体外研究
The ratio of total concentration of extracellular ML133 versus intracellular ML133 is 1:0.13 at pH 6.5, 1:9.09 at pH 8.5. ML133 is clean against 3A4 and 2C9 (IC50 >30 μM), displays moderate inhibition of 1A2 (IC50 = 3.3 μM) but proves to be a potent inhibitor of 2D6 (IC50 = 0.13 μM) in CYP450 assay. ML133 is highly protein bound (>99%) in both human and rat and also displays high intrinsic clearance in both species. ML133 (10 μM) is not displaced by K+ influx from the wild-type Kir2.1 in HEK 293 cells. M1 and/or M2 transmembrane domains contain the critical molecular determinant for ML133 inhibition of Kir2.1, especially D172 and I176.
