MedKoo CAT#: 528528

CAS#: 104606-13-5

Description: R-56865 is a calcium and sodium channel antagonist potentially for the treatment of arrhythmias and ischaemic heart disorders. R-56865 showed marked cardioprotective properties: in the reperfusion period the agent markedly improved the restoration of left ventricular developed pressure, ATP and phosphocreatine, furthermore contracture development was reduced. On hypoxic cells, R-56865 selectively reduced the amplitude of hypoxia-induced membrane depolarization and partly counteracted the depression of synaptic transmission evoked by Schaffers collateral stimulation.
