All synthesized products were characterized by FT‐IR, 1H, and 13C NMR spectral data, elemental analyses, and mass spectrometry. The antibacterial and antifungal activities of these compounds were evaluated against Staphylococcus aureus and Bacillus subtilis as Gram‐positive bacteria, Escherichia coli and Pseudomonas aeruginosa as Gram‐negative bacteria, and the fungus Candida albicans. The results revealed
在乙醇中,4-氧代四氢-2 H-硫代吡喃-3-羧酸甲酯与肼衍生物的缩合反应合成了一系列双环吡唑酮。所有合成的产物均通过FT-IR,1 H和13 C NMR光谱数据,元素分析和质谱进行表征。评价了这些化合物对金黄色葡萄球菌和枯草芽孢杆菌(革兰氏阳性菌),大肠杆菌和铜绿假单胞菌(革兰氏阴性菌)和真菌白色念珠菌的抗菌和抗真菌活性。。结果表明,在吡唑啉酮部分的N-2位上包含芳基或芳基磺酰基的双环吡唑酮对本研究中的所有微生物最有效。
