Abstract

Gastric Cancer is one of the most lethal cancers with unmet clinical treatment and low 5-year survival rate. Schisantherin A is a major compound derived from Fructusschisandrae while its anti-tumor role remains nearly unknown. Here, we reported that schisantherin A had an anti-proliferation effect on gastric Cancer cell lines MKN45 and SGC-7901. Schisantherin A induced cell cycle arrest at G2/M phase and cell Apoptosis, and inhibited cell migration in gastric Cancer MKN45 and SGC7901 cells. Meanwhile, upregulation of cleaved caspase-9, cleaved Caspase-3 and cleaved PARP were accompanied with the loss of mitochondrial membrane potential (MMP). Moreover, schisantherin A induced ROS-dependent JNK phosphorylation with higher ROS production. The JNK Inhibitor and ROS scavenger NAC rescued the cell Apoptosis and cycle inhibition elicited by schisantherin A. Furthermore, the expression level of antioxidant factor Nrf2 was suppressed by schisantherin A. These findings suggest that schisantherin A possesses an anti-tumor activity via activation of ROS/JNK with Nrf2 inhibition, indicating that schisantherin A is a promising chemotherapeutic candidate for gastric Cancer.
