ML-193

ML-193 is a potent antagonist of GPR55 (IC50 = 221 nM). It displays selectivity for GPR55 over CB1, CB2, and GPR35. ML-193 inhibits GPR55-dependent ERK phosphorylation (IC50 = 65 nM) and blocks translocation of PKCbetaII. ML-193 blocks increases in intracellular calcium levels induced by lysophosphatidylinositol (LPI) in dissociated rat periaqueductal gray neurons and modulates pain perception in LPI-treated rats.Formal Name: N-[4-[[(3,4-dimethyl-5-isoxazolyl)amino]sulfonyl]phenyl]-6,8-dimethyl-2-(2-pyridinyl)-4-quinolinecarboxamide.
