Effect of compounds 1–7 on the expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) proteins in RAW264.7 macrophage cells by immunoblot analysis. (A) Immunoblots of iNOS and β-actin; (B) Immunoblots of COX-2 and β-actin. The values are mean ± SEM. (n = 6). Relative intensity of the lipopolysaccharide (LPS) alone stimulated group was taken as 100%; * Significantly different from LPS alone stimulated group (* p < 0.05); a stimulated with LPS; b stimulated with LPS in the presence of 1–7 (10 µM).
