5'-triphosphate-sensitive potassium (K(ATP)) channelopeners is described. As part of our efforts directed toward identifying novel, bladder-selective potassiumchannelopeners (KCOs) targeted for urge urinary incontinence (UUI), we found that bioisosteric replacement of the N-cyanoguanidine moiety of pinacidil (1, Figure 1) with a diaminocyclobutenedione template afforded squaric acid analogue 2, the prototype
