The N-polyosyl polypeptides of formula (Oside-Z'-CH2-NH-)nP' in which P' is the n-valent radical of a polypeptide P, P' being other than the monovalent haemoglobin radical, Oside-Z' is the radical of an Oside-Z polysaccharide deprived of its reducing aldehyde end, have pharmacokinetics which are improved in relation to the polypeptide P. They are prepared by reacting a peptide P with the aldehyde form of Oside-Z via the intermediate Schiff polybases (Oside-Z'-CH=N)nP'. |
