LIPOSOMAL DOXORUBICIN FORMULATION, METHOD FOR PRODUCING A LIPOSOMAL DOXORUBICIN FORMULATION AND USE OF A LIPOSOMAL DOXORUBICIN FORMULATION AS A MEDICAMENT
The present invention relates to a liposomal doxorubicin formulation, a method for producing a liposomal doxorubicin formulation and a liposomal doxorubicin formulation for use as a medicament, in particular for use in the treatment of cancer, uterine leiomyosarcoma and adnexal skin cancer.
PROLIPOSOMAL TESTOSTERONE UNDECANOATE FORMULATIONS
This invention relates to proliposomal powder dispersions of testosterone undecanoate (TU) and phospholipids, including dispersions of TU and palmitoylphosphatidylcholine (DPPC), wherein the weight/weight (w/w) ratio of TU:DPPC in the proliposomal powder dispersion is about 1:2; or TU and 1,2-dimyristoyl-sn-glycero-3-phosphocholine (DMPC), wherein the weight/weight (w/w) ratio of TU:DMPC in the proliposomal powder dispersion is about 1:3; or TU and a 1-myristoyl-2-palmitoyl-sn-glycero 3-phosphocholine (MPPC), wherein the weight/weight (w/w) ratio of TU:MPPC in the proliposomal powder dispersion is about 1:3.
Vesicles comprising epidermal growth factor and compositions thereof
The invention relates to vesicles comprising Epidermal Growth Factor (EGF), a cationic surfactant and cholesterol or derivatives thereof. The invention also discloses a procedure for their preparation, based on compressed fluid technology (CFs). The vesicles of the invention are useful in the manufacture of drugs and cosmetics and in tissue engineering.
Bufalin liposome, preparation method therefor and application thereof
The present invention provides a bufalin liposome comprising a liposome bilayer and bufalin. The liposome bilayer comprises phospholipid, sterol and polyethylene glycol (PEG)-derived compound. The liposome of the present invention can be used to treat cancer, especially a cancer chosen from liver cancer, lung cancer, ovarian cancer, prostate cancer, colon cancer, pancreas cancer, gastric cancer, and leukemia. The preparation method of the present invention is simple, and the bufalin liposome can increase an effect of antitumor, reduce a toxicity compared with bufalin monomer, and has wide applications.
Serial filtration to generate small cholesterol-containing liposomes
The present invention provides methods and systems for producing liposomes by filtration. The methods include passing a heated lipid suspension through a filter assembly comprising two or more filters connected in series, wherein an orifice is disposed between adjacent filters. The methods and systems can produce liposomes having an average diameter that is less than half the diameter of the filter pores. Further, the methods and systems can produce liposomes with <100 nm average diameter, even when the liposomes comprise at least 30% sterol.
Nanoparticles for chemotherapy, targeted therapy, photodynamic therapy, immunotherapy, and any combination thereof
Prodrugs containing lipid moieties attached to drug derivatives, such as anti-cancer drug derivatives, via linkers comprising disulfide groups are described. Also described are nanoparticles coated with a lipid layer containing the prodrugs, formulations comprising the nanoparticles, and the use of the nanoparticles in methods of treating diseases, such as cancer, alone or in combination with additional drug compounds, targeting agents, and/or immunotherapy agents, such as immunosuppression inhibitors that target the CTLA-4, PD-1/PD-L1, IDO, LAG-3, CCR-7 or other pathways, or multiple immunosuppression inhibitors targeting a combination of such pathways. Optionally, the nanoparticles can comprise a photosensitizer or a derivative thereof and can be used in methods involving photodynamic therapy. Synergistic therapeutic effects result from combinations of multiple modalities provided by the disclosed nanoparticles and/or nanoparticle formulations.
Stabilizing Camptothecin Pharmaceutical Compositions
Irinotecan phospholipid liposomes with improved storage stability are provided, with related methods of treatment and manufacture. The irinotecan liposomes can have reduced formation of lyso-phosphatidylcholine (lyso-PC) during storage, and prior to administration to a patient.
METHODS AND COMPOSITIONS FOR TREATING SYMPTOMS OF DISEASES RELATED TO IMBALANCE OF ESSENTIAL FATTY ACIDS
This invention relates to compositions containing combinations of a balanced phosphatidylcholine composition and one or more cannabinoids, a natural or synthetic derivative thereof, or a salt thereof, and kits containing such combinations and methods of using such combinations to treat subjects suffering from an imbalance of fatty acids and related diseases or disorders. This invention also relates to the synergistic effect of such combination therapies in humans.
Rice bran-lipids based formulation and process for preparation thereof for selective delivery of genes to cancer cells
The present invention relates to a formulation in which glycolipids and phospholipids, isolated from rice bran gum samples, were used in conjunction with gene carrying lipids to test its efficacy in delivering genes to cancer cells selectively. This formulation did not mediate efficient delivery of genes to non-cancerous cells, thus, showing potential use of this formulation to deliver anticancer therapeutics to cancer cells without eliciting treatment related toxicity to normal cells.
LIPOSOMAL APPARATUS AND MANUFACTURING METHODS
The present invention provides apparatus and processes for producing liposomes. By providing a buffer solution in a first reservoir, and a lipid solution in a second reservoir, continuously diluting the lipid solution with the buffer solution in a mixing chamber produces a liposome. The lipid solution preferably comprises an organic solvent, such as a lower alkanol.
