In vitro study | Hexachlorophene, the active ingredient of prescription drugs, is a potent activator of the KCNQ channel. It has a potentiating effect on KCNQ1 and KCNQ1/KCNE1 complexes. Hexachlorophene can effectively enhance the current amplitude of the KCNQ1/KCNE1 channel by stabilizing it in the open state, with an EC50 of 4.61±1.29 μm. In cardiomyocytes, 1 μm Hexachlorophene significantly shortened the action potential duration. In addition, Hexachlorophene can restore the function of long QT syndrome (LQTs) mutations. |
