series of D-glucose-conjugated 4H-pyrano[2,3-d]pyrimidine–1H-1,2,3-triazole hybrid compounds 12a–g and 13a–g having piperidine and morpholine rings were synthesized by click chemistry between corresponding propargyl derivatives and azide of D-glucose using CuI@montmorillonite as a catalyst. Their inhibitory activities against E. coli MurA and S. aureus MurA and MurZ enzymes were examined. The morpholine
通过点击化学合成了一系列具有哌啶环和吗啉环的D-葡萄糖-共轭 4 H-吡喃并[2,3- d ]嘧啶-1 H -1,2,3-三唑杂化化合物12a-g和13a-g使用 CuI@montmorillonite 作为催化剂在相应的炔丙基衍生物和D-葡萄糖的叠氮化物之间。检测了它们对大肠杆菌MurA 和金黄色葡萄球菌MurA 和 MurZ 酶的抑制活性。3位的吗啉环与苯环上4位的乙氧基形成1,2,3-三唑13b成为该系列中针对所有三种酶(大肠杆菌MurA 以及金黄色葡萄球菌MurA 和 MurZ)最有效的抑制剂, IC 50值分别为 0.15 ± 0.05、1.02 ± 0.05 和 1.21 ± 0.05 μM。该化合物还对大肠杆菌和金黄色葡萄球菌表现出强烈的细菌生长抑制活性,MIC 值分别为 0.78 和 1.56 μg mL -1。对酶 1UAE 进行了诱导拟合对接和分子动力学模拟,以阐明13b对相应测试酶
