FIELD OF THE INVENTION [0002] This invention is in the field of medicinal chemistry. In particular, the invention relates to compounds that are activators of caspases and inducers of apoptosis. The invention also relates to the use of these compounds as therapeutically effective anti-cancer agents.

TECHNICAL BACKGROUND

[0003] Organisms eliminate unwanted cells by a process variously known as regulated cell death, programmed cell death or apoptosis. Such cell death occurs as a normal aspect of animal development, as well as in tissue homeostasis and aging (Glucksmann, A., Biol Rev. Cambridge Philos. Soc. 26:59-86 (1951); Glucksmann, A., Archives de Biologie 76:419-431 (1965); Ellis, et al, Dev. 112:591-603 (1991); Vaux, et al, Cell 76:111-119 (1994)). Apoptosis regulates cell number, facilitates morphogenesis, removes harmful or otherwise abnormal cells and eliminates cells that have already performed their function. Additionally, apoptosis occurs in response to various physiological stresses, such as hypoxia or ischemia (PCT published application WO96/20721).

[0004] There are a number of morphological changes shared by cells experiencing regulated cell death, including plasma and nuclear membrane blebbing, cell shrinkage (condensation of nucleoplasm and cytoplasm), organelle relocalization and compaction, chromatin condensation and production of apoptotic bodies (membrane enclosed particles containing intracellular material) (Orrenius, S., J. Internal Medicine 237:529-536 (1995)).

[0005] Apoptosis is achieved through an endogenous mechanism of cellular suicide (Wyllie, A.H., in Cell Death in Biology and Pathology, Bowen and Lockshin, eds., Chapman and Hall (1981), pp. 9-34). A cell activates its internally encoded suicide program as a result of either internal or external signals. The suicide program is executed through the activation of a carefully regulated genetic program (Wyllie, et al, Int. Rev. Cyt 68:251 (1980); Ellis, et al, Ann. Rev. Cell Bio. 7:663 (1991)). Apoptotic cells and bodies are usually recognized and cleared by neighboring cells or macrophages before lysis. Because of this clearance mechanism, inflammation is not induced despite the clearance of great numbers of cells (Orrenius, S., J. Internal Medicine 237:529-536 (1995)).

[0006] It has been found that a group of proteases are a key element in apoptosis (see, e.g., Thornberry, Chemistry and Biology 5:R97-R103 (1998); Thornberry, British Med. Bull. 53:478-490 (1996)). Genetic studies in the nematode Caenorhabditis elegans revealed that apoptotic cell death involves at least 14 genes, 2 of which are the pro-apoptotic (death-promoting) ced (for cell death abnormal) genes, ced-3 and ced-4. CED-3 is homologous to interleukin 1 beta-converting enzyme, a cysteine protease, which is now called caspase- 1. When these data were ultimately applied to mammals, and upon further extensive investigation, it was found that the mammalian apoptosis system appears to involve a cascade of caspases, or a system that behaves like a cascade of caspases. At present, the caspase family of cysteine proteases comprises 14 different members, and more may be discovered in the future. All known caspases are synthesized as zymogens that require cleavage at an aspartyl residue prior to forming the active enzyme. Thus, caspases are capable of activating other caspases, in the manner of an amplifying cascade.

[0007] Apoptosis and caspases are thought to be crucial in the development of cancer (Apoptosis and Cancer Chemotherapy, Hickman and Dive, eds., Humana Press (1999)). There is mounting evidence that cancer cells, while containing caspases, lack parts of the molecular machinery that activates the caspase cascade. This makes the cancer cells lose their capacity to undergo cellular suicide and the cells become cancerous. In the case of the apoptosis process, Control points are known to exist that represent points for intervention leading to activation. These control points include the CED-9-BCL-like and CED-3 -ICE-like gene family products, which are intrinsic proteins regulating the decision of a cell to survive or die and executing part of the cell death process itself, respectively (see, Schmitt, et al, Biochem. Cell. Biol. 75:301-314 (1997)). BCL-like proteins include BCL-xL and BAX-alpha, which appear to function upstream of caspase activation. BCL-xL appears to prevent activation of the apoptotic protease cascade, whereas BAX-alpha accelerates activation of the apoptotic protease cascade.

[0008] It has been shown that chemotherapeutic (anti-cancer) drugs can trigger cancer cells to undergo suicide by activating the dormant caspase cascade. This may be a crucial aspect of the mode of action of most, if not all, known anticancer drugs (Los, et al, Blood 90:3118-3129 (1997); Friesen, et al, Nat. Med. 2:514 (1996)). The mechanism of action of current antineoplastic drugs frequently involves an attack at specific phases of the cell cycle. In brief, the cell cycle refers to the stages through which cells normally progress during their lifetime. Normally, cells exist in a resting phase termed G₀. During multiplication, cells progress to a stage in which DNA synthesis occurs, termed S. Later, cell division, or mitosis occurs, in a phase called M. Antineoplastic drugs, such as cytosine arabinoside, hydroxyurea, 6-mercaptopurine, and methotrexate are S phase specific, whereas antineoplastic drugs, such as vincristine, vinblastine, and paclitaxel are M phase specific. M phase specific antineoplastic drugs, such as vinblastine and paclitaxel, are known to affect tubulin polymerization. The ability of cells to appropriately polymerize and depolymerize tubulin is thought to be an important activity for M phase cell division.

[0009] Many slow growing tumors, e.g. colon cancers, exist primarily in the G₀ phase, whereas rapidly proliferating normal tissues, for example bone marrow, exist primarily in the S or M phase. Thus, a drug like 6-mercaptopurine can cause bone marrow toxicity while remaining ineffective for a slow growing tumor. Further aspects of the chemotherapy of neoplastic diseases are known to those skilled in the art (see, e.g., Hardman, et al, eds., Goodman and Gilman's The Pharmacological Basis of Therapeutics, Ninth Edition, McGraw-Hill, New York (1996), pp. 1225- 1287). Thus, it is clear that the possibility exists for the activation of the caspase cascade, although the exact mechanisms for doing so are not clear at this point. It is equally clear that insufficient activity of the caspase cascade and consequent apoptotic events are implicated in various types of cancer. The development of caspase cascade activators and inducers of apoptosis is a highly desirable goal in the development of therapeutically effective antineoplastic agents. Moreover, since autoimmune disease and certain degenerative diseases also involve the proliferation of abnormal cells, therapeutic treatment for these diseases could also involve the enhancement of the apoptotic process through the administration of appropriate caspase cascade activators and inducers of apoptosis.

Introduction of an amino group to the 2-position (Ri = NH₂, R₂ = 3'-Br, R₃ = H) also resulted in over 18,000-fold loss of potency (IC₅₀ >10,000 nM).

[00316] It has been reported that prenyl-protein transferase inhibitors, such as farnesyl protein transferase inhibitor RI 15777, possess preclinical antitumor activity against human breast cancer (Kelland, L.R., et. al, Clin. Cancer Res. 7:3544-3550 (2001)). Synergy of the protein farnesyltransferase inhibitor SCH66336 and cisplatin in human cancer cell lines also has been reported (Adjei, A. A., et al, Clin. Cancer.

[00317] It has been reported that cyclin-dependent kinase (CDK) inhibitors, such as flavopiridol, have potent synergetic effect in combination with other anticancer agents, such as CPT-11, a DNA topoisomerase I inhibitor in human colon cancer cells (Motwani, M., et al, Clin. Cancer Res. 7:4209-4219, (2001)). Therefore, another embodiment of the present invention is directed to a composition effective to inhibit neoplasia comprising a compound, or a pharmaceutically acceptable salt or prodrug of a compound described herein, which functions as a caspase cascade activator and inducer of apoptosis or inhibitor of tubulin polymerization, in combination with at least one known cyclin-dependent kinase inhibitor, or a pharmaceutically acceptable salt of said agent.

[00318] It has been reported that in preclinical studies COX-2 inhibitors were found to block angiogenesis, suppress solid tumor metastases, and slow the growth of implanted gastrointestinal cancer cells (Blanke, C. D., Oncology (Huntingt) 16 No. 4 Suppl. 3): 17-21 (2002)). Therefore, another embodiment of the present invention is directed to a composition effective to inhibit neoplasia comprising a compound, or a pharmaceutically acceptable salt or prodrug of a compound described herein, which ftmctions as a caspase cascade activator and inducer of apoptosis or inhibitor of tubulin polymerization, in combination with at least one known COX-2 inhibitor, or a pharmaceutically acceptable salt of said inhibitor.

[00322] A wide range of immune mechanisms operate rapidly following exposure to an infectious agent. Depending on the type of infection, rapid clonal expansion of the T and B lymphocytes occurs to combat the infection. The elimination of the effector cells following an infection is one of the major mechanisms for maintaining immune homeostasis. The elimination of the effector cells has been shown to be regulated by apoptosis. Autoimmune diseases have lately been determined to occur as a consequence of deregulated cell death. In certain autoimmune diseases, the immune system directs its powerful cytotoxic effector mechanisms against specialized cells, such as oligodendrocytes in multiple sclerosis, the beta cells of the pancreas in diabetes mellitus, and thyrocytes in Hashimoto's thyroiditis (Ohsako, S. & Elkon, K.B., Cell Death Differ. 6:13-21 (1999)). Mutations of the gene encoding the lymphocyte apoptosis receptor Fas/APO-l/CD95 are reported to be associated with defective lymphocyte apoptosis and autoimmune lymphoproliferative syndrome (ALPS), which is characterized by chronic, histologically benign splenomegaly, generalized lymphadenopafhy, hypergammaglobulinemia, and autoantibody formation. (Infante, A.J., et al, J. Pediatr. 133:629-633 (1998) and Vaishnaw, A.K., et al, J. Clin. Invest. 103:355-363 (1999)). It was reported that overexpression of Bcl-2, which is a member of the bcl-2 gene family of programmed cell death regulators with anti-apoptotic activity, in developing B cells of transgenic mice, in the presence of T cell dependent costimulatory signals, results in the generation of a modified B cell repertoire and in the production of pathogenic autoantibodies (Lopez-Hoyos, M., et al, Int. J. Mol. Med. 7:475-483 (1998)). It is therefore evident that many types of autoimmune disease are caused by defects of the apoptotic process. One treatment strategy for such diseases is to turn on apoptosis in the lymphocytes that are causing the autoimmune disease (O'Reilly, L.A. & Strasser, A., Inflamm. Res. 48:5-21 (1999)).

[00323] Fas-Fas ligand (FasL) interaction is known to be required for the maintenance of immune homeostasis. Experimental autoimmune thyroiditis (EAT), characterized by autoreactive T and B cell responses and a marked lymphocytic infiltration of the thyroid, is a good model to study the therapeutic effects of FasL. Batteux, F., et al, (J. Immunol. 162:603-60 _ (1999)) reported that by direct injection of DNA expression vectors encoding FasL into the inflamed thyroid, the development of lymphocytic infiltration of the thyroid was inhibited and induction of infiltrating T cells death was observed. These results show that FasL expression on thyrocytes may have a curative effect on ongoing EAT by inducing death of pathogenic autoreactive infiltrating T lymphocytes.

[00324] Bisindolyimaleimide VIII is known to potentiate Fas-mediated apoptosis in human astrocytoma 1321N1 cells and in Molt-4T cells; both of which were resistant to apoptosis induced by anti-Fas antibody in the absence of bisindolyimaleimide VIII. Potentiation of Fas-mediated apoptosis by bisindolyimaleimide VIII was reported to be selective for activated, rather than non-activated, T cells, and was Fas- dependent. Zhou T., et al, (Nat. Med. 5:42-48 (1999)) reported that administration of bisindolyimaleimide VIII to rats during autoantigen stimulation prevented the development of symptoms of T cell-mediated autoimmune diseases in two models, the Lewis rat model of experimental allergic encephalitis and the Lewis adjuvant arthritis model. Therefore, the application of a Fas-dependent apoptosis enhancer, such as bisindolyimaleimide VIII, may be therapeutically useful for the more effective elimination of detrimental cells and inhibition of T cell-mediated autoimmune diseases. Therefore, an effective amount of a compound, or a pharmaceutically acceptable salt or prodrug of the compound of Formulae I-Vc, which functions as a caspase cascade activator and inducer of apoptosis, is an effective treatment for autoimmune diseases.

[00325] Psoriasis is a chronic skin disease that is characterized by scaly red patches. Psoralen plus ultraviolet A (PUVA) is a widely used and effective treatment for psoriasis vulgaris. Coven, et al, Photodermatol Photoimmunol Photomed. 15:22- 27 (1999), reported that lymphocytes treated with psoralen 8-MOP or TMP and UVA, displayed DNA degradation patterns typical of apoptotic cell death. Ozawa, et al, J. Exp. Med. 189:111-11 (1999) reported that induction of T cell apoptosis could be the main mechanism by which 312-nm UVB resolves psoriasis skin lesions. Low doses of methotrexate may be used to treat psoriasis to restore a clinically normal skin. Heenen, et al, Arch. Dermatol Res. 290:240-245 (1998), reported that low doses of methotrexate may induce apoptosis and that this mode of action could explain the reduction in epidermal hyperplasia during treatment of psoriasis with methotrexate. Therefore, an effective amount of a compound, or a pharmaceutically acceptable salt or prodrug of the compound of Formulae I-Vc, which functions as a caspase cascade activator and inducer of apoptosis, is an effective treatment for hyperproliferative skin diseases, such as psoriasis.

[00326] Synovial cell hyperplasia is a characteristic of patients with rheumatoid arthritis (RA). It is believed that excessive proliferation of RA synovial cells, as well as defects in synovial cell death, may be responsible for synovial cell hyperplasia. Wakisaka, et al, Clin. Exp. Immunol. 114:119-12 (1998), found that although RA synovial cells could die via apoptosis through a Fas/FasL pathway, apoptosis of synovial cells was inhibited by proinflammatory cytokines present within the synovium. Wakisaka, et al also suggested that inhibition of apoptosis by the proinflammatory cytokines may contribute to the outgrowth of synovial cells, and lead to pannus formation and the destruction of joints in patients with RA. Therefore, an effective amount of a compound, or a pharmaceutically acceptable salt or prodrug of the compound of Formulae I-Vc, which functions as a caspase cascade activator and inducer of apoptosis, is an effective treatment for rheumatoid arthritis.

[00327] There has been an accumulation of convincing evidence that apoptosis plays a major role in promoting resolution of the acute inflammatory response. Neutrophils are constitutively programmed to undergo apoptosis, thus limiting their pro- inflammatory potential and leading to rapid, specific, and non-phlogistic recognition by macrophages and semi-professional phagocytes (Savill, J., J. Leukoc. Biol. 61:315-380 (1997)). Boirivant, et al, Gastroenterology 116:551-565 (1999), reported that lamina propria T cells, isolated from areas of inflammation in Crohn's disease, ulcerative colitis, and other inflammatory states, manifest decreased CD2 pathway-induced apoptosis. In addition, studies of cells from inflamed Crohn's disease tissue indicate that this defect is accompanied by elevated Bcl-2 levels. Therefore, an effective amount of a compound, or a pharmaceutically acceptable salt or prodrug of the compound of Formulae I-Vc, which functions as a caspase cascade activator and inducer of apoptosis, is an effective treatment for inflammation.

[00328] Caspase cascade activators and inducers of apoptosis may also be a desirable therapy in the elimination of pathogens, such as H1N, Hepatitis C and other viral pathogens. The long lasting quiecence, followed by disease progression, may be explained by an anti-apoptotic mechanism of these pathogens leading to persistent cellular reservoirs of the virions. It has been reported that H1N-1 infected T leukemia cells or peripheral blood mononuclear cells (PBMCs) underwent enhanced viral replication in the presence of the caspase inhibitor Z-VAD-fmk. Furthermore, Z- VAD-fmk also stimulated endogenous virus production in activated PBMCs derived from HIV- 1 -infected asymptomatic individuals (Chinnaiyan, A., et al, Nat Med. 3:333 (1997)). Therefore, apoptosis serves as a beneficial host mechanism to limit the spread of HIV and new therapeutics using caspase/apoptosis activators are useful to clear viral reservoirs from the infected individuals. Similarly, HCV infection also triggers anti-apoptotic mechanisms to evade the host's immune surveillance leading to viral persistence and hepatocarcinogenesis (Tai, D.I., et al. Hepalology 5:656-64 (2000)). Therefore, apoptosis inducers are useful as therapeutics for H1N, HCV, HBV, and other infectious disease.

[00329] Stent implantation has become the new standard angioplasty procedure. However, in-stent restenosis remains the major limitation of coronary stenting. New approaches have been developed to target pharmacological modulation of local vascular biology by local administration of drugs. This allows for drug applications at the precise site and time of vessel injury. Numerous pharmacological agents with antiproliferative properties are currently under clinical investigation, including actinomycin D, rapamycin or paclitaxel coated stents (Regar E., et al, Br. Med. Bull. 59:227-248 (2001)). Therefore, apoptosis inducers, which are antiproliferative, are useful as therapeutics for the prevention or reduction of in-stent restenosis.

[00330] Another important aspect of the present invention is the surprising discovery that compounds of the present invention are potent and highly efficacious activators of caspase-3, inhibitors of tubulin polymerization, and inhibitors of topoisomerase even in drug resistant cancer cells, which enables these compounds to inhibit the growth and proliferation of drug resistant cancer cells, and to cause apoptosis and cell death in the drug resistant cancer cells. Specifically, the compounds of the present invention are not substrates for the MDR transporters such as Pgp-1 (MDR- 1), MRP-1 and BCRP. This is particularly surprising in view of the fact that almost all of the commercially available tubulin-interacting chemotherapeutics are substrates for multidrug resistance transporters (MDRs).

[00331] Multidrug resistance is the major cause of chemotherapy failure. Drug resistance is typically caused by ATP-dependent efflux of drug from cells by ATP- binding cassette (ABC) transporters. In particular, the ABC transporters ABCB1 (MDR-1, P glycoprotein); ABCC1 (MRP1); and ABCG2 (BCRP, MXR) are typically over-expressed in drug resistant tumors and thus are implicated in drug resistance. In comparison to most standard anti-cancer drugs, which are not effective in killing drug resistant cancer cells, the compounds of the present invention are effective in killing drug resistant cancer cells. Therefore, compounds of this invention are useful for the treatment of drug resistant cancer.

[00332] Thus, another aspect of the present invention is the application of the methods and compounds of the present invention as described above to tumors that have acquired resistance to other anticancer drugs. In one embodiment, a compound of the present invention is administered to a cancer patient who has been treated with another anti-cancer drug. In another embodiment, a compound of the present invention is administered to a patient who has been treated with and is not responsive to another anti-cancer drug or developed resistance to such other anti-cancer compound. In another embodiment, a compound of the present invention is administered to a patient who has been treated with another anti-cancer drug and is refractory to said other anti-cancer drug. The compounds of the present invention can be used in treating cancer in a patient who is not responsive or is resistant to any other anti-cancer agent. Examples of such other anti-cancer agent may include alkylating agents, antimitotic agents, topo I inhibitors, topo II inhibitors, RNA/DNA antimetabolites, EGFR inhibitors, angiogenesis inhibitors, tubulin inhibitors (e.g., vinblastine, taxol® (paclitaxel), and analogues thereof), proteosome inhibitors, etc., some of the exemplary compounds of which are provided above and are general known in the art, e.g., melphalan, chlorambucil, cyclophosamide, ifosfamide, vincristine, mitoguazone, epirubicin, aclarubicin, bleomycin, mitoxantrone, elliptinium, fludarabine, octreotide, retinoic acid, tamoxifen, Gleevec® (imatinib mesylate) and alanosine. The compounds can be used in treating patients having any type of diseases responsive to the inhibition of tubulin or inhibition of topoisomerase (including but not limited to the types of cancer described above) who are not responsive or become resistant to another therapeutic agent, e.g., another anti-cancer agent.

[00333] Pharmaceutical compositions within the scope of this invention include all compositions wherein the compounds of the present invention are contained in an amount that is effective to achieve its intended purpose. While individual needs vary, determination of optimal ranges of effective amounts of each component is within the skill of the art. Typically, the compounds may be administered to animals, e.g., mammals, orally at a dose of 0.0025 to 50 mg/kg of body weight, per day, or an equivalent amount of the pharmaceutically acceptable salt thereof, to a mammal being treated. Preferably, approximately 0.01 to approximately 10 mg/kg of body weight is orally administered. For intramuscular injection, the dose is generally approximately one-half of the oral dose. For example, a suitable intramuscular dose would be approximately 0.0025 to approximately 25 mg/kg of body weight, and most preferably, from approximately 0.01 to approximately 5 mg/kg of body weight. If a known cancer chemotherapeutic agent is also administered, it is administered in an amount that is effective to achieve its intended purpose. The amounts of such known cancer chemotherapeutic agents effective for cancer are well known to those skilled in the art.

[00334] The unit oral dose may comprise from approximately 0.01 to approximately 50 mg, preferably approximately 0J to approximately 10 mg of the compound of the invention. The unit dose may be administered one or more times daily, as one or more tablets, each containing from approximately 0J to approximately 10 mg, conveniently approximately 0.25 to 50 mg of the compound or its solvates.

[00335] In a topical formulation, the compound may be present at a concentration of approximately 0.01 to 100 mg per gram of carrier. [00336] In addition to administering the compound as a raw chemical, the compounds of the invention may be administered as part of a pharmaceutical preparation containing suitable pharmaceutically acceptable carriers comprising excipients and auxiliaries, which facilitate processing of the compounds into preparations that may be used pharmaceutically. Preferably, the preparations, particularly those preparations which may be administered orally and that may be used for the preferred type of administration, such as tablets, dragees, and capsules, and also preparations that may be administered rectally, such as suppositories, as well as suitable solutions for administration by injection or orally, contain from approximately 0.01 to 99 percent, preferably from approximately 0.25 to 75 percent of active compound(s), together with the excipient.

[00337] Also included within the scope of the present invention are the non-toxic pharmaceutically acceptable salts of the compounds of the present invention. Acid addition salts are formed by mixing a solution of the compounds of the present invention with a solution of a pharmaceutically acceptable non-toxic acid, such as hydrochloric acid, fumaric acid, maleic acid, succinic acid, acetic acid, citric acid, tartaric acid, carbonic acid, phosphoric acid, oxalic acid, and the like. Basic salts are formed by mixing a solution of the compounds of the present invention with a solution of a pharmaceutically acceptable non-toxic base, such as sodium hydroxide, potassium hydroxide, choline hydroxide, sodium carbonate, Tris, N-methyl- glucamine and the like.

[00338] The pharmaceutical compositions of the invention may be administered to any animal, which may experience the beneficial effects of the compounds of the invention. Foremost among such animals are mammals, e.g., humans and veterinary animals, although the invention is not intended to be so limited.

[00339] The pharmaceutical compositions of the present invention may be administered by any means that achieve their intended purpose. For example, administration may be by parenteral, subcutaneous, intravenous, intramuscular, intraperitoneal, transdermal, buccal, intrathecal, intracranial, intranasal or topical routes. Alternatively, or concurrently, administration may be by the oral route. The dosage administered will be dependent upon the age, health, and weight of the recipient, kind of concurrent treatment, if any, frequency of treatment, and the nature of the effect desired.

[00340] The pharmaceutical preparations of the present invention are manufactured in a manner, which is itself known, e.g., by means of conventional mixing, granulating, dragee-making, dissolving, or lyophilizing processes. Thus, pharmaceutical preparations for oral use may be obtained by combining the active compounds with solid excipients, optionally grinding the resulting mixture and processing the mixture of granules, after adding suitable auxiliaries, if desired or necessary, to obtain tablets or dragee cores.

[00341] Suitable excipients are, in particular: fillers, such as saccharides, e.g. lactose or sucrose, mannitol or sorbitol; cellulose preparations and/or calcium phosphates, e.g. tricalcium phosphate or calcium hydrogen phosphate; as well as binders, such as starch paste, using, e.g., maize starch, wheat starch, rice starch, potato starch, gelatin, tragacanth, methyl cellulose, hydroxypropylmethylcellulose, sodium carboxymethylcellulose, and/or polyvinyl pyrrolidone. If desired, disintegrating agents may be added, such as the above-mentioned starches and also carboxymethyl- starch, cross-linked polyvinyl pyrrolidone, agar, or alginic acid or a salt thereof, such as sodium alginate. Auxiliaries are, above all, flow-regulating agents and lubricants, e.g., silica, talc, stearic acid or salts thereof, such as magnesium stearate or calcium stearate, and/or polyethylene glycol. Dragee cores are provided with suitable coatings which, if desired, are resistant to gastric juices. For this purpose, concentrated saccharide solutions may be used, which may optionally contain gum arabic, talc, polyvinyl pyrrolidone, polyethylene glycol and/or titanium dioxide, lacquer solutions and suitable organic solvents or solvent mixtures. In order to produce coatings resistant to gastric juices, solutions of suitable cellulose preparations, such as acetylcellulose phthalate or hydroxypropymethyl-cellulose phthalate, are used. Dye stuffs or pigments may be added to the tablets or dragee coatings, e.g., for identification or in order to characterize combinations of active compound doses.

[00342] Other pharmaceutical preparations, which may be used orally include push- fit capsules made of gelatin, as well as soft, sealed capsules made of gelatin and a plasticizer, such as glycerol or sorbitol. The push-fit capsules may contain the active compounds in the form of: granules, which may be mixed with fillers, such as lactose; binders, such as starches; and/or lubricants, such as talc or magnesium stearate and, optionally, stabilizers. In soft capsules, the active compounds are preferably dissolved or suspended in suitable liquids, such as fatty oils, or liquid paraffin. In addition, stabilizers may be added.

[00343] Possible pharmaceutical preparations, which may be used rectally include, e.g., suppositories, which consist of a combination of one or more of the active compounds with a suppository base. Suitable suppository bases are, e.g., natural or synthetic triglycerides, or paraffin hydrocarbons. In addition, it is also possible to use gelatin rectal capsules, which consist of a combination of the active compounds with a base. Possible base materials include, e.g., liquid triglycerides, polyethylene glycols, or paraffin hydrocarbons.

[00344] Suitable formulations for parenteral administration include aqueous solutions of the active compounds in water-soluble form, e.g., water-soluble salts and alkaline solutions. In addition, suspensions of the active compounds as appropriate oily injection suspensions may be administered. Suitable lipophilic solvents or vehicles include fatty oils, e.g., sesame oil, or synthetic fatty acid esters, e.g., ethyl oleate or triglycerides or polyethylene glycol-400 (the compounds are soluble in PEG-400), or cremophor, or cyclodextrins. Aqueous injection suspensions may contain substances which increase the viscosity of the suspension include, e.g., sodium carboxymethyl cellulose, sorbitol, and/or dextran. Optionally, the suspension may also contain stabilizers.

[00345] In accordance with one aspect of the present invention, compounds of the invention are employed in topical and parenteral formulations and are used for the treatment of skin cancer.

[00346] The topical compositions of this invention are formulated preferably as oils, creams, lotions, ointments and the like by choice of appropriate carriers. Suitable carriers include vegetable or mineral oils, white petrolatum (white soft paraffin), branched chain fats or oils, animal fats and high molecular weight alcohol (greater than Cι₂). The preferred carriers are those in which the active ingredient is soluble. Emulsifrers, stabilizers, humectants and antioxidants may also be included, as well as agents imparting color or fragrance, if desired. Additionally, transdermal penetration enhancers may be employed in these topical formulations. Examples of such enhancers are found in U.S. Patent Nos. 3,989,816 and 4,444,762.

[00347] Creams are preferably formulated from a mixture of mineral oil, self- emulsifying beeswax and water in which mixture of the active ingredient, dissolved in a small amount of an oil, such as almond oil, is admixed. A typical example of such a cream is one which includes approximately 40 parts water, approximately 20 parts beeswax, approximately 40 parts mineral oil and approximately 1 part almond oil.

[00348] Ointments may be formulated by mixing a solution of the active ingredient in a vegetable oil, such as almond oil, with warm soft paraffin and allowing the mixture to cool. A typical example of such an ointment is one which includes approximately 30 % almond oil and approximately 70 % white soft paraffin by weight.

[00349] The following examples are illustrative, but not limiting, of the method and compositions of the present invention. Other suitable modifications and adaptations of the variety of conditions and parameters normally encountered in clinical therapy and which are obvious to those skilled in the art are within the spirit and scope of the invention.

T- 47D and DLD-1 cells were maintained at a cell density between 50 and 80 % confluency at a cell density of 0J to 0.6 x 10⁶ cells/mL. Cells were harvested at 600xg and resuspended at 0.65 x 10⁶ cells/mL into appropriate media + 10 % FCS. An aliquot of 22.5 μL of cells was added to a well of a 384-well microtiter plate containing 2.5 μL of a 10 % DMSO in RPMI-1640 media solution containing 0J6 to 100 μM of (2-chloro-quinazolin-4-yl)-(4-methoxy-phenyl)-methyl-amine or other test compound (0.016 to 10 μM final). An aliquot of 22.5 μL of cells was added to a well of a 384-well microtiter plate containing 2.5 μL of a 10 % DMSO in RPMI- 1640 media solution without test compound as the control sample. The samples were mixed by agitation and then incubated at 37 °C for 48 h in a 5 % CO₂-95 % humidity incubator. After incubation, the samples were removed from the incubator and 25 μL of a solution containing 14 μM of N-(Ac-DEVD)-N'-ethoxycarbonyl- R110 fluorogenic substrate (Cytovia, Inc.; WO99/18856), 20 % sucrose (Sigma), 20 mM DTT (Sigma), 200 mM ΝaCl (Sigma), 40 mM Νa PIPES buffer pH 7.2 (Sigma), and 500 μg/mL lysolecithin (Calbiochem) was added. The samples were mixed by agitation and incubated at room temperature. Using a fluorescent plate reader (Model SPECTRAfluor Plus, Tecan), an initial reading (T = 0) was made approximately 1-2 min after addition of the substrate solution, employing excitation at 485 nm and emission at 530 nm, to determine the background fluorescence of the control sample. After the 3 h incubation, the samples were read for fluorescence as above (T = 3 h).

[00529] Calculation:

[00530] The Relative Fluorescence Unit values (RFU) were used to calculate the sample readings as follows: RFU ₍τ=3h) - Control RFU _{τ=o) = Net RFU_(T=3h) [00531] The activity of caspase cascade activation was determined by the ratio of the net RFU value for (2-chloro-quinazolin-4-yl)-(4-methoxy-phenyl)-methyl-amine or other test compounds to that of control samples. The EC₅₀ (nM) was determined by a sigmoidal dose-response calculation (Prism 3.0, GraphPad Software Inc.).

An aliquot of 45 μL of cells was added to a well of a 96-well microtiter plate containing 5 μL of a 10 %> DMSO in RPMI-1640 media solution without compound as the control sample for maximal cell proliferation (L_\i_ax)- The samples were mixed by agitation and then incubated at 37 °C for 48 h in a 5%> CO₂-95% humidity incubator. After incubation, the samples were removed from the incubator and 25 μL of CellTiter-Glo ™ reagent (Promega) was added. The samples were mixed by agitation and incubated at room temeperature for 10-15 min. Plates were then read using a luminescent plate reader (Model SPECTRAfluor Plus, Tecan) to give L_test values.

[00536] Baseline for GI₅₀ (dose for 50%> inhibition of cell proliferation) of initial cell numbers was determined by adding an aliquot of 45 μL of cells or 45 μL of media, respectively, to wells of a 96-well microtiter plate containing 5 μL of a 10% DMSO in RPMI-1640 media solution. The samples were mixed by agitation and then incubated at 37 °C for 0.5 h in a 5%> CO₂-95% humidity incubator. After incubation, the samples were removed from the incubator and 25 μL of CellTiter-Glo ™ reagent (Promega) was added.

EXAMPLE 145 Identification of (2-Chloro-quinazolin-4-yl)-(4-methoxy-phenyl)-methyl-amine and Analogs as Inhibitors of Tubulin Polymerization

[00540] Lyophilized tubulin (Cytoskeleton #ML113, 1 mg, MAP-rich) was assayed for the effect of the test compound on tubulin polymerization as measured by change in fluorescence for 4',6-diamidino-2-phenylindole (DAPI) (Baπon, D. M. et al. Analytical Biochem., 2003, 315, 49-56.). 1 μl of serial dilutions of each test compound (from lOOx DMSO stock) was added in 96 well plate format and preincubated for 30 minutes with 94 ul of the non-GTP supplemented tubulin supernatant. 5 μl of DAPI/GTP solution was added to initiate polymerization and incubated for 30 minutes at 37°C. Fluorescence was read with excitation 350 nm, emission wavelength 485 nm on a Tecan Spectraflour Plus. Polymerized tubulin (DMSO and with the tubulin stabilizer taxol® (paclitaxel)) gives a higher DAPI fluorescence as compared to non-polymerized tubulin (vinblastine and colchicine used to determine baseline). The IC₅₀ for tubulin inhibition was the concentration found to decrease the fluorescence of DAPI by 50%> as calculated with Prism 3.0. The IC50 are summarized in Table III.

Thus, (2-chloro-quinazolin-4-yl)-(4-methoxy-phenyl)-methyl-amine

(Example 1) and analogs are identified as potent inhibitors of tubulin polymerization and are thus useful in treating diseases and disorders discussed above. EXAMPLE 146 Identification of f 2-Chloro-quinazolin-4-yl)-(4-methoxy-phenylVmethyl-amine as a Cytotoxic Compound in Multidrug Resistant Cells

[00542] Cytotoxicity of compounds in multidrug resistant cells can be determined by administering compounds to cell lines that overexpress the multidrug resistance pump MDR-1 and determining the viability of the cell lines. NCI- ADR/Res and P388/ADR cell lines are known to over-express the multidrug resistance pump MDR-1 (also known as P-glycoprotein-1; Pgp-1); whereas MCF-7 and P388 cell lines do not overexpress the multidrug resistance pumps MDR-1, MRP-1, or BCRP.

[00543] NCI-ADR Res, MCF-7, P388, and P388/ADR cell lines were obtained from American Type Culture Collection (Manassas, NA) and maintained in RPMI-1640 media supplemented with 10% FCS, 10 units/ml penicillin and streptomycin, 2 mM Glutamax and ImM sodium pyruvate (Invitrogen Corporation, Carlsbad, CA). For compound testing, cells were plated in 96 well dishes at a concentration of 1.5 x 10⁴ cells/well. Cells were allowed to adhere to the plate overnight and then incubated with compounds at final concentrations ranging from 0J3nM to lOuM for 72 hours. Cell viability was then assessed using the ATP-lite reagent (Perkin Elmer, Foster City, CA). Plates were read on a Wallac Topcount luminescence reader (Perkin Elmer, Foster City, CA) and the results graphed in Prism software (Graphpad Software, Inc., San Diego, CA). Νon-linear regression with variable slope analysis was performed to obtain IC₅₀ concentration values.

[00544] Example 1 compound, docetaxel, and vinblastine were tested for their ability to kill multidrug resistant cells by administering the compounds to ΝCI-ADR/Res, MCF-7 cells, P388 and P388/ADR cells and determining the viability of the cells. Example 1 compound maintained nearly equal potency in all four cell lines, whereas known MDR-1 substrates vinblastine and docetaxel showed a loss of potency in the MDR-1 over-expressing cell lines as shown in Table IN below:

Table IN. Cytotoxicity of Exa 1 Cmpd in MDR-1 over-expressing cell lines

[00545] Thus, (2-chloro-quinazolin-4-yl)-(4-methoxy-phenyl)-methyl-amine is identified as a cytotoxic compound in multidrug resistant cells and is thus useful in treating diseases and disorders discussed above.

EXAMPLE 147 Propidium Iodide and Annexin V Flow Cvtometer-Based Assay To Detect Apoptosis

[00546] Νecrotic versus apoptotic killing of human cell lines by compounds can be determined using dual annexin V-FITC and propidium iodide (PI) staining. Flipping of phosphatidylserine to the outer leaflet of the plasma membrane is a characteristic of all apoptotic cells. AnnexinN is a serum protein that binds to phosphatidylserine in the presence of the divalent cations (calcium). PI is a DΝA stain that is excluded from live cells and is used to discriminate between cells with intact or damaged plasma membranes.

[00547] Cells are plated at varying densities in 6 well plates and treated with varying concentrations of compounds for 18-72 hours. Cells are grown in RPMI-1640 media supplemented with 10% FCS. DMSO concentrations do not exceed 0J %> v:v in any assay. All cells in the wells are harvested and rinsed IX with cold Hanks buffered saline solution (HBSS) containing calcium and magnesium (Invitrogen, Carlsbad CA). Carefully aspirate supernatant after the wash and resuspend in 100 μl Annexin V-FITC (Annexin V/PI Apoptosis Detection Kit; R & D Systems TA4638; Minneapolis, MΝ) in binding buffer (10 mM HEPES pH 7.4, 150mM ΝaCl, 5 mM KC1, 1 mM MgCl₂, 1.8 mM CaCl₂ and 2% bovine serum albumin w:v). Incubate in dark for 15 minutes on ice. Prior to analyzing samples, the volume is adjusted to 500 μl with IX Binding Buffer and 25 μl PI is added per sample. Staining can be quantified on a flow cytometer (Becton-Dickenson, Franklin Lake, NJ).

EXAMPLE 151 Identification of (2-Chloro-quinazolin-4-yl)-(4-methoxy-phenyl)-methyl-amine as an inhibitor of Topoisomerase

[00551] The ability of compounds to inhibit Topoisomerase II activity in relaxing supercoiled DNA can be determined by adding compounds to DNA samples and measuring the formation of topoisomers. The addition of Topoisomerase II to DNA samples results in the formation of topoisomers, which migrate faster than open circular DNA and slower than supercoiled DNA substrate when run on a gel. Ethidium Bromide, a known intercalator, and etoposide (VP16), a known topoisomerase II inhibitor, are used as controls.

[00552] Assay reagents were obtained from TopoGEN, Inc. (Columbus, Ohio). Samples were prepared by combining 10 μl of D/W, 2 μl of lOx TOPO II assay buffer, and 1 μl (0.25 μg) pRYG DNA. 5 μl of (2-Chloro-quinazolin-4-yl)-(4- methoxy-phenyl)-methyl-amine (Example 1 Compound), Ethidium Bromide, or VP16 were added to samples at varying concentrations. 2 μl of TOPO II (4 units in 20 μl reaction) was added to the samples and the samples were incubated at 37 °C in a water bath for 50 minutes. 2 μl of 10%) SDS was added and 0. Proteinase K (500 μg/ml) was added and the samples were incubated again at 37 °C in a water bath for 50 minutes. Half of the reaction was loaded on a 1% gel without ethidium bromide and run in 1XTAE buffer at 20 volts/cm for 2 hours. The gel was stained with 0.5 μg/ml Ethidium Bromide for 10 seconds and destained in D/W for 30 seconds. The resulting gel image is shown in Figure 1.

[00553] Inspection of the amount of supercoiled DNA present in the sample with lOOμM of Example 1 Compound indicates that inhibition of DNA relaxation is substantial. The results are consistent with topoisomerase II inhibition as well as with an effect of the compound not on topoisomerase II, but rather on the DNA itself, such as intercalation of the compound into the DNA substrate. In order to distinguish between direct inhibition of topoisomerase II activity and intercalation, the effect of Example 1 Compound is determined on topoisomerase I-mediated relaxation of supercoiled DNA.

[00554] Samples were prepared by combining 10 μl of D/W, 2 μl of lOx TOPO II assay buffer, and 1 μl (0.25 μg) Form I DNA. 5 μl of (2-Chloro-quinazolin-4-yl)-(4- methoxy-phenyl)-methyl-amine (Example 1 Compound), Ethidium Bromide, or VP16 were added to samples at varying concentrations. 1 μl of TOPO I (5 units in 20 μl reaction) was added to the samples and the samples were incubated at 37 °C in a water bath for 50 minutes. 2 μl of 10% SDS was added and 0. Proteinase K (500 μg/ml) was added and the samples were incubated again at 37 °C in a water bath for 50 minutes. Half of the reaction was loaded on a 1% gel without ethidium bromide and run in 1XTAE buffer at 20 volts/cm for 2 hours. The gel was stained with 0.5 μg/ml Ethidium Bromide for 10 seconds and destained in D/W for 30 seconds. The resulting gel image is shown in Figure 2. [00555] As shown in Figure 2, the known intercalator, Ethidium Bromide, completely eliminated topoisomerase I-dependent relaxation of supercoiled DNA, just as it eliminated topoisomerase Il-dependent relaxation of supercoiled DNA (see Figure 1). In contrast, Example 1 Compound and the known topoisomerase II inhibitor, VP- 16, have no apparent effect on topoisomerase I activity.

EXAMPLE 152 Identification of Radiolabeled (4- Azido-phenyl)-(2-methyl-quinazolin-4-yl)- methyl-amine and Analogs as inhibitors of Topoisomerase

[00556] 30 Units (15ul) Human Type II Topoisomerase (pi 70 Form) (from TopoGEN, Inc., Columbus, Ohio) was incubated with 50 nM radiolabeled Example 102 compound for 60 minutes at room temperature.

Radiolabeled Example 102 compound

[00557] (Radiolabeled Example 102 compound stock is 16.67 uM, 60 Ci/mmol, lmCi/ml American Radiolabeled Chemicals, Inc., St. Louis, MO. Samples were either UV irradiated (+) with a short wavelength UV Source (254 nm) for 10 minutes at a distance of 3.5 cm or not irradiated (-). 8ul of 5x sample buffer (150mM Tris, pH 6.8, 50%) glycerol, 1%SDS, 50 mM dithiothreitol, 62 mg/ml bromophenol blue) was added to the samples and boiled for 5 minutes. The entire sample was then loaded onto a 6%> Tris-Glycine SDS-gel (10 well, 1.5 mm thickness) (Invitrogen, Carlsbad, California). The gel was stained with 1% Coomassie Brilliant Blue in 40% methanol, 7.5% acetic acid for 2 hours then de-stained in several changes of de- stainer (40%> methanol, 7.5% acetic acid). The gel was then incubated in Amplify (Amersham, Piscataway, NJ) for 30 minutes at room temperature and then dried down on Whatman filter paper at 80° C for 2 hours on a gel dryer. The dried gel was put on Hyperfilm (Amersham) in a film cassette and placed at -80° C for 5-7 days. The resulting gel image is shown in Figure 3. These results indicate that the compound binds sufficiently well to Topoisomerase II to crosslink to the enzyme when photoactivated. Having now fully described this invention, it will be understood by those of ordinary skill in the art that the same can be performed within a wide and equivalent range of conditions, formulations and other parameters without affecting the scope of the invention or any embodiment thereof.
