Figure 1. Effects of phenolic amides and OGD on cell viability. (A) Chemical structure of phenolic amides (1-5). Thereinto, the compound 3 is Lyciumamide A (LyA). (B) MTT assay was employed to investigate the protective effects of phenolic amides against OGD-induced cytotoxicity. The concentrations of these compounds is 40 μM. Data were represented as means ± SD (n=6). *p < 0.05 compared with control group; #p < 0.05 compared with OGD group.
