Abstract

Patente de Invenção:<B>"PARTìCULAS DE TRANSFECçãO"<D>. Partículas de transfecção para liberação de ácido nucleico em células eucarióticas superiores in vitro e in vivo compreendem uma ou mais moléculas de ácido nucleico condensadas por moléculas catiónicas orgânicas. As partículas discretas e estáveis são obtidas por compleição das moléculas de ácido nucleico com idênticas ou diferentes moléculas precursoras catiónicas orgânicas sem reticulação das moléculas de ácido nucleico, e covalentemente ligando as moléculas precursoras entre si no ácido nucleico padrão. Para o alvejamento celular específico, as partículas podem transportar moléculas de alvejamento, por exemplo açúcares. As moléculas precursoras catiónicas preferidas são os detergentes lipofílicos que são ligados para formar lipídeos. As partículas contêm preferivelmente apens uma molécula de ácido nucleico que torna-as úteis para a terapia de gene e para a liberação de grandes moléculas de DNA.
