  描述：

  benzhydryl 7β-(2-phenylacetamido)-3-(1,3,4-thiadiazol-2-yl)thio-3-cephem-4-carboxylate 在 三氟乙酸 作用下， 以 二氯甲烷 、 苯甲醚 为溶剂， 反应 1.0h， 以65%的产率得到(6R,7R)-8-Oxo-7-phenylacetylamino-3-([1,3,4]thiadiazol-2-ylsulfanyl)-5-thia-1-aza-bicyclo[4.2.0]oct-2-ene-2-carboxylic acid

  studies on anti-helicobacter pylori agents. part 2: new cephem derivatives

  摘要：

  The synthesis and optimization of the anti-Helicobacter pylori activity of a novel series of cephem derivatives are described. Introduction of thio-heterocyclic groups containing N- and S-atoms to the 3-position and phenyl or thienyl acetamido groups to the 7-position of the cephem nucleus dramatically improved the activity. From this series of derivatives, compound 13i was Found to have extremely potent in vitro anti-H. pylori activity, superior therapeutic efficacy compared to AMPC and CAM, no cross-resistance between CAM or MNZ and low potential for causing diarrhea due to instability to beta-lactamase.
