As used herein, the term "trk" refers to the family of high affinity neurotrophin
receptors presently comprising trk A, trk B, and trk C, and other membrane associated
proteins to which a neurotrophin can bind.
As used herein, the term "VEGFR" refers to the family of high affinity vascular
endothelial growth factor receptors presently comprising VEGFR1, VEGFR2, VEGFR3,

As used herein, the terms "enhance" or "enhancing" when used to modify the
terms "function" or "survival" means that the presence of a compound of the present
invention has a positive effect on the function and/or survival of a trophic factor
responsive cell compared with a cell in the absence of the compound. For example, and
not by way of limitation, with respect to the survival of, e.g., a cholinergic neuron, a
compound of the present invention would evidence enhancement of survival of a
cholinergic neuronal population at risk of dying (due to, e.g., injury, a disease condition, a
degenerative condition or natural progression) when compared to a cholinergic neuronal
population not presented with such a compound, if the treated population has a

comparatively greater period of functionality than the non-treated population. As a further
example, and again not by way of limitation, with respect to the function of, e.g., a sensory
neuron, a compound of the present invention would evidence enhancement of the function
(e.g. neurite extension) of a sensory neuronal population when compared to a sensory
neuronal population not presented with such a compound, if the neurite extension of the
treated population is comparatively greater than the neurite extension of the non-treated
population.
As used herein, the terms "inhibit" or "inhibition" refer to a specified response of a
designated material (e.g., enzymatic activity) is comparatively decreased in the presence
of a compound of the present invention.
As used herein, the terms "cancer" or "cancerous" refer to any malignant
proliferation of cells in a mammal. Examples include prostate, benign prostate
hyperplasia, ovarian, breast, brain, lung, pancreatic, colorectal, gastric, stomach, solid
tumors, head and neck, neuroblastoma, renal cell carcinoma, lymphoma, leukemia, other
recognized malignancies of the hematopoietic systems, and other recognized cancers.
As used herein the terms "neuron", "cell of neuronal lineage" and "neuronal cell"
refer to a heterogeneous population of neuronal types having singular or multiple
transmitters and/or singular or multiple functions; preferably, these are cholinergic and
sensory neurons. As used herein, the phrase "cholinergic neuron" means neurons of the
Central Nervous System (CNS) and Peripheral Nervous System (PNS) whose
neurotransmitter is acetylcholine; exemplary are basal forebrain and spinal cord neurons.
As used herein, the phrase "sensory neuron" includes neurons responsive to environmental
cues (e.g., temperature, movement) from, e.g., skin, muscle and joints; exemplary is a
neuron from the DRG.
As used herein the term "trophic factor" refers to a molecule that directly or
indirectly affects the survival or function of a trophic factor responsive cell. Exemplary
trophic factors include Ciliary Neurotrophic Factor (CNTF), basic Fibroblast Growth
Factor (bFGF), insulin and insulin-like growth factors (e.g., IGF-I, IGF-H, IGF-III),
interferons, interleukins, cytokines, and the neurotrophins, including Nerve Growth Factor
(NGF), Neurotrophin-3 (NT-3), Neurotrophin-4/5 (NT-4/5) and Brain Derived
Neurotrophic Factor (BDNF).

As used herein the term "trophic factor-responsive cell" refers to a cell which
includes a receptor to which a trophic factor can specifically bind; examples include
neurons (e.g., cholinergic and sensory neurons) and non-neuronal cells (e.g., monocytes
and neoplastic cells).
As used herein the terms "trophic factor activity" and "trophic factor-induced
activity", refer to both endogenous and exogenous trophic factors, where "endogenous"
refers to a trophic factor normally present and "exogenous" refers to a trophic factor added
to a system. As defined, "trophic factor induced activity" includes activity induced by (1)
endogenous trophic factors; (2) exogenous trophic factors; and (3) a combination of
endogenous and exogenous trophic factors.
As used herein, the term "at risk of dying" in conjunction with a biological
material, e.g., a cell such as a neuron, refers to a state or condition which negatively
impacts the biological material such that the material has an increased likelihood of dying
due to such state or condition. For example, compounds disclosed herein can "rescue" or
enhance the survival of motoneurons which are naturally at risk of dying in an in ovo
model of programmed cell death. Similarly, for example, a neuron may be at risk of dying
due to the natural aging process which occasions the death of a neuron, or due to an injury,
such as a trauma to the head, which may be such that neurons and/or glia, for example,
impacted by such trauma may be at risk of dying. Further, for example, a neuron may be
at risk of dying due to a disease state or condition, as in the case of neurons at risk of
dying as occasioned by the disease ALS. Thus, by enhancing the survival of a cell at risk
of dying by use of a compound of the claimed invention is meant that such compound
decreases or prevents the risk of the death of the cell.
As used herein the term "contacting" refers to directly or indirectly causing
placement together of moieties, such that the moieties directly or indirectly come into
physical association with each other, whereby a desired outcome is achieved. Thus, as
used herein, one can "contact" a target cell with a compound as disclosed herein even
though the compound and cell do not necessarily physically join together (as, for example,
is the case where a ligand and a receptor physically join together), as long as the desired
outcome is achieved (e.g., enhancement of the survival of the cell). Contacting thus
includes acts such as placing moieties together in a container (e.g., adding a compound as

disclosed herein to a container comprising cells for in vitro studies) as well as
administration of the compound to a target entity (e.g., injecting a compound as disclosed
herein into a laboratory animal for in vivo testing, or into a human for therapy or treatment
purposes).
As used herein, a "therapeutically effective amount" refers to an amount of a
compound of the present invention effective to prevent or treat the symptoms of a
particular disorder.
As used herein, the term "subject" refers to a warm blooded animal such as a
mammal, preferably a human, or a human child, which is afflicted with, or has the
potential to be afflicted with one or more diseases and conditions described herein.
As used herein, the term "pharmaceutically acceptable" refers to those compounds,
materials, compositions, and/or dosage forms which are, within the scope of sound
medical judgment, suitable for contact with the tissues of human beings and animals
without excessive toxicity, irritation, allergic response, or other problem complications
commensurate with a reasonable benefit/risk ratio.
As used herein, "pharmaceutically acceptable salts" refer to derivatives of the
disclosed compounds wherein the parent compound is modified by making acid or base
salts thereof. Examples of pharmaceutically acceptable salts include, but are not limited
to, mineral or organic acid salts of basic residues such as amines; alkali or organic salts of
acidic residues such as carboxylic acids; and the like. The pharmaceutically acceptable
salts include the conventional non-toxic salts or the quaternary ammonium salts of the
parent compound formed, for example, from non-toxic inorganic or organic acids. For
example, such conventional non-toxic salts include those derived from inorganic acids
such as hydrochloric, hydrobromic, sulfuric, sulfamic, phosphoric, nitric and the like; and
the salts prepared from organic acids such as acetic, propionic, succinic, glycolic, stearic,
lactic, malic, tartaric, citric, ascorbic, pamoic, maleic, hydroxymaleic, phenylacetic,
glutamic, benzoic, salicylic, sulfanilic, 2-acetoxybenzoic, fumaric, toluenesulfonic,
methanesulfonic, ethane disulfonic, oxalic, isethionic, and the like.
The pharmaceutically acceptable salts of the present invention can be prepared
from the parent compound which contains a basic or acidic moiety by conventional
chemical methods. Generally, such salts can be prepared by reacting the free acid or base

forms of these compounds with a stoichiometric amount of the appropriate base or acid in
water or in an organic solvent, or in a mixture of the two. Generally, nonaqueous media
like ether, ethyl acetate, ethanol, isopropanol, or acetonitrile are preferred. Lists of
suitable salts are found in Remington's Pharmaceutical Sciences, 17th ed., Mack
Publishing Company, Easton, PA, 1985, p. 1418, the disclosure of which is hereby
incorporated by reference.
As used herein, the term "unit dose" refers to a single dose which is capable of
being administered to a patient, and which can be readily handled and packaged,
remaining as a physically and chemically stable unit dose comprising either the active
compound itself, or as a pharmaceutically acceptable composition, as described
hereinafter.
As used herein, "prodrug" is intended to include any covalently bonded carriers
which release the active parent compound as defined in the present invention in vivo when
such prodrug is administered to a mammalian subject. Since prodrugs are known to
enhance numerous desirable qualities of pharmaceuticals (e.g., solubility, bioavailability,
manufacturing, etc.) the compounds of the present invention may be delivered in prodrug
form. Thus, the present invention contemplates prodrugs of the claimed compounds,
compositions containing the same, and methods of delivering the same. Prodrugs of a
compound of the present invention may be prepared by modifying functional groups
present in the compound in such a way that the modifications are cleaved, either in routine
manipulation or in vivo, to the parent compound. Accordingly, prodrugs include, for
example, compounds of the present invention wherein a hydroxy, amino, or carboxy group
is bonded to any group that, when the prodrug is administered to a mammalian subject,
cleaves to form a free hydroxyl, free amino, or carboxylic acid, respectively. Examples
include, but are not limited to, acetate, formate and benzoate derivatives of alcohol and
amine functional groups; and alkyl, carbocyclic, aryl, and alkylaryl esters such as methyl,
ethyl, propyl, iso-propyl, butyl, isobutyl, sec-butyl, tert-butyl, cyclopropyl, phenyl, benzyl,
and phenethyl esters,.and the like.
It is recognized that compounds of the present invention may exist in various
stereoisomeric forms. As such, the compounds of the present invention include their
respective diastereomers or enantiomers. The compounds are normally prepared as

racemates and can conveniently be used as such, but individual diastereomers or
enantiomers can be isolated or synthesized by conventional techniques if so desired. Such
racemates and individual diastereomers or enantiomers and mixtures thereof form part of
the present invention.
It is well known in the art how to prepare and isolate such optically active forms.
Specific stereoisomers can be prepared by stereospecific synthesis using enantiomerically
pure or enantiomerically enriched starting materials. The specific stereoisomers of either
starting materials or products can be resolved and recovered by techniques known in the
art, such as resolution of racemic forms, normal, reverse-phase, and chiral
chromatography, recrystallization, enzymatic resolution, or fractional recrystallization of
addition salts formed by reagents used for that purpose. Useful methods of resolving and
recovering specific stereoisomers described in Eliel, E. L.; Wilen, S.H. Stereochemistry of
Organic Compounds; Wiley: New York, 1994, and Jacques, J, et al. Enantiomers,
Racemates, and Resolutions; Wiley: New York, 1981, each incorporated by reference
herein in their entireties.
It is further recognized that functional groups present on the compounds of the
present invention may contain protecting groups. For example, the amino acid side chain
substituents of the compounds of the present invention can be substituted with protecting
groups such as benzyloxycarbonyl or t-butoxycarbonyl groups. Protecting groups are
known per se as chemical functional groups that can be selectively appended to and
removed from functionalities, such as hydroxyl groups and carboxyl groups. These
groups are present in a chemical compound to render such functionality inert to chemical
reaction conditions to which the compound is exposed. Any of a variety of protecting
groups may be employed with the present invention. Preferred groups for protecting
lactams include silyl groups such as t-butyldimethylsilyl ("TBDMS"),
dimethoxybenzhydryl ("DMB"), acyl, benzyl, and methoxybenzyl groups. Preferred
groups for protecting hydroxy groups include TBS, acyl, benzyl ("Bn"),
benzyloxycarbonyl ("CBZ"), t-butyloxycarbonyl ("Boc"), and methoxymethyl. Many
other standard protecting groups employed by one skilled in the art can be found in
Greene, T.W. and Wuts, P.G.M., "Protective Groups in Organic Synthesis" 2d. Ed., Wiley
& Sons, 1991.

The general routes to prepare the examples shown in Tables 1-3 of the present
invention are shown in the Schemes 1-4. The intermediates used to prepare the examples
and their mass spectral data are shown in the Table B. The reagents and starting materials
are commercially available, or readily synthesized by well-known techniques by one of
ordinary skill in the arts. All processes disclosed in association with the present invention
are contemplated to be practiced on any scale, including milligram, gram, multigram,
kilogram, multikilogram or commercial industrial scale. All substituents in the synthetic
schemes, unless otherwise indicated, are as previously defined.



The general procedures to prepare the pyrrolocarbazoles of the present invention
are described in U.S. Pat. Nos. 5,705,511 ("the '511 patent") and 6,630,500, PCT Publ.
No. WO 00/47583, J. Heterocyclic Chemistry, 2001, 38, 591, and J..Heterocyclic
Chemistry, 2003,40, 135. In general, the lactam nitrogen or intermediate alcohol groups
of the intermediates outlined in Table B may be protected with such groups as acetyl,
substituted silyl, benzyl, Boc, or dimethoxybenzhydrol.
Intermediate 1-23 (wherein R is hydrogen) used to prepare examples in Table 2,
was prepared from the β-ketone, 2-methyl-l,4,6,7-tetrahydro-5H-indazol-5-one (Peet, N.
P.; LeTourneau, M. E.; Heterocycles, 1991, 32, 41) using methods described in the '511
patent and in /. Heterocyclic Chemistry, 2003, 40, 135.


As shown in Scheme 1, the N1-methyl pyrazole derivatives in Table 3 were
prepared from the 1-methyl α-ketone (7. Chem. Res., 1986,1401). The N2-methyl
pyrazole intermediates were prepared according to procedures in J. Heterocyclic Chem.
1992, 19, 1355.


Scheme 2 outlines the route to prepare carbamate-type derivatives, such as
Examples 1-2, and 70-72. An alternate method to preparing N, N-di-substituted
carbamates utilized a nitrophenyl carbonate intermediate which may be treated with
various primary or secondary amines. Similarly urea, O-carbamate, and N-carbamate
derivatives may be prepared from reaction of the appropriate amine or phenol intermediate
with an isocyanate or chloroformate or from the appropriate nitrophenyl carbonate,
nitrophenyl carbamate, or trichloromethylcarbonyl (see J. Org. Chem. 2003, 68,3733-
3735).

Scheme 3 outlines a route to prepare heteroaryl ethers from the corresponding
phenol using a base such as sodium hydride and a heteroaryl bromide or chloride.


Scheme 4 shows a route for the preparation of N-carbamates (examples 50-69) or
amides (examples 74-82) from the corresponding aniline intermediates 1-29. Amino
intermediates 1-29 were prepared by alkylation of the appropriate cyano-esters with the
appropriate alkyl iodide or bromide followed by nitration, and subsequent RaNi reduction
to provide the amino-lactam. The desired compounds were readily prepared from the
amine.
Heteroaryl ketones may be prepared using standard Friedel-Crafts type acylation
reactions.

To a well-stirred suspension of the CH2OH intermediates I, II, or III in 7 mL of methylene
chloride were added sequentially trifluoroacetic anhydride (5 equivalents) and N-methyl
morpholine (5 eq) at 5 °C and under argon atmosphere. The resulted suspension was
stirred at room temperature for 3 hours and the low boiling solvents were removed under
vacuum. A stirred solution of this tritrifluoroacetate intermediate in an appropriate alcohol
was heated to 80 °C for 6-48 hours in an oil bath. Gradually, the heterogeneous reaction
mixture became homogeneous. When no starting material was observed by HPLC the
reaction mixture was worked up by removing the solvent in vacuo. The residues was

Utility
The compounds of the present invention are useful, inter alia, as therapeutic agents.
Particularly, the compounds are useful for kinase inhibition, such as, for example, trk,
VEGFR, PDGFR, PKC, MLK, DLK, Tie-2, FLT-3, and CDK1-6. Various compounds of
the present invention show enhanced pharmaceutical properties over those disclosed in the
art and improved pharmacokinetic properties in mammals. The compounds of the present
invention show enhanced pharmaceutical properties over those disclosed in the art,
including increased MLK and DLK dual inhibition activity, or increased VEGFR and Tie-
2 dual inhibition activity, along with improved pharmacokinetic properties in mammals.
In one embodiment, the present invention provides a method for treating or
preventing diseases and disorders, such as those disclosed herein, which comprises
administering to a subject in need of such treatment or prevention a therapeutically
effective amount of a compound of the present invention.
In an additional embodiment, the present invention provides a method for
inhibiting trk kinase activity comprising providing a compound of the present invention in
an amount sufficient to result in effective inhibition. Particularly, inhibition of trk implies

utility in, for example, diseases of the prostate such as prostate cancer arid benign prostate
hyperplasia, as well as for the treatment of inflammation, such as neurological
inflammation and chronic arthritis inflammation. In a preferred embodiment, the trk
kinase receptor is trk A.
The majority of cancers have an absolute requirement for angiogenesis, the
process by which new blood vessels are formed. The most potent angiogenic cytokine is
vascular endothelial growth factor (VEGF) and there has been substantial research into the
development of VEGF/VEGF receptor (VEGFR) antagonists. Receptor tyrosine kinase
(RTK) inhibitors could have broad spectrum antitumor activity in patients with advanced
pre-treated breast and colorectal carcinoma and Kaposi's sarcoma. Potentially these agents
may play a role in the treatment of both early (adjuvant) and advanced cancer. The
importance of angiogenesis for the progressive growth and viability of solid tumors is well
established. Emerging data suggest an involvement of angiogenesis in the
pathophysiology of hematologic malignancies as well. Recently, authors have reported
increased angiogenesis in the bone marrow of patients with acute myeloid leukemia
(AML) and normalization of bone marrow microvessel density when patients achieved a
complete remission (CR) after induction chemotherapy. Tumor angiogenesis depends on
the expression of specific mediators that initiate a cascade of events leading to the
formation of new microvessels. Among these, VEGF (vascular endothelial growth factor),
FGF (fibroblast growth factor) play a pivotal role in the induction of neovascularization in
solid tumors. These cytokines stimulate migration and proliferation of endothelial cells
and induce angiogenesis in vivo. Recent data suggest an important role for these
mediators in hematologic malignancies as well. Isolated AML blasts overexpress VEGF
and VEGF receptor 2. Thus, the VEGF/VEGFR-2 pathway can promote the growth of
leukemic blasts in an autocrine and paracrine manner. Therefore, neovascularization and
angiogenic mediators/receptors may be promising targets for anti-angiogenic and anti-
leukemic treatment strategies. Thus, in other embodiments, the present invention provides
a method for treating or preventing angiogenic disorders where VEGFR kinase activity
contributes to pathological conditions, the method comprising providing a compound of
the present invention in an amount sufficient to result in the vascular endothelial growth
factor receptor being contacted with an effective inhibitory amount of the compound.

Inhibition of VEGFR implies utility in, for example, angiogenic disorders such as cancer
of solid tumors, endometriosis, macular degeneration, retinopathy, diabetic retinopathy,
psoriasis, hemangioblastoma, as well as other ocular diseases and cancers.
FLT3, a member of the receptor tyrosine kinase (RTK) class III, is preferentially
expressed on the surface of a high proportion of acute myeloid leukemia (AML) and B-
lineage acute lymphocytic leukemia (ALL) cells in addition to hematopoietic stem cells,
brain, placenta and liver. An interaction of FLT3 and its ligand has been shown to play an
important role in the survival, proliferation and differentiation of not only normal
hematopoetic cells but also leukemia cells. Mutations of the FLT3 gene was first reported
as an internal tandem duplication (ITD) of the juxtamembrane (JM) domain-coding
sequence, subsequently as a missense mutation of D835 within a kinase domain. ITD- and
D835-mutations are essentially found in AML and their frequencies are approximately 20
and 6% of adults with AML, respectively. Thus, mutation of the FLT3 gene is so far the
most frequent genetic alteration reported to be involved in AML. Several large-scale
studies in well-documented patients published to date have demonstrated that ITD-
mutation is strongly associated with leukocytosis and a poor prognosis. An inhibitor
compound of FLT3 tyrosine kinase have an application in treatment of leukemia. The
present invention provides a method for treating disorders characterized by responsiveness
to FLT3 inhibition, the method comprising providing a compound of the present invention
in an amount sufficient to result in the inhibition of FLT3.
Platelet-derived growth factor (PDGF) was one of the first polypeptide growth
factors identified that signals through a cell surface tyrosine kinase receptor (PDGF-R) to
stimulate various cellular functions including growth, proliferation, and differentiation.
Since then, several related genes have been identified constituting a family of ligands
(primarily PDGF A and B) and their cognate receptors (PDGF-R alpha and beta). To date,
PDGF expression has been shown in a number of different solid tumors, from
glioblastomas to prostate carcinomas. In these various tumor types, the biologic role of
PDGF signaling can vary from autocrine stimulation of cancer cell growth to more subtle
paracrine interactions involving adjacent stroma and even angiogenesis. Thus, in
additional embodiments, the present invention provides a method for treating or
preventing disorders where PDGFR activity contributes to pathological conditions, the

method comprising providing a compound of the present invention in an amount sufficient
to result in the platelet derived growth factor receptor being contacted with an effective
inhibitory amount of the compound. Inhibition of PDGFR implies utility in, for example,
various forms of neoplasia, rheumatoid arthritis, chronic arthritis, pulmonary fibrosis,
myelofibrosis, abnormal wound healing, diseases with cardiovascular end points, such as
atherosclerosis, restenosis, post-angioplasty restenosis, and the like.
In further embodiments, the present invention provides a method for treating or
preventing disorders where MLK activity contributes to pathological conditions, such as
those listed above, wherein the method comprises providing a compound of the present
invention in an amount sufficient to result in the MLK receptor being contacted with an
effective inhibitory amount of the compound. Inhibition of MLK implies utility in, for
example, forms of cancer where MLKs play a pathological role as well as in neurological
disorders.
In still other embodiments, the present invention provides a method for treating
disorders characterized by the aberrant activity of trophic factor responsive cells, the
method comprising providing a compound of the present invention in an amount sufficient
to result in the trophic factor cell receptor being contacted with an effective activity
inducing amount of the compound. In certain preferred embodiments, the activity of the
trophic factor responsive cells is ChAT activity.
Fibroblast growth factor receptors (FGFR) are members of a family of
polypeptides synthesized by a variety of cell types during the processes of embryonic
development and in adult tissues. FGFR have been detected in normal and malignant cells
and are involved in biological events that include mitogenic and angiogenic activity with a
consequent crucial role in cell differentiation and development. To activate signal
transduction pathways, FGFR are coupled to fibroblast growth factors (FGF) and heparan
sulfate (HS) proteoglycans to form a biologically fundamental ternary complex. Based on
these considerations, inhibitors able to block the signaling cascade through a direct
interaction with FGFR could have antiangiogenesis and subsequent antitumor activity.
Accordingly, the present invention provides a method for treating disorders characterized
by the aberrant activity of FGF responsive cells, the method comprising providing a

compound of the present invention in an amount sufficient to result in the FGFR being
contacted with an effective activity inducing amount of the compound.
The compounds of the present invention can also have positive effects on the
function and survival of trophic factor responsive cells by promoting the survival of
neurons. With respect to the survival of a cholinergic neuron, for example, the compound
may preserve the survival of a cholinergic neuronal population at risk of dying (due to,
e.g., injury, a disease condition, a degenerative condition or natural progression) when
compared to a cholinergic neuronal population not presented with such compound, if the
treated population has a comparatively greater period of functionality than the non-treated
population.
A variety of neurological disorders are characterized by neuronal cells which are
dying, injured, functionally compromised, undergoing axonal degeneration, at risk of
dying, etc. These neurodegenerative diseases and disorders include, but are not limited to,
Alzheimer's disease; motor neuron disorders (e.g. amyotrophic lateral sclerosis);
Parkinson's disease; cerebrovascular disorders (e.g., stroke, ischemia); Huntington's
disease; AIDS dementia; epilepsy; multiple sclerosis; peripheral neuropathies including
diabetic neuropathy and chemotherapy induced peripheral neuropathy, AID related
peripheral neuropathy; disorders induced by excitatory amino acids; and disorders
associated with concussive or penetrating injuries of the brain or spinal cord.
In other preferred embodiments, the compounds of the present invention are useful
for treating or preventing multiple myeloma and leukemias including, but not limited to,
acute myelogenous leukemia, chronic myelogenous leukemia, acute lymphocytic
leukemia, and chronic lymphocytic leukemia.
In additional embodiments, the present compounds are also useful in the treatment
of disorders associated with decreased ChAT activity or the death, injury to spinal cord
motoneurons, and also have utility in, for example, diseases associated with apoptotic cell
death of the central and peripheral nervous system, immune system and in inflammatory
diseases. ChAT catalyzes the synthesis of the neurotransmitter acetylcholine, and it is
considered an enzymatic marker for a functional cholinergic neuron. A functional neuron
is also capable of survival. Neuron survival is assayed by quantification of the specific
uptake and enzymatic conversion of a dye (e.g., calcein AM) by living neurons. The

compounds described herein may also find utility in the treatment of disease states
involving malignant cell proliferation, such as many cancers.
Additional embodiments of the invention are directed to the use of any compound
described herein, and stereoisomers or pharmaceutically acceptable salts thereof, in the
treatment and/or prevention of any of the conditions, diseases and disorders described
above. Further embodiments are directed to the use of the compounds described herein,
and stereoisomers or pharmaceutically acceptable salts thereof, in the manufacture of a
medicament for treating and/or preventing said conditions, disorders and diseases.
The compounds of the present invention have important functional
pharmacological activities which find utility in a variety of settings, including both
research and therapeutic arenas. For ease of presentation, and in order not to limit the
range of utilities for which these compounds can be characterized, the activities of the
compounds of the present invention can be generally described as follows:
A. Inhibition of enzymatic activity
B. Effect on the function and/or survival of trophic factor responsive cells
C. Inhibition of inflammation-associated responses
D. Inhibition of cell growth associated with hyperproliferative states
E. Inhibition of developmentally programmed motoneuron death
Inhibition of enzymatic activity can be determined using, for example, VEGFR
inhibition (e.g., VEGFR2 inhibition), MLK inhibition (e.g., MLK1, MLK2 or MLK3
inhibition), PDGFR kinase inhibition, NGF-stimulated trk phosphorylation, PKC
inhibition, or trk tyrosine kinase inhibition assays. Effect on the function and/or survival of
trophic factor responsive cells, e.g., cells of a neuronal lineage, can be established using
any of the following assays: (1) cultured spinal cord choline acetyltransferase ("ChAT")
assay; (2) cultured dorsal root ganglion ("DRG") neurite extension assay; (3) cultured

basal forebrain neuron ("BFN") ChAT activity assay. Inhibition of inflammation-
associated response can be established using an indoleamine 2,3-dioxygenase ("EDO")
mRNA assay. Inhibition of cell growth associated with hyperproliferative states can be
determined by measuring the growth of cell lines of interest, such as an AT2 line in the
case of prostate cancer. Inhibition of developmentally programmed motoneuron death can
be assessed in ovo using embryonic chick somatic motoneurons, which cells undergo
naturally occurring death between embryonic days 6 and 10, and analyzing inhibition of
such naturally occurring cell death as mediated by the compounds disclosed herein.
The inhibition of enzymatic activity by the compounds of the present invention can
be determined using, for example, the following assays:
VEGFR Inhibition Assay
MLK Inhibition Assay
PKC Activity Inhibition Assay
trkA Tyrosine Kinase Activity Inhibition Assay
Tie-2 Inhibition Assay

Platelet Derived Growth Factor Receptor (PDGFR) inhibition assay
A description of assays that may be used in connection with the present invention
are set forth below. They are not intended, nor are they to be construed, as limiting the
scope of the disclosure.
Inhibition of trkA Tyrosine Kinase Activity
Selected compounds of the present invention were tested for their ability to inhibit
the kinase activity of baculovirus-expressed human trkA cytoplasmic domain using an
ELISA-based assay as previously described (Angeles et al., Anal. Biochem. 236: 49-55,
1996). Briefly, the 96-well microtiter plate was coated with substrate solution
(recombinant human phospholipase C- γl/glutathione S-transferase fusion protein (Rotin
et al., EMBO J., 11: 559-567, 1992). Inhibition studies were performed in 100 µl assay
mixtures containing 50 mM Hepes, pH 7.4,40µM ATP, 10 mM MnCl2, 0.1% BSA, 2%
DMSO, and various concentrations of inhibitor. The reaction was initiated by addition of

trkA kinase and allowed to proceed for 15 minutes at 37°C. An antibody to
phosphotyrosine (UBI) was then added, followed by a secondary enzyme-conjugated
antibody, alkaline phosphatase-labelled goat anti-mouse IgG (Bio-Rad). The activity of
the bound enzyme was measured via an amplified detection system (Gibco-BRL).
Inhibition data were analyzed using the sigmoidal dose-response (variable slope) equation
in GraphPad Prism. The concentration that resulted in 50% inhibition of kinase activity is
referred to as "IC50".

Inhibition of Vascular Endothelial Growth Factor Receptor Kinase Activity
Selected compounds of the present invention were examined for their inhibitory
effects on the kinase activity of baculovirus-expressed VEGF receptor (human flk-1,
KDR, VEGFR2) kinase domain using the procedure described for the trkA kinase ELISA
assay described above. The kinase reaction mixture, consisting of 50 mM Hepes, pH 7.4,
40 µM ATP, 10 mM MnCl2, 0.1% BSA, 2% DMSO, and various concentrations of
inhibitor, was transferred to PLC-γ/GST-coated plates. VEGFR kinase was added and the
reaction was allowed to proceed for 15 min. at 37 °C. Detection of phosphorylated
product was accomplished by addition of anti-phosphotyrosine antibody (UBI). A
secondary enzyme-conjugated antibody was delivered to capture the antibody-
phosphorylated PLC- γ/GST complex. The activity of the bound enzyme was measured via
an amplified detection system (Gibco-BRL). Inhibition data were analyzed using the
sigmoidal dose-response (variable slope) equation in GraphPad Prism.
Inhibition of Mixed Lineage Kinase-1 Activity
The kinase activity of MLK1 was assessed using the Millipore Multiscreen TCA
"in-plate" format as described for protein kinase C (Pitt & Lee, J. Biomol. Screening, 1:
47-51,1996). Briefly, each 50-µl assay mixture contained 20 mM Hepes, pH 7.0,1 mM
EGTA, 10 mM MgCl2,1 mM DTT, 25 mM β-glycerophosphate, 60 uM ATP, 0.25 µCi [γ-
32P]ATP, 0.1% BSA, 500 µg/ml myelin basic protein (UBI #13-104), 2% DMSO, 1 uM of
test compound, and 1 µg/ml of baculoviral GST-MLK1KD. Samples were incubated for 15
min at 37°C. The reaction was stopped by adding ice cold 50% TCA and the proteins
were allowed to precipitate for 30 min at 4°C. The plates were then washed with ice cold
25% TCA. Supermix scintillation cocktail was added, and the plates were allowed to
equilibrate for 1-2 hours prior to counting using the Wallace MicroBeta 1450 PLUS
scintillation counter.
Dual Leucine Zipper Bearing Kinase Assay
Compounds were tested for their ability to inhibit the kinase activity of
recombinant baculoviral human DLK, containing the kinase domain and leucine zipper.

Activity was measured in 384-well FluoroNunc plates (Cat#460372) using a time-resolved
fluorescence readout (PerkinElmer Application Note 1234-968). Plates were coated with
30 µl of the protein substrate MKK7 (Merritt et al. 1999) at a concentration of 20 µg/ml in
Tris buffered saline (TBS). Each 30 jxl assay contained 20 mM MOPS (pH 7.2), 15 mM
MgCl2,0.1 mM Na3VO4,1 mM DTT, 5 mM EGTA, 25 mM β-glycerophosphate, 0.1%
BSA, 100 uM ATP, and 2.5% DMSO. Reactions were started by the addition of 10 ng/ml
GST-hDLKKD/LZ. For IC50 determinations, a 10-point dose response curve was generated
for each compound. Plates were incubated at 37°C for 30 minutes, and the reactions
stopped by the addition of 100 mM EDTA. Product was detected using Europium-labeled
anti-phosphothreonine (Wallac#AD0093; diluted 1:10000 in 3%BSA/T-TBS). Following
overnight capture at 4°C, 50 µl enhancement solution (Wallac #1244-105) was added and
the plate gently agitated for 5 min. The fluorescence of the resulting solution was then
measured using the time-resolved fluorescence (TRF) mode in the MultilabelReader
(Victor2 Model # 1420-018 or Envision Model # 2100). Inhibition data was analyzed
using GraphPad PRISM. See also Merritt, S.E., Mata, M., Nihalani, D., Zhu, C, Hu, X.,
and Holzman, L.B. (1999) The Mixed Lineage Kinase DLK utilizes MKK7 and not
MKK4 as Substrate. J. Biol. Chem. 274,10195-10202.
Tie-2 Tyrosine Kinase Assay
Compounds were tested for their ability to inhibit the kinase activity of
recombinant baculoviral human His6-Tie2 cytoplasmic domain using a modification of the
ELISA described for trkA (Angeles et al, 1996). A 384-well plate format was used for
single-point screening while IC50S were performed on 96-well plates. For single-point
screening, each barcoded 384-well Costar High Binding plate (Cat # 3703) was coated
with 50 µl/well of 10 µg/ml substrate solution (recombinant human GST- PLC-γ; Rotin et
al., 1992) in Tris-buffered saline (TBS). The Tie2 activity was measured in 50-µl assay
mixtures containing 50 mM HEPES (pH 7.2), 40 µM ATP, 10 mM MnCl2, 2.5% DMSO,
0.05% BSA, and 200 ng/ml His6-Tie2CD. For IC50 determinations, the assays were run as
described above but in 96-well Costar High Binding plates (Cat # 3703) and with the
volumes doubled. A 10-point dose response curve was generated for each compound. The
kinase reaction was allowed to proceed at 37°C for 20 minutes. The detection antibody,

N1-Eu anti-phosphotyrosine (PT66) antibody (Wallac #AD0041), was added at 1:2000
diluted in block buffer [3% BSA in TBS with 0.05% Tween-20 (TBST)]. After one-hour
incubation at 37°C, 50 µl of enhancement solution (Wallac #1244-105) was added and the
plate was gently agitated. The fluorescence of the resulting solution was then measured
using the time-resolved fluorescence (TRF) mode in the Multilabel Reader (Victor2 Model
# 1420-018 or Envision Model # 2100). Inhibition data were analyzed using ActivityBase
and IC50 curves were generated using XLFit. The cited references are as follows:
