A short synthesis of the natural products (8), (10) and the unnatural (13) was achieved based on a efficient esterification reaction of the benzylated gallic acid 5 with the α,β-glucopyranoses 11 and 4, respectively.
By use of the model virus, expressing the HCV envelope proteins E1 and E2, bioassay guided separation of the MeOH extract from Rosa rugosa Thunb. disclosed tellimagrandin I (1) together with eugeniin (2) and casuarictin (3) as the potent HCV invasion inhibitors. Furthermore, structure-activity relationship analysis of some relative tannins including the synthesized analogs elucidated the partial structures crucial for potent activity of 1.
