A series of novel 1,4-benzodioxan derivatives containing Schiff base are synthesized by the method of splicing active substructures. All compounds are assayed for antimicrobial activity. The preliminary results indicate that most of the products demonstrate higher antibacterial activity against Gram-negative bacteria strains than Gram-positive bacteria strains. Compounds 4d and 4m exhibit better antibacterial
通过拼接活性亚结构的方法,合成了一系列含有席夫碱的新型1,4-苯并二恶烷衍生物。测定所有化合物的抗微生物活性。初步结果表明,大多数产品显示出比革兰氏阳性菌更高的对革兰氏阴性菌的抗菌活性。化合物4d和4m分别对大肠杆菌表现出更好的抗菌活性(MIC = 0.78和0.17μg/ mL)。化合物4g对铜绿假单胞菌显示出更好的抗菌活性(MIC = 0.78μg/ mL)。选择了11种常见的抗菌靶标用于目标化合物的分子对接。结果表明,所有目标化合物均具有与酪氨酸-tRNA合成酶最强的结合能(-CDOCKER_INTERACTION_ENERGY,kcal / mol:47.1486和47.3776)。因此,推测目标化合物可以用作新型酪氨酸-tRNA合成酶抑制剂。
