4-(Alkylthio)- and 4-(Arylthio)-Benzonitrile Derivatives as Androgen Receptor Antagonists for the Topical Suppression of Sebum Production

In 2009, researchers synthesized 4-(alkylthio)- and 4-(arylthio)-benzonitrile derivatives, which are androgen receptor antagonists, and tested them for their ability to reduce sebum production. The androgen receptor activates genes involved in acne and alopecia, and its antagonists can potentially suppress sebum production, associated with acne vulgaris. The compounds were tested on five male Syrian hamsters aged 9-10 weeks, twice daily for 2 weeks. The results showed a moderate reduction in sebum production, suggesting potential use for these compounds in the topical treatment of conditions like acne and alopecia.
