Isolation and HPLC Quantitative Determination of 5α-Reductase Inhibitors from Tectona Grandis Leaf Extract

Teak leaf extract shows potential as a mild hair growth promoter for androgenic alopecia, with similar positive trends to minoxidil but without significant side effects. It can be made at home using dried teak leaves and ethanol, though its effectiveness compared to other treatments like finasteride is debated.

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 the molecular structures of compounds that reduce DHT levels, including finasteride and Ashwagandha. It explores the potential of using Ashwagandha topically as a 5a reductase inhibitor.

Natural vitamins like pumpkin seed oil, saw palmetto, and ecklonia cava are discussed for their potential to lower DHT levels. They may work similarly to finasteride but are significantly weaker.

He Shou Wu (Fo Ti) extract was found to prolong the hair growth phase, inhibit 5-alpha-reductase (like finasteride), reduce androgen receptors, and increase growth factors, potentially outperforming minoxidil in recovering hair follicle size after DHT exposure. Two compounds, emodin and TSG, are identified as responsible for these effects and warrant further investigation.

Natural alternatives like omega-3, green tea, and pumpkin seeds are suggested for reducing DHT levels, but their effectiveness is questioned. Topical minoxidil and ketoconazole shampoo are recommended, with some users also considering low-dose finasteride and saw palmetto.
