摘 要:Objective: To investigate the effect of Red Peony 801 (propyl gallate,PrG) on cyclooxygenase (COX) activity in murine peritoneal macrophages. Methods: A screening model for COX inhibitors in vitro based on murine peritoneal macrophages was used. COX-1 activity was reflected by the level of 6-ketoprostaglandin F1α(6-keto-PGF1α) in supernatants of cultured macrophages which were stimulated with calcium ionophore A23187 for a short-term, while COX-2 activity was reflected by the level of prostaglandin E2 (PGE2) in supernatants of cultured macrophages which were stimulated with lipopolysaccharide (LPS) for a long-term. Results: PrG did not affect A23187-induced, COX-1-derived 6-keto-PGF1α synthesis at the concentrations of 1×10-5, 5×10-6 mol/L (P0.05), but enhanced 6-keto-PGF1α synthesis at the concentrations of 1×10-6, 5×10-7, 1×10-7 mol/L (P0.01) in vitro, and showed a good dose-dependent manner. It inhibited LPS-induced, COX-2-derived PGE2 synthesis at the concentrations of 1×10-5,1×10-6 mol/L (P 0. 05). Conclusion: Within the range of 1×10-5 to 1×10-7 mol/L, PrG activated COX-1 at lower concentrations and inhibited COX-2 at higher concentrations in murine peritoneal macrophages.
