Improved 2α-Hydroxylation Efficiency of Steroids by CYP154C2 Using Structure-Guided Rational Design

Androsterone may help with sexual and affective dysfunction from finasteride by replacing disrupted neurosteroids without increasing androgenic side effects. Controlled testing is needed to confirm its effectiveness and safety.

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 conversation discusses using cyproterone temporarily to reverse hair loss, followed by finasteride to maintain regrowth. Concerns about cyproterone's side effects, such as lowering testosterone and potential health risks, are raised, with alternatives like spironolactone suggested for androgen-related issues.

Finasteride has no effect on the user's estradiol levels, and body fat may influence aromatization. The user is on testosterone replacement therapy and uses everyday injections to manage high RBC count, with plans to measure DHT, DHEA-S, and pregnenolone levels.

The conversation discusses the hypothesis that a lack of the enzyme 3-alpha hydroxysteroid dehydrogenase (3α-HSD) on the scalp may contribute to hair loss by allowing DHT to accumulate. Despite interest in this theory, no recent research has been conducted, and current treatments like finasteride and minoxidil remain the most supported options.

The conversation discusses topical androgen receptor blockers for hair loss, mentioning Clascoterone, Pyrilutamide, GT20029, and RU58841. Ketoconazole's effectiveness and application methods are also debated.
