AA560

AA560 is an orally active nonsteroidal antiandrogen (NSAA) that was developed in Japan and was first described in the literature in 1977 but was never marketed.[1][2][3] It is an anilide derivative and analogue of the NSAA flutamide, and shows greater in vivo antiandrogenic potency than does flutamide.[1][2] Similarly to flutamide, AA560 is a selective antagonist of the androgen receptor (AR) and consequently shows progonadotropic effects by increasing levels of gonadotropins and testosterone via disinhibition of the hypothalamic-pituitary-gonadal axis.[1][2][4]
