Cimifugin (CIM) is a chromone component of Saposhnikoviae Radix, which has good anti-inflammatory activity. In this study, 21 CIM amino acid ester derivatives were synthesized. CIM and its derivatives CIM 2, CIM 3, CIM 7, and CIM 11 have good inhibitory effects on the release of nitric oxide in lipopolysaccharide-induced mouse macrophages (RAW 264.7) inflammation model. The inhibitory effect of CIM

一氧化氮的释放具有良好的抑制作用。CIM 3的抑制效果是CIM的3倍。IC 50NO抑制率分别为0.61±0.06、1.53±0.11μmol/L。CIM 3对细胞上清液中IL-1β、TNF-α和IL-6的释放也具有最好的抑制作用。CIM 3显着减轻小鼠耳肿胀,延长小鼠热痛阈,并减少体内
乙酸引起的扭体次数。这些结果表明CIM 3的抗炎镇痛活性明显优于原药CIM。
