title: Discovery of a novel potent Na+/Ca2+ exchanger inhibitor: design, synthesis and structure-activity relationships of 3,4-dihydro-2(1H)-quinazolinone derivatives.
abstract: Design, synthesis and structure-activity relationships for 3,4-dihydro-2(1H)-quinazolinone derivatives with the inhibitory activities of the Na(+)/Ca(2+) exchanger are discussed. These studies based on lead compound 1a lead to the discovery of a structurally novel and highly potent inhibitor against the Na(+)/Ca(2+) exchanger 4f (SM-15811), which directly inhibited the Na(+)-dependent Ca(2+) influx via the Na(+)/Ca(2+) exchanger in cardiomyocytes with a high potency.
