    GlossaryPhosphodiesterase

    enzyme that breaks down cyclic nucleotides in cells

    Phosphodiesterase (PDE) is an enzyme that plays a crucial role in cellular signaling by breaking down cyclic nucleotides like cAMP and cGMP, which are molecules that transmit signals inside cells. By regulating the levels of these cyclic nucleotides, PDEs help control various physiological processes, including heart rate, inflammation, and even hair growth.

      community Does caffeine inhibit 5-α-reductase?

      in Treatment  4 upvotes 6 years ago
      Caffeine may promote hair growth and potentially inhibit 5-α-reductase activity in hair follicles, but its effectiveness and systemic impact remain unclear. Users discuss using topical caffeine solutions, with some experiencing no side effects compared to finasteride.

      community Could creatine trigger faster hairloss?

      in Research/Science  28 upvotes 1 year ago

      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 New Hair Loss Cure: AMP-303 Is Back. It’s what PP405 should have been.

      in Research/Science  1 upvotes 2 weeks ago
      AMP-303 and AMP-601 are new hair loss treatments targeting dermal papilla cells, with AMP-303 showing early efficacy in transitioning vellus hairs to terminal hairs after one injection. Further clinical trials are planned, and these treatments are seen as promising due to their biologic approach and less frequent application compared to daily treatments.

      community PP405 Identity Research

      in Research  292 upvotes 7 months ago
      PP405 is a potential hair loss treatment that inhibits mitochondrial pyruvate carriers, increasing lactate dehydrogenase activity and stimulating hair follicle stem cells. In a phase 1 trial, 31% of participants showed over 20% hair density increase with PP405 treatment.

      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.
