Title
(EN) POLYMER-PARTICLE LIGHT-CLEAVABLE CARRIER SYSTEMS FOR PHOTODYNAMIC THERAPY
(FR) SYSTÈMES PORTEURS PHOTOCLIVABLES À PARTICULES POLYMÈRES POUR THÉRAPIE PHOTODYNAMIQUE
Abstract
(EN)
The present invention generally relates to the formation, chemistry and application of biologically active compositions. More particularly, the present invention relates to certain dyes, specifically porphyrin and chlorin derivatives, in combination with inventive polymers, i.e. light-cleavable polymers, that can be used as photosensitizer compositions for a wide range of light irradiation treatments such as photodynamic therapy of cancer, infections and other diseases. The dye derivatives may either be adsorbed on, or incorporated in, or attached to specific polymers, which as well form part of the invention.

La présente invention porte d'une manière générale sur la formation, la chimie et l'application de compositions biologiquement actives. Plus particulièrement, la présente invention concerne certains colorants, spécifiquement des dérivés de porphyrine et de chlorine, en combinaison avec des polymères de l'invention, c'est-à-dire des polymères photoclivables, qui peuvent être utilisés en tant que compositions photosensibilisantes pour une large gamme de traitements par rayonnement lumineux tels qu'une thérapie photodynamique du cancer, des infections et d'autres maladies. Les dérivés de colorants peuvent être adsorbés ou incorporés dans, ou fixés à des polymères spécifiques, qui font également partie de l'invention.
