    GlossaryDisulfide Bonds

    strong covalent links between sulfur atoms in proteins

    Disulfide bonds, also known as S-S bonds, are strong covalent bonds formed between two sulfur atoms, typically within the amino acid cysteine. These bonds play a crucial role in stabilizing the three-dimensional structure of proteins, including keratin in hair, by linking different parts of the protein chain. In hair, disulfide bonds contribute to its strength and elasticity, and their alteration can affect hair texture and resilience.

      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.
