ML252 hydrochloride
ML252 hydrochloride is a selective inhibitor of KCNQ2 (Kv7.2) channel with IC50s of 69 nM, 2.92 μM, 0.12 μM and 0.20 μM for KCNQ2, KCNQ1 (Kv7.1), KCNQ2/Q3 and KCNQ4, respectively. ML252 hydrochloride also inhibits Cytochrome P450 with IC50s of 6.1 nM (CYP1A2), 18.9 nM (CYP2C9), 3.9 nM (CYP3A4), 19.9 nM (CYP2D6), respectively. ML252 hydrochloride shows highly brain penetrant.

ML252 (1 μM; 0-48 h) hydrochloride shows an intrinsic clearance and subsequent predicted hepativ clearance of 1720 mL/min/kd and 67.3 mL/min/kg, respectively, in rat hepatic microsomes[1].
ML252 (0.1-10 μM) hydrochloride inhibits the current of KCNQ2 at 0.3 μM, and completely inhibits the current at 1 μM in CHO-KCNQ2 cell line[1].
ML252 (30 μM; 48 h) hydrochloride has no acute toxicity to CHO cells[1].
