Mecanismo de acción (Mechanism of Action)

Targets/IC₅₀/Ki	5-α reductase 10.2 nM(Ki)
In vitro	Finasteride binds to the type 2 isozyme-NADPH complex to form a ternary complex with Ki of 1.19 nM, which then rearranges to a high affinity complex (E:I) with a pseudo first order rate constant of 1.62 ms. This compound dose-dependently inhibits the growth rate of the LnCap cell line. It markedly inhibits prostate-specific antigen (PSA) secretion and expression in LNCaP cells.
In vivo	Finasteride induces dosage-related incidences of hypospadias (penischisis) in male offspring with a threshold dosage level near 0.1 mg/kg/day and a 100% effect level of 100 mg/kg/day in male rats. This compound also causes decreased anogenital distance in male offspring in male rats. This chemical and castration decreases prostate weight at day 21 by 65% and 93%, respectively, in rats. It has no significant effect on DNA content after 4 days and decreases DNA content by a maximum of 52% at 14 days in rats. It causes a less intense increase in staining in which 16% of epithelial cells stained for tissue transglutaminase on day 9 with a return to baseline by day 14 in rats. This compound-induced staining is less intense with peak staining at day 4 (0.7% of epithelial cells) and a return to control values by day 9 in rats.
