)-4-methyl-1H-imidazol-2-yl)thio)-N-(4-((benzyl)oxy)phenyl) acetamide derivatives. Antimicrobial activities of all the imidazole derivatives have been examined against Gram-positive and Gram-negative bacteria and results showed that the conjugates have appreciable antibacterial activity. Besides, several analogous were evaluated for their in vitro antiresistant bacterial strains such as Extended-spectrum
在本研究中,我们设计并合成了 2-((5-acetyl-1-(phenyl)-4-methyl-1 H -imidazol-2-yl)thio) -N- (4-((benzyl)oxy)苯基)乙酰胺衍生物。已经检测了所有咪唑衍生物对革兰氏阳性和革兰氏阴性细菌的抗菌活性,结果表明缀合物具有可观的抗菌活性。此外,还评估了几种类似物的体外抗耐药菌株,如超广谱β-内酰胺酶(ESBL)、耐万古霉素肠球菌(VRE)和耐甲氧西林金黄色葡萄球菌(MRSA)。SAR 显示 12l 化合物具有抗所有细菌菌株以及 ESBL、VRE 和 MRSA 菌株的效力。对含有金黄色葡萄球菌二氢蝶酸合酶 (saDHPS) 蛋白(PDB ID:6CLV)的所有合成化合物进行了 Lipinski 的五法则和 ADME 研究,并发现了缀合物的标准药物相似特性。此外,配体与蛋白质研究的结合模式已经通过分子对接进行了检查,结果非常有希
