Siamois polyphenols and withasteroids dose-dependently inhibit NFκB-dependent reporter gene expression. A) Chemical formulas of quercetin, kaempferol, eriodictyol, WP283, and withaferin A. B) L929sA cells, stably transfected with p(IL6κB)350 hu.IL6P-luc+, were left untreated or were pretreated with a concentration range of 100-50-25-12.5 μM Siamois polyphenol (quercetin, kaempferol, eriodictyol, WP283) or 3-1.5-0.75-0.38 μM withaferin A for 2 h, and then stimulated with 2000 IU/ml TNF for 4 h. NFκB-dependent reporter gene expression was normalized for PGK housekeeping reporter gene expression. Data of two independent experiments, each done in triplicate, are presented as mean ± S.E.M.
