We report the synthesis, antioxidant and antiproliferative activity and a QSARanalysis of synthetic diphenylpropionamide derivatives. Synthesis of these compounds wasachieved by direct condensation of 2,2- and 3,3-diphenylpropionic acid and appropriateamines using 1-propylphoshonic acid cyclic anhydride (PPAA) as catalyst. Compoundstructures were elucidated by NMR analysis and their melting points were measured. Thein vitro antioxidant activity of these compounds was tested by evaluating the amount ofscavenged ABTS radical and estimating ROS and NO production in LPS stimulatedJ774.A1 macrophages. All compounds were tested for their effect on viability of cells andresults demonstrated that they are not toxic towards the cell lines used. The cytotoxicactivity of all compounds was evaluated by a Brine Shrimp Test.
我们报告了合成的二苯丙酰胺衍生物的合成、抗氧化和抗增殖活性及QSAR分析。这些化合物的合成是通过直接冷凝2,2-和3,3-二苯丙酸与适当的胺,使用1-丙基磷酸环酐(PPAA)作为催化剂。通过NMR分析阐明了化合物的结构,并测量了它们的熔点。这些化合物的体外抗氧化活性通过评估清除ABTS自由基的量以及在LPS刺激的J774.A1巨噬细胞中估计ROS和NO的产生进行了测试。所有化合物均测试了其对细胞存活的影响,结果表明它们对所用细胞系无毒性。所有化合物的细胞毒性活性通过盐水虾实验进行了评估。
