Undecylenic acid-based nanocarriers for targeted drug delivery
Targeted drug delivery systems comprising a therapeutic agent solubilized with undecylenic acid (UA)-based nanocarrier vesicles that may be polymerized or provided as an mPEG ester are provided to achieve targeted delivery of, for example, ROS-activated cytotoxic agents to cancer cells exhibiting high levels of ROS. Methods utilizing photodynamic and sonodynamic generation of ROS to enhance targeted delivery are also provided.
Compositions and methods for the delivery of therapeutics
The present invention provides compositions and methods for the delivery of antivirals to a cell or subject.
DNA-templated micelle and uses thereof
The present invention discloses a multifunctional DNA-templated micelle system that has a payload carrier of at least a DNA bridge and a functionalized polyethylene glycol (PEG) segment. The micelle can be used to deliver molecules, such as drugs and polynucleotides, to targeted cells for pharmaceutical uses. The PEG segment provides a functional group, such as amine, for ligand conjugation. The DNA-templated micelle of the present invention is highly controllable in size, loading efficiency and tissue targeting, and can carry multiple payloads for targeted combination strategies in cancer therapy, such as gene delivery, gene therapy, and immunotherapy.
POLYMERSOMES, COLLOIDOSOMES, LIPOSOMES, AND OTHER SPECIES ASSOCIATED WITH FLUIDIC DROPLETS
The present invention relates generally to vesicles such as liposomes, colloidosomes, and polymersomes, as well as techniques for making and using such vesicles. In some cases, the vesicles may be at least partially biocompatible and/or biodegradable. The vesicles may be formed, according to one aspect, by forming a multiple emulsion comprising a first droplet surrounded by a second droplet, which in turn is surrounded by a third fluid, where the second droplet comprises lipids and/or polymers, and removing fluid from the second droplet, e.g., through evaporation or diffusion, until a vesicle is formed. In certain aspects, the size of the vesicle may be controlled, e.g., through osmolarity, and in certain embodiments, the vesicle may be ruptured through a change in osmolarity. In some cases, the vesicle may contain other species, such as fluorescent molecules, microparticles, pharmaceutical agents, etc., which may be released upon rupture. Yet other aspects of the invention are generally directed to methods of making such vesicles, kits involving such vesicles, or the like.
Magnetic particle conjugates, micelles, and methods of delivering agents
Embodiments of the present disclosure provide for magnetic particle conjugates, methods of making the magnetic particle conjugates, methods of using magnetic particle conjugates, micelles (also referred to as a “magnetic composite nanocarrier” (MCNC)), methods of making micelles, methods of using micelles, and the like.
NANOPARTICLE PHARMACEUTICAL DELIVERY SYSTEM
A method of preparing a nanoparticle pharmaceutical delivery system. A nanoparticle pharmaceutical delivery system. A method of preparing a targeted nanoparticle pharmaceutical delivery system. A targeted nanoparticle pharmaceutical delivery system.
Compositions of fluorocarbon nanoemulsion, and methods of preparation and use thereof
The invention provides novel compositions of fluorocarbon nanoemulsions comprising one or more of fluorosurfactants and phospholipids, and methods of preparation and use thereof for enhanced oxygen delivery.
Membrane-lytic block copolymers
Membrane-lytic block copolymers, micellar assemblies, pharmaceutical compositions, and related methods are described.
CYCLODEXTRIN-BASED GAMMALINOLENIC ACID FORMULATION FOR TREATMENT OF BRAIN CANCER
The present invention features a cyclodextrin-based gamma linolenic acid formulation for the treatment of brain cancer. More specifically, the invention relates to use of cyclodextrin analogs as carriers for gamma-linolenic acid and their pharmacological use. The present invention features GLA formulated as a cyclodextrin inclusion complex for the treatment of cancers of the brain, in particular glioblastoma multiforme and other gliomas, as well as metastatic cancers to the brain including leptomeningeal cancers. The inclusion complexes described herein take advantage of the ability of hydroxypropyl-beta-cyclodextrin (HPbCD), beta-cyclodextrin sulfobutyl ether (bCDSBE), and 2,6-dimethyl-beta-cyclodextrin (DMbCD) to complex with and subsequently solubilize GLA.
Compositions and methods for organ specific delivery of nucleic acids
The present disclosure provides compositions which shown preferential targeting or delivery of a nucleic acid composition to a particular organ. In some embodiments, the composition comprises a steroid or sterol, an ionizable cationic lipid, a phospholipid, a PEG lipid, and a permanently cationic lipid which may be used to deliver a nucleic acid.
