Effects of calipteryxin and (3’S,4’S)-3’,4’-disenecioyloxy-3’,4’-dihydroseselin on various inhibitors induced by LPS in RAW 264.7 macrophages as described in “Methods.” The data were derived from three independent experiments and are expressed as the means ± S.D. (*) p <0.05, (**) p <0.01 and (***) p <0.001 indicate significant differences from the LPS-challenged group. (^###) p <0.001 indicates a significant difference from the unstimulated control group. Control (vehicle), LPS; (LPS + vehicle)-treated cells alone, M; only cells in the media
