hERG - Pharmacology of Mexiletine, Quinidine, Ondansetron, Ranolazine (Results CiPA Phase I Study)
Patchliner data and applications:
Cells were kindly provided by Charles River.
The effect of four compounds on hERG currents were investigated, using the CiPA voltage step protocol. Measured on the Patchliner the perforated patch methodology (Escin) and multi-hole chips (4 holes per well) were used. The IC50 value of Mexiletine was determined as 77.3 µM, Quinidine as 1.04 µM, Ondansetron as 1.13 µM and Ranolazine as 11.9 µM.
