Abstract Synthesis, characterization and biological activity of novel 4,5-diaryl/heteroaryl thiophene-2-carboxylic acid derivatives are described. Aryl/heteroaryl esters were converted to substituted thiophene esters via a Vilsmeier-Haack reaction, which were then hydrolyzed to 4,5-diaryl/heteroaryl thiophene-2-carboxylic acid derivatives 8a–h. All products were characterized by 1H NMR, 13C NMR, IR
摘要 描述了新型 4,5-二芳基/杂芳基噻吩-2-羧酸衍生物的合成、表征和生物活性。芳基/杂芳基酯通过 Vilsmeier-Haack 反应转化为取代的噻吩酯,然后水解为 4,5-二芳基/杂芳基噻吩-2-羧酸衍生物 8a-h。所有产品均通过 1H NMR、13C NMR、IR 和 MS 进行表征。评估了合成化合物对两种革兰氏阳性菌和两种革兰氏阴性菌的抗菌活性,以及它们对 PC-3 细胞系(人前列腺癌细胞系)的抗癌活性。
