Conjugates consisting of a polymeric carrier constituted by 30 to 3,000 monomer units linked to form a polymeric chain, composed of
a. 60 to 99 % of N -(2-hydroxypropyl)methacrylamide units
b. 1 to 25 % of units of methacryloylated hydrazones of ±-amino acids, µ-amino acids, aromatic amino acids, or oligopeptides terminated with a molecule of an anthracycline cancerostatic
c. 0.5 to 15 % of units ofmethacryloylated ±-amino acids, µ-amino acids, aromatic amino acids or oligopeptides or their sodium salts, and optionally
d. 0.5 to 10 % of units of methacryloylated hydrazides of ±-amino acids, µ-amino acids, aromatic amino acids or oligopeptides
e. 0.5 to 5 % of methacryloylated ±-amino acids, µ-amino acids or oligopeptides terminated by a molecule of immunoglobulin or of a specific monoclonal or polyclonal antibody,
of the below given general formula, the individual structural units being disposed in a random manner in the chain and where x ranges from 20 to 3,000, a is from 1 to 750, b and c are each from 1 to 450, d ranges from 1 to 150, X is a residue of an amino acid or oligopeptide chosen from the following series: Gly, Ala, Leu, GlyGly, GlyLeuGly, GlyPheGly, GlyPheLeuGly, ²-alanine, ³-amino butyric acid, µ-amino caproic acid (AKap), p-amino benzoic acid (AB), and S is an antibody selected from the following series: ³-globulin for i.v. administrations, autologous antibodies, antibodies anti-17-1A, anti-CA 15-3 and the like, linked to the polymeric chain by the marked structure. |
