Phenylpropanoid glycosides from Scrophularia scorodonia: in vitro anti-inflammatory activity.

Five phenylpropanoid glycosides isolated from Scrophularia scorodonia L. (Scrophulariaceae), namely angoroside A (1), angoroside C (2), angoroside D (3), acteoside (4) and isoacteoside (5), had been evaluated as potential inhibitors of some macrophage functions involved in the inflammatory process. These compounds have been tested in two experimental systems: ionophore-stimulated mouse peritoneal macrophages and human platelets serve as source of COX-1 and 5-LOX, and mouse peritoneal macrophages stimulated with E. coli LPS are the means of testing for COX-2, NO and TNF-alpha activity. None of compounds assayed had a significant effect on LTC(4)-release from calcium ionophore-stimulated mouse peritoneal macrophages. However, the release of PGE(2) by mouse peritoneal macrophages stimulated with calcium ionophore was inhibited by most of these compounds. In the TXB(2)-release assay, acteoside (4), angoroside A (1) and angoroside C (2) showed a significant effect. These five compounds, except angoroside C (2) significantly inhibited LPS-induced PGE(2), NO and TNF-alpha in a concentration-dependent manner. In LPS-stimulated macrophages, the phenylpropanoid glycoside angoroside C (2) only had activity on NO. These results indicate that the pharmacology of these compounds may participate in the anti-inflammatory effect of Scrophularia scorodonia.
