METHOD FOR PRODUCING LIPOSOME AND APPARATUS FOR PRODUCING LIPOSOME
Disclosed herein are a method for producing a liposome which is capable of reducing the facility costs and also capable of rapid desolvation, and an apparatus for producing a liposome which is for use in the above-mentioned method. Provided is a method for producing a liposome, including a stirring step of stirring a mixed liquid containing an oil phase in which at least one lipid is dissolved in an organic solvent and a water phase, and an evaporating step of evaporating an organic solvent from the mixed liquid, in which the condensed organic solvent is removed by passing a gas having a temperature not higher than the dew point of the solvent in the evaporating step.
Cochleates made with soy phosphatidylserine
Unpurified or low pure soy phosphatidylserine is used to make cochleates. The cochleates contain about 40-74% soy phosphatidylserine, a multivalent cation and a biological active. A preferred cochleate contains the antifungal agent amphotericin B.
Internal structured self assembling liposomes
The specification relates to an internal structured self assembled liposome (ISSAL), containing a nuclear core molecule or complex including a first affinity enhancing molecule; and a phospholipid-affinity enhancing complex having a phospholipid coupled to second affinity enhancing molecule, wherein the second affinity enhancing molecule couples to the first affinity enhancing molecule. The ISSAL's can be used in, for example and without limitation, the field of drug delivery, vaccination, imaging contrast agents, and nanotechnology, in which liposomes of ordered, self-assembling structure are employed to deliver soluble or insoluble molecules to any sub-cellular address.
TAILORED HYPOIMMUNE NANOVESICULAR DELIVERY SYSTEMS FOR CANCER TUMORS, HEREDITARY AND INFECTIOUS DISEASES
Hypoimmunogenic induced pluripotent stem cell (iPSC)-derived biomimetic nanovesicles (Hypo-BioNVs) or Hypo-exosomes including tailored chimeric antigen receptor (CARs) which can recognize target biomarkers through an antibody fragment scFV region, bifunctional or ByTE antibodies, by a viral epitope recognition receptor (VERR), V.sub.HH nanobody, Variable New Antigen Receptor (V.sub.NAR), engineered TCR, or by any single heavy chain IgG fragment from which a variable region can be engineered. A method of making Hypo-BioNVs. A method of treating an individual with cancer, by administering the Hypo-BioNVs to an individual, targeting cancer cells, and treating the cancer. Hypo-BioNVs including tailored CARs which can recognize target biomarkers through a VERR including viral receptors of an oncolytic virus. A method of treating an individual with cancer, by administering Hypo-BioNVs including CAR receptors having a VERR, V.sub.HH nanobody, V.sub.NAR, engineered TCR, or by any single heavy chain IgG fragment from which a variable region can be engineered with viral receptors of an oncolytic virus to an individual, targeting cancer cells, and treating the cancer. A method of targeting cells in an individual, by administering the Hypo-BioNVs to an individual, and targeting cells to be destroyed or treated for cancer tumors (both liquid and solid), infectious disease, hereditary conditions, autoimmune disease, or metabolic disorders.
SUSTAINED TIMOLOL MALEATE DELIVERY FROM LIPOSOMES FOR GLAUCOMA THERAPY AND OCCULAR HYPERTENSION
Various embodiments relate to the field of liposomal formulations for drug delivery, in particular, liposomal formulations for ocular drug delivery. More specifically, various embodiments relate to sustained timolol maleate delivery from liposomes for glaucoma therapy and ocular hypertension.
PROCESS FOR FORMULATING AN ANIONIC AGENT
Formulations comprising anionic agents such as nucleic acids within a lipid-containing particle methods of formulating a lipid-containing particle comprising an anionic agent such as a nucleic acid, methods for preparing a lipid-containing particle comprising an anionic agent such as a nucleic acid, methods for therapeutic delivery of an anionic agent to a patient in need thereof, where the anionic agent is formulated in a lipid-containing particle as described herein.
NANOLIPOGEL VEHICLES FOR CONTROLLED DELIVERY OF DIFFERENT PHARMACEUTICAL AGENTS
A “nanolipogel” is a delivery vehicle including one or more lipid layer surrounding a hydrogel core, which may include an absorbent such as a cyclodextrin or ion-exchange resin. Nanolipogels can be constructed so as to incorporate a variety of different chemical entities that can subsequently be released in a controlled fashion. These different incorporated chemical entities can differ dramatically with respect to size and composition. Nanolipogels have been constructed to contain co-encapsulated proteins as well as small hydrophobic drugs within the interior of the lipid bilayer. Agents incorporated within nanolipogels can be released into the milieu in a controlled fashion, for example, nanolipogels provide a means of achieving simultaneous sustained release of agents that differ widely in chemical composition and molecular weight. Additionally, nanolipogels can favorably modulate biodistribution.
High-efficiency encapsulation of hydrophilic compounds in unilamellar liposomes
The present invention relates to high-efficiency encapsulation of hydrophilic substances in the hydrophilic space of unilamellar liposomes. High-efficiency encapsulation is achieved by the use of a polyhydric alcohol selected from propylene glycol or glycerine for dissolving the hydrophobic compounds forming the lipid bilayer of the liposomes. The invention provides unilamellar liposomes (UL) as well as a method for preparing same by way of low temperature extrusion. The invention also relates to use of these UL in the manufacturing of a medicament, a cosmetic product, a food additive or a disinfectant.
IRINOTECAN LIPOSOME PREPARATION, AND PREPARATION AND APPLICATION THEREOF
An irinotecan liposome preparation, a preparation method, and use thereof. The irinotecan liposome includes: irinotecan, a liposome carrier, an internal aqueous phase located inside a liposome membrane and an external aqueous phase located outside the liposome membrane, the irinotecan being encapsulated in the internal aqueous phase; a sulfonate gradient exists between the internal aqueous phases inside the liposome membrane and the external aqueous phase outside the liposome membrane. The liposome takes monovalent sulfonate and disulfonate as the internal aqueous phases, encapsulates the irinotecan in the internal aqueous phases of the liposome in the form of insoluble sulfonate or disulfonate, and has a good sustained-release effect.
POLYNUCLEOTIDE ENCAPSULATION AND PRESERVATION USING SELF-ASSEMBLING MEMBRANES
Polynucleotides such as DNA are stored inside vesicles formed from self-assembling membranes. The vesicles may be protocells, liposomes, micelles, colloidosomes, proteinosomes, or coacervates. The vesicles may include surface functionalization to improve polynucleotide encapsulation and/or to bind polynucleotides having specific sequences. Encapsulation in vesicles provides protection for the polynucleotides. Additional protection is provided by addition of one or more stabilizers. The stabilizer may be nucleic-acid stabilizers that stabilize the polynucleotides or may be a protective structural layer around the vesicles such as a layer of silica. A process for stably storing polynucleotides in vesicles and a process for recovering stored polynucleotides from vesicles are both disclosed. The polynucleotides may be used for storage of digital information.
