A liposome including a fusogenic liposome, a linking moiety and a targeting moiety. The fusogenic liposome is a lipid bilayer encapsulating contents. The linking moiety is electrostatically bound to the lipid bilayer, and the targeting moiety is covalently bound to the linking moiety. The liposome may also include a stabilizing moiety interposed between the linking and targeting moieties, and covalently bound to both. Alternatively, the stabilizing and targeting moieties may be covalently bound to separate linking moieties, the linking moieties being electrostatically bound to the lipid bilayer.

Modular targeted liposomal delivery system

Peptide-lipid conjugates are incorporated into liposomes so as to selectively destabilize the liposomes in the vicinity of target peptidase-secreting cells, and hence, to deliver the liposomes to the vicinity of the target cells, or directly into the cells. The liposomes can thus be used to treat mammals for diseases, disorders or conditions, e.g., tumors, microbial infection and inflammations, characterized by the occurrence of peptidase-secreting cells.
