Cloning, Expression, and Characterization of Rhesus Macaque Types 1 and 2 5alpha-Reductase: Evidence for Mechanism-Based Inhibition by Finasteride

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.

The user has been using minoxidil for hair loss and is considering trying a compounded topical treatment with 0.1% dutasteride, minoxidil, tretinoin, collagen, and silicon, as recommended by a trichologist. They learned that dutasteride might be more effective than finasteride and are seeking opinions on the use of topical dutasteride.

The conversation discusses the conflicting information about Zinc's effect on DHT and its role in hair loss. It mentions that Zinc can act as a 5AR inhibitor at high doses but may increase DHT if taken to correct a deficiency, and highlights the importance of nutritional balance for hair health.

Hair regrowth treatment involving 3aHSD enzyme shows 6% improvement in 18 weeks. Sulforaphane, L-Menthol, and Dexpanthenol are potential ingredients for new hair loss solution.

Pumpkin Seed Oil and Perilla Oil (with alpha-lipoic acid, linoleic acid, and oleic acid) are discussed as potential 5alpha-reductase inhibitors. The conversation focuses on their effectiveness for hair loss treatment.

Finasteride and dutasteride can improve skin texture and reduce acne by lowering DHT but do not reverse aging. They may enhance skin and hair health for some, but can also cause side effects like dry skin and sexual dysfunction.
