Abstract:
Objective(s): Stroke may cause severe neuronal damage. The sesamin have been demonstrated to possess neuroprotection by its antioxidant and anti-inflammatory properties. One sesamin derivative was artificially composited, ۱, ۲-bis [(۳-methoxyphenyl) methyl] ethane-۱, ۲-dicaroxylic acid (MMEDA) had been developed to study its antioxidative activity and neuroprotection. Materials and Methods: The infaction of Sprague Dawley (SD) rats and hypoxia models of BV-۲ microglia or PC۱۲ cells were investigated for in vivo and in vitro test respectively. Lipid peroxidation and reactive oxygen species (ROS), prostaglandin E۲ (PGE۲) and related signaling pathways from hypoxic cells were analyzed by ELISA or Western blot assay, respectively. Results: MMEDA showed a protective effect when given ۹۰ min after the focal cerebral ischemia. The neuroprotection of MMEDA was further confirmed by attenuating ROS and PGE۲ release from hypoxic BV-۲ or PC۱۲ cells. MMEDA significantly reduced hypoxia-induced JNK and caspase-۳ (survival and apoptotic pathways) in PC۱۲ cells. Conclusion: The neuroprotective effect of MMEDA on ischemia/hypoxia models was involved with its antioxidative activity and anti-inflammatory effects. These results suggest that MMEDA exert effective neuroprotection against ischemia/hypoxia injury.
