Tetramisole is an orally active, selective inward rectifier potassium channel agonist with an EC50 of approximately 30 μM for the Kir2.1 subunit. Tetramisole is also an anti-nematode agent that blocks neuromuscular transmission by non-competitive depolarization. Tetramisole promotes the forward transport of Kir2.1 channels, hyperpolarizes the resting potential (RP), shortens the action potential duration (APD), inhibits intracellular calcium overload and the PKA signaling pathway, and exerts anti-arrhythmic and anti-myocardial remodeling activities. Tetramisole can be used in cardiac electrophysiology research and research related to myocardial ischemia and heart failure.

SKP-451 is an ATP-sensitive potassium (K+) channel agonist.

SKP-451 relaxs the canine coronary artery, rabbit basilar artery, and vertebral artery. SKP-451 also reduces the mean arterial blood pressure of conscious spontaneously hypertensive rats (SHR). SKP-451 is promising for research of cardiovascular diseases.

The inhibitory effect of Ebio3 is also effective in pathogenic mutants of KCNQ2 (such as R75C and I238L), where it can inhibit outward currents by more than 80%. Ebio3 is expected to be used in the research of neurological diseases such as epilepsy.
