A series of N,N-Bis(2-hydroxylbenzyl)-1,2-ethanediamine derivatives and its schiff bases were synthesized, characterized and screened for in vitro antimicrobial activity against Staphylococcus aureus, Pseudomonas aeruginosa and Salmonella enterica. Result indicated that the ethylenediamine derivatives, N,N-Bis(2-hydroxy-5-bromobenzyl)-1,2- ethanediamine (21), and N,N-Bis(2-hydroxy-5-chlorobenzyl)-1,2-ethanediamine (22) showed the most favorable antimicrobial activity exhibiting LC50 of 11.6 and 8.79 μM against S.enterica, 86 and 138 μM against P. aeruginosa, and 140 and 287 μM against S. aureus, respectively. These compounds displayed highest level of resistance with S. aureus. Thus, the high level of activity seen with the compounds (21, 22) suggests that these compounds could serve as the leads for development of novel synthetic compounds with enhanced antimicrobial activity.
合成了一系列N,N-双(2-羟基苯甲基)-1,2-乙二胺衍生物及其希夫碱,对其进行了表征,并筛选评估了其对金黄色葡萄球菌、铜绿假单胞菌和沙门氏菌的体外抗菌活性。结果显示,乙二胺衍生物N,N-双(2-羟基-5-溴苯甲基)-1,2-乙二胺(21)和N,N-双(2-羟基-5-氯苯甲基)-1,2-乙二胺(22)表现出最优的抗菌活性,对沙门氏菌的LC50分别为11.6和8.79 μM,对铜绿假单胞菌的LC50为86和138 μM,对金黄色葡萄球菌的LC50为140和287 μM。这些化合物对金黄色葡萄球菌表现出最高的耐药水平。因此,化合物(21, 22)所展现的高活性表明这些化合物可能作为开发新型合成化合物以增强抗菌活性的先导化合物。
