A series of polyhalo isophthalonitrile derivatives (3 and 4) that incorporate a variety of substituents at the 2-, 4-, 5- and/or 6-positions of the isophthalonitrile moieties have been designed and synthesized. These derivatives were evaluated for their antimicrobial activity against Staphylococcus aureus, Bacillus cereus (Gram-positive bacteria), Escherichia coli, Pseudomonas aeruginosa (Gram-negative
已经设计并合成了在聚邻苯二甲腈部分的2-,4-,5-和/或6-位上掺入各种取代基的一系列多卤代间苯二甲腈衍生物(3和4)。评价了这些衍生物对金黄色葡萄球菌,蜡状芽孢杆菌(革兰氏阳性菌),大肠杆菌,铜绿假单胞菌(革兰氏阴性菌)的抗菌活性。和白色念珠菌(Fungi)。化合物3和4对革兰氏阳性细菌和真菌的生长表现出较强的抑制作用,并且化合物3j的抗菌能力强(4-(苄氨基)-5-氯-2,6-二氟类似物,MIC [SA] = 0.5μg/ mL; MIC [BC] = 0.4μg/ mL; MIC [CA] = 0.5μg/ mL)与诺氟沙星和氟康唑接近,被确认为该系列中最有效的抗菌剂。还讨论了结构-活动关系的初步分析。
