Description
SKA-31 (40172-65-4) is a KCa3.1 and KCa2 potassium channel activator (EC50 =260, 2900, 2900 nM for KCa3.1, KCa2.1 and KCa2.2 respectively). Enhanced acetylcholine-induced EDHF dilator response in mouse carotid arteries and lowers blood pressure in mouse models at 30 mg/Kg.1,2 Evokes robust vasodilation in rat mesenteric arteries.3
Biological Activity
Activator of K Ca 3.1 and K Ca 2 channels (EC 50 values are 260, 2900, 2900 nM for K Ca 3.1, K Ca 2.1 and K Ca 2.2 respectively). Potentiates acetylcholine-induced EDHF-type dilations of mouse carotid arteries and lowers blood pressure in normotensive and hypertensive mice.
