Abstract

La présente invention a pour objet des polyacétals biocompatibles et biodégradables, leurs procédés de fabrication et des méthodes de traitement des mammifères par l'administration desdits polyacétals. Une des méthodes de formation des polyacétals biocompatibles et biodégradables consiste à combiner un agent d'oxydation spécifique du glycol avec un polysaccharide afin de former une aldéhyde intermédiaire que l'on combine avec un agent de réduction pour former le polyacétal biocompatible et biodégradable. Les polyacétals biocompatibles et biodégradables qui en résultent peuvent être modifiés chimiquement afin d'inclure des parties hydrophiles supplémentaires. Une des méthodes de traitement des mammifères consiste à administrer le polyacétal biocompatible et biodégradable dans lequel on peut disposer des composés biologiquement actifs ou des marqueurs de diagnostic.
