a randomized, double-blind trial of antroquinonol in patients with chronic hepatitis b

Conditions: HBV

Summary: hepatitis b virus infection is a worldwide disease and is still the most common cause of hepatocellular carcinoma (hcc).existing treatments for hepatitis b infection have various side-effects including renal toxicity and drug resistance or failure.

hepatitis b virus infection is a worldwide disease and is still the most common cause of hepatocellular carcinoma (hcc). those carriers in china account for 33% of all chronic carriers globally. a big epidemiological study of patients with chronic hepatitis b has revealed that baseline hbv dna level or cirrhosis is an independent predictor for the occurrence of hcc. antroquinonol is a new chemical entity isolated from the mycelium of antrodia camphorata, which showed interesting anticancer and anti-inflammatory activities.previous studies have indicated that signaling molecules, such as pi3k, ampk, and mtor, participate in antroquinonol-induced cancer cell death, whereas nrf2 and nf-kb are involved in the anti-inflammatory effects of antroquinonol. moreover, we also found the administration of antroquinonol also differentially modulated t cell activity and reduced il-18 production, but enhanced the activation of nrf2 and, thus, suppressed oxidative stress by animal studies. these results demonstrate the potential applications of antroquinonol in treating hepatitis b.
