De Novo-Designed Bifunctional Proteins for Targeted Protein Degradation

AH-001 is a new topical treatment designed to degrade androgen receptors, targeting the root cause of androgenetic alopecia without the side effects of oral treatments like finasteride. It has shown a strong safety profile and good local tolerability in early trials.

A peptide-based delivery system for finasteride shows promise in reducing systemic side effects while maintaining hair growth effectiveness. Combining this with other treatments like minoxidil and RU58841 could enhance results with lower systemic absorption.

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.

PP405 is a potential hair loss treatment that may activate dormant hair follicles, but there are concerns about its effectiveness, cost, and side effects. Users discuss treatments like minoxidil, finasteride, and RU58841, expressing skepticism about PP405's long-term success and accessibility.

The conversation is about the use of peptide therapies for hair loss, specifically GHK-CU, ZN-Thymulin, and PTD-DBM. The user is seeking feedback on the effectiveness of these treatments from those who have tried them.

PTD-DBM therapy for hair loss is being developed by Dr. Kang-Yell Choi, with human testing planned in South Korea. Some clinics in the U.S. offer PTD-DBM/valproic acid therapy, but it hasn't completed trials yet.
