title: Synthesis of the highly selective Na+/H+ exchange inhibitors cariporide mesilate and (3-methanesulfonyl-4-piperidino-benzoyl) guanidine methanesulfonate.
abstract: The syntheses of cariporide mesilate ((4-isopropyl-3-methanesulfonyl-benzoyl) guanidine methanesulfonate, HOE 642, CAS 159138-81-5), currently being clinically investigated as a protective drug in cardiac ischemia and reperfusion states, and of HOE 694 ((3-methanesulfonyl-4-piperidino-benzoyl)guanidine methanesulfonate, CAS 149725-40-6), widely used as a physiological and pharmacological research tool in studies comprising Na+/H+ exchange (NHE) inhibition, are described. Additionally, their selectivity on the different subtypes is disclosed.
