Structure-activity relationships for the cyanoguanidine portion of the lead cardiac selective ATP-sensitivepotassiumchannel (KATP) opener (3) are described. The cyanoguanidine moity appears to be optimal since increasing or decreasing the distance between the aniline nitrogen and the pendant aromatic ring attenuates anti-ischemic potency/selectivity. Similarly, unfavorable results are obtained by replacement of
