Testifenon

Testifenon, also known as testiphenon, testiphenone, chlorphenacyl dihydrotestosterone ester, or dihydrotestosterone 17β-(4-(bis(2-chloroethyl)amino)phenyl)acetate, is a synthetic anabolic–androgenic steroid (AAS) and a cytostatic antineoplastic agent (i.e., chemotherapeutic) that was never marketed.[1][2][3] It is an androgen ester – specifically, a chlorphenacyl nitrogen mustard ester of dihydrotestosterone (DHT) – and acts as a prodrug of these two components in the body.[1][2] The drug was developed in Russia as a tissue-selective cytostatic drug for the treatment of various cancers occurring in androgen receptor-expressing tissues that would have reduced side effects and toxicity relative to other chemotherapy drugs.[1][2]
