Effects of SC, SCO, SCA, SCOA, and SCH and H2O2 treatment with or without SC, SCO, SCA, SCOA, and SCH pretreatment on cell viability of 3T3-L1 cells: (A) 3T3-L1 preadipocytes were treated with SC, SCO, SCA, SCOA, or SCH (0–500 μg/mL) for 48 h, and cell viability was assessed. Results are shown as mean ± SD of three independent experiments. In each group of columns related to each concentration of sample, differences exist between columns labeled with different letters, p < 0.05; (B) 3T3-L1 adipocytes were pretreated with 100 μg/mL SC, SCO, SCA, SCOA, or SCH, followed by treatment with 2 mM H2O2 for 24 h, and cell viability was assessed. Results are shown as mean ± SD of three independent experiments. Different letters (in a, b, c, d, and e) mean statistically significant differences at p < 0.05. In each group of columns related to each treatment, differences exist between columns labeled with different letters, p < 0.05.
