title: Synthesis and antibacterial activity of new cephalosporines containing a pyrrole ring in the N-acyl chain.
abstract: Nine new cephalosporines containing a pyrrole ring in the N-acyl chain have been synthesized by the N-acylation of 7-ACA or of its 3-analogues via the acid chlorides of substituted 2-pyrrole-carboxylic, -acetic or -propionic acids. H1 NMR and IR data confirming the structure are presented. Preliminary microbiological tests in vitro show significant antibacterial activity, compared with that of cefalexin. Some common structure-activity relationships have been observed.
