What is Finasteride?
Finasteride is a competitive 5α-reductase Type II inhibitor — blocks testosterone conversion to dihydrotestosterone (DHT). Reduces serum DHT by ~70%. Research: androgen metabolism, DHT-mediated BPH, androgenetic alopecia, DHT vs testosterone tissue-specific activity, 5α-reductase enzyme biology. CAS 98319-26-7.
Research Applications
5α-Reductase Inhibition
T→DHT conversion block — DHT-mediated androgenic pathway research
BPH/Prostate Models
DHT reduction in prostate — stromal and epithelial androgen research
Androgenetic Alopecia
