Self forming, thermodynamically stable liposomes and their applications
View Patent ↗Certain diacylglycerol-polyethyleneglycol (DAG-PEG) lipids are especially useful for forming thermodynamically stable liposomes. Such liposomes are useful for a variety of purposes, including the delivery of therapeutic agents.
1. A composition for the preparation of a liposome, said composition comprising:
an active compound, where the active compound is a protein, peptide, nucleic acid, agent for treating a neoplasm, agent for treating inflammation, agent for treating an infection, agent for treating a gasterointestinal disease, agent for treating an immunological disease, agent for treating a skin diseases or an eye disease, agent use in diagnosing disease, nutrient, agent for treating a blood disease, agent for treating a metabolic disease, agent for treating a cardiovascular disease, agent for treating a renal disease, agent for treating a genitourinary disease, agent for treating a respiratory disease or agent for treating a central nervous system disease; and
one or more lipids selected from the group consisting of PEG-12 glycerol dioleate (GDO), PEG-12 glycerol dimyristate (GDM), PEG-23 glycerol dipalmitate (GDP), PEG-12 glycerol distearate (GDS), and PEG-23 GDS, where the number after “PEG” indicates the numbers of C 2 H 4 O subunits in the PEG chain.
