| | ML-252 (hydrochloride) Usage And Synthesis |
| Uses | 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[1][2]. | | in vivo | ML252 (10 mg/kg, 3 mg/mL; ip; single dose; measured at 1 hr after) hydrochloride shows a highly brain penetrant with a B:P ratio of 1.9 and absolute brain levels of 672 nM in rat model[1].
ML252 hydrochloride has the metabolic stability unsuitable for oral administration[2].
