Description: Clascoterone, also known as CB-03-01 and cortexolone 17alpha-propionate, is a topical and peripherally selective and potent androgen antagonist for topical treatment of acne vulgaris. Clascoterone is a steroidal antiandrogen, or antagonist of the androgen receptor (AR), the biological target of androgens such as testosterone and dihydrotestosterone (DHT). In a bioassay, the topical potency of the medication was greater than that of progesterone, flutamide, and finasteride and was equivalent to that of cyproterone acetate. Likewise, it is significantly more efficacious as an antiandrogen than other AR antagonists such as enzalutamide and spironolactone in scalp dermal papilla cells and sebocytes in vitro.
