Fig. 5From: Limonoids from the barks of Chukrasia tabularis and their anti-inflammatory activityEffects of compound 18 on the production of TNF-α, NO and IL-6 in LPS-induced macrophages. The macrophages were incubated with LPS (1 μg/mL) and treated with compound 18 (5.2 and 20.8 μmol/L) for 24 h. A The levels of TNF-α, B NO, and C IL-6 in the supernatant were assayed using ELISA kits. All values given are the mean ± SD. **p < 0.01 compared to the LPS groupBack to article page
