Discovery of 7-Methoxy-6-[4-(4-Methyl-1,3-Thiazol-2-yl)-1H-Imidazol-5-yl]-1,3-Benzothiazole (TASP0382088): A Potent and Selective Transforming Growth Factor-β Type I Receptor Inhibitor as a Topical Drug for Alopecia

The conversation discusses GT20029, a drug in Phase II trials that targets androgen receptors with minimal systemic effects, and TDM-105795, a growth stimulant with a different mechanism than minoxidil that may revive papilla stem cells. Both are potential new treatments for hair loss.

The GT20029 tincture, a topical androgen receptor degrader, showed significant hair growth and good safety in a China Phase II trial for male androgenetic alopecia (AGA), with the 1% dose twice weekly identified as optimal. The company plans to initiate Phase III trials in China and Phase II in the U.S., and the treatment also shows promise for acne.

TDM-105795 is a potential hair growth stimulant that works differently from minoxidil and could be used alongside it for enhanced growth. It completed phase 2 trials in 2024, with a medium to high chance of release in 2026, but lacks recent updates or phase 3 trial information.

A user applied the 8T3 product for hair loss, targeting LPP and AGA, and plans to update on its effectiveness. The product uses a saline buffered phosphate vehicle, suitable for those intolerant to ethanolic vehicles.

The conversation discusses potential hair loss treatments focusing on stimulating IGF-1 at the follicle level using growth-factor cocktails and engineered peptides, such as Acetyl Tetrapeptide-3, Copper Tripeptide-1, Oligopeptide-20, Thymosin-β4, and Palmitoyl Tetrapeptide-7. It suggests that device-assisted delivery methods like microneedling may enhance effectiveness.

A peptide from Japanese water chestnut fruit may help with hair loss by suppressing DHT's effect on hair follicle cell death, potentially serving as a finasteride alternative. The treatment's effectiveness and safety in humans remain uncertain.
