SKA-31 a novel activator of SKCa and IKCa channels increases coronary flow in male and female rat hearts

摘要

AimsEndothelial SKCa and IKCa channels play an important role in the regulation of vascular function and systemic blood pressure. Based on our previous findings that small molecule activators of SKCa and IKCa channels (i.e. NS309 and SKA-31) can inhibit myogenic tone in isolated resistance arteries, we hypothesized that this class of compounds may induce effective vasodilation in an intact vascular bed, such as the coronary circulation.
