  Orally active cephalosporins. Part 3: synthesis, structure–activity relationships and oral absorption of novel C-3 heteroarylmethylthio cephalosporins

  摘要：

  A series of 7 beta-[(Z)-2-(2-aminothiazol-4-yl)-2-hydroxyiminoacetamido]-3-(heteroarylmethylthio)cephalosporins was designed, synthesized and evaluated for antibacterial activity and oral absorption in rats. Antibacterial activity was markedly influenced by the structure of the heteroaromatic ring moiety. Oral absorption was influenced by the heteroaromatic ring moiety as well as by the arrangement of heteroatoms. Among these compounds, FK041 (2o). having a 4-pyrazolylmethylthio moiety, showed potent antibacterial activity against both Gram-positive and Gram-negative bacteria including Haemophilus influenzae. Further, it showed higher oral absorption than CFDN. (C) 2001 Elsevier Science Ltd. All rights reserved.
