Thyroid receptor β: A promising target for developing novel anti-androgenetic alopecia drugs

[Display omitted] •The anti-AGA mechanism of the novel target TRβ was analyzed.•TRβ agonists with verified anti-AGA efficacy were reviewed.•The research advances in TRβ agonists with anti-AGA potential were summarized.•The SARs of TRβ agonists were comprehensively discussed. Androgenetic alopecia (AGA) significantly impacts the self-confidence and mental well-being of people. Recent research has revealed that thyroid receptor β (TRβ) agonists can activate hair follicles and effectively stimulate hair growth. This review aims to comprehensively elucidate the specific mechanism of action of TRβ in treating AGA from various perspectives, highlighting its potential as a drug target for combating AGA. Moreover, this review provides a thorough summary of the research advances in TRβ agonist candidates with anti-AGA efficacy and outlines the structure–activity relationships (SARs) of TRβ agonists. We hope that this review will provide practical information for the development of effective anti-alopecia drugs.
