Oral Absorption of Cephalosporin Antibiotics. 3. Synthesis and Biological Properties of 7α-Methoxy-7β-(arylacetamido)-3-chloro-3-cephem-4-carboxylic Acids

A series of 7α-methoxy-7β-amido-3-chloro-3-cephem-4-carboxylic acids was prepared and evaluated for biological activity.When compared with the parent 7-non-methoxy analogues, these new 7α-methoxy-3-chloro cephalosporins displayed diminished antimicrobial
