    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.
