ML-193 (0.01-100 μM; pretreated for 15 min) inhibits β-arrestin trafficking induced by L-α-lysophophosphatidylinositol (LPI, 10 μM) and ML186 (1 μM) with IC50s of 0.22 μM and 0.12 μM, respectively.
ML-193 (0.01-10 μM; pretreated for 30 min) decreases the LPI-mediated ERK1/2 phosphorylation, with an IC50 of 0.2 μM in U2OS cells.
ML-193 (5 μM; pretreated for 30 min) attenuates the GPR55 agonists induced increases in hNSCs proliferation rates.
ML-193 (5 μM; 10 d) attenuates the ML184-induced increases in hNSCs differentiation.
