摘要:
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.

摘要:
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.

This invention provides a method to prepare liposome-encapsulated bioactive agents, such as nucleic acids, comprising complexation of the bioactive agents to reverse micelles prior to forming liposomes, as well as methods of using the liposomes so formed and formulations to deliver nucleic acids to cells.

摘要:
This invention provides vehicles capable of delivering high concentrations of poorly hydrophilic/poorly lipophilic compounds to animals, by combining compounds having biocompatible hydrophobic domains with conjugates having both hydrophobic and hydrophilic regions. Such formulations are suitable for a number of uses in animals, particularly the administration thereto of high concentrations of therapeutically useful compound, without an undue level of side effects.
摘要:
Lipid-based carriers are provided herein that have a lamellar lipid component composed of an etherlipid and a complementarily shaped lipid. This novel combination of lipids allows for the incorporation of etherlipids in the carriers at higher concentrations than would otherwise be possible. Pharmaceutical compositions containing the carriers can be used therapeutically, for example, in the treatment of cancers.
