A series of six novel heterocyclic chalcone analogues 4(a–f) has been synthesized by condensing 2-acetyl-5-chlorothiophene with benzaldehyde derivatives in methanol at room temperature using a catalytic amount of sodium hydroxide. The newly synthesized compounds are characterized by IR, mass spectra, elemental analysis and melting point. Subsequently; the structures of these compounds were determined
通过使用催化量的氢氧化钠在室温下在甲醇中将 2-乙酰基-5-氯噻吩与苯甲醛衍生物缩合,合成了一系列六种新型杂环查耳酮类似物 4(a-f)。新合成的化合物通过红外、质谱、元素分析和熔点进行表征。随后; 这些化合物的结构是使用单晶 X 射线衍射确定的。通过使用各种体外模型,如DPPH自由基清除试验、ABTS自由基清除试验、铁还原抗氧化能力和铜离子还原抗氧化能力,筛选了所有合成化合物的抗氧化潜力。结果反映了对化合物抗氧化能力的结构影响。IC50 值说明所报告化合物的抗氧化活性从温和到良好。其中,发现具有对甲氧基取代基的 4f 作为抗氧化剂更有效。
