The present study describes synthesis of a novel series of 1,2,3,4-tetrazole integrated thieno[2,3-d]-pyrimidine hybrid 11a-l. Further, in vitro anti-microbial activities of the synthesized analogues 11a-l were evaluated against Gram-positive bacteria and Gram-negative bacteria, and fungal pathogens respectively. As a result, the analogues 11d and 11l were shown potent anti-bacterial activities 0.09-0
本研究描述了一系列新型 1,2,3,4-四唑集成噻吩并[2,3- d ]-嘧啶杂化物11a -l 的合成。此外,评价了合成的类似物11a - 1分别针对革兰氏阳性菌和革兰氏阴性菌以及真菌病原体的体外抗微生物活性。结果,类似物11d和11l对测试的病原体分别显示出有效的抗菌活性,分别为 0.09-0.48 µg/mL 和 0.07-0.51 µg/mL,并与标准环丙沙星 (0.08-0.34 µg/mL) 相比。同样,化合物11h和11l还显示出最高抑制区 (ZOIs),范围为13.20 ± 0.57至16.70 ± 0.50;和17.00 ± 0.00至17.50 ± 1.04 mm,分别针对指定的真菌病原体。随后,与金黄色葡萄球菌DNA旋转酶和黑曲霉酯酶活性位点进行分子对接研究表明,所有合成的衍生物11a - l均表现出良好的对接分数,在-9.2至-8.8 kcal/mol之间,并且较好与标准药物相比。
