  Synthesis, structure–activity relationships and biological evaluation of dehydroandrographolide and andrographolide derivatives as novel anti-hepatitis B virus agents

  摘要：

  Dehydroandrographolide and andrographolide, two natural diterpenoids isolated from Andrographis paniculata possessed activity against HBV DNA replication with IC50 values of 22.58 and 54.07 mu M and low SI values of 8.7 and 3.7 in our random assay. Consequently, 48 derivatives of dehydroandrographolide and andrographolide were synthesized and evaluated for their anti-HBV properties to yield a series of active derivatives with lower cytotoxicity, including 14 derivatives against HBsAg secretion, 19 derivatives against HBeAg secretion and 38 derivatives against HBV DNA replication. Interestingly, compound 4e could inhibit not only HBsAg and HBeAg secretions but also HBV DNA replication with SI values of 20.3, 125.0 and 104.9. Furthermore, the most active compound 2c with SI value higher than 165.1 inhibiting HBV DNA replication was revealed with the optimal logP value of 1.78 and logD values. Structureactivity relationships (SARs) of the derivatives were disclosed for guiding the future research toward the discovery of new anti-HBV drugs. (C) 2014 Elsevier Ltd. All rights reserved.

  inhibitory activity by hydrogenation, oxidation, or acetylation to become four derived compounds, 9, 10, 11, and 12. All of the compounds significantly decreased TNF-α, IL-6, macrophage inflammatory protein-2 (MIP-2), and nitric oxide (NO) secretions from LPS/IFN-γ stimulated RAW 264.7 cells. Compounds 5, 11, and 12 exerted the strongest inhibitory effect on NF-κB-dependent transactivation in the RAW 264
