as GM-CSF,
G-SCF, IL-3, IF-a, and IL-6 [Lilly, M. et al., Oncogene 1992, 7,727-732; Sato, N. et al,
EMBO J. 1993,12,4181-4189; Jaster, R. et al., Cell Signal 1999,11, 331-335;
Matikainen, S. et al, Blood 1999,93,1980-1991].
[0068] PIM-1 has been implicated in lymphoma development. Induced expression of
PIM-1 and the protooncogene c-myc synergize to increase the incidence of
lymphomagenesis [Breuer, M. et al., Nature 1989, 340,61-63; van Lohuizen, M. et al.,
Cell 1991, 65,737-52]. PIM-1 functions in cytokine signaling pathways and has been
shown to play a role in T-cell development [Schmidt, T. et al, EMBO J. 17,1998,5349-
5359; Jacobs, H. et al., JEM 1999,190,1059-1068]. Signaling through gpl30, a subunit

common to receptors of the IL-6 cytokine family, activates the transcription factor
STAT3 and can lead to the proliferation of hematopoietic cells [Hirano, T. et al,
Oncogene 2000,19,2548-2556]. A kinase-active P1M-1 appears to be essential for the
gpl30-mediated STAT3 proliferation signal. In cooperation with the c-myc, PIM-1 can
proteste STAT3-mediated cell cycle progression and antiapoptosis [Shirogane, T. et al,
Immunity 1999,11,709-719]. PIM-1 also appears to be necessary for IL-3-stimulated
growth in bone marrow- derived mast cells [Domen, J. et al, Blood 1993,82,1445-52]
and survival of FDCP1 cells after IL-3 withdrawal [Lilly, M. et al, Oncogene 1999,18,
4022-4031].
[0069] Additionally, control of cell proliferation and survival by PIM-1 may be
effected by means of its phosphorylation of the well established cell cycle regulators
cdc25 [Mochizuki, T. et al., J. Biol. Chem. 1999,274,18659-18666] and/or
p21(Cip1/WAF1)[ Wang, Z. et al., Biochim. Biophys. Acta 2002,1593,45-55] or
phosphorylation of heterochromatin protein 1, a molecule involved in chromatin structure
and transcriptional regulation [Koike, N. et al, FEBS Lett. 2000,467,17-21].
[0070] A family of type m receptor tyrosine kinases including Flt3, c-Kit, PDGF-
receptor and c-Fms play an important role in the maintenance, growth and development
of hematopoietic and non-hematopoietic cells. [Scheijen, B, Griffin JD, Oncogene, 2002,
21, 3314-3333 and Reilly, JT, British Journal of Haematology, 2002,116,744-757].
FLT-3 and c-Kit regulate maintenance of stem cell/early progenitor pools as well the
development of mature lymphoid and myeloid cells [Lyman, S, Jacobsen, S, Blood, 1998,
91, 1101-1134]. Both receptors contain an intrinsic kinase domain that is activated upon
ligand-mediated dimerization of the receptors. Upon activation, the kinase domain
induces autophosphorylation of the receptor as well as the phosphorylation of various
cytoplasmic proteins that help propogate the activation signal leading to growth,
differentiation and survival. Some of the downstream regulators of FLT-3 and c-Kit
receptor signaling include, PLC?, PI3-kinase, Grb-2, SHIP and Src related kinases
[Scheijen, B, Griffin JD, Oncogene, 2002,21, 3314-3333]. Both receptor tyrosine
kinases have been shown to play a role in a variety of hematopoietic and non-
hematopoietic malignancies. Mutations that induce ligand independent activation of
FLT-3 and c-Kit have been implicated acute-myelogenous leukemia (AML), acute
lymphocytic leukemia (ALL), mastocytosis and gastrointestinal stromal tumor (GIST).

These mutations include single amino acid changes in the kinase domain or internal
tandem duplications, point mutations or in-frame deletions of the juxtamembrane region
of the receptors. In addition to activating mutations, ligand dependent (autocrine or
paracrine) stimulation of over-expressed wild-type FLT-3 or c-Kit can contribute to the
mangnant phenotype [Scheijen, B, Griffin JD, Oncogene, 2002,21,3314-3333].
[0071] c-fms encodes for macrophage colony stimulating factor receptor (M-CSF-1R)
which is expressed predominately in the monocytes/macrophage lineage [Dai, XM et al.,
Blood, 2002,99,111-120]. MCSF-1R and its ligand regulate macrophage lineage growth
and differentiation. like the other family members, MCSF-1R contains an intrinsic
kinase domain that is activated upon ligand-induced dimerization of the receptor. MCSF-
1R is is also expressed in non- hematopoietic cells including mammary gland epithelial
cells and neurons. Mutations in this receptor are potentially linked to myeloid leukemias
and its expression is correlated with metastatic breast, ovarian and endometrial
carcinomas [Reilly, JT, British Journal of Haematology, 2002,116,744-757 and
Kacinski, BM, Mol. Reprod and Devel., 1997, 46,71-74]. Another possible indication
for antagonists of MCSF-1R is osteoporosis [Teitelbaum, S, Science 2000, 289,1504-
1508.
[0072] PDGF-receptor (PDGFR) has two subunits- PDGFR-a and PDGRR-ß, which
can form homo or heterodimers upon ligand binding. There are several PDGF ligands:
AB, BB, CC and DD. PDGFR is expressed on early stem cells, mast cells, myeloid cells,
mesenchymal cells and smooth muscle cells [Scheijen, B, Griffin JD, Oncogene, 2002,
21,3314-3333]. Only PDGFR-ß has been implicated in myeloid leukemias- usually as a
translocation partner with Tel, Huntingtin interacting protein (HIP1) or Rabaptin5.
Recently it was shown that activation mutations in PDGFR-a kinase domain are in
gastrointestinal stromal tumors (GIST) [Heinrich, MC et al., Sciencexpress, 2003]
[0073] Another kinase family of particular interest is the Src family of kinases. These
kinases are implicated in cancer, immune system dysfunction and bone remodeling
diseases. For general reviews, see Thomas and Brugge, Annu. Rev. Cell Dev. Biol. 1997,
13, 513; Lawrence and Niu, Pharmacol. Ther. 1998, 77, 81; Tatosyan and Mizenina,
Biochemistry (Moscow) 2000, 65, 49-58; Boschelli et al., Drugs of the Future 2000,
25(7), 717.

[0074] Members of the Src family include the following eight kinases in mammals:
Src, Fyn, Yes, Fgr, Lyn, Hck, Lck, and Blk. These are nonreceptor protein kinases that
range in molecular mass from 52 to 62 kD. All are characterized by a common structural
organization that is comprised of six distinct functional domains: Src homology domain 4
(SH4), a unique domain, SH3 domain, SH2 domain, a catalytic domain (SHI), and a C-
tenninal regulatory region. Tatosyan et al. Biochemistry (Moscow) 2000,65,49-58.
[0075] Based on published studies, Src kinases are considered as potential therapeutic
targets for various human diseases. Mice that are deficient in Src develop osteopetrosis,
or bone build-up, because of depressed bone resorption by osteoclasts. This shows that
osteoporosis resulting from abnormally high bone resorption is treated by inhibiting Src.
Soriano et al., Cell 1992,69, 551 and Soriano et al., Cell 1991, 64,693.
[0076] Suppression of arthritic bone destruction has been achieved by the
overexpression of CSK in rheumatoid synoviocytes and osteoclasts. Takayanagi et al., J..
Clin. Invest. 1999,104,137. CSK, or C-terminal Src kinase, phosphorylates and thereby
inhibits Src catalytic activity. This implies that Src inhibition may prevent joint
destruction that is characteristic in patients suffering from rheumatoid arthritis. Boschelli
et al., Drugs of the Future 2000,25(7), 717.
[0077] Src also plays a role in the replication of hepatitis B virus. The virally encoded
transcription factor HBx activates Src in a step required for propagation of the virus.
Klein et al, EMBO J. 1999, IS, 5019, and Klein et al., Mol. Cell. Biol. 1997,17,6427.
[0078] A number of studies have linked Src expression to cancers such as colon,
breast, hepatic and pancreatic cancer, certain B-cell leukemias and lymphomas.
Talamonti et al., J. Clin. Invest. 1993, 91, 53; Lutz et al., Biochem. Biophys. Res. 1998
243, 503; Rosen et al., J. Biol. Chem. 1986, 267,13754; Bolen et al., Proc. Natl Acad.
Sci. USA 1987, 84,2251; Masaki et al, Hepatology 1998, 27,1257; Biscardi et al, Adv.
Cancer Res. 1999, 76,61; Lynch et al, Leukemia 1993, 7,1416. Furthermore, antisense
Src expressed, in ovarian and colon tumor cells has been shown to inhibit tumor growth.
Wiener et al., Clin. Cancer Res., 1999, 5, 2164; Staley et al., Cell Growth Diff. 1997,8,
269.
[0079] Other Src family kinases are also potential therapeutic targets. Lck plays a role
in T-cell signaling. Mice that lack the Lck gene have a poor ability to develop
thyrnocytes. 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. Molina et al., Nature, 1992,357,161. Hck, Fgr and Lyn have been identified as
important mediators of integrin signaling in myeloid leukocytes. Lowell et al, J. Leukoc.
Biol., 1999,65, 313. Inhibition of these kinase mediators may therefore be useful for
treating inflammation. Boschelli et al., Drugs of the Future 2000,25(7), 717.
[0080] Syk is a tyrosine kinase that plays a critical role in FceRI mediated mast cell
degranulation and eosinophil activation. Accordingly, Syk kinase is implicated in various
allergic disorders, in particular asthma. It has been shown that Syk binds to the
phosphorylated gamma chain of the FceRI receptor via N-terminal SH2 domains and is
essential for downstream signaling [Taylor et al, Mol. Cell. Biol. 1995,15,4149].
[0081] Inhibition of eosinophil apoptosis has been proposed as a key mechanism for
the development of blood and tissue eosinophilia in asthma. IL-5 and GM-CSF are
upregulated in asthma and are proposed to cause blood and tissue eosinophilia by
inhibition of eosinophil apoptosis. Inhibition of eosinophil apoptosis has been proposed
as a key mechanism for the development of blood and tissue eosinophilia in asthma. It
has been reported that Syk kinase is requircd foxthe prevention of eosinophil apoptosis by
cytokines (using antisense)[Yousefi et al., J. Exp. Med. 1996,183,1407].
[0082] The role of Syk in FcyR dependent and independent response in bone marrow
derived macrophages has been determined by using irradiated mouse chimeras
reconstituted with fetal liver cells from Syk -/- embryos. Syk deficient macrophages were
defective in phagocytosis induced by Fc?R but showed normal phagocytosis in response
to complement [Kiefer et al, Mol Cell. Biol. 1998,18,4209]. It has also been reported
that aerosolized Syk antisense suppresses Syk expression and mediator release from
macrophages [Stenton et al, J. Immunology 2000,164,3790].
[0083] Another kinase family of interest is Rho-associated coiled-coil forming protein
serine/threonine kinase (ROCK), which is believed to be an effector of Ras-related small
GTPase Rho. The ROCK family includes p160ROCK (ROCK-1) (Ishizaki et al, EMBO
J. 1996,15,1885-1893) and ROKa/Rho-kinase/ROCK-II (Leung et al., J. Biol. Chem.
1995,270,29051-29054; Matsui et al, EMBO J. 1996,15,2208-2216; Nakagawa et al,
FEBS Lett. 1996, 392, 189-193), protein kinase PKN (Amano et al, Science 1996,271,
648-650; Watanabe et al., Science 1996, 271, 645-648), and citron and citron kinase
(Madaule et al., Nature 1998,394,491-494; Madaule et al., FEBS Lett. 1995,377,243-
248). The ROCK family of kinases have been shown to be involved in a variety of
functions including Rho-induced formation of actin stress fibers and focal adhesions
(Leung et al., Mot. Cell Biol. 1996,16,5313-5327; Amano et al., Science 1997,275,
1308-1311; Ishizaki etal., FEBS Lett. 1997,404,118-124) and in downregulation of
mynsin phosphatase (Kimura et al., Science 1996,273,245-248), platelet activation
(Klages et al, J. Cell Biol. 1999,144,745-754), aortic smooth muscle contraction by
various stimuli (Fu et al., FEBS Lett. 1998,440,183-187), thrombin-induced responses of
aortic smooth muscle cells (Seasholtz et al., dr. Res. 1999,84,1186-1193), hypertrophy
of cardiomyocytes (Kuwahara et al, FEBS Lett., 1999,452,314-318), bronchial smooth
muscle contraction (Yoshii et al.. Am. J. Respir. Cell Mol. Biol. 1999,20,1190-1200),
smooth muscle contraction and cytoskeletal reorganization of non-muscle cells (Fukata et
al. Trends in Pharm. Sci. 2001, 22, 32-39), activation of volume-regulated anion
channels (Nilius et al, J. Physiol. 1999,516,67-74), neurite retraction (Hirose et al., J.
Cell Biol. 1998,141, 1625-1636), neutrophil chemotaxis (Niggli, FEBS Lett. 1999,445,
69-72), wound healing (Nobes and Hall, J. Cell Biol 1999,144,1235-1244), tumor
invasion (Itoh et al., Nat. Med. 1999,5,221-225) and cell transformation (Sahai et al.,
Curr. Biol. 1999,9, 136-145). Accordingly, the development of inhibitors of ROCK
kinase would be useful as therapeutic agents for the treatment of disorders mediated by
the ROCK kinase pathway.
[0084] ZAP-70 is essential for T-cell receptor signalling. Expression of this tyrosine
kinase is restricted to T-cells and natural killer cells. The importance of ZAP-70 in T-cell
function has been demonstrated in human patients, human T-cell lines and mice. Human
patients suffering from a rare form of severe combined deficiency syndrome (SCID)
possess homozygous mutations in ZAP-70 (reviewed in Elder J. of Pedriatric
Hematology/Oncology 1997, iP(6), 546-550). These patients have profound
immunodeficiency, lack CD8+ T-cells and have CD4+ T-cells that are unresponsive to T-
cell receptor (TCR)-mediated stimulation. Following TCR activation these CD4+ cells
show severe defects in Ca2+ mobilization, tyrosine phosphorylation of down-stream
substrates, proliferation and IL-2 production 70 (reviewed in Elder Pedriatric Research
39,743-748). Human Jurkat cells lacking ZAP-70 also provide important insights into
the critical role of ZAP-70 in T-cell receptor signalling. A Jurkat clone (p116) with no
detectable ZAP-70 protein was shown to have defects in T-cell receptor signalling which

could be corrected by re-introduction of wild type ZAP-70 (Williams et al., Molecular
and Cellular Biology 1998,18 (3), 1388-1399). Studies of mice lacking ZAP-70 also
demonstrate a requirement of ZAP-70 in T-cell receptor signalling. ZAP-70-deficient
mice have profound defects in T-cell development and T-cell receptor signalling in
thynrocytes is impaired (Negishi et al., Nature 1995 376,435-438).
[0085] The importance of the kinase domain in ZAP-70 function is demonstrated by
studies of human patients and mice expressing identical mutations in the DLAARN motif
within the kinase domain of ZAP-70. Inactivation of kinase activity by this mutation
results in defective T-cell receptor signalling (Elder et al., J. Immunology 2001, 656-661).
Catalytically inactive ZAP-70 (Lys369Arg) was also defective in restoring T-cell receptor
signalling in a ZAP-70-deficient Jurkat cell clone (pi 16) (Williams et al., Molecular and
Cellular Biology 1998,18 (3), 1388-1399).
[0086] The Janus kinases (JAK) are a family of tyrosine kinases consisting of JAK1,
JAK2, JAK3 and TYK2. The JAKs play a critical role in cytokine signaling. The down-
stream substrates of the JAK family of kinases include the signal transducer and activator
of transcription (STAT) proteins. JAK/STAT signaling has been implicated in the
mediation of many abnormal immune responses such as allergies, asthma, autoimmune
diseases such as transplant rejection, rheumatoid arthritis, amyotrophic lateral sclerosis
and multiple sclerosis as well as in solid and hematologic malignancies such as leukemias
and lymphomas. The pharmaceutical intervention in the JAK/STAT pathway has been
reviewed [Frank Mol. Med. 5:432-456 (1999) & Seidel, et al, Oncogene 19: 2645-2656
(2000)].
[0087] JAK1, JAK2, and TYK2 are ubiquitously expressed, while JAK3 is
predominantly expressed in hematopoietic cells. JAK3 binds exclusively to the common
cytokine receptor gamma chain (?c) and is activated by IL-2, IL-4, IL-7, EL-9, and IL-15.
The proliferation and survival of murine mast cells induced by IL-4 and IL-9 have, in
fact, been shown to be dependent on JAK3- and ?c- signaling [Suzuki et al, Blood 96:
2172-2180(2000)].
[0088] Cross-linking of the high-affinity immunoglobulin (Ig) E receptors of
sensitized mast cells leads to a release of proinflammatory mediators, including a number
of vasoactive cytokines resulting in acute allergic, or immediate (type I) hypersensitivity
reactions [Gordon et al, Nature 346: 274-276 (1990) & Galli, N. Engl. J. Med., 328:257-
-28-
265 (1993)]. A crucial role for JAK3 in IgE receptor-mediated mast cell responses in
vitro and in vivo has been established [Malaviya, et al, Biochem. Biophys. Res. Commun.
257: 807-813 (1999)]. In addition, the prevention of type I hypersensitivity reactions,
including anaphylaxis, mediated by mast cell-activation through inhibition of JAK3 has
also ocen reported [Malaviya et al, J. Biol. Chem. 274:27028-27038 (1999)]. Targeting
mast cells with JAK3 inhibitors modulated mast cell degranulation in vitro and prevented
IgE receptor/antigen-mediated anaphylactic reactions in vivo.
[0089] A recent study described the successful targeting of JAK3 for immune
suppression and allograft acceptance. The study demonstrated a dose-dependent survival
of Buffalo heart allograft in Wistar Furth recipients upon administration of inhibitors of
JAK3 indicating the possibility of regulating unwanted immune responses in graft versus
host disease [Kirken, transpl. proc. 33:3268-3270 (2001)].
[0090] IL-4-mediated STAT-phosphorylation has been implicated as the mechanism
involved in early and late stages of rheumatoid arthritis (RA). Up-regulation of
proinflammatory cytokines in RA synovium and synovial fluid is a characteristic of the
disease. It has been demostrated that IL-4-mediated activation of IL-4/STAT pathway is
mediated through the Janus Kinases (JAK 1 & 3) and that IL-4-associated JAK kinases
are expressed in the RA synovium [Muller-Ladner, et al, J. Immunol. 164: 3894-3901
(2000)].
[0091] Familial amyotrophic lateral sclerosis (FALS) is a fatal neurodegenerative
disorder affecting about 10% of ALS patients. The survival rates of FALS mice were
increased upon treatment with a JAK3 specific inhibitor. This confirmed that JAK3 plays
a role in FALS [Trieu, et al, Biochem. Biophys. Res. Commun. 267: 22-25 (2000)].
[0092] Signal transducer and activator of transcription (STAT) proteins are activated
by, among others, the JAK family kinases. Results form a recent study suggested the
possibility of intervention in the JAK/STAT signaling pathway by targeting JAK family
kinases with specific inhibitors for the treatment of leukemia [Sudbeck, et al, Clin. Cancer
Res. 5:1569-1582 (1999)]. JAK3 specific compounds were shown to inhibit the
clonogenic growth of JAK3-expressing cell lines DAUDI, RAMOS, LCI; 19, NALM-6,
MOLT-3 and HL-60.
[0093] In animal models, TEL/JAK2 fusion proteins have induced myeloproliferative
disorders and in hematopoietic cell lines, introduction of TEL/JAK2 resulted in activation

of STAT1, STAT3, STAT5, and cytokine-independent growth [Schwaller, et al, EMBO J.
17: 5321-5333 (1998)].
[0094] Inhibition of JAK 3 and TYK 2 abrogated tyrosine phosphorylation of STAT3,
and inhibited cell growth of mycosis fungoides, a form of cutaneous T cell lymphoma.
These results implicated JAK family kinases in the constitutively activated JAK/STAT
pathway that is present in mycosis fungoides [Nielsen, et al, Proc. Nat. Acad. Sci. U.S.A.
94: 6764-6769 (1997)]. Similarly, STAT3, STAT5, JAK1 and JAK2 were demonstrated
to be constitutively activated in mouse T cell lymphoma characterized initially by LCK
over-expression, thus further implicating the JAK/STAT pathway in abnormal cell
growth [Yu, et al, J. Immunol. 159:5206-5210 (1997)]. In addition, IL-6 -mediated
STAT3 activation was blocked by an inhibitor of JAK, leading to sensitization of
myeloma cells to apoptosis [Catlett-Falcone, et al, Immunity 10:105-115 (1999)].
[0095] As a result of the biological importance of protein kinases, there is current
interest in therapeutically effective protein kinase inhibitors. Accordingly, there is still a
great need to develop inhibitors of protein kinases that are useful in treating various
diseases or conditions associated with protein kinase activation.
SUMMARY OF THE INVENTION
