Pyrimidine-1,3-oxazolidin-2-arylimino hybrids have been synthesized as a new class of antibacterial agents. The synthetic approach exploits a Cu(II)-catalyzed intramolecular halkoxyhalogenation of alkynyl ureas, followed by a Suzuki coupling reaction with 2,4-dimethoxypyrimidin-5-boronic acid. Biological screenings revealed that most of the compounds showed moderate to good activity against two Gram-positive
嘧啶-1,3-恶唑烷-2-芳基亚氨基杂化物已被合成为一类新的抗菌剂。合成方法利用 Cu(II) 催化的炔基脲分子内卤化卤化,然后与 2,4-二甲氧基嘧啶-5-硼酸进行 Suzuki 偶联反应。生物筛选显示,大多数化合物对两种革兰氏阳性菌(枯草芽孢杆菌、金黄色葡萄球菌)和三种革兰氏阴性菌(铜绿假单胞菌、伤寒沙门氏菌、肺炎克雷伯氏菌)显示出中等至良好的活性。在 Haloarcula marismortui 的 50S 核糖体单元的晶体结构中进行的分子对接研究表明,嘧啶-恶唑烷-2-芳基亚氨基杂化物 8c 和 8h 表现出高结合亲和力(-9.65 和 -10.74 kcal/mol),在与其良好的抗菌活性一致。
