    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.

    摘要: The invention relates to new water-soluble agents which are effective as immunizing adjuvants. These adjuvant agents are the methyl, ethyl or propyl esters of 2-(2-acetamido-2-deoxy-3-O-D-glucopyranosyl)-D-propionyl-L-alanyl-D-isoglutamine and of 2-(2-acetamido-2-deoxy-3-O-D-glucopyranosyl)-D-propionyl-L-alanyl-D-glutamic acid, the 2-(2-acetamido-2-deoxy-3-O-D-glucopyranosyl)-D-propionyl-L-alanyl-D-(.alpha.-methylamide)-glutamic and 2-(2-acetamido-2-deoxy-3-O-D-glucopyranosyl)-D-propionyl-L-seryl-D-isoglutamine, the 2-(2-acetamido-2-deoxy-3-O-D-glucopyranosyl)-D-propionyl-L-seryl-D-glutamic acid and their derivatives. They are particularly useful to prepare adjuvant medicinal compositions, used for increasing the efficiency of vaccines.
