RU-56187 is a nonsteroidal antiandrogen which was never marketed.^[1]^[2]^[3]^[4]^[5] It shows 92% of the affinity of testosterone for the androgen receptor and negligible affinity for other steroid hormone receptors.^[1]^[2] The medication is a silent antagonist of the androgen receptor.^[5] RU-56187 is 3- to 10-fold more potent as an antiandrogen than bicalutamide or nilutamide in animals.^[1] Both RU-56187 and RU-58841 appear to be prodrugs of cyanonilutamide (RU-56279) in vivo in animals.^[3]
