摘要: 通过2-取代1,3,4-二唑-5-硫醇1a-1f和头孢菌素母体7-ACA反应,制得头孢菌素中间体2a_2f,用氨噻唑肟活性酯3和1-芳基-5-甲基-1H-1,2,3-三唑-4-甲酰氯4a_4e分别和头孢菌素中间体缩合,制得头孢菌素新衍生物5a_5b和6a_6h.新化合物的结构经1HNMR,IR及MS确认.初步体外抗菌结果表明,头孢菌素5a_5b对革兰氏阳性和阴性菌有显著抑制活性,而6a_6h对其则显示出中等程度的抑制活性

Abstract: New cephalosporin derivatives5a_5b and6a_6h were prepared by condensation of2a_2f with aminothiazoleoxime active ester3 and1-ryl-5-methyl1-H-1,2,3 triazol3-formyl chloride4a_4e, respectively.The intermediate2a_2f were synthesized by reaction of2-substituted-1,3,4 oxadiazol-5-thiols1a-1f with 7-ACA.The structures of the compounds synthesized were confirmed by IR, 1H NMRand MSspectra.The preliminary results of antibacterial activities revealed that5a_5b showed significant antibacterial activities against both Gram-positive and Gram-negative bacteria, and6a_6h had moderate antibacterial activities against these bacteria

Key words: Cephalosporin, Semisynthesis, Antibacterial activity, Centrifugal-TLC
