What is RU58841?
RU58841 is a non-steroidal AR antagonist designed for topical application — high local AR blockade in scalp tissue with rapid systemic clearance minimising systemic androgenic effects. Research tool for scalp androgen receptor antagonism, androgenetic alopecia models, and topical AR blocker pharmacology. Research use only.
Research Applications
Topical AR Antagonism
Scalp dermal AR blockade — competitive inhibition of DHT at follicle
Androgenetic Alopecia
Hair follicle DHT signalling blockade, follicle miniaturisation prevention
Local vs Systemic AR Blocking
RU58841 rapid hydrolysis — topical efficacy without systemic AR antagonism
Dermal Papilla Research
AR-mediated papilla cell apoptosis inhibition, androgen-responsive gene blockade
Comparative Topical AR Blocker
RU58841 vs finasteride — AR antagonism vs 5α-R inhibition in follicle models
