The effects of compounds on cell viability in LPS-induced RAW264.7 cells. RAW264.7 cells were treated with LPS (1 μg/mL) without or with compounds (0.39–100 μM) for 24 h. Cell viability was determined by MTT assay. Data are expressed as the mean value ± SD (n = 3). *** p < 0.001, ** p < 0.01, * p < 0.05 as compared to the control.
