Abstract:

The neuroprotective effects of (-)-S.R-daurisoline on glutamate-induced neurotoxicity were studied in rat primary cortical cultures. The inhibitory effects of (-)-S.R-daurisoline on glutamate-elicited free intracellular Ca2+ increase were also studied in freshly dissociated single brain cells isolated from new born rat using AR-CM-MIC Cation Measurement System. Our experimental results demonstrated that (-)-S.R-daurisoline could obviously inhibit the neurotoxicity induced by glutamate and significantly increased cell viability in dose-dependent manner. In inhibiting glutamate-induced neurotoxicity, the IC50 value of (-)-S.R-daurisoline was found to be 3.4 mumol.L-1. (-)-S.R-daurisoline was also shown to markedly inhibit glutamate-elicited increase of cytosolic free Ca2+ concentration in dose-dependent manner with IC50 value of 2.0 mumol.L-1. Our results showed that (-)-S.R-daurisoline has an obvious protective effect on glutamate-induced neurotoxicity in primary cortical cultures. The protective mechanism of (-)-S.R-daurisoline may be relevant to inhibit Ca2+ influx into cells via glutamate-mediated ligand-gated ion channels.
