  N-(4-甲酰基-1-甲基-1H-吡唑-5-基)甲酰胺 在 palladium on activated charcoal 盐酸 、 氢气 、 苯甲醚 、 sodium iodide 作用下， 以 四氢呋喃 、 甲醇 、 二氯甲烷 、 N,N-二甲基甲酰胺 、 xylene 为溶剂， 反应 39.0h， 生成 7β-amino-3-[7-formyl-1-methyl-4,5,6,7-tetrahydro-2-(1H-pyrazolo[3,4-b]pyridinio)]methyl-3-cephem-4-carboxylate bistrifluoroacetate

  摘要：

  The synthesis and in vitro antibacterial activity of 7 beta-[(Z)-2-(2-aminothiazol-4-yl)-2-methoxyiminoacetamido]cephalosporins bearing N-mono or dialkyl and carbamoyl aminopyrazolium, and five- or six-membered rings fused to the 3-aminopyrazolium methyl groups at the 3-position, are described. Aminopyrazolium methyl cephalosporins (23e, f, i), with fused saturated and unsaturated rings were especially effective against Staphylococcus strains compared to 3-amino-2-methylpyrazolium methyl cephalosporin (1). Among the cephalosporins prepared in this work, 7 beta-[(Z)-2-(2-aminothiazol-4-yl)-2-methoxyiminoacetamido]-3-(4,5,6,7-tetrahydro-1-pyrazolo[1,5-a]pyrimidino)methyl-3-cephem-4-carboxylate (23f) showed a good balance of antibacterial activity against both Gram-positive bacteria including Staphylococcus aureus and Gram-negative bacteria including P. aeruginosa. An imidazopyrazolium group at the 3-position in, for example, cephalosporin (23i) was particularly effective for improving antibacterial activity against MRSA. (C) 1997 Elsevier Science Ltd.
