activities of previously synthesized 2-(substituted)oxazolo[4,5-b]pyridine derivatives toward six bacteria strains and twelve related drug-resistant isolates, and one fungus strain and two related drug-resistant isolates were investigated via the microdilution method. P6 (2-(4-trifluoromethylphenyl)oxazolo[4,5-b]pyridine) and P7 (2-(4-trifluoromethoxyphenyl)oxazolo[4,5-b]pyridine) showed better activity against
本研究考察了先前合成的2-(取代)恶唑并[4,5- b ]吡啶衍生物对6种细菌菌株和12种相关耐药菌株以及1种真菌菌株和2种相关耐药菌株的抗菌活性。通过微量稀释法。P6(2-(4-三氟甲基苯基)恶唑并[4,5- b ]吡啶)和P7(2-(4-三氟甲氧基苯基)恶唑并[4,5- b ]吡啶)对粪肠球菌分离物和大肠杆菌表现出更好的活性。大肠杆菌分离物比氨苄青霉素具有 16 μg mL -1的 MIC 。此外,P5 (2-(4-甲氧基苯基)恶唑并[4,5-b ]吡啶)和P6对铜绿假单胞菌显示出与庆大霉素相当的活性,MIC为16 μg mL -1,而P7显示出比庆大霉素更好的活性,MIC为8 μg mL -1。这些化合物通常表现出良好至强的抗微生物活性。使用 DNA 促旋酶对化合物进行分子对接和分子动力学模拟,并评估相互作用。这些化合物在 DNA 促旋酶 ATP 结合位点显示重叠,具有相似的蛋白质-配体相互作用。apo
