SPRC protects hypoxia and re-oxygenation injury by improving rat cardiac contractile function and intracellular calcium handling.

S-Propargyl-L-cysteine (SPRC, also named as ZYZ-802) is a new compound synthesized in our lab. We investigated whether SPRC has exerted protective effects against cardiac hypoxia/re-oxygenation (H/R) and also explored its mechanisms. In our study, isolated ventricular myocytes were subject to a simulated hypoxia solution for 30 min to induce cell injury.
