生产及用途
2',5'-Dihydroxyacetophenone (DHAP, 2-Acetylhydroquinone, Quinacetophenone) 是二羟基苯乙酮异构体的混合物,用于食品调味。2',5'-Dihydroxyacetophenone 通过抑制 iNOS 的表达来显着抑制 NO 的产生。2',5'-Dihydroxyacetophenone 可通过阻断 ERK1/2 和 NF-κB 信号通路来显著地降低促炎细胞因子 TNF-α 和 IL-6 的表达水平。
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.
化学性质 淡黄绿色针状结晶。熔点202-203℃。溶于醇,难溶于醚和苯,几乎不溶于冷水。在碱溶液中呈黄色,遇三氧化铁呈蓝色。能升华。用途 用于有机合成。生产方法 由对苯二酚二乙酸酯在三氯化铝存在下反应而得。
