RU-58642 is a non-steroidal antiandrogen with very high affinity and selectivity for the androgen receptor (AR), which made it among the most potent and efficacious antiandrogens known at the time of its discovery.[1] It was investigated for topical application for the treatment of androgenetic alopecia (male-pattern baldness), but development did not proceed past initial trial stages, and it is now only used for scientific research into the AR.[2][3]
