Abstract

Patente de Invenção: "LIPOLìMERO NEUTRO E COMPOSIçõES DE LIPOSSOMA CONTENDO O MESMO". Lipossomas contendo lipopolímeros neutros substituídos por PEG fornecem tempos de circulação similares os lipossomas que incorporam fosfolipídeos substituídos por PEG negativamente carregados convencionais. O uso dos lipopolímeros não carregados pode também apresentar vantagens em termos de interações com as superfícies celulares e vazamento reduzido de substâncias carregadas, particularmente drogas catiónicas, dos lipossomas. Os lipopolímeros são da fórmula (1) em que cada um de R^ 1^ e R^ 2^ é uma cadeia de alquila ou alquenila tendo entre cerca de 8 a cerca de 24 átomos de carbono; n é de cerca de 10 a cerca de 300, Z é selecionado do grupo que consiste em hidróxi, alcóxi, benzilóxi, éster carboxílico, éster suifónico, carbamato de alquila ou de arila, amino e alquilamino e a ligação L é selecionada do grupo que consiste em (i) -X-(C=O)-Y-CH~ 2~-, (ii) X-(C=O)- e (iii) -X-CH~ 2~-, em que X e Y são independentemente selecionados de oxigênio, NH, e uma ligação direta.
