Abstract

L'invention concerne des particules qui ne sont pas supprimées rapidement de la circulation sanguine par les macrophages du système réticuloendothélial et qui peuvent être modifiées, afin de réaliser des fréquences variables de libération ou de cibler des cellules ou des organes spécifiques. Les particules possèdent un noyau d'un copolymère multibloc constitué par liaison covalente d'un composé multifonctionnel avec un ou plusieurs polymères hydrophobes et un ou plusieurs polymères hydrophiles et contiennent un matériau biologiquement actif. Le groupe hydroxyle terminal du polyalkyline glycol peut s'utiliser, afin d'effectuer la fixation covalente de molécules biologiquement actives sur la surface des particules, y compris des anticorps ciblés vers des cellules ou des organes spécifiques ou des molécules exerçant un effet sur la charge, le caractère lipophile ou hydrophile de la particule. La surface de la particule peut également être modifiée par fixation de polymères biodégradables présentant la même structure que ceux qui constituent le noyau des particules. La dimension typique des particules se situe entre 180 nm et 10.000 nm, de préférence entre 180 nm et 240 nm, bien que des particules peuvent également présenter la constitution décrite ci-dessus. Les particules peuvent comprendre des particules magnétiques ou des matériaux radioopaques s'utilisant en imagerie diagnostique, des molécules biologiquement actives conçues pour être dirigées vers un site ou des composés de ciblage des particules. Les particules possèdent une demi-vie prolongée dans le sang par rapport à des particules ne contenant pas des fractions de polyalkylène glycol sur leurs surfaces.
