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 3β-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-3β-ol or analogs thereof with tributylstannyl diazines. The compounds are potent inhibitors of human CYP 17 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.

Prodrugs of steroidal C-17 benzoazoles, pyrimidinoazoles(azabenzoazoles) and diazines. Methods of synthesis are also described, whereby a prodrug group is substituted for a functional group at A ring portion of the ABC ring structure of the steroid. Suitable prodrug groups include amino acid groups, succinate groups, phosphate groups, or sulfamate groups. The prodrugs of the disclosed compounds allow for improved oral bioavailability of the compounds that are inhibitors of human CYP17 enzyme as well as potent antagonists of both wild type and mutant androgen receptors (AR). The compounds and the corresponding prodrugs are useful for the treatment of conditions such as human prostate cancer, breast cancer, and prostate hyperplasia.
