BindingDB Entry 50021519: Discovery of (2S)-N-(6-Cyano-5-(trifluoromethyl)pyridin-3-yl)-3-(6-(4-cyanophenyl)-3,6-diazabicyclo[3.1.1]heptan-3-yl)-2-hydroxy-2-methylpropanamide as a Highly Potent and Selective Topical Androgen Receptor Antagonist for Androgenetic Alopecia Treatment.

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.

The conversation discusses topical androgen receptor blockers for hair loss, mentioning Clascoterone, Pyrilutamide, GT20029, and RU58841. Ketoconazole's effectiveness and application methods are also debated.

AH-001 is a new topical treatment designed to degrade androgen receptors, targeting the root cause of androgenetic alopecia without the side effects of oral treatments like finasteride. It has shown a strong safety profile and good local tolerability in early trials.

CB-03-01 is a topical anti-androgen with low absorption, offering potential as a side-effect-free alternative to Finasteride/Dutasteride for hair loss. It's in stage 2 clinical trials for acne and showing promise for male pattern baldness.

The conversation discusses the effectiveness of anti-androgens for hair loss, with a preference for topical treatments like RU58841 over oral options due to better scalp concentration and fewer side effects. Topical finasteride at 0.1% may provide some results, especially when combined with a topical androgen receptor antagonist like RU58841.

The conversation is about choosing a topical antiandrogen for hair loss, with options including RU58841, CB0301, Pyrolutamide, Alfatradiol, and Fluridil. Users discuss their preferences and reasons for selecting specific treatments.
