Patent Claims:	1. A method of treating prostate cancer in a subject, comprising administering to the subject a therapeutically effective amount of 5-fluoro-8-(4-fluorophenyl)-9-(1-methyl-1H-1,2,4-triazol-5-yl)-8,9-dihydro-2H-pyrido[4,3,2-de]phthalazin-3(7H)-one, or a pharmaceutically acceptable salt or solvate thereof. 2. The method of claim 1, wherein said administration is in combination with ionizing radiation, one or more chemotherapeutic agents, or a combination thereof. 3. The method of claim 2, wherein the compound is used in combination with one or more chemotherapeutic agents, wherein each chemotherapeutic agent is independently methyl methanesulfonate, temozolomide, dacarbazine (DTIC), a topoisomerase-1 inhibitor, Topotecan, Irinotecan, Rubitecan, Exatecan, Lurtotecan, Gimetecan, Diflomotecan, a homocamptothecin, Doxorubicin, a platinum based antineoplastic agent, a 7-substituted non-silatecan, a 7-silyl camptothecin, paclitaxel, cetuximab, daunorubicin, methotrexate, a hormone, an antiestrogen, an antiandrogen, a gonadotropin releasing hormone analog, an interferon, alpha interferon, a tyrosine kinase inhibitor, gefitinib, imatinib, gemtuzumab, or BNP 1350. 4. The method of claim 2, wherein the compound is used in combination with one or more chemotherapeutic agents, wherein each chemotherapeutic agent is independently irinotecan, cisplatin, carboplatin, paclitaxel, or temozolomide. 5. The method of claim 1, wherein the subject is a human. 6. The method of claim 2, wherein the subject is a human. 7. The method of claim 3, wherein the subject is a human. 8. The method of claim 4, wherein the subject is a human. 9. A method of treating prostate cancer in a subject, comprising administering to the subject a therapeutically effective amount of (8S,9R)-5-fluoro-8-(4-fluorophenyl)-9-(1-methyl-1H-1,2,4-triazol-5-yl)-8,9-dihydro-2H-pyrido[4,3,2-de]phthalazin-3(7H)-one, or a pharmaceutically acceptable salt. 10. The method of claim 9, wherein said administration is in combination with ionizing radiation, one or more chemotherapeutic agents, or a combination thereof. 11. The method of claim 10, wherein the compound is used in combination with one or more chemotherapeutic agents, wherein each chemotherapeutic agent is independently methyl methanesulfonate, temozolomide, dacarbazine (DTIC), a topoisomerase-1 inhibitor, Topotecan, Irinotecan, Rubitecan, Exatecan, Lurtotecan, Gimetecan, Diflomotecan, a homocamptothecin, Doxorubicin, a platinum based antineoplastic agent, a 7-substituted non-silatecan, a 7-silyl camptothecin, paclitaxel, cetuximab, daunorubicin, methotrexate, a hormone, an antiestrogen, an antiandrogen, a gonadotropin releasing hormone analog, an interferon, alpha interferon, a tyrosine kinase inhibitor, gefitinib, imatinib, gemtuzumab, or BNP 1350. 12. The method of claim 10, wherein the compound is used in combination with one or more chemotherapeutic agents, wherein each chemotherapeutic agent is independently irinotecan, cisplatin, carboplatin, paclitaxel, or temozolomide. 13. The method of claim 10, wherein the subject is a human. 14. The method of claim 10, wherein the subject is a human. 15. The method of claim 11, wherein the subject is a human. 16. The method of claim 12, wherein the subject is a human.
