Application Number:13/488,490
Patent Claims:1. A method of treating cancer in a subject in need thereof, comprising administering to the subject a composition comprising a therapeutically effective amount of a metallocene compound, and optionally a pharmaceutically acceptable diluent, excipient, or carrier; wherein the metallocene compound has the structure of formula CPH-1, CPH-2, CPH-3, CPH-4, CPH-5, CPH-6, CPH-7, CPH-8, CPH-9, CPH-10, CPH-11, CPH-12, CPH-13, CPH-14, or CPH-15, or a pharmaceutically acceptable salt thereof: ##STR00009## ##STR00010## ##STR00011## wherein the cancer is melanoma, lung, colon, urinary bladder, breast, renal, prostate, ovarian, cervical, or head and neck cancer.

2. A method of treating cancer in a subject in need thereof, comprising administering to the subject a composition comprising: a therapeutically effective amount of a metallocene compound having formula MET-B, or a pharmaceutically acceptable salt thereof: ##STR00012## and optionally a pharmaceutically acceptable diluent, excipient, or carrier; wherein: M is Ti, Zr, or Hf; each R.sup.X, R.sup.Y, and R.sup.Z independently is H, a halide, hydrocarbyl group, or halogenated hydrocarbyl group; E.sup.1 is C or Si; R.sup.1 and R.sup.2 are independently H or a hydrocarbyl group, or halogenated hydrocarbyl group; X.sup.1 and X.sup.2 are independently a monoanionic ligand; and q, r, and s are independently 0, 1, 2, 3, or 4; and wherein the cancer is melanoma, lung, colon, urinary bladder, breast, renal, prostate, ovarian, cervical, or head and neck cancer.

3. The method of claim 2, wherein the cancer is resistant or insensitive to treatment with one or more of alemtuzumab, aminoglutethimide, anastrozole, asparginase, bacillus calmette-guerin, bendamustine, bevacizumab, bicalutamide, bleomycin, bortezomib, brentuximab, cabazitaxel, capecitabine, carboplatin, carmustine, cervarix, cetuximab, cisplatin, cyclophosphamide, cytarabine, dacarbazine, dasatinib, daunorubicin, desarelix, dexamethasone, docetaxel, doxil, doxorubicin, epirubicin, erlotinib, etoposide, everolimus, exemestane, fadrozole, fludarabine, 5-fluorouracil, flutamide, fulvestrant, gardasil, gemcitabine, goserelin, ibritumomab, idarubicin, ifosfamide, il-2, imatinib, inlyta, interferon-alpha, ipilimumab, irinotecan, ixabepilone, lapatinib, lenalidomide, letrozole, leucovorin, leuprolide, lomustine, megestrol acetate, melphalan, methotrexate, 6-mercaptopurine, mitomycin-C, mitoxantrone, nilotinib, nilutamide, oxaliplatin, paclitaxel, panitumumab, pazopanib, pegasparginase, pemetrexed, procarbazine, raloxifene, rituximab, sorafenib, sunitinib, sylatron (Peg), tamoxifen, temozolomide, temsirolimus, thalidomide, thioguanine, thiotepa, topotecan, toremifene, tositumomab, trastuzumab, vemurafenib, vincristine, vinorelbine, vismodegib, and/or vorinostat.

4. The method of claim 2, wherein the cancer is resistant or insensitive to treatment with a platinum agent.

5. The method of claim 2, wherein the cancer is resistant or insensitive to treatment with a taxane.

6. The method of claim 1, wherein the subject is a human.

7. The method of claim 2, wherein: M is Zr or Hf; or at least one R.sup.X, R.sup.Y, or R.sup.Z is a C.sub.1 to C.sub.8 alkyl or C.sub.3 to C.sub.8 alkenyl group; or E.sup.1 is C; or at least one of R.sup.1 and R.sup.2 is an alkyl, alkenyl, or phenyl; or q, r, and s are independently 0, 1, or 2; or any combination thereof.

8. The method of claim 2, wherein: M is Zr or Hf; at least one R.sup.X, R.sup.Y, or R.sup.Z is a C.sub.1 to C.sub.8 alkyl or C.sub.3 to C.sub.8 alkenyl group; E.sup.1 is C; at least one of R.sup.1 and R.sup.2 is a phenyl group or an alkenyl group; q, r, and s are independently 0 or 1; and at least one of X.sup.1 and X.sup.2 is Cl.

9. The method of claim 2, wherein the composition is administered in combination with a therapeutically effective amount of a therapeutic agent, the therapeutic agent comprising alemtuzumab, aminoglutethimide, anastrozole, asparginase, bacillus calmette-guerin, bendamustine, bevacizumab, bicalutamide, bleomycin, bortezomib, brentuximab, cabazitaxel, capecitabine, carboplatin, carmustine, cervarix, cetuximab, cisplatin, cyclophosphamide, cytarabine, dacarbazine, dasatinib, daunorubicin, desarelix, dexamethasone, docetaxel, doxil, doxorubicin, epirubicin, erlotinib, etoposide, everolimus, exemestane, fadrozole, fludarabine, 5-fluorouracil, flutamide, fulvestrant, gardasil, gemcitabine, goserelin, ibritumomab, idarubicin, ifosfamide, il-2, imatinib, inlyta, interferon-alpha, ipilimumab, irinotecan, ixabepilone, lapatinib, lenalidomide, letrozole, leucovorin, leuprolide, lomustine, megestrol acetate, melphalan, methotrexate, 6-mercaptopurine, mitomycin-C, mitoxantrone, nilotinib, nilutamide, oxaliplatin, paclitaxel, panitumumab, pazopanib, pegasparginase, pemetrexed, procarbazine, raloxifene, rituximab, sorafenib, sunitinib, sylatron (Peg), tamoxifen, temozolomide, temsirolimus, thalidomide, thioguanine, thiotepa, topotecan, toremifene, tositumomab, trastuzumab, vemurafenib, vincristine, vinorelbine, vismodegib, vorinostat, or a mixture thereof.
