ABSTRACT:
The novel products are water-soluble oligomers, free of N-acetyl-glucosamine units, and of which the monomer elements include a group derived from muramic acid on which is fixed a chain of the peptide type including at least two aminoacyl residues, the first being selected from among: L-alanyl, L-arginyl, L-asparagyl, L-histidyl, L-hydroxyprolyl, L-isoleucyl, L-leucyl, L-methionyl, L-phenylalanyl, L-prolyl, L-seryl, L-threonyl, L-tryptophanyl, L-valyl, and the second aminoacyl is D-glutamyl or D-isoglutaminyl. They are useful for their immunoregulator properties and for the preparation of pharmaceutical compositions.
