    Rottlerin, a polyphenol isolated from Mallotus Philippinensis, has been recently used as a selective inhibitor of PKC delta, although it can inhibit many kinases and has several biological effects. The current study confirms the antioxidant property of Rottlerin against the 2,2-diphenyl-1-picrylhydrazyl radical (DPPH) in vitro and against oxidative stress induced by H(2)O(2) and by menadione in culture cells. We also demonstrate that Rottlerin prevents TNFalpha-dependent NFkappaB activation in MCF-7 cells and in HT-29 cells transfected with the NFkappaB-driven plasmid pBIIX-LUC, suggesting that Rottlerin can inhibit NFkappaB via several pathways and in several cell types.
