Salvianolic acid B attenuated cisplatin-induced cardiac injury and oxidative stress via modulating Nrf2 signal pathway

Cardiovascular complications have been well documented as the downside to conventional Cancer chemotherapy. As a notable side effect of cisplatin (CDDP), cardiotoxicity represents a major obstacle to the successful treatment of Cancer. It has been reported that Salvianolic acid B (SalB) possesses cardioprotective quality. However, the effect of SalB on cardiac damage caused by conventional Cancer chemotherapy remains unclear. In this study, we clarified the protective effect of SalB on cisplatin-induced heart injury. Furthermore, in H9c2 cells, SalB dramatically reduced cisplatin-induced Apoptosis and oxidative stress by modulating the nuclear factor erythroid-2-related factor 2 (Nrf2) signaling pathway. In conclusion, SalB had great potential in mitigating cisplatin-induced cardiac injury. Furthermore, more attention should be placed on natural active compounds containing SalB with antioxidant effects for the treatment of cardiomyopathy.
