    block an enzyme to reduce inflammation and immune responses

    PDE4 inhibitors, also known as Phosphodiesterase 4 inhibitors or PDE4i, are a class of drugs that block the enzyme phosphodiesterase 4. This enzyme is involved in breaking down cyclic adenosine monophosphate (cAMP), a molecule that plays a crucial role in regulating inflammation and immune responses. By inhibiting PDE4, these drugs can help reduce inflammation and are used to treat conditions like psoriasis, chronic obstructive pulmonary disease (COPD), and certain types of alopecia.

      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.
