    TLDR The new progesterone derivatives effectively inhibit 5α-reductase and bind to the androgen receptor.
    The study evaluated the in vitro inhibitory activity of five new progesterone derivatives on the 5α-reductase enzyme and their antagonistic effects on the androgen receptor. The compounds showed varying IC50 values for 5α-reductase inhibition, with compound 3 being the most potent (19 nM). The Ki values indicated that compound 4 had the highest affinity for the androgen receptor, followed by compound 5, dihydrotestosterone, compound 2, compound 3, and compound 1. Overall, all five synthesized compounds were effective 5α-reductase inhibitors and exhibited affinity for the androgen receptor in the hamster prostate.

      The conversation discusses whether finasteride's reduction of DHT and increase in scalp testosterone contribute to hair follicle miniaturization. Some participants argue testosterone does not cause miniaturization, while others suggest that even with reduced DHT, other androgens like testosterone may still contribute to hair loss.
