| Outline of Final Research Achievements |
Although endocrine therapy is the mainstay of treatment for advanced prostate cancer, most patients with prostate cancer progress from androgen-dependent to castration-resistant (CRPC) disease. Androgen receptor (AR) is required for CRPC progression, but AR inhibitors are antagonists only.
We discovered androprostamine (APA) , a novel inhibitor of androgen-dependent human prostate cancer cell growth, from microbial metabolite. APA showed better antitumor activity than clinically used bicalutamide in in vivo experiments using mice, but side effects such as weight loss were observed. Therefore, we synthesized 50 kinds of derivatives based on APA and succeeded in synthesis of new derivatives which keep antitumor activity with reduced side effects.
