Pricing Availability Delivery Time Qty
Cat.No. 5842 - MK 386 | C28H49NO | CAS No. 158493-17-5
Description: Potent, selective human type 1 5α-reductase inhibitor
Chemical Name: (4aR,4bS,6aR,7R,9aS,9bS,10S,11aR)-7-[(1R)-1,5-Dimethylhexyl]hexadecahydro-1,4a,6a,10-tetramethyl-2H-indeno[5,4-f]quinolin-2-one
Purity: ≥98% (HPLC)

Biological Activity

Potent and selective human type 1 5α-reductase inhibitor (5αR1, IC50 = 0.9 nM). Exhibits 100-fold selectivity for 5αR1 over 5αR2 (IC50 = 154 nM). Supresses human serum and sebum dihydrotestosterone (DHT) levels in a dose-dependent manner without affecting semen DHT concentrations. Orally active.
