Inhibition of IL-8 production (%) by isolated compounds 1–8 in LPS-treated PMNs (mean ± S.E.M.). Dex—dexamethasone. Statistical significance of differences was established by ANOVA with Tukey’s post hoc test. * p < 0.05, ** p < 0.001 vs. (+) LPS; # p < 0.001 vs. (−) LPS; a p < 0.05 vs. a concentration of 25 µM; b p < 0.05 vs. a concentration of 5 µM.
