Controlling inflammation and oxidation can ameliorate ALI. In the present study, we aimed to determine whether 3,4-Dihydroxyacetophenone(compound 1)could ameliorate lipopolysaccharide(LPS)-induced ALI by suppressing inflammation and oxidation. In this study, compound 1 reduced LPS-induced inflammatory cytokines and oxidative stress in RAW 264.7 cells. Moreover, compound 1 suppressed the expression of inflammatory protein p65, inhibited IkBα phosphorylation, decreased the nuclear translocation of p65, and increased the expressions of anti-oxidative protein nuclear factor erythroid 2-related factor 2(Nrf-2) and heme oxygenase-1(HO-1), which was reduced by LPS, in leukemia cells in mouse macrophage(RAW 264.7) cells. Furthermore, compound 1 could also ameliorate LPS-induced ALI in vivo, with a reduction of inflammatory cytokines, oxidative stress, and nuclear factor-kappa B(NF-κB)signaling pathway activation. This study emphasized the anti-inflammatory and anti-oxidative activities of compound 1, which could be a valuable therapeutic agent against ALI.展开更多
