Delanterone (INN) (developmental code name GBR-21162), also known as 1α-methylandrosta-4,16-dien-3-one, is a steroidal antiandrogen described as an anti-acne agent which was never marketed. The compound showed poor efficacy as an antiandrogen in vivo in animals, suggestive of low activity or a short half-life, and likely in relation to this was not further developed. It was characterized and reported on in 1977.
