Abstract

Abstract Translated from French Les N-polyosyl-polypeptides de formule (Oside-Z′-CH₂-NH-) n P′ dans laquelle P′ est le radical n-valent d'un polypeptide P, P′ étant autre que le radical monovalent de l'hémoglobine, Oside-Z′ est le radical d'un polysaccharide Oside-Z privé de son extrémité aldéhydique réductrice, possèdent une pharmacocinétique améliorée par rapport au polypeptide P. Ils sont préparés par réaction d'un peptide P avec la forme aldéhydique de Oside-Z en passant par les poly-bases de Schiff intermédiaires (Oside-Z′-CH=N) n P′ The N-polyosyl-polypeptides of formula (Oside-Z′-CH₂-NH-) n P ′ in which P ′ is the n-valent radical of a P polypeptide, P ′ being other than the monovalent radical of hemoglobin, Oside-Z ′ is the radical of an Oside-Z polysaccharide deprived of its reducing aldehyde end, have an improved pharmacokinetics compared to the polypeptide P. They are prepared by reaction of a peptide P with the aldehyde form of Oside-Z via the intermediate poly-bases of Schiff (Oside-Z′-CH = N) n P ′
