biological evaluation of a series of 7-[2-(2-aminothiazol-4-yl)-2-(Z)-[(cyclopentyloxy)imino]acetamido] optically active 2-oxaisocephems, substituted at the 3-position with [(N-alkylpyridinium-4'-yl)thio]methyl groups, are described. The resulting family of parenteral compounds displays a broad spectrum of in vitro antibacterial activity. These compounds exhibit increased activity against Gram-positive organisms
在3位取代的7- [2-(2-(2-氨基噻唑-4-基)-2-(Z)-[(环戊氧基)亚氨基]乙酰胺基]旋光2-氧杂松香的制备及生物学评价描述了具有[(N-烷基吡啶-4'-基)硫代]甲基的化合物。所得的肠胃外化合物家族显示出广谱的体外抗菌活性。这些化合物对革兰氏阳性生物体(包括耐甲氧西林的金黄色葡萄球菌和粪肠球菌)表现出增强的活性,它们对大多数头孢菌素具有抗性,革兰氏阴性活性的水平与第三代抗生素相似。与参考化合物相比,本研究中新型抗菌剂对革兰氏阳性菌和革兰氏阴性菌均具有出色的体内功效。
