SKF-83,959 is a synthetic benzazepine derivative used in scientific research which acts as an agonist at the D1–D2 dopamine receptor heteromer.[1] It behaves as a full agonist at the D1 protomer and a high-affinity partial agonist at the D2 protomer. It was further shown to act as an allosteric modulator of the sigma-1 receptor.[2] SKF-83,959 additionally inhibits sodium channels[3] as well as delayed rectifier potassium channels.[4] SKF-83,959 is a racemate that consists of the R-(+)- and S-(−)-enantiomers MCL-202 and MCL-201, respectively.
