  The synthesis and in vitro and in vivo activities of a series of 7-sulfonylacetamido-3-cephem-4-carboxylic acids with acetoxymethyl or heterocyclic thiomethyl substituents at the 3 position are described. Lengthening the alkyl chain attached to the sulfonyl group increased gram-positive activity but the effect on gram-negative activity was variable. Other structural changes on the 7-acyl side chain

  描述了一系列在3位带有乙酰氧基甲基或杂环硫代甲基取代基的7-磺酰基乙酰氨基-3-cephem-4-羧酸的合成以及体外和体内活性。延长连接至磺酰基的烷基链可提高革兰氏阳性活性，但对革兰氏阴性活性的影响却是可变的。7-酰基侧链上的其他结构变化仅导致体外活性的微小变化。除了丁基磺酰基衍生物的保护作用不如体外活性所预测的那样，在感染小鼠中的保护效果通常与体外活性相当。用3-杂环硫代甲基取代3-乙酰氧基甲基导致体外和体内活性的总体提高。

  Cephalosporins with new aminobenzimidazole and aminoimidazoline heterocycles at C-7 have been synthesized starting with versatile C-7 isocyanide dihalide synthons. The aminobenzimidazoles have a broad spectrum of antibacterial activity, including Gram-positive and Gram-negative organisms, but possess limited beta-lactamase stability. In contrast, the aminoimidazolines have a narrow spectrum of antibacterial activity, limited to Gram-negative strains only, but possess outstanding beta-lactamase stability. Structure-activity relationships are discussed in terms of their dependence on the pK(a) of the C-7 amino heterocycle, basic C-7 residues giving cephalosporins with exceptional beta-lactamase stability.
