ORM‐11372 is a potent and highly selective NCX 1.1 inhibitor, inhibits human NCX 1.1 reverse and forward currents with IC50 of 5 and 6 nM respectively.ORM‐11372 weakly inhibits human cardiac sodium 1.5 (I Na) and hERG KV11.1 currents (I hERG) with IC50 of 23.2 and 10.0 uM.ORM‐11372 decreased both the outward and inward currents of hiPSC‐CMs with IC50 of 4.8 and 5.6 nM respectively, reduced the magnitude of outward I NCX (the reverse mode) in rat primary ventricular CMs with IC50 of 11.3 nM.ORM‐11372 concentration‐dependently inhibited the calcium efflux signa with an IC50 of 142 and 164 nM for experimental conditions increasing intracellular calcium and eliciting NCX forward mode activity, repectively.ORM‐11372 induced positive inotropic effects of 18 ± 6% and 35 ± 8% in anaesthetized rats with myocardial infarctions and in healthy rabbits respectively with no other haemodynamic effects.
