17 chalcone analogues were synthesized from 7-methoxy-3,4-dihydronaphthalen1(2H)-one and various aromatic aldehydes under basic condition. These chalcone analogues were evaluated for the neuroprotective effects against glutamate-induced neurotoxicity. In the cell based assay, we have identified a compound C01 as neuronal cell protection agent. This compound inhibits the Ca2+ influx and cellular ROS accumulation inside the cell and the FACS analysis using annexin V and PI shows that C01 significantly reduced apoptotic or dead cell death induced by 5 mM glutamate. Further, western blot analysis indicates that glutamate induced activation of MAPKs were inhibited by compound C01 treatment. Also, the C01 increases the anti-apoptotic protein Bcl-2 and decreases pro-apoptotic protein Bax. C01 protects neuronal cells from apoptosis by preventing the translocation of AIF into nucleus. Taken together, treatment of C01 results in decreasing the neurotoxicity induced by 5 mM of glutamate. As a result, we confirm that C01 has neuroprotective effects against glutamate induced toxicity in HT22 hippocampal neuronal cells.
