A fusogenic liposome composition for delivering a liposome-entrapped compound into the cytoplasm of a target cell is described. The liposomes have an outer surface coating of chemically releasable hydrophilic polymer chains which shield hydrophobic polymers on the liposomes outer surface. Release of the hydrophilic polymer chains exposes the hydrophobic polymers for interaction with outer cell membranes of the target cells to promote fusion of the liposome with the target cells. Also disclosed is a method for using the composition to deliver a compound to target cells, and a method for selecting suitable hydrophobic polymers for use in the composition.

La présente invention concerne une composition de liposomes fusogènes permettant d'administrer un composé piègeant des liposomes dans le cytoplasme d'une cellule cible. Les liposomes comprennent un revêtement de surface externe de chaînes polymères hydrophiles à libération chimique protégeant des polymères hydrophobes sur la surface externe d'un liposome. La libération des chaînes de polymères hydrophiles met à nu les polymères hydrophobes en vue d'une interaction avec des membranes de cellules externes de cellules cible de façon à favoriser une fusion du liposome avec les cellules cible. La présente invention concerne, également, un procédé d'utilisation de la composition permettant d'administrer un composé aux cellules cible et un procédé de sélection des polymères hydrophobes adéquats de façon à les utiliser dans la composition.
