摘要: 利用1-芳基-5-甲基-1H-1,2,3-连三唑-4-甲酰氯、苯并三唑-1-乙酰氯以及5-甲基异(哑心)唑-3-甲酰氯在低温、丙酮-水条件下,分别同7-ACA、7-ADCA和7-ADCT反应,制得13种头孢菌素衍生物3a-3i、6a-6b和9a-9b,所有化合物经葡萄糖聚糖凝胶柱层析和离心薄层层析反复精制得纯品,新化合物结构经元素分析、IR、1HNMR和FAB-MS确认.其中代表物显示出强的抗菌活性.

Abstract: Nine new 7 β-(1-aryl-5-methyl-1H-1,2,3-triazolyl-4-formamido)cephalosporins 3a-3j were synthesized by acylation of 7 β-amino group of 7-ACA, 7-ADCAand 7-ACT, with 1-aryl-5 methyl-1H-1,2,3-triazolyl-4 formyl chloride 2a-2c. Two new 7 β-(1,2,3-benzotriazolyl-1-acetamido) cephalosporins 6a 6b and two new 7 β-(5-methyl isoxazolyl-3-formamido) cephalosporins 9a-9b were obtained with the same acid choride. Isolation and purification of the new compounds were fulfilled with Sephadex LH-20 column chromatography and centrifugal TLCtechnique. The structure of the compounds were confirmed by elementary analysis, IR, 1HNMRand FAB MS, some of them showed a significant antibacterial activity.

Key words: Cephalosporins, Vicinal triazole, Semisynthesis, Antibacterial activity, Centrifugal TLC
