This article reviews current knowledge on KATP channel drug binding modes through cryogenic electron microscopy, highlighting distinct binding sites in the sulfonylurea receptor and potential mechanisms of drug action, but reports no new experimental results.

This study identified certain benzopyran derivatives with a bulky tert-butyloxycarbonylamino group as effective KATP channel openers that inhibit insulin secretion in rat pancreatic islets.

This study developed a new method to analyze Cantú syndrome mutations in KATP channels, finding that while Kir6.1 mutations increase sensitivity to potassium channel openers, SUR2B mutations show reduced sensitivity, but both result in marked hyperpolarization compared to wild-type channels under basal conditions.

This study found that several newly synthesized dihydrobenzopyran compounds inhibited insulin secretion and had vasorelaxant activity, with some more potent than reference KATP channel activators, though compound 21 functioned as a Ca2+ entry blocker.

This study found that activating KATP channels with pinacidil may reduce antioxidant levels and mortality in honey bees, suggesting a role in regulating antiviral immunity through reactive oxygen species.
