2-Chloro-5-cyanobenzene-1-sulfonamide is an ATP-sensitive myorelaxant. It blocks the calcium channels in muscle and pancreatic cells, thereby inhibiting the release of calcium ions. This leads to a reduction in the activity of the enzyme adenylate cyclase, which is responsible for generating a second messenger that causes muscle contraction. 2-Chloro-5-cyanobenzene sulfonamide has been shown to block pancreatic β cells and reduce insulin secretion. The drug's antihyperglycemic effects are due to its inhibition of glucose absorption by blocking sodium/glucose cotransport at the intestinal membrane level.
