Biochem/physiol Actions

Demethyleneberberine, a berberine metabolite, is a mitochondria-targeted antioxidant isolated from Cortex Phellodendri chinensis that exhibits multiple pharmacological activities including anti-microbial, anti-inflammatory, anti-diarrhea and anti-cancer. Demethyleneberberine alleviates ethanol-dependent oxidative stress by suppression of cytochrome CYP2E1 (P450 2E1), hypoxia inducible factor α (HIF-1α) and inducible nitric oxide synthase (iNOS). It appears that demethyleneberberine attenuates non-alcoholic fatty liver disease (NAFLD) through activation of AMPK.

Berberine, berberrubine, thalifendine, demethyleneberberine, jatrorrhizine, and columbamine are six natural protoberberine alkaloid (PA) compounds that display extensive pharmacological properties and share the same protoberberine molecular skeleton with only slight substitution differences. The oral delivery of most PAs is hindered by

Non-alcoholic fatty liver disease (NAFLD) has reached an epidemic level globally, which is recognized to form non-alcoholic steatohepatitis (NASH) by the "two-hit" model, including oxidative stress and inflammation. AMP-activated protein kinase (AMPK) has long been regarded as a key regulator

Excessive alcohol consumption induces oxidative stress and lipid accumulation in the liver. Mitochondria have long been recognized as the key target for alcoholic liver disease (ALD). Recently, the artificial mitochondria-targeted antioxidant MitoQ has been used to treat ALD effectively in
