Dimethylcurcumin (development code ASC-J9) is a nonsteroidal antiandrogen and a synthetic curcuminoid which is under development by AndroScience Corporation as a topical medication for the treatment of acne vulgaris.[1][2] It has also been under investigation for the treatment of male pattern hair loss, spinal muscular atrophy, and wounds, but no development has been reported for these indications.[1] There has been interest in the drug for the potential treatment of prostate cancer as well.[2][3] As of 2017, it is in phase II clinical trials for acne vulgaris.[1]

Dimethylcurcumin is an androgen receptor (AR) inhibitor and shows strong and specific antiandrogenic activity in vitro (e.g., against LNCaP cell growth) at sufficiently high concentrations.[3] However, its mechanism of action and effects differ from those of conventional antiandrogens; it is not an antagonist of the AR and instead appears to act as a selective degradation enhancer (SARD) of certain subpopulations of the AR, for instance those present in the prostate gland.[1][3][2]
