Anti-HBV active constituents from Piper longum.
Two new compounds and anti-HIV active constituents from Illicium verum.
Two new compounds named illiverin A (1) and tashironin A (8) were isolated from the roots of Illicium verum, together with seven known compounds:
Swerilactones A and B, anti-HBV new lactones from a tradtional Chinese herb: Swertia mileensis as a treatment for viral hepatitis.
In vitro antihepatitis B virus (HBV) assay on Hep G 2.2.15 cell line showed that compound 1 inhibited HBsAg and HBeAg secretion with IC(50) values of 3.66 and 3.58 mM, respectively.
Two New Lignans and Anti‐HBV Constituents from Illicium henryi
Two new lignans, dihydrodehydrodiconiferyl alcohol and threo‐4,9,9′‐trihydroxy‐3,3′‐dimethoxy‐8‐O‐4′‐neolignan 7‐O-α‐rhamnopyranoside, were isolated from Illicium henryi, together with ten known compounds, 3–12, and their structures were elucidated by extensive spectroscopic analyses.
Xanthones with anti-hepatitis B virus activity from Swertia mussotii.
Two new xanthones, 8-O-β-D-glucopyranosyl-1-hydroxy-2,3,5-trimethoxyxanthone (1) and 8-O-[β-D-xylopyranosyl-(1 → 6)-β-D-glucopyranosyl]-1-hydroxy-2,3,5-trimethoxyxanthone (2), along with eighteen
