Compound Shouwu Jiangzhi Granule regulates triacylglyceride synthesis to alleviate hepatic lipid accumulation.

Background: Nonalcoholic fatty liver disease (NAFLD) is a common chronic liver disease with few therapeutic options currently available. Traditional Chinese medicine has been used for thousands of years and exhibited remarkable advantages against such complicated disease for its "multi-component, multi-target and multi-pathway" characteristics. Compound Shouwu Jiangzhi Granule (CSJG) is a clinical empirical prescription for the treatment of NAFLD, but its pharmacological mechanism remains unknown.

Improved pharmacokinetics of tenofovir ester prodrugs strengthened the inhibition of HBV replication and the rebalance of hepatocellular metabolism in preclinical models.

Tenofovir (TFV) ester prodrugs, a class of nucleotide analogs (NAs), are the first-line clinical anti-hepatitis B virus (HBV) drugs with potent antiviral efficacy, low resistance rate and high safety. In this work, three marketed TFV ester drugs, tenofovir disoproxil fumarate (TDF), tenofovir alafenamide fumarate (TAF) and tenofovir amibufenamide fumarate (TMF), were used as probes to investigate the relationships among prodrug structures, pharmacokinetic characteristics, metabolic activations, pharmacological responses and to reveal the key factors of TFV ester prodrug design. The results indicated that TMF and TAF exhibited significantly stronger inhibition of HBV DNA replication than did TDF in HBV-positive HepG2.
