Inhibitory Effects of Glycyrrhetinic Acid on the Delayed Rectifier Potassium Current in Guinea Pig Ventricular Myocytes and HERG Channel

Figure 4

Inhibitory effect of GA on HERG current. Mean fractional block of HERG at a test potential of 0 mV at GA concentrations of 1, 5, and 10 μM was determined in HEK293 cells that stably expressed HERG channels.
