KSC-12-192 is a drug that is used in scientific research to study the κ-opioid receptor, where it acts as a biased agonist.^[1]

KSC-12-192 preferentially activates G-protein coupling over β-arrestin 2 recruitment in vitro, an intrinsic activity shared with many other KOR ligands developed to separate KOR-mediated analgesia from accompanying dysphoria.

Compared with most of the known KOR G-protein biased agonists, KSC-12-192 and its parent compound ML138 do not exhibit stereoisomerism.

Out of a range of tested compounds with the same substituted triazole scaffold (see table), KSC-12-192 had the highest reported in vitro potency as a human KOR agonist (EC₅₀ = 31nM^[2]).
