Glossary5-alpha-reductase inhibitor

blocks enzyme converting testosterone to dihydrotestosterone (DHT)

A 5-alpha-reductase inhibitor is a type of medication that blocks the enzyme 5-alpha-reductase, which is responsible for converting testosterone into dihydrotestosterone (DHT). By reducing DHT levels, these inhibitors can help treat conditions like male pattern baldness and benign prostatic hyperplasia (BPH).

community FCE 28260: A Forgotten 5α-Reductase Inhibitor

in Research 330 upvotes 1 year ago

FCE 28260 (PNU 156765), an under-explored 5α-reductase inhibitor, showcases promising results in research by Giudici et al., outperforming well-known treatments like Finasteride in reducing the conversion of testosterone to DHT. Its superior efficacy, demonstrated through lower IC50 values in both natural and human recombinant enzyme studies, suggests it could offer more effective management of DHT-related conditions. Additionally, its lower molecular weight hints at better potential for topical application, potentially offering advantages in treating conditions such as androgenic alopecia. Despite its potential, it has not advanced in development, possibly due to financial limitations, leaving its therapeutic prospects and side effect profile largely unexplored.
