Effect of clobenpropit (CLO) on cyclooxygenase-2 (COX-2) levels in lipopolysaccharide (LPS)-induced mice brains. LPS-CLO-1 and LPS-CLO-3 refer to administration of clobenpropit (1 or 3 mg/kg, p.o., respectively) and lipopolysaccharides (250 μg/kg, i.p.). CLO treatment reduced the activity of COX-2 induced by LPS. The results are expressed as mean ± SEM (n = 6). One-way ANOVA (F(3,20) = 33.67, p < 0.001) was followed by Tukey–Kramer multiple comparisons tests. *** p < 0.001 as compared to the control group; ns, not significant as compared to the control group; ### p < 0.001 as compared to the LPS-treated group.
