Abstract
In our effort to discover potent and specific inhibitors of 17α-hydroxylase/17,20-lyase (CYP17), the key enzyme which catalyzes the biosynthesis of androgens from progestins, 3β-(hydroxy)-17-(1H-benzimidazole-1-yl)androsta-5,16-diene (Galeterone or TOK-001, formerly called VN/124-1) was identified as a selective development candidate which modulates multiple targets in the androgen receptor (AR) signaling pathway. This drug annotation summarizes the mechanisms of action, scientific rationale, medicinal chemistry, pharmacokinetic properties, and human efficacy data for galeterone, which has successfully completed phase II clinical development in men with castration resistant (advanced) prostate cancer (CRPC). Phase III clinical studies in CRPC patients are scheduled to begin in early 2015.
