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.

Ethyl caffeate is a potent chemopreventive compound against skin carcinogenesis caused by solar UV exposure.

Isoliquiritin apioside isolated from Glycyrrhizae radix rhizome significantly decreases PMA-induced increases in MMP9 activities and suppresses PMA-induced activation of MAPK and NF-κB.
