The hypoglycemic effect of sulfonylureas and their analogues results from their binding to a high affinity site in the B-cell plasma membrane. This site seems to be a structural component of the ATP-sensitive K(+)-channel and represents the pancreatic sulfonylurea receptor. Binding of sulfonylureas causes closure of the ATP-sensitive K(+)-channel and thereby initiates a chain of events eventually leading to the release of insulin. Diazoxide inhibits insulin secretion via opening of the ATP… CONTINUE READING
