ML192 is a selective ligand antagonist of GPR55 . ML192 inhibits the β-arrestin trafficking, ERK1/2 phosphorylation and PKCβII translocation In Vitro ML192 inhibits the β-arrestin trafficking induced by 10 μM L-α lysophosphatidylinositol (LPI) or 1 μM ML186 with IC 50 values of 0.70 µM and 0.29 µM, respectively. ML192 significantly inhibits ERK1/2 phosphorylation in GPRSS-expressing U2OS cells with an IC 50 value of 1.1 µM. ML192 (0, 10, 30 and 100 µM) reduces the translocation of PKCβII in cells with the Wild-Type GPR55 receptor. MCE has not independently confirmed the accuracy of these methods. They are for reference only. Form:Solid IC50& Target:ERK2 ERK1 PKCβII
