    GlossaryCCR5 antagonist

    blocks HIV entry into cells by targeting the CCR5 receptor

    A CCR5 antagonist, also known as a CCR5 inhibitor or CCR5 blocker, is a type of drug that blocks the CCR5 receptor on the surface of certain cells. This receptor is used by HIV to enter and infect human cells. By blocking CCR5, these drugs can help prevent HIV from spreading within the body, making them an important tool in the treatment of HIV/AIDS.

      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.
