Discovery of an Androgen Receptor Degrader Featuring a Pyridazinyl Glutarimide CRBN-Binding Motif for Transdermal Treatment of Androgenetic Alopecia

In this study, researchers discovered a compound called C6 that exhibits excellent skin retention and androgen receptor degradation properties, significantly promoting hair regeneration in a mouse model of androgenetic alopecia following non-invasive topical application, suggesting potential for broader use of PROTACs in treating skin diseases.

This study developed a method for designing peptide-based PROTAC drugs using advanced AI models, successfully identifying peptides that bind to specific receptors and incorporating them into a potential transdermal treatment for androgenetic alopecia.

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.

In this study, miR-221 was identified as a key factor in androgenetic alopecia pathogenesis due to its role in suppressing hair growth by interacting with androgen receptors and affecting related pathways.

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.

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.

This study reported that oral minoxidil was associated with clinical improvement in androgenetic alopecia and telogen effluvium, showing better outcomes compared to controls.

This review highlights bicalutamide as a promising oral therapy for female pattern hair loss, noting its safety, tolerability, and effectiveness in women with hyperandrogenic symptoms like acne and hirsutism, though further trials are needed to confirm its ideal dose and efficacy.

This review discusses the progress in research on topical formulations for treating alopecia, highlighting potential advantages of advanced formulation technologies but reporting no new clinical results.

This review discusses the potential of stem cell-based therapies, particularly involving stem cell-derived conditioned medium and exosomes, for hair regeneration in nonscarring alopecia, but it reports no new clinical outcomes.

This review article provides an updated overview of the pharmacology, mechanism of action, clinical efficacy, and adverse events associated with topical minoxidil, a widely used treatment for androgenetic alopecia and other hair loss conditions, while noting that its exact mechanism is still not fully understood.

This review describes the molecular interactions between androgens and Wnt/ß-catenin signaling in androgenetic alopecia but reports no new experimental or clinical findings; the authors discuss potential Wnt/ß-catenin-targeted treatments for hair growth.

This review explores the relationship between androgenetic alopecia and metabolic syndrome, suggesting an association that supports considering cardiovascular risk assessments in patients with this type of hair loss.

This review compares animal and human skin characteristics in in vitro permeation studies but reports no new results, highlighting variations and the need for better model correlations.

This systematic review and meta-analysis found that minoxidil, finasteride, and low-level laser light therapy significantly improve hair growth in men with androgenetic alopecia, while minoxidil is also effective for women, compared to placebo.

This study found that increased expression of type II 5α-reductase, androgen receptors, and Hic-5/ARA55 in dermal papilla cells upregulates androgen sensitivity, playing a key role in androgenetic alopecia pathogenesis.

This review discusses common hair loss conditions and explores how advancements in hair follicle biology might lead to more effective treatments but reports no new results.

People with hair loss have more androgen receptors and enzymes in certain follicles, with men and women showing different patterns.
