FIELD OF THE INVENTION
[0002] The present invention relates to novel substituted
2-amino-fused heterocyclic compounds, such as 2-amino-quinolines,
2-amino-isoquinolines, and 2-amino-quinazolines, compounds of
formula (I), to pharmaceutical compositions comprising the
compounds, as well as to the use of the compounds in the
preparation of a medicament for use in the treatment or prevention
of a disease or medical condition mediated through c-Jun N-terminal
kinases (JNKs), leading to a decreased glucose threshold for
insulin secretion. In addition the compounds are predicted to lower
blood glucose by increasing hepatic glucose uptake. Such compounds
may have utility in the treatment of Type 2 diabetes and
obesity.
BACKGROUND OF THE INVENTION
[0003] 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
c-Jun N-terminal kinases (JNKs), also known as stress activated
protein kinase (SAPK). 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., EMBO J., 15:2760-70
(1996)]. While JNK1 and JNK2 express in many tissues, JNK3
specifically expresses in the brain. Thus, JNK3 has a potential to
be particularly involved in nervous function. The JNK signal
transduction system of stress response MAP kinase family system is
activated by changes in osmotic pressure, DNA damage, anisomycine,
heat shock, ultraviolet radiation, ischemia, inflammatory cytokines
and the like and various stress stimulations relating to apoptosis
induction, it is considered to constitute a major intracellular
information transduction path responsible for stress response
(Biochemica et Biophysica Acta, vol. 1333, pp. F85-F104 (1997)).
From an experiment using a JNK1 deletion mouse, JNK is reported to
be an important mediator involved in obesity and insulin resistance
(Nature, vol. 420, pp. 333-336 (2002)).

expression of gene(s) maintained under hormone expression control,
or to repress expression of gene(s) maintained under such
control.
[0075] The term "obesity" or "obese", as used herein, refers
generally to individuals who are at least about 20-30% over the
average weight for his/her age, sex and height. Technically,
"obese" is defined, for males, as individuals whose body mass index
is greater than 27.8 kg/m.sup.2, and for females, as individuals
whose body mass index is greater than 27.3 kg/m.sup.2. Those of
skill in the art readily recognize that the invention method is not
limited to those who fall within the above criteria. Indeed, the
method of the invention can also be advantageously practiced by
individuals who fall outside of these traditional criteria, for
example, by those who may be prone to obesity.
[0076] The term "inflammatory disorders", as used herein, refers to
disorders such as rheumatoid arthritis, ankylosing spondylitis,
psoriatic arthritis, psoriasis, chondrocalcinosis, gout,
inflammatory bowel disease, ulcerative colitis, Crohn's disease,

animal, or human that is being sought by a researcher,
veterinarian, medical doctor or other.
[0078] The phrase "amount . . . effective to lower blood glucose
levels", as used herein, refers to levels of compound sufficient to
provide circulating concentrations high enough to accomplish the
desired effect. Such a concentration typically falls in the range
of about 10 nM up to 2 .mu.M; with concentrations in the range of
about 100 nM up to 500 nM being preferred. As noted previously,
since the activity of different compounds which fall within the
definition of Formula (I) as set forth above may vary considerably,
and since individual subjects may present a wide variation in
severity of symptoms, it is up to the practitioner to determine a
subject's response to treatment and vary the dosages
accordingly.
[0079] The phrase "insulin resistance", as used herein, refers to
the reduced sensitivity to the actions of insulin in the whole body
or individual tissues, such as skeletal muscle tissue, myocardial
tissue, fat tissue or liver tissue. Insulin resistance occurs in
many individuals with or without diabetes mellitus.
[0080] The phrase "insulin resistance syndrome", as used herein,
refers to the cluster of manifestations that include insulin
resistance, hyperinsulinemia, non insulin dependent diabetes
mellitus (NIDDM), arterial hypertension, central (visceral)
obesity, and dyslipidemia.
[0081] Certain compounds of formula (I) may have asymmetric centers
and therefore exist in different enantiomeric forms. All optical
isomers and stereoisomers of the compounds of formula (I), and
mixtures thereof, are considered to be within the scope of the
invention. With respect to the compounds of formula (I), the
invention includes the use of a racemate, one or more enantiomeric
forms, one or more diastereomeric forms, or mixtures thereof. The
compounds of formula (I) may also exist as tautomers. This
invention relates to the use of all such tautomers and mixtures
thereof.
[0082] Certain functional groups contained within the compounds of
the present invention can be substituted for bioisosteric groups,
that is, groups which have similar spatial or electronic
requirements to the parent group, but exhibit differing or improved
physicochemical or other properties. Suitable examples are well
known to those of skill in the art, and include, but are not
limited to moieties described in Patini et al., Chem. Rev, 1996,
96, 3147-3176 and references cited therein.
[0083] The subject invention also includes isotopically-labelled
compounds, which are identical to those recited in formula (I), but
for the fact that one or more atoms are replaced by an atom having
an atomic mass or mass number different from the atomic mass or
mass number usually found in nature. Examples of isotopes that can
be incorporated into compounds of the invention include isotopes of
hydrogen, carbon, nitrogen, oxygen, phosphorous, fluorine and
chlorine, such as .sup.2H, .sup.3H, .sup.13C, .sup.14C, .sup.15N,
.sup.18O, .sup.17O, .sup.31P, .sup.32P, .sup.35S, .sup.18F, and
.sup.36Cl, respectively. Compounds of the present invention and
pharmaceutically acceptable salts or solvates of said compounds
which contain the aforementioned isotopes and/or other isotopes of
other atoms are within the scope of this invention. Certain
isotopically-labelled compounds of the present invention, for
example those into which radioactive isotopes such as .sup.3H and
.sup.14C are incorporated, are useful in drug and/or substrate
tissue distribution assays. Tritiated, i.e., .sup.3H, and
carbon-14, i.e., .sup.14C, isotopes are particularly preferred for
their ease of preparation and detectability. Further, substitution
with heavier isotopes such as deuterium, i.e., .sup.2H, can afford
certain therapeutic advantages resulting from greater metabolic
stability, for example increased in vivo half-life or reduced
dosage requirements and, hence, may be preferred in some
circumstances. Isotopically labeled compounds of formula (I) of
this invention thereof can generally be prepared by carrying out
the procedures disclosed in the Schemes and/or in the Examples
below, by substituting a readily available isotopically labelled
reagent for a non-isotopically labelled reagent.
[0084] Other aspects, advantages, and features of the invention
will become apparent from the detailed description below.

of NaH in THF at room temperature presumably formed the
amino-sodium salt. This reaction accompanied a visible evolvement
of H.sub.2. Let the reaction go for 10 minutes before distributing
the solution to four vials containing aldehydes and ketones,
respectively. To these four vials 4.0 eq of Ti(OiPr).sub.4 liquid
was added. The vials were capped and placed in a 50.degree. C.
heating block in fumehood, and stirred for 14 h. After cooling to

to the above reaction vials, respectively, and stirred for 14 h.
2-methoxylethyl ether appeared to solubilize NaBH.sub.4 better and
can also be used for the reduction. Carefully, 2N HCl aqueous
solution was added to allow the pH to reach 1 or 2. The mixture was
stirred for 1 h, and then the pH was adjusted to 8 by adding 2N
aqueous NaOH. Precipitate was removed by passing the mixture

which showed the yields of the desired products ranging from 40 to
70%.
[0105] Any of the above compounds described in schemes A-S can be
converted into another analogous compound by standard chemical

[0106] The compounds of the present invention may have asymmetric
carbon atoms. Diasteromeric mixtures can be separated into their
individual diastereomers on the basis of their physical chemical
differences by methods known to those skilled in the art, for
example, by chromatography or fractional crystallization.
Enantiomers can be separated by converting the enantiomeric
mixtures into a diastereomric mixture by reaction with an
appropriate optically active compound (e.g., alcohol), separating
the diastereomers and converting (e.g., hydrolyzing) the individual
diastereomers to the corresponding pure enantiomers. All such
isomers, including diastereomeric mixtures and pure enantiomers are
considered as part of the invention.
[0107] The compounds of formulas (I) that are basic in nature are
capable of forming a wide variety of different salts with various
inorganic and organic acids. Although such salts must be
pharmaceutically acceptable for administration to animals, it is
often desirable in practice to initially isolate the compound of
formula (I) from the reaction mixture as a pharmaceutically
unacceptable salt and then simply convert the latter back to the
free base compound by treatment with an alkaline reagent and
subsequently convert the latter free base to a pharmaceutically
acceptable acid addition salt. The acid addition salts of the base
compounds of this invention are readily prepared by treating the
base compound with a substantially equivalent amount of the chosen
mineral or organic acid in an aqueous solvent medium or in a
suitable organic solvent, such as methanol or ethanol. Upon careful
evaporation of the solvent, the desired solid salt is readily
obtained. The desired acid salt can also be precipitated from a
solution of the free base in an organic solvent by adding to the
solution an appropriate mineral or organic acid.
[0108] Those compounds of formula (I) that are acidic in nature are
capable of forming base salts with various pharmacologically
acceptable cations. Examples of such salts include the alkali metal
or alkaline-earth metal salts and particularly, the sodium and
potassium salts. These salts are all prepared by conventional
techniques. The chemical bases which are used as reagents to
prepare the pharmaceutically acceptable base salts of this
invention are those which form non-toxic base salts with the acidic
compounds of formula (I). Such non-toxic base salts include those
derived from such pharmacologically acceptable cations as sodium,
potassium calcium and magnesium, etc. These salts can easily be
prepared by treating the corresponding acidic compounds with an
aqueous solution containing the desired pharmacologically
acceptable cations, and then evaporating the resulting solution to
dryness, preferably under reduced pressure. Alternatively, they may
also be prepared by mixing lower alkanolic solutions of the acidic
compounds and the desired alkali metal alkoxide together, and then
evaporating the resulting solution to dryness in the same manner as
before. In either case, stoichiometric quantities of reagents are
preferably employed in order to ensure completeness of reaction and
maximum yields of the desired final product.
[0109] The compounds of the present invention may also be useful in
the treatment of other metabolic disorders associated with impaired
glucose utilization and insulin resistance include major late-stage
complications of NIDDM, such as diabetic angiopathy,
atherosclerosis, diabetic nephropathy, diabetic neuropathy, and
diabetic ocular complications such as retinopathy, cataract
formation and glaucoma, and many other conditions linked to NIDDM,
including dyslipidemia glucocorticoid induced insulin resistance,
dyslipidemia, polycysitic ovarian syndrome, obesity, hyperglycemia,
hyperlipidemia, hypercholesteremia, hypertriglyceridemia,
hyperinsulinemia, and hypertension. Brief definitions of these
conditions are available in any medical dictionary, for instance,

Goodman and Gilman's The Pharmaceutical Basis of Therapeutics,
current edition, Pergamon Press; and Remington's Pharmaceutical
Sciences, current edition. Mack Publishing, Co., Easton, Pa. These
techniques can be employed in appropriate aspects and embodiments

flavoring, sweetening, coloring and preserving in order to produce
pharmaceutically elegant and palatable preparations. Tablets may
contain pharmaceutically acceptable excipients as an aid in the
manufacture of such tablets. As is conventional in the art these
tablets may be coated with a pharmaceutically acceptable enteric
coating, such as glyceryl monostearate or glyceryl distearate, to
delay disintegration and absorption in the gastrointestinal tract
to provide a sustained action over a longer period.
[0113] Formulations for oral use may be in the form of hard gelatin
capsules wherein the active ingredient is mixed with an inert solid
diluent, for example, calcium carbonate, calcium phosphate or
kaolin. They may also be in the form of soft gelatin capsules
wherein the active ingredient is mixed with water or an oil medium,
such as peanut oil, liquid paraffin or olive oil.

hydroxypropylmethyl cellulose, sodium alginate,
polyvinylpyrrolidone, gum tragacanth and gum acacia; a dispersing
or wetting agent that may be a naturally occurring phosphatide such
as lecithin, a condensation product of ethylene oxide and a long
chain fatty acid, for example polyoxyethylene stearate, a
condensation product of ethylene oxide and a long chain aliphatic
alcohol such as heptadecaethylenoxycetanol, a condensation product
of ethylene oxide and a partial ester derived from a fatty acid and
hexitol such as polyoxyethylene sorbitol monooleate or a fatty acid
hexitol anhydrides such as polyoxyethylene sorbitan monooleate.
[0115] The pharmaceutical compositions may be in the form of a
sterile injectable aqueous or oleagenous suspension. This
suspension may be formulated according to know methods using those
suitable dispersing or wetting agents and suspending agents that
have been mentioned above. The sterile injectable preparation may
also be formulated as a suspension in a non toxic
perenterally-acceptable diluent or solvent, for example as a
solution in 1,3-butanediol. Among the acceptable vehicles and
solvents that may be employed are water, Ringers solution and
isotonic sodium chloride solution. For this purpose any bland fixed
oil may be employed including synthetic mono- or diglycerides. In
addition fatty acids such as oleic acid find use in the preparation
of injectables.
[0116] The amino heterocyclyl compounds of formula (I) may also be
administered in the form of suppositories for rectal administration
of the drug. These compositions can be prepared by mixing the drug
with a suitable non-irritating excipient that is solid at about 25
Celcius but liquid at rectal temperature and will therefore melt in
the rectum to release the drug. Such materials include cocoa butter
and other glycerides.
[0117] For topical use preparations, for example, creams,
ointments, jellies solutions, or suspensions, containing the
compounds of the present invention are employed.
[0118] The amino heterocyclyl compounds of formula (I) may also be
administered in the form of liposome delivery systems such as small
unilamellar vesicles, large unilamellar vesicles and multimellar
vesicles. Liposomes can be formed from a variety of phospholipides,
such as cholesterol, stearylamine or phosphatidylcholines.
[0119] Dosage levels of the compounds of the present invention are
of the order of about 0.5 mg/kg body weight to about 100 mg/kg body
weight. A preferred dosage rate is between about 30 mg/kg body
weight to about 100 mg/kg body weight. It will be understood,
however, that the specific dose level for any particular patient
will depend upon a number of factors including the activity of the
particular compound being administered, the age, body weight,
general health, sex, diet, time of administration, route of
administration, rate of excretion, drug combination and the
severity of the particular disease undergoing therapy. To enhance
the therapeutic activity of the present compounds they may be
administered concomitantly with other orally active antidiabetic
compounds such as the sulfonylureas, for example, tolbutamide and
the like.

illustrate and exemplify the compounds of the present invention and
methods of preparing such compounds. It is to be understood that
the scope of the present invention is not limited in any way by the
scope of the following examples and preparations. In the following

chromatography (TLC) was performed using glass-backed silica gel 60
F 254 precoated plates (Merck Art 5719) and eluted with appropriate
solvent ratios (v/v). Reactions were assayed by TLC or LCMS and
terminated as judged by the consumption of starting material.
Visualization of the TLC plates was done with UV light (254 nM
wavelength) or with an appropriate TLC visualizing solvent and
activated with heat. Flash column chromatography (Still et al., J.
Org. Chem., 1978, 43, 2923) was performed using silica gel 60
(Merck Art 9385) or various MPLC systems, such as Biotage or ISCO
purification system.
[0124] The compound structures in the examples below were confirmed
by one or more of the following methods: proton magnetic resonance
spectroscopy, mass spectroscopy, and elemental microanalysis.
Proton magnetic resonance (.sup.1H NMR) spectra were determined
using a Bruker spectrometer operating at a field strength of 300 or
400 megahertz (MHz). Chemical shifts are reported in parts per
million (PPM, 6) downfield from an internal tetramethylsilane
standard. Alternatively, .sup.1H NMR spectra were referenced to
signals from residual protons in deuterated solvents as follows:
CDCl.sub.3=7.25 ppm; DMSO-d.sub.6=2.49 ppm; C.sub.6D.sub.6=7.16
ppm; CD.sub.3OD=3.30 ppm. Peak multiplicities are designated as
follows: s, singlet; d, doublet; dd, doublet of doublets; t,
triplet; dt, doublet of triplets; q, quartet; br, broadened; m,
multiplet. Coupling constants are given in Hertz (Hz). Mass spectra
(MS) data were obtained using Agilent mass spectrometer with APCI
or ESI ionization. Elemental microanalyses were performed by
Atlantic Microlab Inc. and gave results for the elements stated
within .+-.0.4% of the theoretical values.

Example 1
2-(4-methoxyphenyl)-N-[6-(1H-pyrazol-4-yl)isoquinolin-3-yl]acetamide
##STR00048##
[0129] Activation of (4-Methoxy-phenyl)-acetic acid (315.6 mg, 1.9
mmol) is accomplished by treatment of the carboxylic acid in DMA (5
mL) with HATU (802.6 mg, 2.1 mmol) and triethylamine (388.2 mg, 3.8
mmol) at room temperature for 1 hour. The
6-(1H-Pyrazol-4-yl)-isoquinolin-3-ylamine (200.0 mg, 0.9 mmol) was
added and the mixture was stirred at 75.degree. C. for 24 hours.
The reaction was monitered by LC/MS. Evaporation of DMA gave a
residue that was washed with NaHCO.sub.3 to remove the by-products
from HATU. The crude residue then was dissolved in MeOH (10 mL) and
was treated with K.sub.2CO.sub.3 (26.0 mg, 0.5 mmol) at 75.degree.
C. for 18 hrs. The solvent was evaporated and the product extracted
with CH.sub.2Cl.sub.2 (20 mL). The extracts were washed with water
(3.times.10 mL) and evaporated. The crude product was purified by
ISCO (with petroleum ether:ethyl acetate 50:50) to give the title
compound as a light yellow crystalline solid product (143.3 mg,
41.4%). .sup.1H NMR (DMSO-d.sub.6, 400 MHz): .delta. 3.68 (2H, s),

Preparation of Intermediate 1:
N-(4-Bromobenzyl)-2,2-diethoxyethanimidamide
##STR00049##
[0131] In a 2 L, three-neck round bottom flask (equipped with
magnetic stir bar, thermometer, and addition funnel), charged
diethoxyacetonitrile (111.1 g, 860 mmol) and methanol (620 mL,
anhydrous) while under a steady nitrogen flow. Via an addition
funnel, slowly charged 25 wt % solution of sodium methoxide (4.64
g, 86 mmol, 19.7 mL) in methanol. (Note: addition is slightly
exothermic). The mixture was stirred for 15 h, at which point, the
solvent was removed under vacuum (Note: starting material had not
been completely converted according to NMR). The residue was
dissolved in methanol and charged with a fresh sodium methoxide
solution--same concentration/equivalents--and stirred another 15
h). The solvent was removed under vacuum and the residue was
dissolved in diethyl ether (1.0 L), with the organic phase washed
with water (3.times.500 mL), then brine (1.times.300 mL). The
organic layer was dried over magnesium sulfate, the salts filtered
and the solvent reduced under vacuum to give 89.9 g of a crude
mixture of methyl 2,2-diethoxyethanimidoate and un-reacted starting
material (10-12 mol % by NMR) as a thin oil. Note that best yields
of the imidate are obtained when the organic layer is stripped of
at 400 mbar and 45.degree. C. because of its volatility.
[0132] The oil was dissolved in methanol (300 mL,) and placed into
a 2 L round bottom flask (equipped with magnetic stir bar, reflux
condenser) along with 1-(4-bromophenyl)methanamine (100.0 g, 537
mmol) and the mixture subjected to heating in a pre-heated oil
bath. The mixture was stirred at 70.degree. C. for 18 h and then
allowed to cool. The solvent was removed to give 158.8 g of the
desired intermediate (1) in 93.8% yield (based on
1-(4-bromophenyl)methanamine as limiting reagent).
Preparation of Intermediate 2: 6-Bromoisoquinolin-3-amine
##STR00050##
[0134] In a 3 L, three-neck round bottom flask (equipped with
magnetic stir bar, thermometer, addition funnel), charged conc.
sulfuric acid (1.12 L). While maintaining an internal temperature
of 20-25.degree. C. with an ice water bath, dropwise charged
N-(4-bromobenzyl)-2,2-diethoxyethanimidamide (158.8 g, 504 mmol).
After addition, removed bath and allowed to stir at ambient
temperature for 72 h.
[0135] A 12-L, 3-necked round bottom flask, equipped with a large
stirrer bar, dropping funnel and thermometer was charged with water
(5 L). The flask was placed in an IPA bath and cooled externally
with solid CO.sub.2 to an internal temperature of 8.degree. C. Over
a period of 13/4 h, the reaction mixture was added slowly to the
water, keeping the internal temperature between 0.degree. C. and
10.degree. C., resulting in a yellow suspension. With continued
cooling, a 12 M NaOH solution was added over a 4 h period, keeping
the internal temperature below 30.degree. C. A final pH of 9-10 was
reached (required 4.6 L, 12 M NaOH). Note that upon reaching
neutral pH, the suspension changed to a much darker yellow. The
suspension was filtered over a medium glass filter and the
remaining residue was washed repeatedly with a total of 4 L of
water to wash away precipitated Na-salts which resulted in a
significant decrease of the amount of solids on the filter. The
residue was dried in high vac at room temperature over KOH to give
143 g of a yellow powder. Elemental analysis showed 5.9 weight % of
Na which corresponds to 36.4 weight % of Na.sub.2SO.sub.4. This
material was used for further elaboration.
Preparation of Intermediate 3:
6-(1H-Pyrazol-4-yl)isoquinolin-3-amine
##STR00051##
[0137] A 3-L, three-necked rbf, equipped with a condenser,
thermometer and large stirrer bar was charged with DME (1 L) and a
2M Cs.sub.2CO.sub.3 (1 L, 10 eq). The two-phased system purged with
nitrogen under vigorous stirring for 45 min, followed by the
addition of 6-bromoisoquinolin-3-amine (44 g, 64 w % purity, 126
mmol), the commercially available boronate (50 g, 170 mmol), and
PdCl.sub.2(dppf), CH.sub.2Cl.sub.2 complex (10.6 g, 14.2 mmol,
Strem) and MeOH (2 mL). The nitrogen purge was discontinued and
replaced by a nitrogen in/outlet on top of the condenser. The
reaction mixture was heated to rfx (internal temperature 80.degree.
C.) for a period of 16 h and allowed to cool to room temperature.
The cooled reaction mixture appeared as a two-layer system with a
virtually colorless, aqueous layer and a dark organic layer in
which a light brown precipitate had formed. The reaction mixture
was filtered over a short path of Celite (pre-wetted with MeOH) and
the Celite was subsequently washed with DME (110 mL). Removal of
the solids improved visibility and the water layer could be readily
separated. The organic layer was further diluted with ethyl acetate
(700 mL) resulting in the separation of more solids which were
remove by short-path filtration over a fresh batch of Celite
(pre-wetted with MeOH). The filtrate was concentrated to a volume
of 30 mL and the formed solids were isolated by filtration and
washed with diethyl ether (40 mL) to give 4.8 g (11%) of the
desired product as a yellow solid.
[0138] An alternative procedure for the preparation is as follows:
To a 3-necked flask equipped with stirrer, nitrogen inlet and
internal thermometer was charged with 3-amino, 6-bromoisoquinoline
(6.0 g, 20.0 mmol),
2-(2',6'-dimethoxybiphenyl)dicyclohexylphosphine (S-Phos) (2.0 g,
3.0 mmol), thoroughly freshly degassed DME (200 mL), water (40 mL),
and Cs.sub.2CO.sub.3 (46.2 g, 142.0 mmol). The suspension was
placed under nitrogen in a pre-heated oil bath at 86.degree. C.
Meanwhile, a solution of
1-BOC-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyrazole (10.8
g, 36.0 mmol) in degassed DME (30 mL) was prepared and stored under
nitrogen. When the internal temperature of the suspension had
reached 84.degree. C., the Pd.sub.2(dba).sub.3 (2.8 g, 3.0 mmol)
was added, and quickly followed by dropwise addition of the
pyrazole boronate solution (via syringe over 5 min). The resulting
bi-phasic dark orange solution was stirred at 84.degree. C. for 20
mins. The flask was then placed in an ice bath to cool rapidly.
Once at ambient temperature, the mixture was filtered to remove
inorganic substance, washed with water (2.times.25 mL). Upon
reduction of the solution volume via evaporation the solid product
was filtered and collected. The light yellow product was washed
with ethyl ether 3 time (20 ml) to give a pale yellow solid
product. Yield: 6.1 g, 98.4%.

2-(5-methoxy-2-methyl-1H-indol-3-yl)-N-[6-(1H-pyrazol-4-yl)isoquinolin-3-y-
l]acetamide
##STR00052##
[0140] To a solution of 2-(5-methoxy-2-methyl-1H-indol-3-yl)acetic
acid (219.2 mg, 0.5 mmol) in 5 mL of anhydrous THF was added oxalyl
chloride (119.6 mg, 0.95 mmol), and 100 .mu.L of DMF also was
added. A effervescence occurred. Within 1-4 minutes the
effervescence stopped. The mixture was stirred for 30 minute at
room temperature, followed by addition of
6-(1H-Pyrazol-4-yl)-isoquinolin-3-ylamine in 5 mL of pyridine
(100.0 mg, 0.5 mmol). The reaction was stirred at the ambient
temperature over 16 hours as it was monitored by LC/MS. To the
reaction mixture was added K.sub.2CO.sub.3 (196.7 mg, 1.4 mmol) and
water (2 mL). The solution was heated to 70.degree. C. for 5 hours.
Removal of the solvents provided a crude mixture that was purified
by HPLC using H.sub.2O/CH.sub.3CN/0.1% acetic acid as a mobile
phase to give the title compound as a crystalline solid product

##STR00209##
[0191] To a solution of tetrahydrofuran-3-ol (337 mg, 3.83 mmol) in
THF (5 mL) was added NaH (153 mg, 60% disp. in oil, 3.83 mmol) and
the mix stirred at r.t. for 20 min., forming a pale suspension. To
this was added trans-4-[(7-fluoroquinazolin-2-yl)amino]cyclohexanol
(100 mg, 0.383 mmol) and a yellow suspension formed almost
immediately. The suspension was stirred at r.t. for 30 min then
heated to 45.degree. C. for 1 hour, then heated to 65.degree. C.
for 30 min then cooled to R.T. overnight. The liquors were
concentrated and diluted with water (10 mL) and EtOAc (25 mL) and
shaken vigorously. The aq. was removed and the organics washed with
water (10 mL), brine (10 mL), dried over MgSO.sub.4, filtered and
stripped to an oil. Purified by prep TLC eluting with EtOAc to
yield the title compound as a white foam, 36 mg, 29%. .sup.1H NMR

Biological activity
[0329] The percentage of inhibition (at 1 .mu.M or 10 .mu.M unless
otherwise stated) and/or the Ki (in nM unless otherwise stated) for
the compounds exemplified in the present application were obtained
according to the protocol below:
[0330] % Inhibition and K.sub.i Determination
[0331] A coupled spectrophotometric assay, coupling JNK1.alpha.1
activity to the oxidation of .beta.-NADH to NAD+ through the action
of pyruvate kinase (PK) and lactic dehydrogenase (LDH), was used to
determine the potency (percent inhibition at 1 or 10 .mu.M or
K.sub.i) of compounds against JNK1.alpha.1 (Genbank Accession
Number: L26318). The final reaction conditions were as follows: 20
mM HEPES pH 7.6, 10 mM MgCl.sub.2, 1 mM DTT, 200 .mu.M peptide
substrate (KRELVEPLTPSGEAPNQALLR), 300 .mu.M NADH, 500 .mu.M PEP
(phophoenolpyruvate), 9-10 units/mL LDH, 8-12 units/mL PK, 40 nM
JNK1.alpha.1.sub.--364nHis (catalytic domain containing amino acids
1-364 and N-terminal hexahistidine tag, previously activated by
MKK4 and MKK7beta in vitro), 0-100 .mu.M test compound, 2.5% DMSO,
and 50 .mu.M ATP (2.5.times. Km). The reaction was monitored by
following the decrease in absorbance at 340 nm. The initial
reaction rate was determined by the slope of the change in
absorbance. To calculate percent inhibition the rate of the
reaction in the presence of 1 or 10 .mu.M compound was compared to
the rate of the reaction with only DMSO multiplied by 100 percent.
Note, the background rate of the above reaction in the presence of
10 .mu.M PHA-00738186 was subtracted from all rates. To calculate
the K.sub.i, the reaction rates (with the background subtracted)
were plotted vs. the compound concentration (0-100 .mu.M) and fit
to the tight binding for competitive inhibitors (Morrison) equation
(see below).
Formula

0.5)*(Vm*A/(Km+A)/(2*Eo)) [0332] Parameters: Eo, Ki, A, Km, Vo
[0333] Y is initial reaction velocity; [0334] X is inhibitor
concentration; [0335] A is [ATP]; [0336] Ki is inhibition constant;
[0337] Vm is Vmax; [0338] Eo is total (initial) enzyme
concentration; [0339] Km is ATP Km;
[0340] The compounds were prepared in 100% DMSO at a 40.times.
concentration. For percent inhibition experiments this would be 400
or 40 .mu.M for 10 and 1 .mu.M final concentration, respectively.
For the Ki determination 3.times. serial dilutions were made
starting at 4 mM (100 .mu.M at 1.times.) in DMSO. A total of 11
concentrations were used for the analysis. The compounds were added
to the reaction plate first. Next, a solution containing the HEPES,
MgCl.sub.2, DTT, peptide substrate, NADH, PEP, PK/LDH enzyme, and
JNK1.alpha.1.sub.--364nHis enzyme was added to the assay plate. The
plate was incubated at room temperature for 15 minutes. Then the
plate was warmed to 30.degree. C. for 5 minutes. The reaction was
initiated with the addition of ATP. The reaction was run in a plate
reader at 30.degree. C. for 20 minutes with absorbance readings
made about every 10 seconds.
JNK1.alpha.1 364nHis Purification Procedure
Growth and Induction Conditions
[0341] BL21 (DE3) cells containing JNK1.alpha.1.sub.--364nHis
vector were grown at 37.degree. C. until optical density
(OD.sub.600) was between 0.6 to 0.8. Expression was induced by
addition of isopropylthiogalactoside (IPTG) to a final
concentration of 0.1-0.2 mM and incubated at 23.degree. C.
overnight. The cells were harvested at 5000 rpm for 15 minutes at
4.degree. C. The cell pellet can be stored at -80.degree. C. for
future purification.
Purification Procedure
[0342] 1. Cell pellet (1 L culture) was resuspended with lysis
buffer at 5-10 mL/wet cell pellet. The maximum and minimum volumes
were 350 mL and 60 mL.
TABLE-US-00016 [0342] Lysis Buffer 1 L 25 mM Tris-HCl, pH8.0 25 mL
of 1M 300 mM NaCl 60 mL of 5M 14 mM .beta.-ME (add fresh) 1 mL of
14M stock 20 mM Imidazole 5 mL of 4M dH.sub.2O 909 mL
[0343] The lysis buffer was filtered before use. [0344] 2. The cell
were lyzed with microfluidizer (three times) and ultracentrifuged
at 40,000 rpm for 45 minutes at 4.degree. C. The supernatant was
transferred to a chilled flask. A 20 ul aliquot was saved for gel
analysis. [0345] 3. Ni-NTA column (23 mL) lines were rinsed with
lysis buffer. The column (23 mL) was washed with 160 mL of lysis
buffer at 5 mL/min. [0346] 4. The supernatant was loaded onto
Ni-NTA column at 4 mL/min. [0347] 5. The unbound was washed with
160 mL of lysis buffer at 5 mL/min. [0348] 6. The protein was
eluted with imidazole gradient (from 20 mM to 0.5M). The elution
buffer was prepared as follows:
TABLE-US-00017 [0348] Elution Buffer 250 mL 25 mM Tris-HCl, pH7.5
6.25 mL of 1M 300 mM NaCl 15 mL of 5M 14 mM .beta.-ME (add fresh)
0.25 mL of 14M stock 0.5M Imidazole 31.25 mL of 4M dH.sub.2O 197.25
mL
[0349] The elution buffer was filtered before use [0350] 7. The
elution settings were as follows. The record speed was set @1.0
mm/min.

[0351] At the end of the elution the record speed was returned to
0.1 mm/min. Referring to the template above, BP means break point,
% B means % buffer grading, FR means flow rate, and FS means
fraction size. [0352] 8. The peak fractions were pooled. A 40 ul
aliquot was saved for gel analysis. [0353] 9. The sample was
concentrated down to 4-6 mL with ultrafiltration cell under
nitrogen. [0354] 10. While sample was being concentrated, the
Superdex 200 column was washed with 450 mL Superdex buffer at 2
mL/min. The Superdex buffer was prepared as follows:
TABLE-US-00019 [0354] Superdex buffer 1 L 25 mM Hepes pH 7.5, 25 mL
5% Glycerol 100 mL 10 mM DTT 1.54 g 50 mM NaCl 10 mL dH.sub.2O 865
mL
[0355] To prepare the protein that was used for the assay, Dundee
buffer was used for Superdex column. The Dundee buffer was prepared
as follows:
TABLE-US-00020 Dundee Buffer 1 L 50 mM Tris Cl pH 7.5, 50 mL 270 mM
Sucrose 92.4 g 150 mM NaCl 30 mL 0.1 mM EGTA 1 mL 0.1% bMe 1 mL

[0356] 11. The concentrated sample was transferred to pre-chilled
1.5 mL tubes and spinned at max for 10 minutes in cold room. The
supernatant was transferred to 50 mL chilled tube. [0357] 12. The
sample was injected (total volume equals total sample loop volume
plus 0.3 mL) to pre-washed loop (4-6 mL). A 5 ul aliquat was saved
of the remaining sample for SDS-PAGE (a detergent). [0358] 13. The
protein was eluted overnight according to the following settings.
The record speed was set at 0.2 mm/min.

[0359] At the completion of the elution, the record speed was
returned to 0.1 mm/min. Referring to the template above, BP means
break point, FR means flow rate, FS means fraction size, I means
inject, and L means load. [0360] 14. The peak fractions were pooled
and the pool concentration was measured. The protein was
concentrated down to 7-8 mg/mL in hepes buffer protein. Aliquots of
the protein were placed into chilled 0.5 mL tubes at 100 ul/tube,
which were then snapped frozen in liquid nitrogen and stored at
-80.degree. C.
[0361] The following procedure to regenerate the Ni-NTA and the
Superdex 200 columns was used:
Ni-NTA Column
[0362] The Ni-NTA column was washed with 80 mL of dH.sub.2O at 5
mL/min. Next it was washed with 80 mL of 0.1M EDTA, pH8.0 at 5
mL/min. The flow was collected through in flask for proper
disposal. The column was further washed with 150 mL of dH.sub.2O at
5 mL/min. and charged with 60 mL of 100 mM NiCl.sub.2 at 5 mL/min.
The flow was collected through in the same waste flask. The column
was then washed with 60 mL of dH.sub.2O at 5 mL/min and the flow
was again collected through in the same waste flask. The column was
then washed with 160 mL of dH.sub.2O at 5 mL/min.
Superdex 200 Column
[0363] The Superdex 200 column was washed with 700 mL of filtered
dH.sub.2O at 2 mL/min.
[0364] The data obtained from the compounds of the invention
according to the above protocol are tabulated below. The column
with "#" heading refers to compound number as exemplified in the
Examples section. The column with "Ki" heading refers to Ki (in
nM). The column with "% Inhibition" heading refers to percent
inhibition of JNK-1 at 1 .mu.M or 10 .mu.M (in %) unless otherwise
stated. ND refers to no data was taken.
