      FCE 28260: A Forgotten 5α-Reductase Inhibitor

      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.

      community The story of RU58841/PSK3841

      in Research/Science 1 year ago
      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.

      community Pyrilutamide ,the molecule’s true nature

      in Research  302 upvotes 1 year ago
      Pyrilutamide is a selective AR antagonist with a high binding affinity, making it effective in competing with DHT for androgen receptors. The 1% concentration is more effective than the 0.5%, but the latter may suffice for mild hair loss; the drug is considered a good option for those avoiding 5AR blockers due to side effects.

      community DLQ01: A Better "Minoxidil" PGF2a synthetic analogue.

      in Research/Science  3 upvotes 1 year ago
      DLQ01, a prostaglandin F2α analog, shows promise for hair growth by directly stimulating PGE2/PGF receptors without needing conversion, and can be combined with minoxidil and retinoids like tretinoin for enhanced effectiveness. Minoxidil's efficacy may be reduced by COX-1 inhibitors, but using prostaglandin analogs like Latanoprost or Bimatoprost can help maintain its effectiveness.

      community Is regrowth on an androgen receptor blocker possible?

      in Chat  11 upvotes 2 years ago
      RU and Pyri block androgen receptors to prevent hair loss but may also hinder hair regrowth since they prevent testosterone, which can stimulate hair growth, from binding to these receptors. The user is questioning if this understanding is correct.
