Cross-Reference to Related Application

[0001] This application claims the benefit of copending U.S. Provisional Application Serial No. 60/583,009, filed June 24, 2004.

Field of the Invention

[0002] The invention relates to α,β-unsaturated sulfones, sulfoxides, sulfonimides, sulfinimides, acylsulfonamides and acylsulfinamides, and to pharmaceutical compositions containing such compounds. The invention further relates to compounds for use in methods of treatment comprising administration of such compounds.

Background of the Invention

A. Proliferative Disorders

[0003] Extracellular signals received at transmembrane receptors are relayed into the cells by signal transduction pathways (Pelech et al., Science 257:1335 (1992)) which have been implicated in induction of cell proliferation, differentiation or apoptosis (Davis et al., J. Biol. Chem. 268:14553 (1993)). One such signal transduction pathway is the mitogen activated protein kinase (MAPK) cascade. See, Nishida et al., Trends Biochem. Sci. 18:128 (1993) and Blumer et al., Trends Biochem. Sci. 19:236 (1994). Much of the MAPK pathway is conserved over different species. The most thoroughly studied of the MAPKs are extra cellular signal regulated kinases (ERKs) (Posada et al., Science 255:212 (1992); Biggs III et al., PNAS USA 89:6295 (1992); and Garner et al., Genes Dev. 6:1280 (1992)) and c-Jun NH₂ terminal kinases (JNKs) (Hibi et al., Genes Dev. 7:2135 (1993)). JNKs are members of a class of stress activated protein kinases (SAPK) and are shown to be activated by treatment of cells with UV radiation, pro-inflammatory cytokines and environmental stress (Derijard et al., Cell 1025 (1994)). Activation of ERK has been shown to involve kinase mediated phosphorylation of threonine and tyrosine residues, which signals cell proliferation. In contrast, activation of JNKs leads to cell growth inhibition and apoptosis.

[0004] Protein tyrosine kinases are enzymes which catalyze a well defined chemical reaction: the phosphorylation of a tyrosine residue (Hunter et al., Ann. Rev. Biochem. 54:897 (1985)). Receptor tyrosine kinases in particular are attractive targets for drug design since blockers for the substrate domain of these kinases is likely to yield an effective and selective antiproliferative agent. The potential use of protein tyrosine kinase blockers as antiproliferative agents was recognized as early as 1981, when quercetin was suggested as a PTK blocker (Graziani et al., Eur. J. Biochem. 135:583-589 (1983)).

[0005] The best understood MAPK pathway involves extracellular signal-regulated kinases which constitute the Ras/Raf/MEK/ERK kinase cascade (Boudewijn et al., Trends Biochem. Sci. 20, 18 (1995)). Once this pathway is activated by different stimuli, MAPK phosphorylates a variety of proteins including several transcription factors which translocate into the nucleus and activate gene transcription. Negative regulation of this pathway could arrest the cascade of these events.

B. Angiogenesis Inhibition

[0006] Angiogenesis, or development of new blood vessels, is implicated in a host of diseases including tumorigenesis, metastasis and tumor growth, retinopathies, neovascular ocular disorders, and postangioplasty or postatherectomy restenosis. See, Bicknell et al. (1996) Curr. Opin. Oncol. 8: 60-65; Gariano et al. (1996) Survey Ophthalmol. 40: 481-490; and Wilcox, J. N. (1993) Am. J. Cardiol. 72: 88E-95E).

[0007] Recent research has indicated that differences in the production of vascular endothelial growth factor (VEGF) and sFIt-1 by smooth muscle cells and human umbilical endothelial cells (HUVECs) are consistent with the role of these cells in angiogenesis. See, Belgore et al., Eur. J. Clin. Invest. 2003, 33(10), page 833-39. Studies have indicated a therapeutic potential of placental growth factor (PIGF) and its receptor FLT1 in angiogenesis. An antibody against FLT1 has been shown to suppress neovascularization in tumors and ischemic retina, and angiogenesis and inflammatory joint destruction in autoimmune arthritis. See, Luttun et al., Nat Med., 2002, 8(8) page 831-40.

[0008] Expression and secretion of angiogenic factors by tumors has been investigated. It has been suggested that because tumors express multiple angiogenic factors, broad spectrum antagonists of angiogenesis can provide effective means of tumor stabilization. Anti-angiogenic approaches to tumor therapy have been defined to involve interference with growth, migration and differentiation of blood vessels associated with tumor growth. Anti-angiogenic agents have been categorized to include protease inhibitors, modulators of cytokines, heparin-like molecules, and antagonists of vascular growth factors. Growth factor antagonists have been categorized to include heparin-like molecules, angiogenin antagonists, antisense fibroblast growth factor, DS 4152, suramin analogs, and protein-bound saccharide-K (Bicknell et al., Id).

C. Biological Activity of Curcumin

[0009] Curcumin is a compound that is isolated from the commonly used spice turmeric. The structure of curcumin is shown in Scheme 1.

Curcumin has been shown to inhibit the progression of chemically induced colon and skin cancers in animal models. In HT29 cells curcumin-induced modulation of genes involved in transition through the G2/M phase has been observed to correspond to a cell cycle arrest in the G2/M phase. See, van Erk et al., J. of Carcinogenesis 2004, 3:8. Curcumin has also been observed to downregulate expression of some cytochrome P450 genes and to affect expression of metallothionein genes, tubulin genes, p53 and other genes involved in colon carcinogenesis. Id.

[0010] The antiproliferative effects of curcumin are believed to be related to inhibition of aminopeptidase N (APN), an enzyme that is linked to invasiveness and angiogenesis in tumors. See, Kwon et al., Chem. Biol., 10, 695 (2003). Curcumin has also been shown to have direct antiangiogenic activity in vitro and in vivo. See, Arbiser et al., Mol Med., 1998,4(6): page 376-83.

[0011] Curcumin has also been shown to be effective in the dinitrobenzene sulfuric acid (DNB) induced murine colitis model, which is an experimental model of IBD. See, Salh et al., Am. J. Phys. Gastrointestinal and Liver Physiology, 2003 285(1), page 235-43. In the DNB-induced murine colitis model, curcumin was observed to attenuate macroscopic damage, to improve intestinal cell function, and to inhibit the nuclear transcription factor NF-kB activation in the colon.

[0012] Curcumin is also effective in biological assays that are predictive of activity in age-related neurodegenerative diseases such as Alzheimer's Disease (AD) and presenile dementia. Curcumin has been shown to reduce the oxidative damage (isoprostane levels) and synaptophysin loss induced by intracerebroventricular infusion of beta amyloid (Abeta) peptides. See, Chu et al., Neurobiol. Aging, 2001, 22(6): page 993-1005.

[0013] Cancer and other proliferative disorders remain a major unmet medical need. Cancer treatments often comprise surgery, chemotherapeutic treatments, radiation treatment or combinations thereof. Chemotherapeutic treatments for most cancers only delay disease progression rather than providing a cure. Cancers often become refractory to chemotherapy via development of multidrug resistance. Particular cancers are inherently resistant to some classes of chemotherapeutic agents. See DeVita et al, Principles of Cancer Management: Chemotherapy. In: Cancer. Principles and Practice of Oncology, 5th edition, Lippincott-Raven, Philadelphia, New York (1977), pp. 333-347. WO01/401 88 and WO01/78733 deal with Curcumin analogues for the treatment of cancer.

[0014] Progress continues in treatment of proliferative disorders such as cancer, and in the treatment of angiogenesis-mediated disorders. However, there remains a need to develop new therapeutic agents.

Detailed Description of the Invention

I. Treatment of Proliferative Disorders

[0122] According to the present invention, certain α,β-unsaturated sulfones, sulfoxides, sulfonimides, sulfinimides, acylsulfonamides and acylsulfinamides selectively kill various tumor cell types without killing normal cells. Without wishing to be bound by any theory, it is believed that the compounds affect the mitogen activated protein kinase (MAPK) signal transduction pathway, thereby affecting tumor cell growth and viability. This cell growth inhibition is believed to be associated with regulation of extracellular signal regulated kinases (ERKs) and c-Jun NH₂ terminal kinases (JNK) types of MAPK. The compounds according to the present invention are believed to activate the JNK pathway, either by interacting with JNK1 or by interacting with an upstream kinase that is a part of the JNK pathway.

[0123] The compounds according to the invention may be administered to individuals (mammals, including animals and humans) afflicted with a proliferative disorder such as cancer.

[0124] The compounds according to the invention have been shown to inhibit the proliferation of tumor cells by inducing cell death. The cell-killing activity of the compounds according to the invention is selective for tumor cells over normal cells.

[0127] Cancers may be solid tumors that may or may not be metastatic. Cancers may also occur, as in leukemia, as a diffuse tissue. Thus, the term "tumor cell" as provided herein, includes a cell afflicted by any one of the above identified disorders.

B. Treatment of Non-Cancer Proliferative Disorders

[0128] The compounds are also believed useful in the treatment of non-cancer proliferative disorders, that is, proliferative disorders which are characterized by benign indications. Such disorders may also be known as "cytoproliferative" or "hyperproliferative" in that cells are made by the body at an atypically elevated rate. Non-cancer proliferative disorders believed treatable by compounds according to the invention include, for example: hemangiomatosis in newborn, secondary progressive multiple sclerosis, atherosclerosis, chronic progressive myelodegenerative disease, neurofibromatosis, ganglioneuromatosis, keloid formation, Paget's Disease of the bone, fibrocystic disease of the breast, uterine fibroids, Peyronie's disease, Dupuytren's disease restenosis, benign proliferative breast disease, benign prostatic hyperplasia, X-linked lymphoproliferative disorder (Duncan disease), post-transplantation lymphoproliferative disorder (PTLD), macular degeneration, and retinopathies, such as diabetic retinopathies and proliferative vitreoretinopathy (PVR)

[0129] Other non-cancer proliferative disorders believed treatable by compounds according to the invention include the presence of pre-cancerous lymphoproliferative cells associated with an elevated risk of progression to a cancerous disorder. Many non-cancerous lymphoproliferative disorders are associated with latent viral infections such as Epstein-Barr virus (EBV) and Hepatitis C. These disorders often begin as a benign pathology and progress into lymphoid neoplasia as a function of time.

[0130] Treatment of tumor cells with the compounds according to the invention is believed to lead to inhibition of cell proliferation and induction of apoptotic cell death.

C. Treatment of Angiogenesis-mediated Disorders

[0131] The compounds of the invention are also believed to be useful in the treatment of angiogenesis-mediated disorders. Without wishing to be bound by any theory, it is believed that the compounds inhibit the action of vascular endothelial growth factor (VEGF), thereby inhibiting angiogenesis. Also without wishing to be bound by any theory, it is believed that the compounds inhibit the action of FMS-like tyrosine kinase (vascular endothelial growth factor/vascular permeability factor receptor) (FLT-1), thereby inhibiting angiogenesis.

[0132] Vascular endothelial growth factor (VEGF) is a dimeric heparin-binding glycoprotein that is a potent endothelial cell-specific mitogen with increased expression during adult cutaneous wound healing. VEGF activity is mediated by two receptors, VEGFR-1 (FLT-1) and VEGFR-2 (Flk-1/KDR), which are expressed primarily in vascular endothelial cells. See, Colwell et al., Plast. Reconstr. Surg.; 2005; 115(1); pages 204-12, the entire disclosure of which is incorporated herein by reference. FLT-1 expression has been shown to be significantly increased in heart cells and skeletal myoblasts wherein angiogenesis has been enhanced by and to increase eightfold by transplantation of vascular endothelial growth factor transfected cells. This observation suggests that FLT-1 upregulation may mediate the angiogenic effect of the cell transplantation. See, Yao et al., Ann. Thorac. Surg. 2005; 79(6); pages 2056-63, the entire disclosure of which is incorporated herein by reference. In vivo, delivery of naked plasmids expressing FLT-1 intraceptors inhibits injury-induced upregulation of VEGF, leukocyte infiltration, and corneal neovascularization. See, Singh et al., Invest. Ophthalmol. Vis. Sci. 2005; 46(5); pages 1647-52, the entire disclosure of which is incorporated herein by reference.

[0133] Thus compounds for use in a method for treating, inhibiting or delaying the onset of an angiogenesis-mediated disorder in a subject is provided comprising administering to a subject in need of such treatment an effective amount of a compound according to the present invention. Angiogenesis-mediated disorders which may be treatable with cyclooxygenase inhibitors are discussed in U. S. Pat. 6,025,353, the entire disclosure of which is incorporated herein by reference. According to U. S. Pat. 6,025,353, such disorders include, for example, metastasis, corneal graft rejection, ocular neovascularization, retinal neovascularization, diabetic retinopathy, retrolental fibroplasia, neovascular glaucoma, gastric ulcer, infantile hemaginomas, angiofibroma of the nasopharynx, avascular necrosis of bone, and endometriosis.

D. Treatment of Age-related Senile Dementia

[0134] The compounds of the invention may also be useful in the treatment of age-related senile dementia, including, for example, Alzheimer's Disease (AD) and presenile dementia.

[0135] Recent findings have shown a relationship between levels of vascular endothelial growth factor (VEGF) and severity of disease symptoms, both in patients with vascular dementia (VAD) and AD. See, Tarkowski et al., Neurobiol Aging, 2002, 23(2), page 237-43, the entire disclosure of which is incorporated herein by reference. The investigation of patterns of local release of VEGF and transforming growth factor-beta (TGF-beta) in a group of patients with AD and VAD suggests that vascular factors may have a role in the pathogenesis of AD as well as VAD.

II. Isomerism in Compounds of the Invention

A. Geometric Isomerism

[0136] Compounds according to Formula I, IA, IB and IC are characterized by isomerism resulting from the presence of two carbon-carbon double bonds. This isomerism is commonly referred to as cis-trans isomerism, but the more comprehensive naming convention employs (E)- and (Z)- designations. The compounds are named according to the Cahn-Ingold-Prelog system, the IUPAC 1974 Recommendations, Section E: Stereochemistry, in Nomenclature of Organic Chemistry, John Wiley & Sons, Inc., New York, NY, 4th ed., 1992, p. 127-138, the entire contents of which is incorporated herein by reference. Using this system of nomenclature, the four groups about a double bond are prioritized according to a series of rules. Then, that isomer with the two higher ranking groups on the same side of the double bond is designated Z (for the German word "zusammen", meaning together). The other isomer, in which the two higher-ranking groups are on opposite sides of the double bond, is designated E (for the German word "entgegen", which means "opposite"). Thus, if the four groups on a carbon-carbon double bond are ranked, A being the lowest rank and D being highest, A > B > C > D, the isomers would be named as in Scheme 4.

[0137] Unless otherwise indicated, both configurations of the carbon-carbon double bonds are included in the scope of the compounds according to the invention, except that the double bonds represented by M¹ and M² in Formulae I, IA, IB and IC may not both be in the (Z) configuration in the same compound.

B. Optical Isomerism

[0138] The present invention is also directed to isolated optical isomers of compounds according to Formulae I, IA, IB and IC. The isomers resulting from the presence of a chiral center comprise a pair of non-superimposable isomers that are called "enantiomers." Single enantiomers of a pure compound are optically active, i.e., they are capable of rotating the plane of plane polarized light. Single enantiomers are designated according to the Cahn-Ingold-Prelog system. See March, Advanced Organic Chemistry, 4th Ed., (1992), p. 109. Once the priority ranking of the four groups is determined, the molecule is oriented so that the lowest ranking group is pointed away from the viewer. Then, if the descending rank order of the other groups proceeds clockwise, the molecule is designated (R) and if the descending rank of the other groups proceeds counterclockwise, the molecule is designated (S). In the example in Scheme 7, the Cahn-Ingold-Prelog ranking is A > B > C > D. The lowest ranking atom, D is oriented away from the viewer.

[0139] The present invention is meant to encompass diastereomers as well as their racemic and resolved, diastereomerically and enantiomerically pure forms and salts thereof. Diastereomeric pairs may be resolved by known separation techniques including normal and reverse phase chromatography, and crystallization.

Example 20: Effect of α,β-Unsaturated Sulfones of Formula I on Tumor Cell Lines

A. Cells.

[0205] The effect of compounds according to Formula I on the growth of human tumor cells in culture was evaluated using the androgen receptor negative prostate (DU145) cell line. The cell culture was maintained at 37°C in a humidified atmosphere of 5% CO₂.

B. Treatment of Cells with Compounds According to Formula I

[0206] Cells were treated with compounds according to Formula I at five different concentrations (1-100 µM range) for each compound. For comparison, the cells were treated with curcumin at the same concentrations. The dose response was established by determining the number of viable cells after 96 h of continuous treatment against each of the different test concentrations of each compound. The determination of viable cells was done by the Trypan blue exclusion method. Activity for each compound at each concentration is reported as a percentage of cells that remain viable.

[0207] Table 3 shows the GI₅₀ values, i.e., the concentration of each compound required to inhibit the growth of each tumor cell line by 50%, determined for each tested compound. The GI₅₀ values were determined by direct extrapolation from each dose response curve.

Example 21: Inhibition of FLT1 by α,β-Unsaturated Sulfones of Formula I

[0208] The inhibition of FLT1 by compounds according to Formula I was assessed by employing an in vitro filter assay for FLT1.

[0209] Compounds 1-15 were prepared as 10mmol stock solutions in DMSO. Curcumin was also prepared as a 10mmol stock solution for testing in the FLT1 assay. Five units of recombinant FLT1 active protein was incubated with different concentrations of each compound in a 15µl reaction mixture (50 mM HEPES, 10mM MgCl₂, 1mM EDTA, 2mM Dithiothreitol 0.01% NP-40 pH 7.5) for 30 minutes at room temperature (25°C). Kinase reactions were performed for 20 minutes at 30°C in a volume of 20µl (15µl enzyme + compound of Formula 1,2µl 1mM ATP (100µM final concentration), 2µl of γ 32^pATP (40 µci final concentration) and 250µM of IGF-1Rtide. 10µl aliquots of the kinase reaction were spotted onto the center of a filter (2cm X 2cm P81 phosphocellulose paper square). After 30 seconds, the filters were washed with 0.75% phosphoric acid (3 x 5 minutes) and once with acetone (5 minutes). The wet filters were transferred into a scintillation vial containing scintillation cocktail ³²P (5 mL). Radioactivity was determined using a scintillation counter. Control analyses were performed with DMSO stock solutions containing no compound. Binding values were corrected for non-specific binding by performing duplicate assays in the absence of FLT1 enzyme and subtracting the non-specific binding values from the values obtained in the presence of FLT1. Counts per minute (CPM) of aliquots containing a compound of Formula I were compared with CPM of control samples. The kinase activity is expressed in percent of the maximal kinase activity. Dose response curves were plotted for each compound tested and were used to calculate IC_50's for the compounds which are listed below in Table 2. All assays were carried out in triplicate.

[0210] The results of the assay show that the compounds of the invention demonstrate a pattern of activity in the FLT1 assay wherein some compounds of Formula I are up to 450 times as potent as curcumin in inhibiting the activity of FLT1.
