A (selective) androgen receptor degrader or downregulator (SARD) is a type of drug which interacts with the androgen receptor (AR) such that it causes the AR to be degraded and thus downregulated.[1] They are under investigation for the treatment of prostate cancer and other androgen-dependent conditions.
As of 2017, dimethylcurcumin (ASC-J9), a SARD, is under development for the treatment of acne vulgaris.[2]
