Fig. 1. Effects of TS, RSV and TMS on cell viability and Glu-induced cytotoxicity. (A) Chemical structures of TS, RSV and TMS. (B) HT22 cells were incubated for 24 h with TS, RSV or TMS at indicated concentrations. (C) HT22 cells were pretreated for 12 h with TS, RSV or TMS at indicated concentrations. Then, the cells were stimulated with culture medium supplemented with 2 mM Glu for 24 h. MTT assay for cell viability was performed as described under Materials and Methods. Data are expressed as means ± SE from 3 and 4 experiments. *p<0.05 with respect to the untreated control group (Con). **p<0.05 with respect to Glu-treated group.
