L-735821

L-735821 is a Potassium channel blocker and an antagonist of IKs. L-735821 inhibits the KCNQ1 channel activity with an EC50 of 0.08 μM. L-735821 can increase IKs and IKr current-voltage relations in rabbit ventricular myocytes. L-735821 fully abolishes IKs in isolated human ventricular myocytes at 100 nmol/L. L-735821 can easily enter single myocytes[1][2][3][4].
