TLDR Scientists made new substances that can block an enzyme linked to prostate issues and hair loss, with potential for creating a new treatment.

In 2003, researchers synthesized and evaluated novel inhibitors of human 5α reductase, an enzyme linked to conditions like benign prostatic hyperplasia and androgenic alopecia (hair loss). The study focused on compounds known as 4-(2-phenylethyl)cyclohex-1-ene carboxylic acids 1-5. These compounds were found to be effective inhibitors of the prostatic isozyme 2, with compound 1 being the most potent (IC50 = 760 nM). However, they only slightly inhibited isozyme 1. The researchers concluded that these compounds could be further optimized for the development of a new drug for the treatment of benign prostatic hyperplasia and potentially hair loss conditions.

Most hair loss treatments are ineffective; only finasteride, dutasteride, and minoxidil show effectiveness.

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.

community Dutasteride SAVES your hair follicles: MAJOR BS on people who say it destroyed their hair permanently.

in Finasteride/Dutasteride 156 upvotes 11 months ago

The conversation discusses the effectiveness of hair loss treatments, specifically finasteride and dutasteride. The conclusion is that dutasteride significantly reduces DHT levels and may be more effective than finasteride for long-term hair retention, with some users reporting personal experiences and side effects.
