Background:

SERCA2a activator 1 (Compound A) is a sarco/endoplasmic reticulum Ca2+-dependent ATPase 2a (SERCA2a) activator. SERCA2a activator 1 attenuates phospholamban inhibition and enhances the systolic and diastolic functions of the heart. SERCA2a activator 1 can be used for heart failure[1].

SERCA2a activator 1 (Compound A) activates the Ca2+-dependent ATPase activity of cardiac sarcoplasmic reticulum (SR) vesicles but not that of skeletal muscle SR vesicles that lack phospholamban (PLN). The surface plasmon resonance assay reveals a direct interaction between SERCA2a activator 1 and PLN, suggesting that the binding of SERCA2a activator 1 to PLN attenuates its inhibition of SERCA2a, resulting in SERCA2a activation[1]. SERCA2a activator 1 also increases the Ca2+ transients and contraction and relaxation of isolated adult rat cardiomyocytes. In isolated perfused rat hearts, the SERCA2a activator 1 enhances systolic and diastolic functions[1].

SERCA2a activator 1 (Compound A; 30mg/kg; intravenous injection; male Wistar rats) treatment significantly enhances the diastolic function in anesthetized normal rats[1].
