A prodrug that is converted in vivo into abiraterone. Used for treatment of metastatic castrate-resistant prostate cancer. It has a role as a prodrug, an antineoplastic agent and an EC 1.14.99.9 (steroid 17alpha-monooxygenase) inhibitor. It is a sterol ester and a member of pyridines. It is functionally related to an abiraterone."}]
