Abstract
A new topically active non-steroidal antiandrogen, RU 58841 has been synthesized. It
displays high affinity for the hamster prostate and flank organ (F.O.) androgen receptors.
In vivo, when topically applied, it exerts a potent dose-dependent regression of F.O. area
at a dose as low as 1 microgram/animal while being devoid of antiandrogenic activity on
deep accessory sex organs and of any effect on testosterone level up to 100
micrograms/animal. In the same species, after subcutaneous administration, it induces at
the dose of 300 micrograms/animal, a small decrease in F.O. area equivalent to that of 1
microgram applied topically and a weak systemic activity. In intact rats, no effects were
observed up to 1 microgram/animal whatever the route of administration. These results
suggest that RU 58841 might useful for the topical treatment of androgen-dependent skin
disorders such as acne, androgenetic alopecia and hirsutism.
