  为了提高cefozopran (CZOP) 对耐甲氧西林金黄色葡萄球菌 (MRSA) 的抗菌活性，我们开始了化学修饰，引入一个2-(5-氨基-1, 2, 4-噻二唑-3-基)-2(Z)-羟亚氨基乙酰基团在C-7位，以及一个3位或6位取代的咪唑[1, 2-b]吡啶鎓或5位取代的咪唑[1, 2-a]吡啶鎓基团在C-3'位。尽管这种方法成功地将CZOP对MRSA的抗性提高了两到八倍，但对包括铜绿假单胞菌在内的革兰氏阴性菌的活性略有下降。在这些新衍生物中，3-(6-氨基咪唑[1, 2-b]吡啶鎓-1-基)甲基-7β-[2-(5-氨基-1, 2, 4-噻二唑-3-基)-2(Z)-羟亚氨基乙酰氨基]-3-头孢烯-4-羧酸酯(44a)表现出了对MRSA和革兰氏阴性菌的活性之间的优良平衡。

  In an effort to discover a novel cefozopran (CZOP) derivative having excellent antibacterial activity against methicillin-resistant Staphylococcus aureus (MRSA), we performed chemical modification of the alkoxyimino moiety and imidazo[1, 2-b]pyridazinium group of CZOP. Among the prepared compounds, the cyclopentyloxyimino derivative 7β-[2-(5-amino-1, 2, 4-thiadiazol-3-yl)-2(Z)-cyclopentyloxyiminoacetamido]-3-(3, 6-diaminoimidazo[1, 2-b]pyridazinium-l-yl)methyl-3-cephem-4-carboxylate (20g) showed the most potent anti-MRSA activity, reflecting its high affinity (IC50=1.6 μg/ml) for penicillin binding protein 2' (PBP2'), although its anti-MRSA activity was slightly inferior to that of vancomycin (VCM). In experimental systemic infection in mice, however, 20g showed activity comparable to that of VCM against MRSA. In addition, 20g showed activity similar or slightly inferior to that of CZOP against Pseudomonas aeruginosa both in vitro and in vivo. Considering its favorable antibacterial activity profile, 20g was considered to be the most promising CZOP derivative for further studies.

  为了发现一种对耐甲氧西林金黄色葡萄球菌（MRSA）具有出色抗菌活性、新颖的头孢唑普兰（CZOP）衍生物，我们对CZOP的烷氧亚氨基部分和咪唑并[1,2-b]哒嗪鎓基团进行了化学修饰。在制备的化合物中，环戊氧亚氨基衍生物7β-[2-(5-氨基-1,2,4-噻二唑-3-基)-2(Z)-环戊氧亚氨基乙酰胺基]-3-(3,6-二氨基咪唑并[1,2-b]哒嗪鎓-1-基)甲基-3-头孢烯-4-羧酸酯（20g）表现出最强的抗MRSA活性，反映其对青霉素结合蛋白2'（PBP2'）的高亲和力（IC50=1.6μg/ml），尽管其抗MRSA活性略逊于万古霉素（VCM）。然而，在小鼠实验性系统感染中，20g对MRSA表现出与VCM相当的活性。此外，20g无论在体外还是体内，对铜绿假单胞菌（Pseudomonas aeruginosa）的活性与CZOP相似或略逊。综合其良好的抗菌活性特征，20g被认为是最有希望的CZOP衍生物，值得进一步研究。

  In order to improve the antibacterial activity of cefozopran (CZOP) against methicillin-resistant Staphylococcus aureus (MRSA), we initiated chemical modification to introduce a 2-(5-amino-1, 2, 4-thiadiazol-3-yl)-2(Z)-hydroxyimino acetyl group at the C-7 position and a 3- or 6-substituted imidazo[1, 2-b]pyridazinium or 5-substituted imidazo[1, 2-a]pyridmium group at the C-3' position. Although this approach successfully enhanced the anti-MRSA activity of CZOP two to eight times, a slight decrease in the activity against Gram-negative bacteria including Pseudomonas aeruginosa was involved. Among the novel derivatives, 3-(6-aminoimidazo[1, 2-b]pyridazinium-1-yl)methyl-7β-[2-(5-amino-1, 2, 4-thiadiazol-3-yl)-2(Z)-hydroxyiminoacetamido]-3-cephem-4-carboxylate (44a) showed an excellent balance of activity against MRSA and Gram-negative bacteria.
