Cyanonilutamide (developmental code name RU-56279) is a nonsteroidal antiandrogen which was never marketed. Both RU-56187 and RU-58841 appear to be prodrugs of cyanonilutamide in vivo in animals. It has relatively low affinity for the androgen receptor but nonetheless shows significant antiandrogenic activity in animals.
