A series of cephalosporins, 2-isocephems, and 2-oxaisocephems with C-3' catechol-containing (pyridinium-4-thio)methyl groups and 2-isocephems with C-7 catechol related aromatics have been prepared and evaluated for antimicrobial activity. It turns out that these compounds have highly potent activity against Gram-negative bacteria, especially resistant pathogens such as Pseudomonas aeruginosa. The most
制备了一系列具有C-3'邻苯二酚的(4-吡啶鎓吡啶)甲基的头孢菌素,2-isophephems和2-oxaisocephephe和具有C-7-catechol相关芳香族化合物的2-isophephes,并进行了抗菌活性评估。事实证明,这些化合物对革兰氏阴性菌,特别是铜绿假单胞菌等耐药病原体具有很强的活性。该系列中活性最高的化合物是(6S,7S)-7- [2-(2-氨基噻唑-4-基)-2-[(Z)-[(1,5-二羟基-4-吡啶idon-2 -(基)甲氧基]亚氨基]乙酰胺基] -3-[[[((4-甲基-5-羧甲基)噻唑-2-基]硫代]甲基] -8-氧代-1-氮杂-4-硫代双环[4.2.0 ]辛-2-烯-2-羧酸,对临床分离的P,铜绿假单胞菌和鲍曼不动杆菌均表现出强大的体外活性,而鲍曼不动杆菌也对许多抗感染药具有耐药性,
