    laboratory devices measuring substance diffusion through barriers

    Franz diffusion cells are laboratory devices used to study the rate at which substances, such as drugs or cosmetic ingredients, pass through a barrier, typically skin or a synthetic membrane. They consist of two chambers separated by the barrier: one chamber holds the test substance, while the other contains a fluid that collects the diffused substance, allowing researchers to measure how quickly and effectively the substance penetrates the barrier.

      FCE 28260: A Forgotten 5α-Reductase Inhibitor

      community FCE 28260: A Forgotten 5α-Reductase Inhibitor

      in Research  330 upvotes 2 months 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.
