Demethyleneberberine chloride, a natural mitochondria-targeted antioxidant, mitigates colitis in mice and suppresses inflammatory responses by blocking the NF-κB pathway and modulating the equilibrium of Th cells. It is also recognized as an AMPK activator for investigating non-alcoholic fatty liver disease (NAFLD) [1] [2] [3].

Demethyleneberberine, which is composed of a potential antioxidant structure, could penetrate the membrane of mitochondria and accumulate in mitochondria either in vitro or in vivo.Demethyleneberberine suppresses CYP2E1, hypoxia inducible factor α, and inducible nitric oxide synthase, which contributes to oxidative stress and restored sirtuin 1/AMP-activated protein kinase/peroxisome proliferator-activated receptor-γ coactivator-1α pathway-associated fatty acid oxidation in chronic ethanol-fed mice.
