生物&药学活性

M201-A is a potent, selective ryanodine receptor 2 (RyR2) inhibitor, inhibits G-protein-gated atrial K+ channel (IKACh) with IC50 of 0.35 uM.

M201-A significantly reduces the diastolic Ca2+ in isolated rat ventricular cardiomyocytes, exhibits positive lusi-inotropic effects on rat heart.

M201-A inhibits G-protein-gated atrial K+ channel (IKACh) at an IC50 value of 0.35 μM, which is associated with a 38% increase in the atrial effective refractory period (ERP) and high atrial selectivity with an atrial ERP/ventricular ERP of 5.7.

M201-A inhibits rapid component of the delayed rectifier potassium current (IC50 value of 0.43 μM) but induced only a limited prolongation in the action potential duration in rabbit ventricular cells and human induced pluripotent stem cell-derived cardiomyocytes.

M201-A is an R-enantiomer of the active metabolite M201-R of K201.

M201-A is 5-fold more biologically active than K201 in humans due to protein binding rates.
