  • Publication number: 20190169227
    Abstract: Galeterone and its C-3 analogs are of substantial interest because of their multi-target anticancer activities, including AR and Mnk degrading activities. Provided are novel procedures for gram-scale, high-yield synthesis of C-3 analogs of galeterone, including 3?-(1H-imidazole-1-yl)-17-(1H-benzimidazole-1-yl)-androsta-5,16-diene (galeterone 3?-imidazole) and 3?-(pyridine-4-ylmethoxy)-17-(1H-benzimidazol-1-yl)androsta-5,16-diene (galeterone 3?-pyridine methoxylate).

  • Patent number: 7960435
    Abstract: A qualitative 3D pharmacophore model (a common feature based model or Catalyst HipHop algorithm) developed from well-known natural product androgen receptor down-regulating agents (ARDAs). The 3D pharmacophore model is used as a template in virtual screening compounds for new ARDAs. ARDA compounds and compounds that strongly inhibit the growth of human prostate LNCaP cells. The compounds may be used in compositions and methods of inhibiting cell proliferation of a cancer and methods of preventing or treating cancer, including prostate cancer.
