Eurycomalactone is a natural product isolated from Eurycoma longifolia Jack., acts as a potent NF-κB inhibitor( IC50 of 0.5 μM).?Eurycomalactone inhibits protein synthesis, depletes cyclin D1, but does not affect TNFα-induced degradation of IκBα or the phosphorylation of IKKα/β and IκBα.

Phyllanthin is widely used as hepatoprotective and antigenotoxic and inhibit function of P-gp.

Tomatidine decreases inducible NO synthase and COX-2 expression through suppression of I-κBα phosphorylation, NF-κB nuclear translocation and JNK activation, which in turn inhibits c-jun phosphorylation and Oct-2 expression.
