An alternating copolymer comprising a backbone of residues of a maleic anhydride derivative and those of a compound containing vinylic unsaturation, which also comprises residues of an active compound containing a nucleophilic group, bound to the backbone by a residue of the nucleophilic group, including such copolymer comprising residues of an active compound containing alcohol, thiol or amine group. The chemical and biological propertieis of actives, such as protease inhibitors, neurotransmitter drugs, and other small molecule active drugs, are enhanced, and new applications enabled. Also, artefacts, including a solid medical implant device, dressing or scaffold or a fluid adhesive or medicinal composition comprising such a polymer, and a method of use of such polymer, including a method for the treatment or prophylaxis of wounds

L'invention concerne un copolymère alterné comprenant un squelette de résidus d'un dérivé d'anhydride maléique et d'un composé non saturé en vinyle, qui comprend également des résidus d'un composé actif contenant un groupe nucléophile, lié au squelette par un résidu du groupe nucléophile, ainsi qu'un un tel copolymère comprenant des résidus d'un composé actif contenant un groupe alcool, thiol ou amine. Les propriétés chimiques et biologiques de composants actifs, tels que des inhibiteurs de protéase, des médicaments neurotransmetteurs et d'autres médicaments actifs à petites molécules, sont renforcées, ce qui permet de nouvelles applications. En outre, l'invention concerne des artéfacts, notamment une prothèse médicale solide, des pansements ou structures, un adhésif liquide ou une composition médicinale comportant un tel polymère, ainsi qu'un procédé d'utilisation dudit polymère, y compris un procédé de traitement ou de prévention de blessures.
