Abstract
Nouveaux produits conjugués de doxorubicine et de ses analogues avec un polymère anionique. Le polymère anionique utilisé est un copolymère de pyranne (cyclopolymère 1,2 régulièrement alterné d'éther divinylique et d'anhydride maléique, également connu sous l'appellation 'DVE-MA') sous sa forme polycarboxylate. La liaison des agents antitumeurs au polymère est effectuée par une liaison ester obtenue par substitution nucléophile sur leurs dérivés 14-bromo. Etant donné qu'ils sont libérés lentement 'in vivo', les nouveaux produits conjugués améliorent considérablement le comportement pharmacocinétique et l'efficacité thérapeutique des agents antitumeurs.New conjugated products of doxorubicin and its analogs with an anionic polymer. The anionic polymer used is a copolymer of pyran (cyclopolymer 1,2 regularly alternated with divinyl ether and maleic anhydride, also known under the name 'DVE-MA') in its polycarboxylate form. The binding of antitumor agents to the polymer is carried out by an ester bond obtained by nucleophilic substitution on their 14-bromo derivatives. Since they are released slowly 'in vivo', the new conjugate products considerably improve the pharmacokinetic behavior and the therapeutic efficacy of anti-tumor agents.
