Description: ICA069673 is a heteromeric Kv7 channel activator. It is selective for Kv7.2/7.3 over Kv7.3/7.5 (EC50s = 0.69 and 14.3 μM, respectively). ICA-069673 inhibited spontaneous phasic, pharmacologically induced, and nerve-evoked contractions in DSM isolated strips in a concentration-dependent manner. . ICA-069673 decreased the global intracellular Ca(2+) concentration in DSM cells, an effect blocked by the L-type Ca(2+) channel inhibitor nifedipine. ICA-069673 hyperpolarized the membrane potential and inhibited spontaneous action potentials of isolated DSM cells, effects that were blocked in the presence of XE991.
