Thirty-three 1, 3-dihydro-2H-indolin-2-one derivatives bearing α, β-unsaturated ketones were designed and synthesized via the Knoevenagel condensation reaction. The cytotoxicity, in vitro anti-inflammatory ability, and in vitro COX-2 inhibitory activity of all the compounds were evaluated. Compounds 4a, 4e, 4i-4j, and 9d exhibited weak cytotoxicity and different degrees of inhibition against NO production
通过Knoevenagel缩合反应设计并合成了33种带有α,β-不饱和酮的1, 3-二氢-2H-二氢吲哚-2-酮衍生物。评估了所有化合物的细胞毒性、体外抗炎能力和体外COX-2抑制活性。化合物4a、4e、4i-4j和9d在LPS刺激的RAW 264.7细胞中表现出弱细胞毒性和不同程度的NO产生抑制作用。化合物4a、4i和4j的IC50值分别为17.81±1.86μM、20.41±1.61μM和16.31±0.35μM。化合物4e和9d表现出更好的抗炎活性,IC50值分别为13.51±0.48μM和10.03±0.27μM,低于阳性对照吡咯烷二硫代氨基甲酸铵(PDTC)。化合物 4e、9h、和9i表现出良好的COX-2抑制活性,IC50值分别为2.35±0.04μM、2.422±0.10μM和3.34±0.05μM。此外,通过分子对接预测了COX-2识别4e、9h和9i的可能机制。本研究结果
