Novel quinoline derivatives were synthesized based on 6-amino-substituted quinoline, and antioxidant activity of these compounds is studied by p-nitroso-N,N-dimethylaniline assay. The rate of the reaction between OH radicals and quinoline derivatives is determined by photometric method and the obtained results are compared with that of well-known antioxidant vitamin C. Quinoline derivatives exhibit
以6-氨基取代喹啉为基础合成了新型喹啉衍生物,并通过对亚硝基-N , N-二甲基苯胺测定研究了这些化合物的抗氧化活性。通过光度法测定OH自由基与喹啉衍生物之间的反应速率,并将所得结果与众所周知的抗氧化剂维生素C进行比较。喹啉衍生物表现出显着的抗氧化活性,这在很大程度上取决于化合物的结构特征。还报道了光物理性质,例如紫外-可见光吸收和荧光最大值以及斯托克斯位移。为了揭示新型喹啉衍生物作为荧光探针的潜在应用,确定了量子产率的值,并根据化合物的结构特征解释了所得结果。
