Finasteride-d9 is intended for use as an internal standard for the quantification of finasteride by GC- or LC-MS. Finasteride is a 4-azasteroid competitive inhibitor of 5α-reductase type II (IC50 = 4.2 nM) and a derivative of testosterone.1 It is 100-fold selective for 5α-reductase type II over type I. Finasteride (10 µM) does not affect the growth of androgen-refractory PC3 prostate cancer cells but increases the protein levels of Nrf2 and heme oxygenase-1 (HO-1).2 It decreases prostatic diameter and volume, as well as dihydrotestosterone, but not testosterone, serum levels in dogs with spontaneous benign prostatic hypertrophy when administered at doses of 0.1 and 0.5 mg/kg.3 Finasteride reduces testosterone-induced type I procollagen and TGF-β1 protein levels in cultured human scalp dermal fibroblasts in a model of androgenic alopecia when applied at a concentration of 0.1 μM.4 Formulations containing finasteride have been used in the treatment of benign prostatic hyperplasia and androgenic alopecia in men.
