June 2024 in “Journal of medicinal chemistry” A new AI-driven method shows promise for treating hair loss with a peptide-based drug.
November 2025 in “Journal of Medicinal Chemistry” Proteolysis-targeting chimeras (PROTACs) are being explored for topical use to achieve localized protein degradation with reduced systemic toxicity. This article discusses advances in topical PROTACs, highlighting androgen receptor degraders AH-001 and GT20029, which are in clinical trials for androgenetic alopecia, with GT20029 also being tested for acne. The scope of PROTACs is expanding to target proteins like JAK kinases and BET family members, with potential applications in dermatology, pulmonary and ocular diseases, and cosmetics. Innovative delivery methods, such as liposomes and microneedle systems, are enhancing local delivery. However, challenges remain in optimizing stability, tissue penetration, and target engagement. The article suggests strategic directions to advance the clinical application of topical PROTACs.
December 2022 in “Small methods” A new hair loss treatment using dissolving microneedles was found to speed up hair growth and was more effective than daily use of common hair growth drugs.
December 2024 in “Journal of Medicinal Chemistry” A new topical treatment for hair loss shows promise by targeting androgen receptors.
