RU-58841, also known as PSK-3841 or HMR-3841, is a nonsteroidal antiandrogen (NSAA) which was initially developed in the 1980s. It was formerly under investigation by ProStrakan (previously ProSkelia and Strakan) for potential use as a topical treatment for androgen-dependent conditions including acne, pattern hair loss,[1] and excessive hair growth.[2][3][4][5] The compound is similar in structure to the NSAA RU-58642 but contains a different side-chain.[6] These compounds are similar in chemical structure to nilutamide,[7] which is related to flutamide, bicalutamide, and enzalutamide, all of which are NSAAs similarly.[8] RU-58841 can be synthesized either by building the hydantoin moiety or by aryl coupling to 5,5-dimethylhydantoin.[9]
RU-58841 produces cyanonilutamide (RU-56279) and RU-59416 as metabolites in animals.[10] Cyanonilutamide has relatively low affinity for the androgen receptor but shows significant antiandrogenic activity in animals.[10] RU-59416 has very low affinity for the androgen receptor.[10]
