A series of 1-pyrrole- and 1-indoleacetamido derivatives of 3-heteroaryl-substituted cephalosporins was prepared. The most active compound in the series was 7-[[2-(1-pyrryl)acetyl]amino]-3-[[(1-methyltetrazol-5-yl)thio]-methyl]-8-oxo-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylic acid (6), which showed comparable potency in vitro and in vivo to that of cefazolin, and, in addition, was more potent
制备了一系列3-杂芳基取代的头孢菌素的1-吡咯-和1-吲哚乙酰氨基衍生物。该系列中活性最高的化合物是7-[[[2-(1-吡啶基)乙酰基]氨基] -3-[[(1-甲基四唑-5-基)硫代]-甲基] -8-氧代5-硫杂-1-氮杂双环[4.2.0]辛-2-烯-2-羧酸(6),在体外和体内显示出与头孢唑林相当的效力,此外,它比头孢唑林对肠杆菌的效力更强。和Providencia stuartii。
