Inhibiton Assay : hERG: The hERG inhibition study aims at quantifying the in vitro effects of compounds of the invention on the potassium-selective IKr current generated in normoxic conditions in stably transfected HEK 293 cells with the human ether-a-go-go-related gene (hERG).Whole-cell currents (acquisition by manual patch-clamp) elicited during a voltage pulse were recorded in baseline conditions and following application of tested compounds (5 minutes of exposure). The concentrations of tested compounds (0.3 μM; 3 μM; 10 μM; 30 μM) reflect a range believed to exceed the concentrations at expected efficacy doses in preclinical models.The pulses protocol applied is described as follow: the holding potential (every 3 seconds) was stepped from −80 mV to a maximum value of +40 mV, starting with −40 mV, in eight increments of +10 mV, for a period of 1 second. The membrane potential was then returned to −55 mV, after each of these incremented steps, for 1 second and finally repolarized to −80 mV for 1 second.
