Description
FIELD OF THE INVENTION
[0001] The present invention relates to compounds that may be used
to inhibit Mitogen-Activated Protein kinases (also known as MEK and
MAPK/ERK kinases), such as Mitogen-Activated Protein Kinase Kinase
1 (also known as MAPKK1, MAPK/ERK Kinase 1, and MEK1) and
Mitogen-Activated Protein Kinase Kinase 2 (also known as MAPKK2,
MAPK/ERK Kinase 2, and MEK2), as well as compositions of matter,
kits and articles of manufacture comprising these compounds. The
invention also relates to methods for inhibiting MEK and/or ERK
activity, and treatment methods using compounds according to the
present invention. In addition, the invention relates to methods of
making the compounds of the present invention, as well as
intermediates useful in such methods.
BACKGROUND OF THE INVENTION
[0002] The mitogen activated protein kinase (MAPK) signaling
pathways are involved in cellular events such as growth,
differentiation and stress responses (J. Biol. Chem. (1993) 268,
14553-14556). Four parallel MAPK pathways have been identified to
date: ERK1/ERK2, JNK, p38 and ERK5. These pathways are linear
kinase cascades in that MAPKKK phosphorylates and activates MAPKK,
and MAPKK phosphorylates and activates MAPK. To date, seven MAPKK
homologs (MEK1, MEK2, MKK3, MKK4/SEK, MEK5, MKK6, and MKK7) and
four MAPK families (ERK1/2, JNK, p38, and ERK5) have been
identified. Activation of these pathways regulates the activity of
a number of substrates through phosphorylation. These substrates
include: transcription factors such as TCF, c-myc, ATF2 and the
AP-1 components, fos and Jun; cell surface components EGF-R;
cytosolic components including PHAS-I, p90.sup.rsk, cPLA.sub.2 and
c-Raf-1; and cytoskeleton components such as tau and MAP2. MAPK
signaling cascades are involved in controlling cellular processes
including proliferation, differentiation, apoptosis, and stress
responses.
[0003] Of the known MAPK signaling pathways, the RAF-MEK-ERK
pathway mediates proliferative and anti-apoptotic signaling from
growth factors and oncogenic factors such as Ras and Raf mutant
phenotypes that promote tumor growth, progression, and metastasis.
By virtue of its central role in mediating the transmission of
growth-promoting signals from multiple growth factor receptors, the
RAF-MEK-ERK pathway provides molecular targets with potentially
broad therapeutic applications in, for example, cancerous and
noon-cancerous hyperproliferative disorders, immunomodulation and
inflammation.
[0004] MEK occupies a strategic downstream position in the
RAF-MEK-ERK pathway catalyzing the phosphorylation of its MAPK
substrates, ERK1 and ERK2. Anderson et al. "Requirement for
integration of signals from two distinct phosphorylation pathways
for activation of MAP kinase." Nature 1990, v.343, pp. 651-653. In
the ERK pathway, MAPKK corresponds with MEK (MAP kinase ERK Kinase)
and the MAPK corresponds with ERK (Extracellular Regulated Kinase).
No substrates for MEK have been identified other than ERK1 and
ERK2. Seger et al. "Purification and characterization of
mitogen-activated protein kinase activator(s) from epidermal growth
factor-stimulated A431 cells." J. Biol. Chem., 1992, v. 267, pp.
14373-14381. This tight selectivity, in addition to the unique
ability to act as a dual-specificity kinase, is consistent with
MEK's central role in integration of signals into the MAPK pathway.
MEK also appears to associate strongly with MAP kinase prior to
phosphorylating it, suggesting that phosphorylation of MAP kinase
by MEK may require a prior strong interaction between the two
proteins. Both this requirement and the unusual specificity of MEK
are suggestive that it may have enough difference in its mechanism
of action to other protein kinases that selective inhibitors of
MEK, possibly operating through allosteric mechanisms rather than
through the usual blockade of the ATP binding site, may be
found.
[0005] Constitutive action of MAPKs has been reported in >30% of
primary tumor cell lines including cell lines derived from colon,
lung, breast, pancreas, ovary, and kidney. Hoshino et al.
"Constitutive activation of the 41-/43-kDa mitogen-activated
protein kinase signaling pathway in human tumors." Oncogene, 1999,
v. 18, pp. 813-822. Higher concentrations of active MAPK/ERK
(pMAPK/pERK) have been detected in tumor tissue as compared to
normal adjacent tissue. Sivaraman et al. "Hyperexpression of
mitogen-activated protein kinase in human breast cancer." J. Clin.
Invest., 1997, v. 99, pp. 1478-1483.
[0006] There is a continued need to find new therapeutic agents to
treat human diseases. The MAPK/ERK kinases, specifically but not
limited to MEK1 and MEK2, are especially attractive targets for the
discovery of new therapeutics due to their important role in
cancerous hyperproliferative disorders (e.g., brain, lung, squamous
cell, bladder, gastric, pancreatic, breast, head, neck, renal,
kidney, ovarian, prostate, colorectal, prostate, colon, epidermoid,
esophageal, testicular, gynecological or thyroid cancer;
non-cancerous hyperproliferative disorders (e.g., benign
hyperplasia of the skin (e.g., psoriasis), restenosis, and benign
prostatic hypertrophy (BPH)); pancreatitis; kidney disease; pain;
preventing blastocyte implantation; treating diseases related to
vasculogenesis or angiogenesis (e.g., tumor angiogenesis, acute and
chronic inflammatory disease such as rheumatoid arthritis,
atherosclerosis, inflammatory bowel disease, skin diseases such as
psoriasis, excema, and scleroderma, diabetes, diabetic retinopathy,
retinopathy of prematurity, age-related macular degeneration,
hemangioma, glioma, melanoma, Kaposi's sarcoma and ovarian, breast,
lung, pancreatic, prostate, colon and epidermoid cancer); asthma;
neutrophil chemotaxis; septic shock; T-cell mediated diseases where
immune suppression would be of value (e.g., the prevention of organ
transplant rejection, graft versus host disease, lupus
erythematosus, multiple sclerosis, and rheumatoid arthritis);
conditions where neutrophil influx drives tissue destruction (e.g.,
reperfusion injury in myocardial infarction and stroke and
inflammatory arthritis); atherosclerosis; inhibition of
keratinocyte responses to growth factor cocktails; and other
diseases.

sulfones.
[0084] "Therapeutically effective amount" means that amount which,
when administered to an animal for treating a disease, is
sufficient to effect such treatment for the disease.

[0086] "Thioalkyl" means an alkyl, as defined above, except where
one or more of the carbon atoms forming the alkyl chain are
replaced with sulfur atoms (--S-- or --S--R, wherein R is hydrogen

[0088] "Treatment" or "treating" means any administration of a
compound of the present invention and includes:
[0089] (1) preventing the disease from occurring in an animal which
may be predisposed to the disease but does not yet experience or
display the pathology or symptomatology of the disease,
[0090] (2) inhibiting the disease in an animal that is experiencing
or displaying the pathology or symptomatology of the diseased
(i.e., arresting further development of the pathology and/or
symptomatology), or
[0091] (3) ameliorating the disease in an animal that is
experiencing or displaying the pathology or symptomatology of the
diseased (i.e., reversing the pathology and/or symptomatology).
[0092] It is noted in regard to all of the definitions provided
herein that the definitions should be interpreted as being open
ended in the sense that further substituents beyond those specified
may be included. Hence, a C.sub.1 alkyl indicates that there is one
carbon atom but does not indicate what are the substituents on the
carbon atom. Hence, a (C.sub.1)alkyl comprises methyl (i.e.,
--CH.sub.3) as well as --CRR'R'' where R, R', and R'' may each
independently be hydrogen or a further substituent where the atom
attached to the carbon is a heteroatom or cyano. Hence, CF.sub.3,
CH.sub.2OH and CH.sub.2CN, for example, are all (C.sub.1)alkyls.
Similarly, terms such as alkylamino and the like comprise
dialkylamino and the like.
[0093] A compound having a formula that is represented with a
dashed bond is intended to include the formulae optionally having
zero, one or more double bonds, as exemplified and shown below:
##STR00002##
[0094] In addition, atoms making up the compounds of the present
invention are intended to include all isotopic forms of such atoms.
Isotopes, as used herein, include those atoms having the same
atomic number but different mass numbers. By way of general example
and without limitation, isotopes of hydrogen include tritium and
deuterium, and isotopes of carbon include .sup.13C and
.sup.14C.
DETAILED DESCRIPTION OF THE INVENTION
[0095] The present invention relates to compounds, compositions,
kits and articles of manufacture that may be used to inhibit
Mitogen-Activated Protein Kinases (referred to herein as MEK) and,
in particular, MAPK/ERK Kinase 1 (referred to herein as MEK1)
and/or MAPK/ERK Kinase 2 (referred to herein as MEK2).
[0096] MEK belongs to the protein kinase family of enzymes. The
mitogen-activated protein kinase (MAPK) pathways are evolutionarily
conserved from yeast to man and respond to a variety of
extracellular signals to induce cell differentiation and
proliferation. The extracellular-regulated kinase (ERK) cascade is
one of three major MAPK signaling pathways and is the predominant
cascade that controls cell proliferation, migration, division, and
differentiation (Schaeffer, H. J., and Weber, M. J. (1999) Mol.
Cell. Biol. 19, 2435-2444). In this pathway, binding of GTP to the
Ras protein initiates a three protein kinase cascade, which leads
to ERK activation through the intervening protein kinases Raf-1 and
MEK1/2. The MEK1/2 kinases are dual-specificity threonine/tyrosine
kinases that activate the downstream ERK kinase by phosphorylating
specific ERK threonine and tyrosine residues, and are themselves
activated by phosphorylation of MEK serine residues by the upstream
RAF kinase. MEK1 and MEK2 share a high degree of amino acid
sequence similarity, particularly in their kinase domains, and both
are capable of phosphorylating ERK (Zheng, C-F., and Guan, K.
(1993) J. Biol. Chem. 268, 11435-11439).
[0097] Multiple studies have linked the RAF/MEK/ERK signaling
pathway to the growth and survival of many diverse human tumors
including, but not limited to cancers of the colon, pancreas
ovaries, and non-small-cell lung cancers (reviewed in:
Sebolt-Leopold, J. S. and Herrera R. (2004) Nature Reviews: Cancer,
4, 937-947). For these reasons there has been considerable interest
in developing small molecule pharmaceutical inhibitors of this
pathway.
[0098] It is noted that the compounds of the present invention may
also possess inhibitory activity for other protein kinase family
members and thus may be used to address disease states associated
with these other family members.
Crystal Structure of MEK2
[0099] Takeda San Diego, Inc. solved the crystal structure of MEK2.
Knowledge of the crystal structure was used to guide the design of
the inhibitors provided herein.
[0100] The overall architecture of the MEK proteins resembles the
conserved, two domain protein kinase fold, consisting of a large
C-terminal comprised mostly of an .alpha.-helical domain and a
smaller N-terminal lobe comprised primarily of a .beta.-sheet. The
N-lobe typically contains a single .alpha.-helix termed the Control
or C-helix which influences the productive binding of nucleotides
at the active region, which is located at the cleft between the two
domains. Additionally, productive binding of nucleotide and
substrates can be dependent upon an Activation Loop, or A-Loop,
which is in an extended conformation when active, but often in a
folded-back inactive conformation that at least partially occludes
the active region. Phosphorylation of specific residues within the
A-Loop can help stabilise the active, extended conformation. Common
kinase inhibitory mechanisms typically target structural
alterations within the C-Helix or A Loop.

Salts, Hydrates, and Prodrugs of MEK Inhibitors
[0421] It should be recognized that the compounds of the present
invention may be present and optionally administered in the form of
salts, hydrates and prodrugs that are converted in vivo into the
compounds of the present invention. For example, it is within the
scope of the present invention to convert the compounds of the
present invention into and use them in the form of their
pharmaceutically acceptable salts derived from various organic and
inorganic acids and bases in accordance with procedures well known
in the art.
[0422] When the compounds of the present invention possess a free
base form, the compounds can be prepared as a pharmaceutically
acceptable acid addition salt by reacting the free base form of the
compound with a pharmaceutically acceptable inorganic or organic
acid, e.g., hydrohalides such as hydrochloride, hydrobromide,
hydroiodide; other mineral acids and their corresponding salts such
as sulfate, nitrate, phosphate, etc.; and alkyl and
monoarylsulfonates such as ethanesulfonate, toluenesulfonate and
benzenesulfonate; and other organic acids and their corresponding
salts such as acetate, tartrate, maleate, succinate, citrate,
benzoate, salicylate and ascorbate. Further acid addition salts of
the present invention include, but are not limited to: adipate,
alginate, arginate, aspartate, bisulfate, bisulfite, bromide,
butyrate, camphorate, camphorsulfonate, caprylate, chloride,
chlorobenzoate, cyclopentanepropionate, digluconate,
dihydrogenphosphate, dinitrobenzoate, dodecylsulfate, fumarate,
galacterate (from mucic acid), galacturonate, glucoheptaoate,
gluconate, glutamate, glycerophosphate, hemisuccinate, hemisulfate,
heptanoate, hexanoate, hippurate, hydrochloride, hydrobromide,
hydroiodide, 2-hydroxyethanesulfonate, iodide, isethionate,
iso-butyrate, lactate, lactobionate, malate, malonate, mandelate,
metaphosphate, methanesulfonate, methylbenzoate,
monohydrogenphosphate, 2-naphthalenesulfonate, nicotinate, nitrate,
oxalate, oleate, pamoate, pectinate, persulfate, phenylacetate,
3-phenylpropionate, phosphate, phosphonate and phthalate. It should
be recognized that the free base forms will typically differ from
their respective salt forms somewhat in physical properties such as
solubility in polar solvents, but otherwise the salts are
equivalent to their respective free base forms for the purposes of
the present invention.
[0423] When the compounds of the present invention possess a free
acid form, a pharmaceutically acceptable base addition salt can be
prepared by reacting the free acid form of the compound with a
pharmaceutically acceptable inorganic or organic base. Examples of
such bases are alkali metal hydroxides including potassium, sodium
and lithium hydroxides; alkaline earth metal hydroxides such as
barium and calcium hydroxides; alkali metal alkoxides, e.g.,
potassium ethanolate and sodium propanolate; and various organic
bases such as ammonium hydroxide, piperidine, diethanolamine and
N-methylglutamine. Also included are the aluminum salts of the
compounds of the present invention. Further base salts of the
present invention include, but are not limited to: copper, ferric,
ferrous, lithium, magnesium, manganic, manganous, potassium, sodium
and zinc salts. Organic base salts include, but are not limited to,
salts of primary, secondary and tertiary amines, substituted amines
including naturally occurring substituted amines, cyclic amines and
basic ion exchange resins, e.g., arginine, betaine, caffeine,
chloroprocaine, choline, N,N'-dibenzylethylenediamine(benzathine),
dicyclohexylamine, diethanolamine, 2-diethylaminoethanol,
2-dimethylaminoethanol, ethanolamine, ethylenediamine,
N-ethylmorpholine, N-ethylpiperidine, glucamine, glucosamine,
histidine, hydrabamine, iso-propylamine, lidocaine, lysine,
meglumine, N-methyl-D-glucamine, morpholine, piperazine,
piperidine, polyamine resins, procaine, purines, theobromine,
triethanolamine, triethylamine, trimethylamine, tripropylamine and
tris-(hydroxymethyl)-methylamine (tromethamine). It should be
recognized that the free acid forms will typically differ from
their respective salt forms somewhat in physical properties such as
solubility in polar solvents, but otherwise the salts are
equivalent to their respective free acid forms for the purposes of
the present invention.
[0424] Compounds of the present invention that comprise basic
nitrogen-containing groups may be quaternized with such agents as
(C.sub.1-4) alkyl halides, e.g., methyl, ethyl, iso-propyl and
tert-butyl chlorides, bromides and iodides; di(C.sub.1-4) alkyl
sulfates, e.g., dimethyl, diethyl and diamyl sulfates;
(C.sub.10-18) alkyl halides, e.g., decyl, dodecyl, lauryl, myristyl
and stearyl chlorides, bromides and iodides; and aryl(C.sub.1-4)
alkyl halides, e.g., benzyl chloride and phenethyl bromide. Such
salts permit the preparation of both water-soluble and oil-soluble
compounds of the present invention.
[0425] N-oxides of compounds according to the present invention can
be prepared by methods known to those of ordinary skill in the art.
For example, N-oxides can be prepared by treating an unoxidized
form of the compound with an oxidizing agent (e.g.,
trifluoroperacetic acid, permaleic acid, perbenzoic acid, peracetic
acid, meta-chloroperoxybenzoic acid, or the like) in a suitable
inert organic solvent (e.g., a halogenated hydrocarbon such as
dichloromethane) at approximately 0.degree. C. Alternatively, the
N-oxides of the compounds can be prepared from the N-oxide of an
appropriate starting material.
[0426] Prodrug derivatives of compounds according to the present
invention can be prepared by modifying substituents of compounds of
the present invention that are then converted in vivo to a
different substituent. It is noted that in many instances, the
prodrugs themselves also fall within the scope of the range of
compounds according to the present invention. For example, prodrugs
can be prepared by reacting a compound with a carbamylating agent
(e.g., 1,1-acyloxyalkylcarbonochloridate, para-nitrophenyl
carbonate, or the like) or an acylating agent. Further examples of
methods of making prodrugs are described in Saulnier et al. (1994),
Bioorganic and Medicinal Chemistry Letters, Vol. 4, p. 1985.
[0427] Protected derivatives of compounds of the present invention
can also be made. Examples of techniques applicable to the creation
of protecting groups and their removal can be found in T. W.
Greene, Protecting Groups in Organic Synthesis, 3.sup.rd edition,
John Wiley & Sons, Inc. 1999.
[0428] Compounds of the present invention may also be conveniently
prepared, or formed during the process of the invention, as
solvates (e.g., hydrates). Hydrates of compounds of the present
invention may be conveniently prepared by recrystallization from an
aqueous/organic solvent mixture, using organic solvents such as
dioxin, tetrahydrofuran or methanol.
[0429] A "pharmaceutically acceptable salt", as used herein, is
intended to encompass any compound according to the present
invention that is utilized in the form of a salt thereof,
especially where the salt confers on the compound improved
pharmacokinetic properties as compared to the free form of compound
or a different salt form of the compound. The pharmaceutically
acceptable salt form may also initially confer desirable
pharmacokinetic properties on the compound that it did not
previously possess, and may even positively affect the
pharmacodynamics of the compound with respect to its therapeutic
activity in the body. An example of a pharmacokinetic property that
may be favorably affected is the manner in which the compound is
transported across cell membranes, which in turn may directly and
positively affect the absorption, distribution, biotransformation
and excretion of the compound. While the route of administration of
the pharmaceutical composition is important, and various
anatomical, physiological and pathological factors can critically
affect bioavailability, the solubility of the compound is usually
dependent upon the character of the particular salt form thereof,
which it utilized. One of skill in the art will appreciate that an
aqueous solution of the compound will provide the most rapid
absorption of the compound into the body of a subject being
treated, while lipid solutions and suspensions, as well as solid
dosage forms, will result in less rapid absorption of the
compound.
Preparation of MEK Inhibitors
[0430] Various methods may be developed for synthesizing compounds
according to the present invention. Representative methods for
synthesizing these compounds are provided in the Examples. It is
noted, however, that compounds of the present invention may also be
synthesized by other synthetic routes that others may devise.
[0431] It will be readily recognized that certain compounds
according to the present invention have atoms with linkages to
other atoms that confer a particular stereochemistry to the
compound (e.g., chiral centers). It is recognized that synthesis of
compounds according to the present invention may result in the
creation of mixtures of different stereoisomers (i.e., enantiomers
and diastereomers). Unless a particular stereochemistry is
specified, recitation of a compound is intended to encompass all of
the different possible stereoisomers.
[0432] Various methods for separating mixtures of different
stereoisomers are known in the art. For example, a racemic mixture
of a compound may be reacted with an optically active resolving
agent to form a pair of diastereoisomeric compounds. The
diastereomers may then be separated in order to recover the
optically pure enantiomers. Dissociable complexes may also be used
to resolve enantiomers (e.g., crystalline diastereoisomeric salts).
Diastereomers typically have sufficiently distinct physical
properties (e.g., melting points, boiling points, solubilities,
reactivity, etc.) that they can be readily separated by taking
advantage of these dissimilarities. For example, diastereomers can
typically be separated by chromatography or by
separation/resolution techniques based upon differences in
solubility. A more detailed description of techniques that can be
used to resolve stereoisomers of compounds from their racemic
mixture can be found in Jean Jacques Andre Collet, Samuel H. Wilen,
Enantiomers, Racemates and Resolutions, John Wiley & Sons, Inc.
(1981).
Compositions Comprising MEK Inhibitors
[0433] A wide variety of compositions and administration methods
may be used in conjunction with the compounds of the present
invention. Such compositions may include, in addition to the
compounds of the present invention, conventional pharmaceutical
excipients, and other conventional, pharmaceutically inactive
agents. Additionally, the compositions may include active agents in
addition to the compounds of the present invention. These
additional active agents may include additional compounds according
to the invention, and/or one or more other pharmaceutically active
agents.
[0434] The compositions may be in gaseous, liquid, semi-liquid or
solid form, formulated in a manner suitable for the route of
administration to be used. For oral administration, capsules and
tablets are typically used. For parenteral administration,
reconstitution of a lyophilized powder, prepared as described
herein, is typically used.
[0435] Compositions comprising compounds of the present invention
may be administered or coadministered orally, parenterally,
intraperitoneally, intravenously, intraarterially, transdermally,
sublingually, intramuscularly, rectally, transbuccally,
intranasally, liposomally, via inhalation, vaginally,
intraoccularly, via local delivery (for example by catheter or
stent), subcutaneously, intraadiposally, intraarticularly, or
intrathecally. The compounds and/or compositions according to the
invention may also be administered or coadministered in slow
release dosage forms.
[0436] The MEK inhibitors and compositions comprising them may be
administered or coadministered in any conventional dosage form.
Co-administration in the context of this invention is intended to
mean the administration of more than one therapeutic agent, one of
which includes a MEK inhibitor, in the course of a coordinated
treatment to achieve an improved clinical outcome. Such
co-administration may also be coextensive, that is, occurring
during overlapping periods of time.
[0437] Solutions or suspensions used for parenteral, intradermal,
subcutaneous, or topical application may optionally include one or
more of the following components: a sterile diluent, such as water
for injection, saline solution, fixed oil, polyethylene glycol,
glycerine, propylene glycol or other synthetic solvent;
antimicrobial agents, such as benzyl alcohol and methyl parabens;
antioxidants, such as ascorbic acid and sodium bisulfate; chelating
agents, such as ethylenediaminetetraacetic acid (EDTA); buffers,
such as acetates, citrates and phosphates; agents for the
adjustment of tonicity such as sodium chloride or dextrose, and
agents for adjusting the acidity or alkalinity of the composition,
such as alkaline or acidifying agents or buffers like carbonates,
bicarbonates, phosphates, hydrochloric acid, and organic acids like
acetic and citric acid. Parenteral preparations may optionally be
enclosed in ampules, disposable syringes or single or multiple dose
vials made of glass, plastic or other suitable material.
[0438] When compounds according to the present invention exhibit
insufficient solubility, methods for solubilizing the compounds may
be used. Such methods are known to those of skill in this art, and
include, but are not limited to, using cosolvents, such as
dimethylsulfoxide (DMSO), using surfactants, such as TWEEN, or
dissolution in aqueous sodium bicarbonate. Derivatives of the
compounds, such as prodrugs of the compounds may also be used in
formulating effective pharmaceutical compositions.
[0439] Upon mixing or adding compounds according to the present
invention to a composition, a solution, suspension, emulsion or the
like may be formed. The form of the resulting composition will
depend upon a number of factors, including the intended mode of
administration, and the solubility of the compound in the selected
carrier or vehicle. The effective concentration needed to
ameliorate the disease being treated may be empirically
determined.
[0440] Compositions according to the present invention are
optionally provided for administration to humans and animals in
unit dosage forms, such as tablets, capsules, pills, powders, dry
powders for inhalers, granules, sterile parenteral solutions or
suspensions, and oral solutions or suspensions, and oil-water
emulsions containing suitable quantities of the compounds,
particularly the pharmaceutically acceptable salts, preferably the
sodium salts, thereof. The pharmaceutically therapeutically active
compounds and derivatives thereof are typically formulated and
administered in unit-dosage forms or multiple-dosage forms.
Unit-dose forms, as used herein, refers to physically discrete
units suitable for human and animal subjects and packaged
individually as is known in the art. Each unit-dose contains a
predetermined quantity of the therapeutically active compound
sufficient to produce the desired therapeutic effect, in
association with the required pharmaceutical carrier, vehicle or
diluent. Examples of unit-dose forms include ampoules and syringes
individually packaged tablet or capsule. Unit-dose forms may be
administered in fractions or multiples thereof. A multiple-dose
form is a plurality of identical unit-dosage forms packaged in a
single container to be administered in segregated unit-dose form.
Examples of multiple-dose forms include vials, bottles of tablets
or capsules or bottles of pint or gallons. Hence, multiple dose
form is a multiple of unit-doses that are not segregated in
packaging.
[0441] In addition to one or more compounds according to the
present invention, the composition may comprise: a diluent such as
lactose, sucrose, dicalcium phosphate, or carboxymethylcellulose; a
lubricant, such as magnesium stearate, calcium stearate and talc;
and a binder such as starch, natural gums, such as gum
acaciagelatin, glucose, molasses, polyinylpyrrolidine, celluloses
and derivatives thereof, povidone, crospovidones and other such
binders known to those of skill in the art. Liquid pharmaceutically
administrable compositions can, for example, be prepared by
dissolving, dispersing, or otherwise mixing an active compound as
defined above and optional pharmaceutical adjuvants in a carrier,
such as, for example, water, saline, aqueous dextrose, glycerol,
glycols, ethanol, and the like, to form a solution or suspension.
If desired, the pharmaceutical composition to be administered may
also contain minor amounts of auxiliary substances such as wetting
agents, emulsifying agents, or solubilizing agents, pH buffering
agents and the like, for example, acetate, sodium citrate,
cyclodextrine derivatives, sorbitan monolaurate, triethanolamine
sodium acetate, triethanolamine oleate, and other such agents.
Actual methods of preparing such dosage forms are known in the art,
or will be apparent, to those skilled in this art; for example, see
Remington's Pharmaceutical Sciences, Mack Publishing Company,
Easton, Pa., 15th Edition, 1975. The composition or formulation to
be administered will, in any event, contain a sufficient quantity
of a inhibitor of the present invention to reduce MEK activity in
vivo, thereby treating the disease state of the subject.
[0442] Dosage forms or compositions may optionally comprise one or
more compounds according to the present invention in the range of
0.005% to 100% (weight/weight) with the balance comprising
additional substances such as those described herein. For oral
administration, a pharmaceutically acceptable composition may
optionally comprise any one or more commonly employed excipients,
such as, for example pharmaceutical grades of mannitol, lactose,
starch, magnesium stearate, talcum, cellulose derivatives, sodium
crosscarmellose, glucose, sucrose, magnesium carbonate, sodium
saccharin, talcum. Such compositions include solutions,
suspensions, tablets, capsules, powders, dry powders for inhalers
and sustained release formulations, such as, but not limited to,
implants and microencapsulated delivery systems, and biodegradable,
biocompatible polymers, such as collagen, ethylene vinyl acetate,
polyanhydrides, polyglycolic acid, polyorthoesters, polylactic acid
and others. Methods for preparing these formulations are known to
those skilled in the art. The compositions may optionally contain
0.01%-100% (weight/weight) of one or more MEK inhibitors,
optionally 0.1-95%, and optionally 1-95%.
[0443] Salts, preferably sodium salts, of the inhibitors may be
prepared with carriers that protect the compound against rapid
elimination from the body, such as time release formulations or
coatings. The formulations may further include other active
compounds to obtain desired combinations of properties.

[0457] If oral administration is desired, the salt of the compound
may optionally be provided in a composition that protects it from
the acidic environment of the stomach. For example, the composition
can be formulated in an enteric coating that maintains its
integrity in the stomach and releases the active compound in the
intestine. The composition may also be formulated in combination
with an antacid or other such ingredient.
[0458] When the dosage unit form is a capsule, it may optionally
additionally comprise a liquid carrier such as a fatty oil. In
addition, dosage unit forms may optionally additionally comprise
various other materials that modify the physical form of the dosage
unit, for example, coatings of sugar and other enteric agents.

sprinkle, chewing gum or the like. A syrup may optionally comprise,
in addition to the active compounds, sucrose as a sweetening agent
and certain preservatives, dyes and colorings and flavors.
[0460] The compounds of the present invention may also be mixed
with other active materials that do not impair the desired action,
or with materials that supplement the desired action, such as
antacids, H2 blockers, and diuretics. For example, if a compound is
used for treating asthma or hypertension, it may be used with other
bronchodilators and antihypertensive agents, respectively.
[0461] Examples of pharmaceutically acceptable carriers that may be
included in tablets comprising compounds of the present invention
include, but are not limited to binders, lubricants, diluents,
disintegrating agents, coloring agents, flavoring agents, and
wetting agents. Enteric-coated tablets, because of the
enteric-coating, resist the action of stomach acid and dissolve or
disintegrate in the neutral or alkaline intestines. Sugar-coated
tablets may be compressed tablets to which different layers of
pharmaceutically acceptable substances are applied. Film-coated
tablets may be compressed tablets that have been coated with
polymers or other suitable coating. Multiple compressed tablets may
be compressed tablets made by more than one compression cycle
utilizing the pharmaceutically acceptable substances previously
mentioned. Coloring agents may also be used in tablets. Flavoring
and sweetening agents may be used in tablets, and are especially
useful in the formation of chewable tablets and lozenges.

FD and C dyes, and mixtures thereof.
[0475] Particular examples of flavoring agents that may be used
include natural flavors extracted from plants such fruits, and
synthetic blends of compounds that produce a pleasant taste
sensation.
[0476] For a solid dosage form, the solution or suspension, in for
example propylene carbonate, vegetable oils or triglycerides, is
preferably encapsulated in a gelatin capsule. Such solutions, and
the preparation and encapsulation thereof, are disclosed in U.S.
Pat. Nos. 4,328,245; 4,409,239; and 4,410,545. For a liquid dosage
form, the solution, e.g., for example, in a polyethylene glycol,
may be diluted with a sufficient quantity of a pharmaceutically
acceptable liquid carrier, e.g., water, to be easily measured for
administration.
[0477] Alternatively, liquid or semi-solid oral formulations may be
prepared by dissolving or dispersing the active compound or salt in
vegetable oils, glycols, triglycerides, propylene glycol esters
(e.g., propylene carbonate) and other such carriers, and
encapsulating these solutions or suspensions in hard or soft
gelatin capsule shells. Other useful formulations include those set
forth in U.S. Pat. Nos. Re 28,819 and 4,358,603.
Injectables, Solutions, and Emulsions
[0478] The present invention is also directed to compositions
designed to administer the compounds of the present invention by
parenteral administration, generally characterized by subcutaneous,
intramuscular or intravenous injection. Injectables may be prepared
in any conventional form, for example as liquid solutions or
suspensions, solid forms suitable for solution or suspension in
liquid prior to injection, or as emulsions.
[0479] Examples of excipients that may be used in conjunction with
injectables according to the present invention include, but are not
limited to water, saline, dextrose, glycerol or ethanol. The
injectable compositions may also optionally comprise minor amounts
of non-toxic auxiliary substances such as wetting or emulsifying
agents, pH buffering agents, stabilizers, solubility enhancers, and
other such agents, such as for example, sodium acetate, sorbitan
monolaurate, triethanolamine oleate and cyclodextrins. Implantation
of a slow-release or sustained-release system, such that a constant
level of dosage is maintained (see, e.g., U.S. Pat. No. 3,710,795)
is also contemplated herein. The percentage of active compound
contained in such parenteral compositions is highly dependent on
the specific nature thereof, as well as the activity of the
compound and the needs of the subject.
[0480] Parenteral administration of the formulations includes
intravenous, subcutaneous and intramuscular administrations.
Preparations for parenteral administration include sterile
solutions ready for injection, sterile dry soluble products, such
as the lyophilized powders described herein, ready to be combined
with a solvent just prior to use, including hypodermic tablets,
sterile suspensions ready for injection, sterile dry insoluble
products ready to be combined with a vehicle just prior to use and
sterile emulsions. The solutions may be either aqueous or
nonaqueous.
[0481] When administered intravenously, examples of suitable
carriers include, but are not limited to physiological saline or
phosphate buffered saline (PBS), and solutions containing
thickening and solubilizing agents, such as glucose, polyethylene
glycol, and polypropylene glycol and mixtures thereof.
[0482] Examples of pharmaceutically acceptable carriers that may
optionally be used in parenteral preparations include, but are not
limited to aqueous vehicles, nonaqueous vehicles, antimicrobial
agents, isotonic agents, buffers, antioxidants, local anesthetics,
suspending and dispersing agents, emulsifying agents, sequestering
or chelating agents and other pharmaceutically acceptable
substances.
[0483] Examples of aqueous vehicles that may optionally be used
include Sodium Chloride Injection, Ringers Injection, Isotonic
Dextrose Injection, Sterile Water Injection, Dextrose and Lactated
Ringers Injection.
[0484] Examples of nonaqueous parenteral vehicles that may
optionally be used include fixed oils of vegetable origin,
cottonseed oil, corn oil, sesame oil and peanut oil.
[0485] Antimicrobial agents in bacteriostatic or fungistatic
concentrations may be added to parenteral preparations,
particularly when the preparations are packaged in multiple-dose
containers and thus designed to be stored and multiple aliquots to
be removed. Examples of antimicrobial agents that may be used
include phenols or cresols, mercurials, benzyl alcohol,
chlorobutanol, methyl and propyl p-hydroxybenzoic acid esters,
thimerosal, benzalkonium chloride and benzethonium chloride.
[0486] Examples of isotonic agents that may be used include sodium
chloride and dextrose. Examples of buffers that may be used include
phosphate and citrate. Examples of antioxidants that may be used
include sodium bisulfate. Examples of local anesthetics that may be
used include procaine hydrochloride. Examples of suspending and
dispersing agents that may be used include sodium
carboxymethylcellulose, hydroxypropyl methylcellulose and
polyvinylpyrrolidone. Examples of emulsifying agents that may be
used include Polysorbate 80 (TWEEN 80). A sequestering or chelating
agent of metal ions includes EDTA.
[0487] Pharmaceutical carriers may also optionally include ethyl
alcohol, polyethylene glycol and propylene glycol for water
miscible vehicles and sodium hydroxide, hydrochloric acid, citric
acid or lactic acid for pH adjustment.
[0488] The concentration of an inhibitor in the parenteral
formulation may be adjusted so that an injection administers a
pharmaceutically effective amount sufficient to produce the desired
pharmacological effect. The exact concentration of an inhibitor
and/or dosage to be used will ultimately depend on the age, weight
and condition of the patient or animal as is known in the art.
[0489] Unit-dose parenteral preparations may be packaged in an
ampoule, a vial or a syringe with a needle. All preparations for
parenteral administration should be sterile, as is know and
practiced in the art.
[0490] Injectables may be designed for local and systemic
administration. Typically a therapeutically effective dosage is
formulated to contain a concentration of at least about 0.1% w/w up
to about 90% w/w or more, preferably more than 1% w/w of the MEK
inhibitor to the treated tissue(s). The inhibitor may be
administered at once, or may be divided into a number of smaller
doses to be administered at intervals of time. It is understood
that the precise dosage and duration of treatment will be a
function of the location of where the composition is parenterally
administered, the carrier and other variables that may be
determined empirically using known testing protocols or by
extrapolation from in vivo or in vitro test data. It is to be noted
that concentrations and dosage values may also vary with the age of
the individual treated. It is to be further understood that for any
particular subject, specific dosage regimens may need to be
adjusted over time according to the individual need and the
professional judgment of the person administering or supervising
the administration of the formulations. Hence, the concentration
ranges set forth herein are intended to be exemplary and are not
intended to limit the scope or practice of the claimed
formulations.
[0491] The MEK inhibitor may optionally be suspended in micronized
or other suitable form or may be derivatized to produce a more
soluble active product or to produce a prodrug. The form of the
resulting mixture depends upon a number of factors, including the
intended mode of administration and the solubility of the compound
in the selected carrier or vehicle. The effective concentration is
sufficient for ameliorating the symptoms of the disease state and
may be empirically determined.
Lyophilized Powders
[0492] The compounds of the present invention may also be prepared
as lyophilized powders, which can be reconstituted for
administration as solutions, emulsions and other mixtures. The
lyophilized powders may also be formulated as solids or gels.
[0493] Sterile, lyophilized powder may be prepared by dissolving
the compound in a sodium phosphate buffer solution containing
dextrose or other suitable excipient. Subsequent sterile filtration
of the solution followed by lyophilization under standard
conditions known to those of skill in the art provides the desired
formulation. Briefly, the lyophilized powder may optionally be
prepared by dissolving dextrose, sorbitol, fructose, corn syrup,
xylitol, glycerin, glucose, sucrose or other suitable agent, about
1-20%, preferably about 5 to 15%, in a suitable buffer, such as
citrate, sodium or potassium phosphate or other such buffer known
to those of skill in the art at, typically, about neutral pH. Then,
a MEK inhibitor is added to the resulting mixture, preferably above
room temperature, more preferably at about 30-35.degree. C., and
stirred until it dissolves. The resulting mixture is diluted by
adding more buffer to a desired concentration. The resulting
mixture is sterile filtered or treated to remove particulates and
to insure sterility, and apportioned into vials for lyophilization.
Each vial may contain a single dosage or multiple dosages of the
inhibitor.
Topical Administration
[0494] The compounds of the present invention may also be
administered as topical mixtures. Topical mixtures may be used for
local and systemic administration. The resulting mixture may be a
solution, suspension, emulsions or the like and are formulated as
creams, gels, ointments, emulsions, solutions, elixirs, lotions,
suspensions, tinctures, pastes, foams, aerosols, irrigations,
sprays, suppositories, bandages, dermal patches or any other
formulations suitable for topical administration.
[0495] The MEK inhibitors may be formulated as aerosols for topical
application, such as by inhalation (see, U.S. Pat. Nos. 4,044,126,
4,414,209, and 4,364,923, which describe aerosols for delivery of a
steroid useful for treatment of inflammatory diseases, particularly
asthma). These formulations for administration to the respiratory
tract can be in the form of an aerosol or solution for a nebulizer,
or as a microfine powder for insufflation, alone or in combination
with an inert carrier such as lactose. In such a case, the
particles of the formulation will typically have diameters of less
than 50 microns, preferably less than 10 microns.
[0496] The inhibitors may also be formulated for local or topical
application, such as for topical application to the skin and mucous
membranes, such as in the eye, in the form of gels, creams, and
lotions and for application to the eye or for intracisternal or
intraspinal application. Topical administration is contemplated for
transdermal delivery and also for administration to the eyes or
mucosa, or for inhalation therapies. Nasal solutions of the MEK
inhibitor alone or in combination with other pharmaceutically
acceptable excipients can also be administered.
Formulations for Other Routes of Administrations
[0497] Depending upon the disease state being treated, other routes
of administration, such as topical application, transdermal
patches, and rectal administration, may also be used. For example,
pharmaceutical dosage forms for rectal administration are rectal
suppositories, capsules and tablets for systemic effect. Rectal
suppositories are used herein mean solid bodies for insertion into
the rectum that melt or soften at body temperature releasing one or
more pharmacologically or therapeutically active ingredients.
Pharmaceutically acceptable substances utilized in rectal
suppositories are bases or vehicles and agents to raise the melting
point. Examples of bases include cocoa butter (theobroma oil),
glycerin-gelatin, carbowax, (polyoxyethylene glycol) and
appropriate mixtures of mono-, di- and triglycerides of fatty
acids. Combinations of the various bases may be used. Agents to
raise the melting point of suppositories include spermaceti and
wax. Rectal suppositories may be prepared either by the compressed
method or by molding. The typical weight of a rectal suppository is
about 2 to 3 gm. Tablets and capsules for rectal administration may
be manufactured using the same pharmaceutically acceptable
substance and by the same methods as for formulations for oral
administration.
Examples of Formulations
[0498] The following are particular examples of oral, intravenous
and tablet formulations that may optionally be used with compounds
of the present invention. It is noted that these formulations may
be varied depending on the particular compound being used and the
indication for which the formulation is going to be used.
TABLE-US-00001 ORAL FORMULATION Compound of the Present Invention

Water for Injection q.s. to 1.0 mL TABLET FORMULATION Compound of
the Present Invention 1% Microcrystalline Cellulose 73% Stearic
Acid 25% Colloidal Silica .sup. 1%.
Kits Comprising MEK Inhibitors
[0499] The invention is also directed to kits and other articles of
manufacture for treating diseases associated with MEK. It is noted
that diseases are intended to cover all conditions for which the
MEK possess activity that contributes to the pathology and/or
symptomology of the condition.
[0500] In one embodiment, a kit is provided that comprises a
composition comprising at least one inhibitor of the present
invention in combination with instructions. The instructions may
indicate the disease state for which the composition is to be
administered, storage information, dosing information and/or
instructions regarding how to administer the composition. The kit
may also comprise packaging materials. The packaging material may
comprise a container for housing the composition. The kit may also
optionally comprise additional components, such as syringes for
administration of the composition. The kit may comprise the
composition in single or multiple dose forms.
[0501] In another embodiment, an article of manufacture is provided
that comprises a composition comprising at least one inhibitor of
the present invention in combination with packaging materials. The
packaging material may comprise a container for housing the
composition. The container may optionally comprise a label
indicating the disease state for which the composition is to be
administered, storage information, dosing information and/or
instructions regarding how to administer the composition. The kit
may also optionally comprise additional components, such as
syringes for administration of the composition. The kit may
comprise the composition in single or multiple dose forms.
[0502] It is noted that the packaging material used in kits and
articles of manufacture according to the present invention may form
a plurality of divided containers such as a divided bottle or a
divided foil packet. The container can be in any conventional shape
or form as known in the art which is made of a pharmaceutically
acceptable material, for example a paper or cardboard box, a glass
or plastic bottle or jar, a re-sealable bag (for example, to hold a
"refill" of tablets for placement into a different container), or a
blister pack with individual doses for pressing out of the pack
according to a therapeutic schedule. The container that is employed
will depend on the exact dosage form involved, for example a
conventional cardboard box would not generally be used to hold a
liquid suspension. It is feasible that more than one container can
be used together in a single package to market a single dosage
form. For example, tablets may be contained in a bottle that is in
turn contained within a box. Typically the kit includes directions
for the administration of the separate components. The kit form is
particularly advantageous when the separate components are
preferably administered in different dosage forms (e.g., oral,
topical, transdermal and parenteral), are administered at different
dosage intervals, or when titration of the individual components of
the combination is desired by the prescribing physician.
[0503] One particular example of a kit according to the present
invention is a so-called blister pack. Blister packs are well known
in the packaging industry and are being widely used for the
packaging of pharmaceutical unit dosage forms (tablets, capsules,
and the like). Blister packs generally consist of a sheet of
relatively stiff material covered with a foil of a preferably
transparent plastic material. During the packaging process recesses
are formed in the plastic foil. The recesses have the size and
shape of individual tablets or capsules to be packed or may have
the size and shape to accommodate multiple tablets and/or capsules
to be packed. Next, the tablets or capsules are placed in the
recesses accordingly and the sheet of relatively stiff material is
sealed against the plastic foil at the face of the foil which is
opposite from the direction in which the recesses were formed. As a
result, the tablets or capsules are individually sealed or
collectively sealed, as desired, in the recesses between the
plastic foil and the sheet. Preferably the strength of the sheet is
such that the tablets or capsules can be removed from the blister
pack by manually applying pressure on the recesses whereby an
opening is formed in the sheet at the place of the recess. The
tablet or capsule can then be removed via said opening.
[0504] Another specific embodiment of a kit is a dispenser designed
to dispense the daily doses one at a time in the order of their
intended use. Preferably, the dispenser is equipped with a
memory-aid, so as to further facilitate compliance with the
regimen. An example of such a memory-aid is a mechanical counter
that indicates the number of daily doses that has been dispensed.
Another example of such a memory-aid is a battery-powered
micro-chip memory coupled with a liquid crystal readout, or audible
reminder signal which, for example, reads out the date that the
last daily dose has been taken and/or reminds one when the next
dose is to be taken.
Dosage, Host and Safety
[0505] The compounds of the present invention are stable and can be
used safely. In particular, the compounds of the present invention
are useful as MEK inhibitors for a variety of subjects (e.g.,
humans, non-human mammals and non-mammals). The optimal dose may
vary depending upon such conditions as, for example, the type of
subject, the body weight of the subject, the route of
administration, and specific properties of the particular compound
being used. In general, the daily dose for oral administration to
an adult (body weight of about 60 kg) is about 1 to 1000 mg, about
3 to 300 mg, or about 10 to 200 mg. It will be appreciated that the
daily dose can be given in a single administration or in multiple
(e.g., 2 or 3) portions a day.
Combination Therapy
[0506] A wide variety therapeutic agents may have a therapeutic
additive or synergistic effect with MEK inhibitors according to the
present invention. Such therapeutic agents may addictively or
synergistically combine with the MEK inhibitors to inhibit
undesirable cell growth, such as inappropriate cell growth
resulting in undesirable benign conditions or tumor growth.
[0507] In one embodiment, a method is provided for treating a cell
proliferative disease state comprising treating cells with a
compound according to the present invention in combination with an
anti-proliferative agent, wherein the cells are treated with the
compound according to the present invention before, at the same
time, and/or after the cells are treated with the
anti-proliferative agent, referred to herein as combination
therapy. It is noted that treatment of one agent before another is
referred to herein as sequential therapy, even if the agents are
also administered together. It is noted that combination therapy is
intended to cover when agents are administered before or after each
other (sequential therapy) as well as when the agents are
administered at the same time.
[0508] Examples of therapeutic agents that may be used in
combination with MEK inhibitors include, but are not limited to,
anticancer agents, alkylating agents, antibiotic agents,
antimetabolic agents, hormonal agents, plant-derived agents, and
biologic agents.
[0509] Alkylating agents are polyfunctional compounds that have the
ability to substitute alkyl groups for hydrogen ions. Examples of
alkylating agents include, but are not limited to,
bischloroethylamines (nitrogen mustards, e.g. chlorambucil,
cyclophosphamide, ifosfamide, mechlorethamine, melphalan, uracil
mustard), aziridines (e.g. thiotepa), alkyl alkone sulfonates (e.g.
busulfan), nitrosoureas (e.g. carmustine, lomustine, streptozocin),
nonclassic alkylating agents (altretamine, dacarbazine, and
procarbazine), platinum compounds (carboplastin and cisplatin).
These compounds react with phosphate, amino, hydroxyl, sulfihydryl,
carboxyl, and imidazole groups. Under physiological conditions,
these drugs ionize and produce positively charged ion that attach
to susceptible nucleic acids and proteins, leading to cell cycle
arrest and/or cell death. Combination therapy including a MEK
inhibitor and an alkylating agent may have therapeutic synergistic
effects on cancer and reduce sides affects associated with these
chemotherapeutic agents.
[0510] Antibiotic agents are a group of drugs that produced in a
manner similar to antibiotics as a modification of natural
products. Examples of antibiotic agents include, but are not
limited to, anthracyclines (e.g. doxorubicin, daunorubicin,
epirubicin, idarubicin and anthracenedione), mitomycin C,
bleomycin, dactinomycin, plicatomycin. These antibiotic agents
interferes with cell growth by targeting different cellular
components. For example, anthracyclines are generally believed to
interfere with the action of DNA topoisomerase II in the regions of
transcriptionally active DNA, which leads to DNA strand scissions.
Bleomycin is generally believed to chelate iron and forms an
activated complex, which then binds to bases of DNA, causing strand
scissions and cell death. Combination therapy including a MEK
inhibitor and an antibiotic agent may have therapeutic synergistic
effects on cancer and reduce sides affects associated with these
chemotherapeutic agents.
[0511] Antimetabolic agents are a group of drugs that interfere
with metabolic processes vital to the physiology and proliferation
of cancer cells. Actively proliferating cancer cells require
continuous synthesis of large quantities of nucleic acids,
proteins, lipids, and other vital cellular constituents. Many of
the antimetabolites inhibit the synthesis of purine or pyrimidine
nucleosides or inhibit the enzymes of DNA replication. Some
antimetabolites also interfere with the synthesis of
ribonucleosides and RNA and/or amino acid metabolism and protein
synthesis as well. By interfering with the synthesis of vital
cellular constituents, antimetabolites can delay or arrest the
growth of cancer cells. Examples of antimetabolic agents include,
but are not limited to, fluorouracil (5-FU), floxuridine (5-FUdR),
methotrexate, leucovorin, hydroxyurea, thioguanine (6-TG),
mercaptopurine (6-MP), cytarabine, pentostatin, fludarabine
phosphate, cladribine (2-CDA), asparaginase, and gemcitabine.
Combination therapy including a MEK inhibitor and a antimetabolic
agent may have therapeutic synergistic effects on cancer and reduce
sides affects associated with these chemotherapeutic agents.
[0512] Hormonal agents are a group of drug that regulate the growth
and development of their target organs. Most of the hormonal agents
are sex steroids and their derivatives and analogs thereof, such as
estrogens, androgens, and progestins. These hormonal agents may
serve as antagonists of receptors for the sex steroids to down
regulate receptor expression and transcription of vital genes.
Examples of such hormonal agents are synthetic estrogens (e.g.
diethylstibestrol), antiestrogens (e.g. tamoxifen, toremifene,
fluoxymesterol and raloxifene), antiandrogens (bicalutamide,
nilutamide, flutamide), aromatase inhibitors (e.g.,
aminoglutethimide, anastrozole and tetrazole), ketoconazole,
goserelin acetate, leuprolide, megestrol acetate and mifepristone.
Combination therapy including a MEK inhibitor and a hormonal agent
may have therapeutic synergistic effects on cancer and reduce sides
affects associated with these chemotherapeutic agents.
[0513] Plant-derived agents are a group of drugs that are derived
from plants or modified based on the molecular structure of the
agents. Examples of plant-derived agents include, but are not
limited to, vinca alkaloids (e.g., vincristine, vinblastine,
vindesine, vinzolidine and vinorelbine), podophyllotoxins (e.g.,
etoposide (VP-16) and teniposide (VM-26)), taxanes (e.g.,
paclitaxel and docetaxel). These plant-derived agents generally act
as antimitotic agents that bind to tubulin and inhibit mitosis.
Podophyllotoxins such as etoposide are believed to interfere with
DNA synthesis by interacting with topoisomerase II, leading to DNA
strand scission. Combination therapy including a MEK inhibitor and
a plant-derived agent may have therapeutic synergistic effects on
cancer and reduce sides affects associated with these
chemotherapeutic agents.
[0514] Biologic agents are a group of biomolecules that elicit
cancer/tumor regression when used alone or in combination with
chemotherapy and/or radiotherapy. Examples of biologic agents
include, but are not limited to, immuno-modulating proteins such as
cytokines, monoclonal antibodies against tumor antigens, tumor
suppressor genes, and cancer vaccines. Combination therapy
including a MEK inhibitor and a biologic agent may have therapeutic
synergistic effects on cancer, enhance the patient's immune
responses to tumorigenic signals, and reduce potential sides
affects associated with this chemotherapeutic agent.
[0515] Cytokines possess profound immunomodulatory activity. Some
cytokines such as interleukin-2 (IL-2, aldesleukin) and interferon
have demonstrated antitumor activity and have been approved for the
treatment of patients with metastatic renal cell carcinoma and
metastatic malignant melanoma. IL-2 is a T-cell growth factor that
is central to T-cell-mediated immune responses. The selective
antitumor effects of IL-2 on some patients are believed to be the
result of a cell-mediated immune response that discriminate between
self and nonself. Examples of interleukins that may be used in
conjunction with MEK inhibitor include, but are not limited to,
interleukin 2 (IL-2), and interleukin 4 (IL-4), interleukin 12
(IL-12).
[0516] Interferon include more than 23 related subtypes with
overlapping activities, all of the IFN subtypes within the scope of
the present invention. IFN has demonstrated activity against many
solid and hematologic malignancies, the later appearing to be
particularly sensitive.
[0517] Other cytokines that may be used in conjunction with a MEK
inhibitor include those cytokines that exert profound effects on
hematopoiesis and immune functions. Examples of such cytokines
include, but are not limited to erythropoietin, granulocyte-CSF
(filgrastin), and granulocyte, macrophage-CSF (sargramostim). These
cytokines may be used in conjunction with a MEK inhibitor to reduce
chemotherapy-induced myelopoietic toxicity.
[0518] Other immuno-modulating agents other than cytokines may also
be used in conjunction with a MEK inhibitor to inhibit abnormal
cell growth. Examples of such immuno-modulating agents include, but
are not limited to bacillus Calmette-Guerin, levamisole, and
octreotide, a long-acting octapeptide that mimics the effects of
the naturally occurring hormone somatostatin.
[0519] Monoclonal antibodies against tumor antigens are antibodies
elicited against antigens expressed by tumors, preferably
tumor-specific antigens. For example, monoclonal antibody
HERCEPTIN.RTM. (Trastruzumab) is raised against human epidermal
growth factor receptor2 (HER2) that is overexpressed in some breast
tumors including metastatic breast cancer. Overexpression of HER2
protein is associated with more aggressive disease and poorer
prognosis in the clinic. HERCEPTIN.RTM. is used as a single agent
for the treatment of patients with metastatic breast cancer whose
tumors over express the HER2 protein. Combination therapy including
MEK inhibitor and HERCEPTIN.RTM. may have therapeutic synergistic
effects on tumors, especially on metastatic cancers.
[0520] Another example of monoclonal antibodies against tumor
antigens is RITUXAN.RTM. (Rituximab) that is raised against CD20 on
lymphoma cells and selectively deplete normal and malignant
CD20.sup.+ pre-B and mature B cells. RITUXAN.RTM. is used as single
agent for the treatment of patients with relapsed or refractory
low-grade or follicular, CD20+, B cell non-Hodgkin's lymphoma.
Combination therapy including MEK inhibitor and RITUXAN.RTM. may
have therapeutic synergistic effects not only on lymphoma, but also
on other forms or types of malignant tumors.
[0521] Tumor suppressor genes are genes that function to inhibit
the cell growth and division cycles, thus preventing the
development of neoplasia. Mutations in tumor suppressor genes cause
the cell to ignore one or more of the components of the network of
inhibitory signals, overcoming the cell cycle check points and
resulting in a higher rate of controlled cell growth--cancer.
Examples of the tumor suppressor genes include, but are not limited
to, DPC-4, NF-1, NF-2, RB, p53, WT1, BRCA1 and BRCA2.
[0522] DPC-4 is involved in pancreatic cancer and participates in a
cytoplasmic pathway that inhibits cell division. NF-1 codes for a
protein that inhibits Ras, a cytoplasmic inhibitory protein. NF-1
is involved in neurofibroma and pheochromocytomas of the nervous
system and myeloid leukemia. NF-2 encodes a nuclear protein that is
involved in meningioma, schwanoma, and ependymoma of the nervous
system. RB codes for the pRB protein, a nuclear protein that is a
major inhibitor of cell cycle. RB is involved in retinoblastoma as
well as bone, bladder, small cell lung and breast cancer. P53 codes
for p53 protein that regulates cell division and can induce
apoptosis. Mutation and/or inaction of p53 is found in a wide
ranges of cancers. WT1 is involved in Wilms tumor of the kidneys.
BRCA1 is involved in breast and ovarian cancer, and BRCA2 is
involved in breast cancer. The tumor suppressor gene can be
transferred into the tumor cells where it exerts its tumor
suppressing functions. Combination therapy including a MEK
inhibitor and a tumor suppressor may have therapeutic synergistic
effects on patients suffering from various forms of cancers.
[0523] Cancer vaccines are a group of agents that induce the body's
specific immune response to tumors. Most of cancer vaccines under
research and development and clinical trials are tumor-associated
antigens (TAAs). TAA are structures (i.e. proteins, enzymes or
carbohydrates) which are present on tumor cells and relatively
absent or diminished on normal cells. By virtue of being fairly
unique to the tumor cell, TAAs provide targets for the immune
system to recognize and cause their destruction. Example of TAAs
include, but are not limited to gangliosides (GM2), prostate
specific antigen (PSA), alpha-fetoprotein (AFP), carcinoembryonic
antigen (CEA) (produced by colon cancers and other adenocarcinomas,
e.g. breast, lung, gastric, and pancreas cancer s), melanoma
associated antigens (MART-1, gp100, MAGE 1,3 tyrosinase),
papillomavirus E6 and E7 fragments, whole cells or portions/lysates
of antologous tumor cells and allogeneic tumor cells.
[0524] An adjuvant may be used to augment the immune response to
TAAs. Examples of adjuvants include, but are not limited to,
bacillus Calmette-Guerin (BCG), endotoxin lipopolysaccharides,
keyhole limpet hemocyanin (GKLH), interleukin-2 (IL-2),
granulocyte-macrophage colony-stimulating factor (GM-CSF) and
cytoxan, a chemotherapeutic agent which is believe to reduce
tumor-induced suppression when given in low doses.
[0525] Further examples of therapeutic agents that may be used in
combination with MEK inhibitors include, but are not limited to,
P13/Akt signaling inhibitors. Examples of P13/Akt inhibitors that
may be used in combination with MEK inhibitors include, but are not
limited to, human epidermal growth factor receptor (HER2)
inhibitors. Examples of HER2 inhibitors include, but are not
limited to, Herceptin.RTM. (Trastruzumab) and Tykerb.RTM.
(Lapatinib). Tykerb.RTM., a small molecule that can be administered
orally, inhibits the tyrosine kinase components of ErbB1 and ErbB2
receptors. Stimulation of ErbB1 and ErbB2 is associated with cell
proliferation and with multiple processes involved in tumor
progression, invasion, and metastasis. Overexpression of these
receptors has been reported in a variety of human tumors and is
associated with poor prognosis and reduced overall survival.
[0526] Still further examples of therapeutic agents that may be
used in combination with MEK inhibitors include, but are not
limited to, histone deacetylase (HDAC) inhibitors. Examples of HDAC
inhibitors that may be used in combination with MEK inhibitors
include, but are not limited to, suberoylanilide hydroxamic acid
(SAHA).
EXAMPLES
Preparation of Mek Inhibitors
[0527] Various methods may be developed for synthesizing compounds
according to the present invention. Representative methods for
synthesizing these compounds are provided in the Examples. It is
noted, however, that the compounds of the present invention may
also be synthesized by other synthetic routes that others may
devise.
[0528] It will be readily recognized that certain compounds
according to the present invention have atoms with linkages to
other atoms that confer a particular stereochemistry to the
compound (e.g., chiral centers). It is recognized that synthesis of
compounds according to the present invention may result in the
creation of mixtures of different stereoisomers (i.e., enantiomers
and diastereomers). Unless a particular stereochemistry is
specified, recitation of a compound is intended to encompass all of
the different possible stereoisomers.
[0529] Various methods for separating mixtures of different
stereoisomers are known in the art. For example, a racemic mixture
of a compound may be reacted with an optically active resolving
agent to form a pair of diastereoisomeric compounds. The
diastereomers may then be separated in order to recover the
optically pure enantiomers. Dissociable complexes may also be used
to resolve enantiomers (e.g., crystalline diastereoisomeric salts).
Diastereomers typically have sufficiently distinct physical
properties (e.g., melting points, boiling points, solubilities,
reactivity, etc.) and can be readily separated by taking advantage
of these dissimilarities. For example, diastereomers can typically
be separated by chromatography or by separation/resolution
techniques based upon differences in solubility. A more detailed
description of techniques that can be used to resolve stereoisomers
of compounds from their racemic mixture can be found in Jean
Jacques Andre Collet, Samuel H. Wilen, Enantiomers, Racemates and
Resolutions, John Wiley & Sons, Inc. (1981).
[0530] Compounds according to the present invention can also be
prepared as a pharmaceutically acceptable acid addition salt by
reacting the free base form of the compound with a pharmaceutically
acceptable inorganic or organic acid. Alternatively, a
pharmaceutically acceptable base addition salt of a compound can be
prepared by reacting the free acid form of the compound with a
pharmaceutically acceptable inorganic or organic base. Inorganic
and organic acids and bases suitable for the preparation of the
pharmaceutically acceptable salts of compounds are set forth in the
definitions section of this Application. Alternatively, the salt
forms of the compounds can be prepared using salts of the starting
materials or intermediates.
[0531] The free acid or free base forms of the compounds can be
prepared from the corresponding base addition salt or acid addition
salt form. For example, a compound in an acid addition salt form
can be converted to the corresponding free base by treating with a
suitable base (e.g., ammonium hydroxide solution, sodium hydroxide,
and the like). A compound in a base addition salt form can be
converted to the corresponding free acid by treating with a
suitable acid (e.g., hydrochloric acid, etc).
[0532] The N-oxides of compounds according to the present invention
can be prepared by methods known to those of ordinary skill in the
art. For example, N-oxides can be prepared by treating an
unoxidized form of the compound with an oxidizing agent (e.g.,
trifluoroperacetic acid, permaleic acid, perbenzoic acid, peracetic
acid, meta-chloroperoxybenzoic acid, or the like) in a suitable
inert organic solvent (e.g., a halogenated hydrocarbon such as
dichloromethane) at approximately 0.degree. C. Alternatively, the
N-oxides of the compounds can be prepared from the N-oxide of an
appropriate starting material.
[0533] Compounds in an unoxidized form can be prepared from
N-oxides of compounds by treating with a reducing agent (e.g.,
sulfur, sulfur dioxide, triphenyl phosphine, lithium borohydride,
sodium borohydride, phosphorus trichloride, tribromide, or the
like) in an suitable inert organic solvent (e.g., acetonitrile,
ethanol, aqueous dioxane, or the like) at 0 to 80.degree. C.
[0534] Prodrug derivatives of the compounds can be prepared by
methods known to those of ordinary skill in the art (e.g., for
further details see Saulnier et al. (1994), Bioorganic and
Medicinal Chemistry Letters, Vol. 4, p. 1985). For example,
appropriate prodrugs can be prepared by reacting a non-derivatized
compound with a suitable carbamylating agent (e.g.,
1,1-acyloxyalkylcarbonochloridate, para-nitrophenyl carbonate, or
the like).
[0535] Protected derivatives of the compounds can be made by
methods known to those of ordinary skill in the art. A detailed
description of the techniques applicable to the creation of
protecting groups and their removal can be found in T. W. Greene,
Protecting Groups in Organic Synthesis, 3.sup.rd edition, John
Wiley & Sons, Inc. 1999.
[0536] Compounds according to the present invention may be
conveniently prepared, or formed during the process of the
invention, as solvates (e.g., hydrates). Hydrates of compounds of
the present invention may be conveniently prepared by
recrystallization from an aqueous/organic solvent mixture, using
organic solvents such as dioxin, tetrahydrofuran or methanol.
[0537] Compounds according to the present invention can also be
prepared as their individual stereoisomers by reacting a racemic
mixture of the compound with an optically active resolving agent to
form a pair of diastereoisomeric compounds, separating the
diastereomers and recovering the optically pure enantiomer. While
resolution of enantiomers can be carried out using covalent
diastereomeric derivatives of compounds, dissociable complexes are
preferred (e.g., crystalline diastereoisomeric salts).
Diastereomers have distinct physical properties (e.g., melting
points, boiling points, solubilities, reactivity, etc.) and can be
readily separated by taking advantage of these dissimilarities. The
diastereomers can be separated by chromatography or, preferably, by
separation/resolution techniques based upon differences in
solubility. The optically pure enantiomer is then recovered, along
with the resolving agent, by any practical means that would not
result in racemization. A more detailed description of the
techniques applicable to the resolution of stereoisomers of
compounds from their racemic mixture can be found in Jean Jacques
Andre Collet, Samuel H. Wilen, Enantiomers, Racemates and
Resolutions, John Wiley & Sons, Inc. (1981).

to provide Compound B. Coupling of Compound B with an aniline
using, for example, LDA or BuLi at -78-0.degree. C., or under
microwave heating conditions at 50-200.degree. C., provides
Compound C. Compound C is then treated with phenyl chloroformate
and a base, such as Et.sub.3N or pyridine, to give Compound D.
Finally, displacement of the phenol group with an amine under
conventional heating or microwave heating conditions both at
50-150.degree. C., gives compounds of the present invention

[0554] Chiral components can be separated and purified using any of
a variety of techniques known to those skilled in the art. For
example, chiral components can be purified using supercritical
fluid chromatography (SFC). In one particular variation, chiral
analytical SFC/MS analyses are conducted using a Berger analytical
SFC system (AutoChem, Newark, Del.) which consists of a Berger SFC
dual pump fluid control module with a Berger FCM 1100/1200
supercritical fluid pump and FCM 1200 modifier fluid pump, a Berger
TCM 2000 oven, and an Alcott 718 autosampler. The integrated system
can be controlled by BI-SFC Chemstation software version 3.4.
Detection can be accomplished with a Waters ZQ 2000 detector
operated in positive mode with an ESI interface and a scan range
from 200-800 Da with 0.5 second per scan. Chromatographic
separations can be performed on a ChiralPak AD-H, ChiralPak AS-H,
ChiralCel OD-H, or ChiralCel OJ-H column (5.mu., 4.6.times.250 mm;
Chiral Technologies, Inc. West Chester, Pa.) with 10 to 40%
methanol as the modifier and with or without ammonium acetate (10
mM). Any of a variety of flow rates can be utilized including, for
example, 1.5 or 3.5 mL/min with an inlet pressure set at 100 bar.
Additionally, a variety of sample injection conditions can be used
including, for example, sample injections of either 5 or 104 in
methanol at 0.1 mg/mL in concentration.
[0555] In another variation, preparative chiral separations are
performed using a Berger MultiGram II SFC purification system. For
example, samples can be loaded onto a ChiralPak AD column
(21.times.250 mm, 10.mu.). In particular variations, the flow rate
for separation can be 70 mL/min, the injection volume up to 2 mL,
and the inlet pressure set at 130 bar. Stacked injections can be
applied to increase the efficiency.

Biological Testing
[0689] The activity of compounds as MEK inhibitors may be assayed
in vitro, in vivo or in a cell line. Further, compounds according
to the present invention may be screened for activity against one
or more MEKs. Provided below are assays for activity against MEK1
and ERK1.
[0690] Purified MEK1, MEK2 and ERK1 may be obtained as follows.
[0691] For MEK1, DNA encoding residues 2-393 (del aa 32-51,
S218E/S222D) of the full-length sequence of the human enzyme may be
amplified by PCR and cloned into the BamHI/XbaI sites of pFastbac
(Invitrogen), which incorporates a 6-histidine tag at the
N-terminus. The deletion from residues 32-51, and the two
mutations, S218E and S222D, may be obtained by quick change PCR.
SEQ ID NO: 1 corresponds to residues 2-393, with deletion from
residues 32-51 and mutations S218E/S222D, and with the N-terminal
6-histidine tag. SEQ ID NO: 2 is the DNA sequence that was used to
encode SEQ ID NO: 1.
[0692] For MEK2, DNA encoding residues 1-400 (S222E/S226D) of the
full-length sequence of the human enzyme may be amplified by PCR
and cloned into pFastbac (Invitrogen), which incorporates a
6-histidine tag at the N-terminus. The two mutations, S222E and
S226D, may be obtained by quick change PCR. SEQ ID NO: 3
corresponds to residues 1-400 with mutations S222E/S226D, and with
the N-terminal 6-histidine tag and SEQ ID NO: 4 is the DNA sequence
that was used to encode SEQ ID NO: 3.
[0693] For ERK1, DNA encoding residues 1-379 of the full-length
sequence of the human enzyme may be amplified by PCR and cloned
into the SmalI/SalI sites of pGEX-6p-3 (GE Healthcare), which
incorporates a GST tag at the N-terminus. SEQ ID NO: 5 corresponds
to residues 1-379 with the N-terminal GST tag. SEQ ID NO: 6 is the
DNA sequence that was used to encode SEQ ID NO: 5.
[0694] Recombinant baculovirus incorporating the MEK1 and MEK2
constructs may be generated by transposition using the Bac-to-Bac
system (Invitrogen). High-titer viral stocks may be generated by
infection of Spodoptera frugiperda Sf9 cells; the expression of
recombinant protein may be carried out by infection of Spodoptera
frugiperda Sf9 (Invitrogen) in 5 L Wave Bioreactors (Wave
Biotech).
[0695] Recombinant protein may be isolated from cellular extracts
by passage over ProBond resin (Invitrogen). Partially purified
extracts of all MEK1 may then be further purified by high pressure
liquid chromatography over a SEC2000 gel filtration resin. The
purity of MEK1 and MEK2 proteins may be determined on denaturing
SDS-PAGE gel. Purified MEK1 and MEK2 may then be concentrated to a
final concentration of 3.4 mg/ml and 5.4 mg/ml, respectively. The
proteins may be either stored at -78.degree. C. in a buffer
containing 50 mM TRIS-HCl pH 7.6, 250 mM NaCl, 0.1 mM EDTA and
0.125 mM TCEP or at -20.degree. C. in the presence of glycerol
(final concentration of glycerol at 50%).
[0696] Recombinant protein incorporating the ERK1 constructs may be
generated by transformation of the expression vector into an E.
coli strain HD5a (Invitrogen). To express ERK1 protein, the
transformated E. coli strain may be cultured at 37.degree. C. C
until OD0.6, and then induced by adding IPTG to final concentration
of 0.5 mM, and continue to culture the cell overnight at 25.degree.
C.
[0697] Recombinant ERK1 protein may be isolated from cellular
extracts by passage over Glutathione (Amersham). Partially purified
extracts of ERK1 may then be further purified by high pressure
liquid chromatography over a BioSep SEC3000 gel filtration resin.
The purity of ERK1 protein may be determined on denaturing SDS-PAGE
gel. Purified ERK1 may then be concentrated to a final
concentration of 1.9 mg/ml. The proteins may be either stored at
-78.degree. C. in a buffer containing 25 mM TRIS-HCl pH 7.6, 150 mM
NaCl, 1 mM EDTA and 0.25 mM TCEP or at -20.degree. C. in the
presence of glycerol (final concentration of glycerol at 50%).
[0698] It should be noted that a variety of other expression
systems and hosts are also suitable for the expression of MEK1 and
ERK1, as would be readily appreciated by one of skill in the
art.
[0699] The inhibitory properties of compounds relative to MEK1 or
MEK2 may be determined using a black 384-well-plate format under
the following reaction conditions: 50 mM HEPES pH 7.3, 10 mM NaCl,
10 mM MgCl.sub.2, 0.01% Brij35, 1 nM MEK1 or 4 nM MEK2, 25 nM ERK1,
400 .mu.M ATP, 500 nM IPTTPITTYFFFK-5FAM-COOH (FI-Erktide), and 1%
DMSO. Reaction product is determined quantitatively by fluorescent
polarization using progressive IMAP beads from Molecular
Devices.
[0700] The assay reaction may be initiated as follows: 2 .mu.l of
the mixture of 1.5 .mu.M FI-Erktide and 75 nM ERK with 2 .mu.l of
inhibitor (2 fold serial dilutions for 11 data points for each
inhibitor) containing 3% DMSO were added to each well of the plate,
followed by the addition of 2 .mu.l of the mixture of 3 nM MEK1 or
12 nM MEK2 and 1200 .mu.M ATP to initiate the reaction (final
enzyme concentration was 1 nM for MEK1 or 4 nM for MEK2). The
reaction mixture may then be incubated at room temperature for 22
min, and quenched and developed by addition of 20 .mu.l of 1:200
dilution of progressive IMAP beads (Molecular Devices) in 80%
buffer A, 20% buffer B and 0.003% Tween 20. Fluorescence
polarization of the resulting reaction mixtures may be measured
after a 1 hour incubation at room temperature.
[0701] IC.sub.50 values may be calculated by non-linear curve
fitting of the compound concentrations and fluorescence
polarization signal to the standard IC.sub.50 equation. IC.sub.50
values for select compounds are given in Table 1.
