    摘要: 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.

    摘要: A polymer of peptidic type formed by a chain formed from aminoacyl residues preferably derived of at least one of the amino-acid residues selected from the class consisting of .alpha.,.gamma.-diaminobutyric acid, ornithine, lysine, homo-lysine, of which the lateral amino functions portionally carry peptide branches of which the aminoacyl residues are preferably derived of those selected from the class consisting of alanine, glycine, .alpha.-aminobutyric acid, valine, leucine and proline, the above-said peptide polymer having an average molecular weight comprised between about 50,000 and 250,000, and to which are bound covalently, muramyl-peptide units of which the two first aminoacid residues bound to the muramyl group are stereoisomers of the D series, the second aminoacid residue having the structure of the glutamic acid.This product is useful as anti-infectious agent.
