A series of Schiff’s bases (E)-N-2-aryliden-2-(4-methyl-2-oxo-2H-chromen-7-yloxy)acetohydrazides 2a-l and N-(2-(substituted phenyl)-4-oxo-thiazolidin-3-yl)-2-(4-methyl-2-oxo-2H-chromen-7-yloxy)acetamides 3a-l were synthesized and evaluated for their antioxidant activity by the phosphomolybdenum method. Most of the Schiff’s bases and thiazolidine-4-ones bearing two hydroxyl groups on the phenyl ring showed excellent antioxidant activity in comparison with ascorbic acid. Preliminary investigation on cytotoxic and antifungal activity was done on some representative samples.
一系列席夫碱(E)-N-2-芳基亚甲基-2-(4-甲基-2-氧-2H-色烯-7-基氧)乙酰肼2a-l和N-(2-(取代苯基)-4-氧-噻唑烷-3-基)-2-(4-甲基-2-氧-2H-色烯-7-基氧)乙酰胺3a-l被合成并通过磷钼酸法评估其抗氧化活性。与抗坏血酸相比,大多数具有苯环上两个羟基的席夫碱和硫氮杂酮显示出优异的抗氧化活性。对一些代表性样品进行了初步的细胞毒性和抗真菌活性研究。
