Concentration-dependent effect of CLT on IKur. (a) I–V relationships of IKur during control, in the presence of CLT at 5 and 10 μM, and after washout. CLT inhibited IKur in a concentration–dependent manner, and the effect was partially reversed by 77.1% upon drug washout. (b) Concentration–response relationship of IKur inhibition by CLT at +50 mV. Symbols are the mean values of inhibiting effect in cells exposed to different concentrations. Solid lines are the best-fit Hill equation. IC50 was 7.4 μM, b was 1.8, and Emax was 87.1%. The numbers in parentheses are numbers of experiments.
