SKF-83,959

SKF-83,959, a synthetic benzazepine derivative used in scientific research, 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.
