## Abstract

The present invention provides certain pyrazoline compounds useful as inhibitors of protein kinases. The invention also provides pharmaceutical compositions and methods of using the compositions in the treatment of various diseases.

## Background
The present invention relates to certain protein kinase inhibitors, particularly inhibitors of Raf-kinase. The invention also provides pharmaceutical compositions and methods of using the compositions in the treatment of various diseases.
Protein kinases constitute a large family of structurally related enzymes that effect the transfer of a phosphate group from a nucleoside triphosphate to a Ser, Thr or Tyr residue on a protein acceptor. A vast array of cellular functions, including DNA replication, cell cycle progression, energy metabolism, and cell growth and differentiation, are regulated by reversible protein phosphorylation events mediated by protein kinases. Additionally, protein kinase activity has been implicated in a number of disease states, including cancers. Of the >100 dominant oncogenes known to date, many encode receptor and cytoplasmic protein kinases known to be mutated and/or over expressed in human cancers (Blume-Jensen and Hunter, Nature, 411:355-365 (2001)). Accordingly, protein kinase targets have attracted substantial drug discovery efforts in recent years, with several protein kinase inhibitors achieving regulatory approval (reviewed in Fischer, Curr. Med. Chem., 11:1563 (2004); Dancey and Sausville, Nature Rev. Drug Disc., 2:296 (2003)).
Intracellular signaling pathways activated in response to growth factor/cytokine stimulation are known to control functions such as proliferation, differentiation and cell death (Chiloeches and Marais, In Targets for Cancer Therapy; Transcription Factors and Other Nuclear Proteins, 179-206 (La Thangue and Bandara, eds., Totowa, Humana Press 2002)). One example is the Ras-Raf-MEK-ERK pathway which is controlled by receptor tyrosine kinase activation. Activation of Ras proteins at the cell membrane leads to phosphorylation and recruitment of accessory factors and Raf which is then activated by phosphorylation. Activation of Raf leads to downstream activation of MEK and ERK. ERK has several cytoplasmic and nuclear substrates, including ELK and Ets-family transcription factor, which regulates genes involved in cell growth, survival and migration (Marais et al., J. Biol. Chem., 272:4378-4383 (1997); Peyssonnaux and Eychene, Biol. Cell, 93-53-62 (2001)). As a result, this pathway is an important mediator of tumor cell proliferation and angiogenesis. For instance, overexpression of constitutively active B-Raf can induce an oncogenic event in untransformed cells (Wellbrock et al., Cancer Res., 64:2338-2342 (2004)). Aberrant activation of the pathway, such as by activating Ras and/or Raf mutations, is known to be associated with a malignant phenotype in a variety of tumor types (Bos, Hematol. Pathol., 2:55-63 (1988); Downward, Nature Rev. Cancer, 3:11-22 (2003); Karasarides et al., Oncogene, 23:6292-6298 (2004); Tuveson, Cancer Cell, 4:95-98 (2003); Bos, Cancer Res, 49:4682-4689 (1989)). Activating mutations in B-Raf are found in 60-70% of melanomas. Melanoma cells that carry mutated B-Raf-V599E are transformed, and cell growth, ERK signaling and cell viability are dependent on mutant B-Raf function (Karasarides et al., Oncogene, 23:6292-6298 (2004)). Although this mutation historically has been referred to in the literature as V599E, the mutated valine actually is located at position 600 (Wellbrock et al., Cancer Res., 64:2338-2342 (2004)).
There are three Raf isoforms, A-Raf, B-Raf and C-Raf (Raf-1), all of which can act as downstream effectors of Ras. Although they show significant sequence similarities, they also exhibit distinct roles in development, in addition to significant biochemical and functional differences. In particular, the high basal kinase activity of B-Raf may explain why mutated forms of only this isoform have been found in human cancers. Nevertheless, the isoforms show redundant functions in facilitating oncogenic Ras-induced activation of the MEK-ERK signaling cascade (Wellbrock, Cancer Res, 64:2338-2342 (2004)). In addition to Raf signaling via the MEK-ERK pathway, there is some evidence that C-Raf (and possibly B-Raf and A-Raf) may signal via alternative pathways directly involved in cell survival by interaction with the BH3 family of anti-apoptotic proteins (Wellbrock et al., Nature Rev.: Mol. Cell. Biol., 5:875 (2004)).
Inhibitors of the Raf kinases may be expected to interrupt the Ras-Raf signaling cascade and thereby provide new methods for the treatment of proliferative disorders, such as cancer. There is thus a need for new inhibitors of Raf kinase activity.

Also provided is a method for the treatment or prophylaxis of cancer in a patient in need thereof, comprising administering to the patient at least one chemical entity described herein.
Chemical entities of the invention include those described generally above, and are further illustrated by the classes, subclasses, and species disclosed herein. Terms used herein shall be accorded the following defined meanings, unless otherwise indicated.
The terms “Raf” and “Raf kinase” are used interchangeably, and unless otherwise specified refer to any member of the Raf family of kinase enzymes, including without limitation, the isoforms A-Raf, B-Raf, and C-Raf. These enzymes, and the corresponding genes, also may be referred to in the literature by variants of these terms, e.g., RAF, raf; BRAF, B-raf, b-raf; CRAF, C-raf, c-raf, Raf-1 and C-Raf-1.
The term “aliphatic” or “aliphatic group”, as used herein, means a substituted or unsubstituted straight-chain, branched, or cyclic C1-12 hydrocarbon, which is completely saturated or which contains one or more units of unsaturation, but which is not aromatic. For example, suitable aliphatic groups include substituted or unsubstituted linear, branched or cyclic alkyl, alkenyl, or alkynyl groups and hybrids thereof, such as (cycloalkyl)alkyl, (cycloalkenyl)alkyl or (cycloalkyl)alkenyl. In various embodiments, the aliphatic group has 1 to 12, 1 to 8, 1 to 6, 1 to 4, or 1 to 3 carbons.
The terms “alkyl”, “alkenyl”, and “alkynyl”, used alone or as part of a larger moiety, refer to a straight or branched chain aliphatic group having from 1 to 12 carbon atoms. For purposes of the present invention, the term “alkyl” will be used when the carbon atom attaching the aliphatic group to the rest of the molecule is a saturated carbon atom. However, an alkyl group may include unsaturation at other carbon atoms. Thus, alkyl groups include, without limitation, methyl, ethyl, propyl, allyl, propargyl, butyl, pentyl, and hexyl.
For purposes of the present invention, the term “alkenyl” will be used when the carbon atom attaching the aliphatic group to the rest of the molecule forms part of a carbon-carbon double bond. Alkenyl groups include, without limitation, vinyl, 1-propenyl, 1-butenyl, 1-pentenyl, and 1-hexenyl.
For purposes of the present invention, the term “alkynyl” will be used when the carbon atom attaching the aliphatic group to the rest of the molecule forms part of a carbon-carbon triple bond. Alkynyl groups include, without limitation, ethynyl, 1-propynyl, 1-butynyl, 1-pentynyl, and 1-hexynyl.
The term “cycloaliphatic”, used alone or as part of a larger moiety, refers to a saturated or partially unsaturated cyclic aliphatic ring system having from 3 to about 14 members, wherein the aliphatic ring system is optionally substituted. In some embodiments, the cycloaliphatic is a monocyclic hydrocarbon having 3-8 or 3-6 ring carbon atoms. Nonlimiting examples include cyclopropyl, cyclobutyl, cyclopentyl, cyclopentenyl, cyclohexyl, cyclohexenyl, cycloheptyl, cycloheptenyl, cyclooctyl, cyclooctenyl, and cyclooctadienyl. In some embodiments, the cycloaliphatic is a bridged or fused bicyclic hydrocarbon having 6-12, 6-10, or 6-8 ring carbon atoms, wherein any individual ring in the bicyclic ring system has 3-8 members.
In some embodiments, two adjacent substituents on the cycloaliphatic ring, taken together with the intervening ring atoms, form an optionally substituted fused 5- to 6-membered aromatic or 3- to 8-membered non-aromatic ring having 0-3 ring heteroatoms selected from the group consisting of O, N, and S. Thus, the term “cycloaliphatic” includes aliphatic rings that are fused to one or more aryl, heteroaryl, or heterocyclyl rings. Nonlimiting examples include indanyl, 5,6,7,8-tetrahydroquinoxalinyl, decahydronaphthyl, or tetrahydronaphthyl, where the radical or point of attachment is on the aliphatic ring.
The terms “aryl” and “ar-”, used alone or as part of a larger moiety, e.g., “aralkyl”, “aralkoxy”, or “aryloxyalkyl”, refer to a C6 to C14 aromatic hydrocarbon, comprising one to three rings, each of which is optionally substituted. Preferably, the aryl group is a C6-10 aryl group. Aryl groups include, without limitation, phenyl, naphthyl, and anthracenyl. In some embodiments, two adjacent substituents on the aryl ring, taken together with the intervening ring atoms, form an optionally substituted fused 5- to 6-membered aromatic or 4- to 8-membered non-aromatic ring having 0-3 ring heteroatoms selected from the group consisting of O, N, and S. Thus, the term “aryl”, as used herein, includes groups in which an aryl ring is fused to one or more heteroaryl, cycloaliphatic, or heterocyclyl rings, where the radical or point of attachment is on the aromatic ring. Nonlimiting examples of such fused ring systems include indolyl, isoindolyl, benzothienyl, benzofuranyl, dibenzofuranyl, indazolyl, benzimidazolyl, benzthiazolyl, quinolyl, isoquinolyl, cinnolinyl, phthalazinyl, quinazolinyl, quinoxalinyl, carbazolyl, acridinyl, phenazinyl, phenothiazinyl, phenoxazinyl, tetrahydroquinolinyl, tetrahydroisoquinolinyl, fluorenyl, indanyl, phenanthridinyl, tetrahydronaphthyl, indolinyl, phenoxazinyl, benzodioxanyl, and benzodioxolyl. An aryl group may be mono-, bi-, tri-, or polycyclic, preferably mono-, bi-, or tricyclic, more preferably mono- or bicyclic. The term “aryl” may be used interchangeably with the terms “aryl group”, “aryl moiety”, and “aryl ring”.
Bivalent radicals formed from substituted benzene derivatives and having the free valences at ring atoms are named as substituted phenylene radicals. Bivalent radicals derived from univalent polycyclic hydrocarbon radicals whose names end in “-yl” by removal of one hydrogen atom from a ring carbon atom are named by adding “-ene” to the name of the corresponding univalent radical, e.g., a naphthyl group with two points of attachment is termed naphthylene.
An “aralkyl” or “arylalkyl” group comprises an aryl group covalently attached to an alkyl group, either of which independently is optionally substituted. Preferably, the aralkyl group is C6-10 aryl(C1-6)alkyl, C6-10 aryl(C1-4)alkyl, or C6-10 aryl(C1-3)alkyl, including, without limitation, benzyl, phenethyl, and naphthylmethyl.
The terms “heteroaryl” and “heteroar-”, used alone or as part of a larger moiety, e.g., heteroaralkyl, or “heteroaralkoxy”, refer to groups having 5 to 14 ring atoms, preferably 5, 6, 9, or 10 ring atoms; having 6, 10, or 14 .pi. electrons shared in a cyclic array; and having, in addition to carbon atoms, from one to four heteroatoms. The term “heteroatom” refers to nitrogen, oxygen, or sulfur, and includes any oxidized form of nitrogen or sulfur, and any quaternized form of a basic nitrogen. Thus, when used in reference to a ring atom of a heteroaryl, the term “nitrogen” includes an oxidized nitrogen (as in pyridine N-oxide). Certain nitrogen atoms of 5-membered heteroaryl groups also are substitutable, as further defined below. Heteroaryl groups include, without limitation, radicals derived from thiophene, furan, pyrrole, imidazole, pyrazole, triazole, tetrazole, oxazole, isoxazole, oxadiazole, thiazole, isothiazole, thiadiazole, pyridine, pyridazine, pyrimidine, pyrazine, indolizine, naphthyridine, pteridine, pyrrolopyridine, imidazopyridine, oxazolopyridine, thiazolopyridine, triazolopyridine, pyrrolopyrimidine, purine, and triazolopyrimidine. As used herein, the phrase “radical derived from” means a monovalent radical produced by removal of a hydrogen radical from the parent heteroaromatic ring system. The radical (i.e., the point of attachment of the heteroaryl to the rest of the molecule) may be created at any substitutable position on any ring of the parent heteroaryl ring system.
In some embodiments, two adjacent substituents on the heteroaryl, taken together with the intervening ring atoms, form an optionally substituted fused 5- to 6-membered aromatic or 4- to 8-membered non-aromatic ring having 0-3 ring heteroatoms selected from the group consisting of O, N, and S. Thus, the terms “heteroaryl” and “heteroar-”, as used herein, also include groups in which a heteroaromatic ring is fused to one or more aryl, cycloaliphatic, or heterocyclyl rings, where the radical or point of attachment is on the heteroaromatic ring. Nonlimiting examples include indolyl, isoindolyl, benzothienyl, benzofuranyl, dibenzofuranyl, indazolyl, benzimidazolyl, benzthiazolyl, benzoxazolyl, quinolyl, isoquinolyl, cinnolinyl, phthalazinyl, quinazolinyl, quinoxalinyl, 4H-quinolizinyl, carbazolyl, acridinyl, phenazinyl, phenothiazinyl, phenoxazinyl, tetrahydroquinolinyl, tetrahydroisoquinolinyl, and pyrido[2,3-b]-1,4-oxazin-3(4H)-one. A heteroaryl group may be mono-, bi-, tri-, or polycyclic, preferably mono-, bi-, or tricyclic, more preferably mono- or bicyclic. The term “heteroaryl” may be used interchangeably with the terms “heteroaryl ring”, or “heteroaryl group”, any of which terms include rings that are optionally substituted. The term “heteroaralkyl” refers to an alkyl group substituted by a heteroaryl, wherein the alkyl and heteroaryl portions independently are optionally substituted.
As used herein, the terms “aromatic ring” and “aromatic ring system” refer to an optionally substituted mono-, bi-, or tricyclic group having 0-6, preferably 0-4 ring heteroatoms, and having 6, 10, or 14 .pi. electrons shared in a cyclic array. Thus, the terms “aromatic ring” and “aromatic ring system” encompass both aryl and heteroaryl groups.
As used herein, the terms “heterocycle”, “heterocyclyl”, “heterocyclic radical”, and “heterocyclic ring” are used interchangeably and refer to a stable 3- to 7-membered monocyclic, or to a fused 7- to 10-membered or bridged 6- to 10-membered bicyclic heterocyclic moiety that is either saturated or partially unsaturated, and having, in addition to carbon atoms, one or more, preferably one to four, heteroatoms, as defined above. When used in reference to a ring atom of a heterocycle, the term “nitrogen” includes a substituted nitrogen. As an example, in a heterocyclyl ring having 1-3 heteroatoms selected from oxygen, sulfur or nitrogen, the nitrogen may be N (as in 3,4-dihydro-2H-pyrrolyl), NH (as in pyrrolidinyl), or +NR (as in N-substituted pyrrolidinyl). A heterocyclic ring can be attached to its pendant group at any heteroatom or carbon atom that results in a stable structure, and any of the ring atoms can be optionally substituted. For example, a heterocyclic ring having at least one nitrogen atom can be attached by that nitrogen atom. Examples of such saturated or partially unsaturated heterocyclic radicals include, without limitation, tetrahydrofuranyl, tetrahydrothienyl, pyrrolidinyl, pyrrolidonyl, piperidinyl, pyrrolinyl, tetrahydroquinolinyl, tetrahydroisoquinolinyl, decahydroquinolinyl, oxazolidinyl, piperazinyl, dioxanyl, dioxolanyl, diazepinyl, oxazepinyl, thiazepinyl, morpholinyl, and quinuclidinyl.
In some embodiments, two adjacent substituents on a heterocyclic ring, taken together with the intervening ring atoms, form an optionally substituted fused 5- to 6 membered aromatic or 3- to 8-membered non-aromatic ring having 0-3 ring heteroatoms selected from the group consisting of O, N, and S. Thus, the terms “heterocycle”, “heterocyclyl”, “heterocyclyl ring”, “heterocyclic group”, “heterocyclic moiety”, and “heterocyclic radical”, are used interchangeably herein, and include groups in which a heterocyclyl ring is fused to one or more aryl, heteroaryl, or cycloaliphatic rings, such as indolinyl, 3H-indolyl, chromanyl, phenanthridinyl, or tetrahydroquinolinyl, where the radical or point of attachment is on the heterocyclyl ring. A heterocyclyl group may be mono-, bi-, tri-, or polycyclic, preferably mono-, bi-, or tricyclic, more preferably mono- or bicyclic. The term “heterocyclylalkyl” refers to an alkyl group substituted by a heterocyclyl, wherein the alkyl and heterocyclyl portions independently are optionally substituted.
Bivalent radicals derived from univalent heteroaryl radicals whose names end in “-yl” by removal of one hydrogen atom from a ring atom are named by adding “-ene” to the name of the corresponding univalent radical, e.g., a pyridyl group with two points of attachment is a pyridylene.
As used herein, the term “partially unsaturated” refers to a ring moiety that includes at least one double or triple bond between ring atoms. The term “partially unsaturated” is intended to encompass rings having multiple sites of unsaturation, but is not intended to include aryl or heteroaryl moieties, as herein defined.
The terms “haloaliphatic”, “haloalkyl”, “haloalkenyl” and “haloalkoxy” refer to an aliphatic, alkyl, alkenyl or alkoxy group, as the case may be, which is substituted with one or more halogen atoms. As used herein, the term “halogen” or “halo” means F, Cl, Br, or I. The term “fluoroaliphatic” refers to a haloaliphatic wherein the halogen is fluoro, including perfluorinated aliphatic groups. Examples of fluoroaliphatic groups include, without limitation, fluoromethyl, difluoromethyl, trifluoromethyl, 2-fluoroethyl, 2,2,2-trifluoroethyl, 1,1,2-trifluoroethyl, 1,2,2-trifluoroethyl, and pentafluoroethyl.
The term “linker group” or “linker” means an organic moiety that connects two parts of a compound. Linkers typically comprise an atom such as oxygen or sulfur, a unit such as —NH—, —CH2—, —C(O)—, —C(O)NH—, or a chain of atoms, such as an alkylene chain. The molecular mass of a linker is typically in the range of about 14 to 200, preferably in the range of 14 to 96 with a length of up to about six atoms. In some embodiments, the linker is a C1-6 alkylene chain.
The term “alkylene” refers to a bivalent alkyl group. An “alkylene chain” is a polymethylene group, i.e., —(CH2)n—, wherein n is a positive integer, preferably from 1 to 6, from 1 to 4, from 1 to 3, from 1 to 2, or from 2 to 3. A substituted alkylene chain is a polymethylene group in which one or more methylene hydrogen atoms is replaced with a substituent. Suitable substituents include those described below for a substituted aliphatic group. An alkylene chain also may be substituted at one or more positions with an aliphatic group or a substituted aliphatic group.
An alkylene chain also can be optionally interrupted by a functional group. An alkylene chain is “interrupted” by a functional group when an internal methylene unit is replaced with the functional group. Examples of suitable “interrupting functional groups” include —C(R*)═C(R*)—, —C≡C, —, —S—, —S(O)—, —S(O)2—, —S(O)2N(R+)—, —N(R*)—, —N(R+)CO—, —N(R+)C(O)N(R+)—, —N(R+)C(═NR+)—N(R+)—, —N(R+)—C(═NR+)—, —N(R+)CO2—, —N(R+)SO2—, —N(R+)SO2N(R+)—, —OC(O)—, —OC(O)O—, —OC(O)N(R+)—, —C(O)—, —CO2—, —C(O)N(R+)—, —C(O)—C(O)—, —C(═NR+)—N(R+)—, —C(NR+)═N—, —C(═NR+)—O—, —C(OR*)═N—, —C(Ro)═N—O—, or —N(R+)—N(R+)—. Each R+, independently, is hydrogen or an optionally substituted aliphatic, aryl, heteroaryl, or heterocyclyl group, or two R+ on the same nitrogen atom, taken together with the nitrogen atom, form a 4-8 membered aromatic or non-aromatic ring having, in addition to the nitrogen atom, 0-2 ring heteroatoms selected from N, O, and S. Each R* independently is hydrogen or an optionally substituted aliphatic, aryl, heteroaryl, or heterocyclyl group.
Examples of C3-6 alkylene chains that have been “interrupted” with —O— include —CH2OCH2—, —CH2O—(CH2)2—, —CH2O(CH2)3—, —CH2O—(CH2)4—, —(CH2)2OCH2, —(CH2)2O(CH2)2—, —(CH2)2O(CH2)3—, —(CH2)3O(CH2)—, —(CH2)3O(CH2)2—, and —(CH2)4O(CH2)—. Other examples of alkylene chains that are “interrupted” with functional groups include —CH2ZCH2—, —CH2Z(CH2)2—, —CH2Z(CH2)3—, —CH2Z(CH2)4—, —(CH2)2ZCH2—, —(CH2)2Z(CH2)2—, —(CH2)2Z(CH2)3—, —(CH2)3Z(CH2)—, —(CH2)3Z(CH2)2—, and —(CH2)4Z(CH2)—, wherein Z is one of the “interrupting functional groups” listed above.
For purposes of clarity, all bivalent groups described herein, including, e.g., the alkylene chain linkers described above and the variables L1, L2, and X, are intended to be read from left to right, with a corresponding left-to-right reading of the formula or structure in which the variable appears.
One of ordinary skill in the art will recognize that when an alkylene chain having an interruption is attached to a functional group, certain combinations are not sufficiently stable for pharmaceutical use. Only stable or chemically feasible compounds are within the scope of the present invention. A stable or chemically feasible compound is one in which the chemical structure is not substantially altered when kept at a temperature from about −80° C. to about +40° C., preferably −20° C. to about +40° C. in the absence of moisture or other chemically reactive conditions, for at least a week, or a compound which maintains its integrity long enough to be useful for therapeutic or prophylactic administration to a patient.
The term “substituted”, as used herein, means that a hydrogen radical of the designated moiety is replaced with the radical of a specified substituent, provided that the substitution results in a stable or chemically feasible compound. The term “substitutable”, when used in reference to a designated atom, means that attached to the atom is a hydrogen radical, which can be replaced with the radical of a suitable substituent.
The phrase “one or more substituents”, as used herein, refers to a number of substituents that equals from one to the maximum number of substituents possible based on the number of available bonding sites, provided that the above conditions of stability and chemical feasibility are met. Unless otherwise indicated, an optionally substituted group may have a substituent at each substitutable position of the group, and the substituents may be either the same or different.
As used herein, the term “independently selected” means that the same or different values may be selected for multiple instances of a given variable in a single compound. By way of example, in a compound of formula (I), if R1 is substituted with two substituents, each substituent is selected from the group of defined values for that substituent, and the two values selected may be the same or different.

The compounds of the present invention can be prepared by methods known to one of ordinary skill in the art and/or by reference to the schemes shown below and the synthetic examples that follow. Exemplary synthetic routes are set forth in Schemes 1 and 2 below, and in the Examples.




Scheme 1 above shows a general route for preparing compounds of formula (I). Reaction of i and ii where R1 and R2 are appropriately substituted cycles, gives chalcone iii (a). Treatment with hydrazine monohydrate in EtOH gives pyrazoline iv (b). Compounds v are prepared by reacting iv with carboxylic acids to give amides (c), sulfonyl chlorides to give sulfonamides (d) and isocyanates to give substituted ureas (e).




Alternatively, compound v can be prepared by transition metal-mediated cross-coupling of compound vi with Cy2-M, where M is a boronic acid, zinc, or tin moiety. For example, as depicted in Scheme 2, compound v can be prepared by Suzuki coupling of compound vi with a boronic acid derivative of Cy2 in the presence of a palladium catalyst.
One of ordinary skill in the art will recognize that additional compounds of formula (I) may be prepared by methods analogous to those depicted above by changing the starting materials or reagents.
As discussed above, the present invention provides compounds that are inhibitors of Raf kinases. The compounds can be assayed in vitro or in vivo for their ability to bind to and/or inhibit a Raf kinase. In vitro assays include assays to determine inhibition of the ability of the kinase to phosphorylate a substrate protein or peptide. Alternate in vitro assays quantitate the ability of the compound to bind to the kinase. Inhibitor binding may be measured by radiolabelling the inhibitor prior to binding, isolating the inhibitor/kinase complex and determining the amount of radiolabel bound. Alternatively, inhibitor binding may be determined by running a competition experiment in which new inhibitors are incubated with the kinase bound to a known radioligand. The compounds also can be assayed for their ability to affect cellular or physiological functions mediated by protein kinase activity. Assays for each of these activities are described in the Examples and/or are known in the art.
In another aspect, therefore, the invention provides a method for inhibiting Raf kinase activity in a cell, comprising contacting a cell in which inhibition of a Raf kinase is desired with a compound of formula (I). In some embodiments, the compound of formula (I) interacts with and reduces the activity of more than one Raf kinase enzyme in the cell. By way of example, when assayed against B-Raf and C-Raf, some compounds of formula (I) show inhibition of both enzymes. In some embodiments, the compound of formula (I) is selective, i.e., the concentration of the compound that is required for inhibition of one Raf kinase enzymes is lower, preferably at least 2-fold, 5-fold, 10-fold, or 50-fold lower, than the concentration of the compound required for inhibition of another Raf kinase enzyme.
In some embodiments, the compound of formula (I) inhibits one or more Raf kinase enzymes at a concentration that is lower than the concentration of the compound required for inhibition of other, unrelated, kinase enzymes. In some other embodiments, in addition to inhibiting Raf kinase, the compound formula (I) also inhibits one or more other kinase enzymes, preferably other kinase enzymes involved in tumor cell proliferation.
The invention thus provides a method for inhibiting cell proliferation, comprising contacting a cell in which such inhibition is desired with a compound of formula (I). The phrase “inhibiting cell proliferation” is used to denote the ability of a compound of formula (I) to inhibit cell number or cell growth in contacted cells as compared to cells not contacted with the inhibitor. An assessment of cell proliferation can be made by counting cells using a cell counter or by an assay of cell viability, e.g., an MTT or WST assay. Where the cells are in a solid growth (e.g., a solid tumor or organ), such an assessment of cell proliferation can be made by measuring the growth, e.g., with calipers, and comparing the size of the growth of contacted cells with non-contacted cells.
Preferably, the growth of cells contacted with the inhibitor is retarded by at least about 50% as compared to growth of non-contacted cells. In various embodiments, cell proliferation of contacted cells is inhibited by at least about 75%, at least about 90%, or at least about 95% as compared to non-contacted cells. In some embodiments, the phrase “inhibiting cell proliferation” includes a reduction in the number of contacted cells, as compare to non-contacted cells. Thus, a kinase inhibitor that inhibits cell proliferation in a contacted cell may induce the contacted cell to undergo growth retardation, to undergo growth arrest, to undergo programmed cell death (i.e., apoptosis), or to undergo necrotic cell death.
In another aspect, the invention provides a pharmaceutical composition comprising a compound of formula (I) as defined above, or a pharmaceutically acceptable salt thereof, and a pharmaceutically acceptable carrier.
If pharmaceutically acceptable salts of the compounds of the invention are utilized in these compositions, the salts preferably are derived from inorganic or organic acids and bases. For reviews of suitable salts, see, e.g., Berge et al, J. Pharm. Sci. 66:1-19 (1977) and Remington: The Science and Practice of Pharmacy, 20th Ed., ed. A. Gennaro, Lippincott Williams & Wilkins, 2000.
Nonlimiting examples of suitable acid addition salts include the following: acetate, adipate, alginate, aspartate, benzoate, benzene sulfonate, bisulfate, butyrate, citrate, camphorate, camphor sulfonate, cyclopentanepropionate, digluconate, dodecylsulfate, ethanesulfonate, formate, fumarate, lucoheptanoate, glycerophosphate, hemisulfate, heptanoate, hexanoate, hydrochloride, hydrobromide, hydroiodide, 2-hydroxyethanesulfonate, lactate, maleate, methanesulfonate, 2-naphthalenesulfonate, nicotinate, oxalate, pamoate, pectinate, persulfate, 3-phenyl-propionate, picrate, pivalate, propionate, succinate, tartrate, thiocyanate, tosylate and undecanoate.
Suitable base addition salts include, without limitation, ammonium salts, alkali metal salts, such as sodium and potassium salts, alkaline earth metal salts, such as calcium and magnesium salts, salts with organic bases, such as dicyclohexylamine salts, N-methyl-D-glucamine, and salts with amino acids such as arginine, lysine, and so forth.
Also, basic nitrogen-containing groups may be quaternized with such agents as lower alkyl halides, such as methyl, ethyl, propyl, and butyl chloride, bromides and iodides; dialkyl sulfates, such as dimethyl, diethyl, dibutyl and diamyl sulfates, long chain halides such as decyl, lauryl, myristyl and stearyl chlorides, bromides and iodides, aralkyl halides, such as benzyl and phenethyl bromides and others. Water or oil-soluble or dispersible products are thereby obtained.
The term “pharmaceutically acceptable carrier” is used herein to refer to a material that is compatible with a recipient subject, preferably a mammal, more preferably a human, and is suitable for delivering an active agent to the target site without terminating the activity of the agent. The toxicity or adverse effects, if any, associated with the carrier preferably are commensurate with a reasonable risk/benefit ratio for the intended use of the active agent.
The pharmaceutical compositions of the invention can be manufactured by methods well known in the art such as conventional granulating, mixing, dissolving, encapsulating, lyophilizing, or emulsifying processes, among others. Compositions may be produced in various forms, including granules, precipitates, or particulates, powders, including freeze dried, rotary dried or spray dried powders, amorphous powders, tablets, capsules, syrup, suppositories, injections, emulsions, elixirs, suspensions or solutions. Formulations may optionally contain stabilizers, pH modifiers, surfactants, bioavailability modifiers and combinations of these.
Pharmaceutical formulations may be prepared as liquid suspensions or solutions using a liquid, such as, but not limited to, an oil, water, an alcohol, and combinations of these. Pharmaceutically suitable surfactants, suspending agents, or emulsifying agents, may be added for oral or parenteral administration. Suspensions may include oils, such as but not limited to, peanut oil, sesame oil, cottonseed oil, corn oil and olive oil. Suspension preparation may also contain esters of fatty acids such as ethyl oleate, isopropyl myristate, fatty acid glycerides and acetylated fatty acid glycerides. Suspension formulations may include alcohols, such as, but not limited to, ethanol, isopropyl alcohol, hexadecyl alcohol, glycerol and propylene glycol. Ethers, such as but not limited to, poly(ethyleneglycol), petroleum hydrocarbons such as mineral oil and petrolatum; and water may also be used in suspension formulations.
Pharmaceutically acceptable carriers that may be used in these compositions include, but are not limited to, ion exchangers, alumina, aluminum stearate, lecithin, serum proteins, such as human serum albumin, buffer substances such as phosphates, glycine, sorbic acid, potassium sorbate, partial glyceride mixtures of saturated vegetable fatty acids, water, salts or electrolytes, such as protamine sulfate, disodium hydrogen phosphate, potassium hydrogen phosphate, sodium chloride, zinc salts, colloidal silica, magnesium trisilicate, polyvinyl pyrrolidone, cellulose-based substances, polyethylene glycol, sodium carboxymethylcellulose, polyacrylates, waxes, polyethylene-polyoxypropylene-block polymers, polyethylene glycol and wool fat.
According to a preferred embodiment, the compositions of this invention are formulated for pharmaceutical administration to a mammal, preferably a human being. Such pharmaceutical compositions of the present invention may be administered orally, parenterally, by inhalation spray, topically, rectally, nasally, buccally, vaginally or via an implanted reservoir. The term “parenteral” as used herein includes subcutaneous, intravenous, intramuscular, intra-articular, intra-synovial, intrasternal, intrathecal, intrahepatic, intralesional and intracranial injection or infusion techniques. Preferably, the compositions are administered orally, intravenously, or subcutaneously. The formulations of the invention may be designed to be short-acting, fast-releasing, or long-acting. Still further, compounds can be administered in a local rather than systemic means, such as administration (e.g., by injection) at a tumor site.
Sterile injectable forms of the compositions of this invention may be aqueous or oleaginous suspension. These suspensions may be formulated according to techniques known in the art using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation may also be a sterile injectable solution or suspension in a non-toxic parenterally 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, Ringer's solution and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose, any bland fixed oil may be employed including synthetic mono- or di-glycerides. Fatty acids, such as oleic acid and its glyceride derivatives are useful in the preparation of injectables, as are natural pharmaceutically-acceptable oils, such as olive oil or castor oil, especially in their polyoxyethylated versions. These oil solutions or suspensions may also contain a long-chain alcohol diluent or dispersant, such as carboxymethyl cellulose or similar dispersing agents which are commonly used in the formulation of pharmaceutically acceptable dosage forms including emulsions and suspensions. Other commonly used surfactants, such as Tweens, Spans and other emulsifying agents or bioavailability enhancers which are commonly used in the manufacture of pharmaceutically acceptable solid, liquid, or other dosage forms may also be used for the purposes of formulation. Compounds may be formulated for parenteral administration by injection such as by bolus injection or continuous infusion. A unit dosage form for injection may be in ampoules or in multi-dose containers.
The pharmaceutical compositions of this invention may be orally administered in any orally acceptable dosage form including, but not limited to, capsules, tablets, aqueous suspensions or solutions. In the case of tablets for oral use, carriers that are commonly used include lactose and corn starch. Lubricating agents, such as magnesium stearate, are also typically added. For oral administration in a capsule form, useful diluents include lactose and dried cornstarch. When aqueous suspensions are required for oral use, the active ingredient is combined with emulsifying and suspending agents. If desired, certain sweetening, flavoring or coloring agents may also be added.
Alternatively, the pharmaceutical compositions of this invention may be administered in the form of suppositories for rectal administration. These may be prepared by mixing the agent with a suitable non-irritating excipient which is solid at room temperature but liquid at rectal temperature and therefore will melt in the rectum to release the drug. Such materials include cocoa butter, beeswax and polyethylene glycols.
The pharmaceutical compositions of this invention may also be administered topically, especially when the target of treatment includes areas or organs readily accessible by topical application, including diseases of the eye, the skin, or the lower intestinal tract. Suitable topical formulations are readily prepared for each of these areas or organs.
Topical application for the lower intestinal tract may be effected in a rectal suppository formulation (see above) or in a suitable enema formulation. Topically-transdermal patches may also be used. For topical applications, the pharmaceutical compositions may be formulated in a suitable ointment containing the active component suspended or dissolved in one or more carriers. Carriers for topical administration of the compounds of this invention include, but are not limited to, mineral oil, liquid petrolatum, white petrolatum, propylene glycol, polyoxyethylene, polyoxypropylene compound, emulsifying wax and water. Alternatively, the pharmaceutical compositions may be formulated in a suitable lotion or cream containing the active components suspended or dissolved in one or more pharmaceutically acceptable carriers. Suitable carriers include, but are not limited to, mineral oil, sorbitan monostearate, polysorbate 60, cetyl esters wax, cetearyl alcohol, 2-octyldodecanol, benzyl alcohol and water.
For ophthalmic use, the pharmaceutical compositions may be formulated as micronized suspensions in isotonic, pH adjusted sterile saline, or, preferably, as solutions in isotonic, pH adjusted sterile saline, either with our without a preservative such as benzylalkonium chloride. Alternatively, for ophthalmic uses, the pharmaceutical compositions may be formulated in an ointment such as petrolatum.
The pharmaceutical compositions of this invention may also be administered by nasal aerosol or inhalation. Such compositions are prepared according to techniques well known in the art of pharmaceutical formulation and may be prepared as solutions in saline, employing benzyl alcohol or other suitable preservatives, absorption promoters to enhance bioavailability, fluorocarbons, and/or other conventional solubilizing or dispersing agents.
The pharmaceutical compositions of the invention preferably are formulated for administration to a patient having, or at risk of developing or experiencing a recurrence of, a Raf kinase-mediated disorder. The term “patient”, as used herein, means an animal, preferably a mammal, more preferably a human. Preferred pharmaceutical compositions of the invention are those formulated for oral, intravenous, or subcutaneous administration. However, any of the above dosage forms containing a therapeutically effective amount of a compound of the invention are well within the bounds of routine experimentation and therefore, well within the scope of the instant invention. In some embodiments, the pharmaceutical composition of the invention may further comprise another therapeutic agent. In some embodiments, such other therapeutic agent is one that is normally administered to patients with the disease or condition being treated.
By “therapeutically effective amount” is meant an amount sufficient to cause a detectable decrease in protein kinase activity or the severity of a Raf kinase-mediated disorder. The amount of Raf kinase inhibitor needed will depend on the effectiveness of the inhibitor for the given cell type and the length of time required to treat the disorder. It should also be understood that a specific dosage and treatment regimen for any particular patient will depend upon a variety of factors, including the activity of the specific compound employed, the age, body weight, general health, sex, and diet of the patient, time of administration, rate of excretion, drug combinations, the judgment of the treating physician, and the severity of the particular disease being treated. The amount of additional therapeutic agent present in a composition of this invention typically will be no more than the amount that would normally be administered in a composition comprising that therapeutic agent as the only active agent. Preferably, the amount of additional therapeutic agent will range from about 50% to about 100% of the amount normally present in a composition comprising that agent as the only therapeutically active agent.
In another aspect, the invention provides a method for treating a patient having, or at risk of developing or experiencing a recurrence of, a Raf kinase-mediated disorder. As used herein, the term “Raf kinase-mediated disorder” includes any disorder, disease or condition which is caused or characterized by an increase in Raf kinase expression or activity, or which requires Raf kinase activity. The term “Raf kinase-mediated disorder” also includes any disorder, disease or condition in which inhibition of Raf kinase activity is beneficial.
The Raf kinase inhibitors of the invention can be used to achieve a beneficial therapeutic or prophylactic effect, for example, in subjects with a proliferative disorder. Non-limiting examples of proliferative disorders include chronic inflammatory proliferative disorders, e.g., psoriasis and rheumatoid arthritis; proliferative ocular disorders, e.g., diabetic retinopathy; benign proliferative disorders, e.g., hemangiomas; and cancer. As used herein, the term “cancer” refers to a cellular disorder characterized by uncontrolled or disregulated cell proliferation, decreased cellular differentiation, inappropriate ability to invade surrounding tissue, and/or ability to establish new growth at ectopic sites. The term “cancer” includes, but is not limited to, solid tumors and bloodborne tumors. The term “cancer” encompasses diseases of skin, tissues, organs, bone, cartilage, blood, and vessels. The term “cancer” further encompasses primary and metastatic cancers.
Non-limiting examples of solid tumors that can be treated with the disclosed Raf kinase inhibitors include pancreatic cancer; bladder cancer; colorectal cancer; breast cancer, including metastatic breast cancer; prostate cancer, including androgen-dependent and androgen-independent prostate cancer; renal cancer, including, e.g., metastatic renal cell carcinoma; hepatocellular cancer; lung cancer, including, e.g., non-small cell lung cancer (NSCLC), bronchioloalveolar carcinoma (BAC), and adenocarcinoma of the lung; ovarian cancer, including, e.g., progressive epithelial or primary peritoneal cancer; cervical cancer; gastric cancer; esophageal cancer; head and neck cancer, including, e.g., squamous cell carcinoma of the head and neck; skin cancer, including e.g., malignant melanoma; neuroendocrine cancer, including metastatic neuroendocrine tumors; brain tumors, including, e.g., glioma, anaplastic oligodendroglioma, adult glioblastoma multiforme, and adult anaplastic astrocytoma; bone cancer; soft tissue sarcoma; and thyroid carcinoma.
Non-limiting examples of hematologic malignancies that can be treated with the disclosed Raf kinase inhibitors include acute myeloid leukemia (AML); chronic myelogenous leukemia (CML), including accelerated CML and CML blast phase (CML-BP); acute lymphoblastic leukemia (ALL); chronic lymphocytic leukemia (CLL); Hodgkin's disease (HD); non-Hodgkin's lymphoma (NHL), including follicular lymphoma and mantle cell lymphoma; B-cell lymphoma; T-cell lymphoma; multiple myeloma (MM); Waldenstrom's macroglobulinemia; myelodysplastic syndromes (MDS), including refractory anemia (RA), refractory anemia with ringed siderblasts (RARS), (refractory anemia with excess blasts (RAEB), and RAEB in transformation (RAEB-T); and myeloproliferative syndromes.
The compounds of formula (I) are particularly useful in the treatment of cancers or cell types characterized by aberrant activation of the Ras-Raf-MEK-ERK pathway, including, without limitation, those characterized by an activating Ras and/or Raf mutation. In some embodiments, the compound or composition of the invention is used to treat a patient having or at risk of developing or experiencing a recurrence in a cancer selected from the group consisting of melanoma, colon, lung, breast, ovarian, sarcoma and thyroid cancer. In certain embodiments, the cancer is a melanoma.
In some embodiments, the Raf kinase inhibitor of the invention is administered in conjunction with another therapeutic agent. In some embodiments, the other therapeutic agent is one that is normally administered to patients with the disease or condition being treated. The Raf kinase inhibitor of the invention may be administered with the other therapeutic agent in a single dosage form or as a separate dosage form. When administered as a separate dosage form, the other therapeutic agent may be administered prior to, at the same time as, or following administration of the protein kinase inhibitor of the invention.
In some embodiments, a Raf kinase inhibitor of formula (I) is administered in conjunction with an anticancer agent. As used herein, the term “anticancer agent” refers to any agent that is administered to a subject with cancer for purposes of treating the cancer. Nonlimiting examples anticancer agents include: radiotherapy; immunotherapy; DNA damaging chemotherapeutic agents; and chemotherapeutic agents that disrupt cell replication.
Non-limiting examples of DNA damaging chemotherapeutic agents include topoisomerase I inhibitors (e.g., irinotecan, topotecan, camptothecin and analogs or metabolites thereof, and doxorubicin); topoisomerase II inhibitors (e.g., etoposide, teniposide, and daunorubicin); alkylating agents (e.g., melphalan, chlorambucil, busulfan, thiotepa, ifosfamide, carmustine, lomustine, semustine, streptozocin, decarbazine, methotrexate, mitomycin C, and cyclophosphamide); DNA intercalators (e.g., cisplatin, oxaliplatin, and carboplatin); DNA intercalators and free radical generators such as bleomycin; and nucleoside mimetics (e.g., 5-fluorouracil, capecitibine, gemcitabine, fludarabine, cytarabine, mercaptopurine, thioguanine, pentostatin, and hydroxyurea).
Chemotherapeutic agents that disrupt cell replication include: paclitaxel, docetaxel, and related analogs; vincristine, vinblastin, and related analogs; thalidomide and related analogs (e.g., CC-5013 and CC-4047); protein tyrosine kinase inhibitors (e.g., imatinib mesylate and gefitinib); proteasome inhibitors (e.g., bortezomib); NF-.kappa.B inhibitors, including inhibitors of I.kappa.B kinase; antibodies which bind to proteins overexpressed in cancers and thereby downregulate cell replication (e.g., trastuzumab, rituximab, cetuximab, and bevacizumab); and other inhibitors of proteins or enzymes known to be upregulated, over-expressed or activated in cancers, the inhibition of which downregulates cell replication.

Raf Kinase Cellular Assays
Phospho-ERK ELISA Assay
Inhibition of Raf kinase activity in whole cell systems can be assessed by determining the decrease in phosphorylation of Raf kinase substrates. Any known Raf kinase substrate can be used to measure inhibition of Raf kinase activity in a whole cell system.
In a specific example, A375 cells were seeded in a 96-well cell culture plate (12×103 cells/100 μL/well) and incubated overnight at 37° C. Medium was removed, and cells were incubated with Raf kinase inhibitors for 3 hours at 37° C. Medium was not removed, and cells were fixed with 4% paraformaldehyde for 15 minutes at room temperature.
Methanol was added for 20 min. Cells were removed and blocked with 10% sheep serum and 1% BSA in PBS overnight at 4° C. Cells were incubated with anti-p44/42MAPK antibody (1:100, Cell Signaling Technologies, #9101L) (20 μL/well) overnight at 4° C. After washing with PBS three times, cells were stained with anti-rabbit horseradish peroxidase-linked antibody from donkey (1:100, Amersham Bioscience #NA934V) for 1 hour at room temperature. Cells were washed three times with 0.5% Tween-20 in PBS and twice with PBS. 3,3′,5,5′-Tetramethylbenzidine (TMB) liquid substrate system (Sigma, #T8665) (50 μL/well) was added, and cells were incubated for 30-45 minutes at room temperature. Optical density was read at 650 nm. Cells were then washed 3-5 times with PBS to remove color solution. Results were normalized for the protein content in each well using a BCA protein assay kit (Pierce). Selected compounds in Table 1 were tested in this assay.

In Vivo Assays
In Vivo Tumor Efficacy Model
Raf kinase inhibitors are tested for their ability to inhibit tumor growth in standard xenograft tumor models.
For example, HCT-116 cells (1×106) in 100 μL of phosphate buffered saline are aseptically injected into the subcutaneous space in the right dorsal flank of female CD-1 nude mice (age 5-8 weeks, Charles River) using a 23-ga needle. Beginning at day 7 after inoculation, tumors are measured twice weekly using a vernier caliper. Tumor volumes are calculated using standard procedures (0.5×length×width2). When the tumors reach a volume of approximately 200 mm3, mice are injected i.v. in the tail vein with test compound (100 μL) at various doses and schedules. All control groups receive vehicle alone. Tumor size and body weight are measured twice a week, and the study is terminated when the control tumors reach approximately 2000 mm. Analogous procedures are followed for melanoma (A375 or A2058 cells), colon (HT-29 or HCT-116 cells), and lung (H460 cells) tumor models.
