Popis: | Bioactivity-guided fractionation and purification of Cistus parvillorus led to the isolation of two flavan-3-ol derivatives; gallocatechin (1) and epigallocatechin (2) and two flavonoid glycosides; avicularin (3) and trans-tiliroside (4). The structures of the compounds were elucidated on the basis of NMR and ESIMS data. All compounds were isolated from C. parviflorus for the first time. Compounds 2 and 3 exhibited antiinflammatory activity through decreasing the NOS2 and COX2 levels on LPS+IFN-gamma treated RAW 264.7 cells. Molecular docking studies of avicularin, the most potent compound, were carried out in the active sites of NOS2 and COX2 to predict the most plausible binding modes and support the experimental data. |
