USPTO Abstract

C<6><3>-Amide derivatives of 34-de(acetylglucosaminyl) -34-deoxy-teicoplanin wherein the amide moiety is derived from a di- or poly-amine. The derivatives are prepared by reacting 34-de(acetylglucosaminyl)- 34-deoxy-teicoplanins with an active esters forming reagent such as chloroacetonitrile and then contacting said active esters with the appropriate di- or polyamine. The amide derivatives which are active against Gram-positive microorganisms, in particular against Group A Streptococci were found to be active also against bacteria which are resistant to glycopeptide antibiotics.
