December 2023 in “Journal of Medicinal Chemistry” In this study, researchers identified compound 30a as a promising topical androgen receptor antagonist that promoted hair growth in mouse models of androgenetic alopecia without noticeable toxicity, suggesting its potential for treating this hair loss condition.
This comprehensive review analyzes androgenetic alopecia treatments, discussing the mechanisms, costs, efficacy, and safety of FDA-approved drugs like minoxidil and finasteride, as well as newer non-FDA-approved options that have shown effectiveness across various studies.
December 2022 in “Small methods” This study developed dissolving microneedles incorporating a new AR degrader for treating androgenetic alopecia, showing that a single application leads to superior hair regeneration compared to daily minoxidil, without systemic toxicity or androgen-related issues.
November 2022 in “Molecular Pharmaceutics” This study found that intradermal injection of a cell-penetrating, AR-targeting asiRNA promoted hair growth and reduced androgen receptor expression in mouse models of androgenetic alopecia, suggesting its therapeutic potential.
