Steroidogenesis Inhibitors Alter But Do Not Eliminate Androgen Synthesis Mechanisms During Progression to Castration-Resistance in LNCaP Prostate Xenografts

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.

RU58841, an anti-androgenic compound, showed early promise for treating alopecia but faced challenges after its patent in 1997. Despite advancing to Phase II trials, safety concerns and financial struggles led Aventis to abandon its development. Proskelia, which later merged into ProStrakan, couldn't prioritize the drug, leading to its eventual stagnation and failure to reach the market.

The conversation discusses androgen receptor degraders for hair loss, highlighting their potential advantages over traditional AR blockers like RU58841 and pyrilutamide. Concerns about the safety and cost of these treatments are also mentioned.

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.

Orient Bio is developing a PLGA formulated version of Cyclosporine A to stimulate hair growth without its immunosuppressant effects. Users discuss various treatments like Clascoterone, PP405, minoxidil, and tacrolimus, expressing hope for new developments and sharing personal experiences with these treatments.

The user is using finasteride, minoxidil, and ciclopirox shampoo for hair loss and is considering adding a topical anti-androgen like RU58841, Clacosterone, or KX286. They have scheduled a hair transplant and are concerned about the cost and effectiveness of future treatments.
