In this study, 20 new derivatives of caffeic acid esters were synthesized and their inhibitory activities against the lipopolysaccharide (LPS)-induced nitric oxide (NO) production in RAW264.7 macrophages were determined. Compounds 3l, 3r, 3s and 3t were found to decrease nitrite levels in a dose-dependent manner in LPS-induced cells and showed potent inhibitory activities against the NO production in RAW264.7 macrophages with IC50 values of 7.4, 5.9, 3.3 and 2.2 μM, respectively. They could be selected as compromising compounds for the later pharmacological study.
在本研究中,合成了20种新的咖啡酸酯衍生物,并测定了它们对脂多糖(LPS)诱导的RAW264.7巨噬细胞中一氧化氮(NO)产生的抑制活性。发现化合物3l、3r、3s和3t能以剂量依赖的方式降低LPS诱导细胞中的亚硝酸盐水平,并对RAW264.7巨噬细胞中NO的产生表现出强大的抑制活性,IC50值分别为7.4、5.9、3.3和2.2 μM。它们可被选为后续药理学研究的潜在化合物。
