The invention relates to conjugates in which a sterol is functionalized by an ether bond with a water-soluble polymer to which a guiding ligand is bound. These conjugates improve the physico-chemical and delivery properties of their carrying vesicles, making these more stable, homogeneous and effective. A method for their preparation, a pharmaceutical composition containing said liposomes, and their therapeutic use are described as well.
