The Protective Effect of INH2BP, a Novel PARP Inhibitor 5-Iodo-6-Amino-1,2-Benzopyrone, Against Hydrogen Peroxide-Induced Apoptosis Through ERK and p38 MAPK in H9c2 Cells.

INH2BP (5-iodo-6-amino-1,2-benzopyrone), a poly-ADP ribose polymerase inhibitor, has been shown to possess anti-cancer, anti-viral, and anti-inflammation properties. The aim of this study was to investigate the protective effect of INH2BP against oxidative stress-induced apoptosis in H9c2 cardiomyoblast cells. While the treatment of H9c2 cardiomyoblasts cells with hydrogen peroxide (H2O2) caused a loss of cell viability and an increase in the number of apoptotic cells, INH2BP significantly protected the cells against H2O2-induced cell death without any cytotoxicity.
