  • Glycopeptides and method for preparing same
    Patent number: 4395399
    Abstract: Glycopeptides according to the present invention have the formula: ##STR1## wherein n=1 or 2; R is a residue of an aminoacid or linear peptides built of 2 to 5 amino acid residues.These compounds are prepared by the method involving condensation of unblocked muramyl-containing N-acetylamino-sugars of the formula: ##STR2## wherein n=1 or 2, with blocked aminoacids or peptides. The method of this invention makes it possible to produce synthetic glycopeptides manifesting a biological activity. These compounds possess an antitumor and adjuvant activity.
