Outline
Twenty target compounds were synthesized by the reduction reaction of HUANG Minglong and Friedel-Crafts acylation reaction in this study. The inhibitory effects of the new compounds were tested on NO production in LPS-induced mouse macrophage RAW264.7 cells, a cellular inflammation model. The structure-activity relationships were discussed. The structures of target compounds were confirmed by ESI-MS, 1H NMR and 13C NMR. In vitro activity experiments showed that 18 compounds had certain anti-inflammatory effects at the concentration of 40 μmol·L-1, of which 9a, 8b, 7c and 9c showed strong anti-inflammatory activities, and IC50 of 7c and 9c were comparable to the positive control drug ibuprofen.
