In SH-SY5Y human neuroblastoma cells, ICA-27243 produces membrane potential hyperpolarization that could be prevented by coadministration with the M-current inhibitors XE-991 and Linopirdine. ICA-27243 enhances both 86Rb+ efflux (EC50 = 0.2 μM) and whole-cell currents in Chinese hamster ovary cells stably expressing heteromultimeric KCNQ2/Q3 channels (EC50 = 0.4 μM). Activation of KCNQ2/Q3 channels is associated with a hyperpolarizing shift of the voltage dependence of channel activation (V1/2 shift of -19 mV at 10 μM)[1].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
