| Popis: | IMM-H004 [7-hydroxy-5-methoxy-4-methyl-3-(4-methylpiperazin-1-yl)-coumarin] is a novel derivative of coumarin, which played neuroprotective roles in brain ischemia in rats in previous studies. Although antiapoptosis and improving synapsis structure were proved, the effects and mechanisms of IMM-H004 in brain ischemia need further study. In this paper, the effect of IMM-H004 on H2O2-induced neurotoxicity in pheochromocytoma (PC12) cells was researched. Morphological observation, MTT method and PI/Hoechst staining were used to indicate cell viability and apoptosis. JC-1 and DCFH-DA were used to test mitochondrial membrane potential (MMP) and reactive oxygen species (ROS), respectively. The antioxidative activity was detected by Glutathione (GSH) and Total Antioxidant Capacity (TAC) Assay kits. Western blot was used to test apoptosis related proteins. Our results showed that treatment with 1-10 μM IMM-H004 markedly increased cell viability and decreased cell apoptosis induced by H2O2. Moreover, 1-10 μM IMM-H004 could enhance MMP and protect mitochondrial function. 1-10 μM IMM-H004 also could lower the ROS and raise the GSH and TAC level. Furthermore, 1-10 μM IMM-H004 could decrease the ratio of Bax/Bcl-2 and increase the ratio of p-AKT/AKT, which were related to apoptosis and survival. All these indicated that IMM-H004 protects PC12 cells against H2O2-induced neurotoxicity. Antioxidative and antiapoptosis may be the mechanisms of IMM-H004 in brain ischemia. These studies indicate that IMM-H004 might be a potential drug for treatment brain ischemia. |
