氯美噻唑 用途与合成方法
Clomethiazole (1 mM), in the absence of GABA, to α1/β1/γ2 or α1/β2/γ2 subunit-containing cells produced large whole-cell currents. Clomethiazole activate GABAA currents in α1/β1/γ2- and α1/β2/γ2-containing cells, with EC 50 values of 0.3 and 1.5 mM, respectively. Clomethiazole (30 μM) at low concentration also potentiates the action of GABA in both cell types, equivalent to a 3-fold increase in potency and up to 1.8-fold increase in maximal current. Clomethiazole inhibits cytochrome P450 isoforms, CYP2A6 and CYP2E1 with IC 50 values of 24 µM and 42 µM, respectively, in human liver microsomes, meanwhile all other isoforms exhibiting values > 300 µM.
