radical scavenging activity of novel chromone-carbamodithioate analogues was quantitatively estimated by spectrophotometric method. Whereas, molecular docking studies were performed with the active site of cyclooxygenase-2 to identify hydrogen bonding, hydrophobic and ionic interactions between protein and ligands. The compounds 7g and 7h demonstrated potent antioxidant activity with IC50 of 1.405 ± 0
由2,3-二甲基-7-(环氧乙烷-2-基甲氧基)-4H-铬-4-酮(5),二硫化碳和可商购的无环和环状仲胺合成了新的铬氨碳二硫酸酯(7a-i)。乙腈,收率好至极好。通过分光光度法定量估计了新的色酮-氨基甲二硫代磺酸盐类似物的自由基清除活性。鉴于分子对接研究是与环氧合酶2的活性位点进行的,以鉴定蛋白质与配体之间的氢键,疏水和离子相互作用。化合物7 g和7 h具有IC 50的强效抗氧化活性 与抗坏血酸相比分别为1.405±0.019 mM和1.382±0.35 mM。
