(a) Inhibition of compounds (10 μM) against nitric oxide (NO) production in LPS-stimulated RAW264.7 cells; (b) Inhibition of compounds (20 μM) on LPS-stimulated TNF-α release from RAW264.7 cells (Inhibition of compounds (10 μM) on TNF-α production is given in Fig. S2). Asterisks dictate the significant effects of the tested compounds compared to that of LPS treated cells. One-way ANOVA with Bonferroni’s post-test (*p < 0.001 for each agonist) used for analyzing data. The data are mean ± SEM of three experiments. The results remained similar when experiments were performed using different cells. Control indicates the cell only. (c) Anti-inflammatory efficacies of the tested compounds on suppressing the mRNA expression of iNOS and TNF-α in LPS-stimulated RAW264.7 cells by RT-PCR. (Full-length blots are given in Supplementary information).
