Abstract[English]
A water soluble polymeric compound is disclosed. The compound comprises: i) one or more antineoplastic agents; ii) a heteroalkylene backbone comprising negatively charged groups at physiological pH; iii) one or more linear or branched linkers comprising a self-immolative group and an optional spacer group, the linker linking each antineoplastic agent to the heteroalkylene backbone; and iv) a reactive group capable of forming a covalent bond to a targeting moiety. The water soluble polymeric compound finds utility in a number of applications, including use as therapeutic agents for various treatment methods.[French]
Un composé polymère soluble dans l'eau est divulgué. Le composé comprend : i) un ou plusieurs agents antinéoplasiques ; ii) un squelette hétéroalkylène comprenant des groupes chargés négativement à un pH physiologique ; iii) un ou plusieurs lieurs linéaires ou ramifiés comprenant un groupe auto-immolable et un groupe espaceur facultatif, le lieur liant chaque agent antinéoplasique au squelette hétéroalkylène ; et iv) un groupe réactif permettant de former une liaison covalente à une fraction de ciblage. Le composé polymère soluble dans l'eau trouve une utilité dans un certain nombre d'applications, comprenant l'utilisation en tant qu'agents thérapeutiques pour divers procédés de traitement.
