Effects of limonoids on the LPS-induced expression of IL-8 in HT-29 cells. HT-29 cells were treated with compounds 1–13 (1 and 10 µM) for 2 h and stimulated with 100 ng/mL LPS for 18 h. The viability of cells was then determined using an MTT assay (A) and the level of IL-8 in the culture media was measured with an ELISA kit (B). The values are expressed as mean ± standard deviation of three individual experiments. # p < 0.01, compared to the control group; * p < 0.05, ** p < 0.01, *** p < 0.001, compared to the LPS-treated group.
