Effects of 1, 9, and inhibitors on signal-regulated kinases in RAW 264.7 cells. RAW 264.7 cells were seeded into a 6-well plate (3 × 10⁵ cells/well) and incubated for 2 hours. Then they were stimulated with LPS of 100 ng/well with or without various concentrations of a dimethyl sulfoxide (DMSO) solution of a 5,7-dihydroxyflavone analogue or an inhibitor for 15 min. Detailed procedures for the protein collection/evaluation are described in the text. Labels present the compounds and concentrations (μM). Data are expressed as mean ± SD from 3 independent experiments. Control group were presented by the open circles. ^∗Significance: p < 0.05 and ^∗∗ and ^‡Significance: p < 0.01.
