  • Publication number: 20100047338
    Abstract: Described are steroidal C-17 benzoazoles, pyrimidinoazoles (azabenzoazoles) and diazines. Methods for their synthesis are also described, which include methods having a step of nucleophilic vinylic “addition-elimination” substitution reaction of 3?-acetoxy-17-chloro-16-formylandrosta-5,16-diene or analogs thereof and benzoazole or pyrimidinoazole nucleophiles and methods having a palladium catalyzed cross-coupling reaction of 17-iodoandrosta-5,16-dien-3?-ol or analogs thereof with tributylstannyl diazines. The compounds are potent inhibitors of human CYP17 enzyme as well as potent antagonists of both wild type and mutant androgen receptors (AR). The compounds are useful for the treatment of human prostate cancer.

  • Publication number: 20030096799
    Abstract: The application discloses novel 2-alkoxyestradiol analogs which exhibit anti-proliferative properties, and methods of making and using such compounds to inhibit undesired cell proliferation and tumor growth. Additionally, methods are disclosed of treating diseases associated with undesired angiogenesis and undesired proliferation, and methods of treating infectious disease wherein the infectious agent is particularly susceptible to inhibition by agents that disrupt microtubule organization and function.
