体外研究 | 2,5-Dihydroxyacetophenone significantly inhibits NO production via the suppression of iNOS expression and significantly decreases levels of the pro-inflammatory cytokines TNF-α and IL-6 via the down-regulation of their mRNA expression in LPS-stimulated RAW264.7 cells. 2,5-Dihydroxyacetophenone potently inhibits the phosphorylation of extracellular signal-related kinase (ERK) 1/2 and the nuclear translocation of nuclear factor-κB (NF-κB) p65 in LPS-stimulated cells. |
