Abstract
Abstract The invention relates to novel compounds of the muramyl-peptide type and to their uses. The muramyl-peptides according to the invention comprise at least two aminoacyl residues in the peptide chain, the second of these aminoacyl residues being D-glutamyl, and they are characterized in that the nitrogen of the first amino-acyl, and forming part of the pepetide linkage connecting the muramyl group to the peptide residue, is substituted by an alkyl group. These compounds are useful notably for the preparation of pharmaceutical compositions, in particular by reason of their regulatory properties on the immune responses of the organism.
