General description
A potent activator of Ca2+ -activated K+ channels of SK and IK types but not BK type channels. NS309 is at least 1000 times more potent than 1-EBIO and at least 30 times more potent than DC-EBIO when the compounds are compared on the same cell. NS309 blocks L-type Calcium channels with IC50 = 10 µM/L. Recently, this compound has been shown to produce endothelium-dependent hyperpolarizations in guinea pig carodid arteries by opening KCa2.3 and KCa3.1 channels demonstrating a new therapeutic option for treating hypertension.
