摘要:
The present invention is directed to peptisomes, including nanopeptisomes, which have a perfluorocarbon liquid core containing a perfluorocarbon liquid and a cargo, such as a therapeutically active agent, dispersed in the perfluorocarbon. liquid, and a plurality of amphiphilic peptide molecules surrounding the perfluorocarbon liquid core, wherein the amphiphilic peptide is represented by Formula (I) HB-CL-HP wherein HB is a fluorinated hydrophobic block, such as a fluorinated hydrophobic amino acid sequence, CL is a cross-linking motif, and HP is a hydrophilic amino acid sequence. The present invention is also directed to methods of use of the amphiphilic peptides and peptisomes, such as nanopeptisomes, to deliver a cargo, such as a therapeutically active agent, to a cell, wherein the cell may be in vitro , ex vivo , or in vivo .
摘要:
The present invention relates to polymersomes that contain an encapsulated drug and that exhibit chemotaxis in response to a chemical stimulus. The chemotactic polymersomes can be targeted in vivo to a location of therapeutic interest with high specificity and selectivity. The present invention also provides related pharmaceutical compositions and therapeutic methods.
摘要:
The described invention provides a topical delivery system comprising a pharmaceutical composition for application directly to a skin of a subject in need thereof comprising (a) an effective therapeutic amount of an active therapeutic agent; (b) chemical drivers comprising an amino benzoate local anesthetic, ethoxydiglycol and methylsulfonylmethane (MSM) that in combination are effective to synergistically deliver the therapeutic agent; and (c) a depot component for keeping the pharmaceutical composition in the skin. Methods for delivering an active therapeutic agent into skin, for keeping it in the skin, for reducing systemic side effects attributable to entry of the active agent into the blood stream, and a method for treating a condition, disease or disorder of skin topically also are described in accordance with the embodiments of the described invention.
摘要:
The present invention is directed to a liposome composition for use in the peritoneal dialysis of patients suffering from endogenous or exogenous toxicopathies, wherein the pH within the liposomes differs from the pH in the intraperitoneal cavity and wherein the pH within the liposome results in a liposome-encapsulated charged toxin. The inventtion also relates to a pharmaceutical composition comprising said liposomes. A further aspect of the present invention relates to a method of treating patients suffering from endogenous or exogenous toxicopathies, preferably selected from drug, metabolite, pesticide, insecticide, toxin, and chemical warfare toxicopathies, more preferably hyperammonemia, comprising the step of administering liposomes of the invention in a therapeutically effective amount into the peritoneal space of a patient in need thereof. Next to human, the present invention is particularly suitable to veterinary aspects.
摘要:
Methods and compositions for improving the delivery and/or efficacy of cancer therapeutics are disclosed. Methods and compositions for treating or preventing a cancer (e.g., a solid tumor such as a desmoplastic tumor) by administering to a subject an antihypertensive agent, as a single agent or combination with a cancer therapeutic agent (for example, a therapeutic agent ranging in size from a large nanotherapeutic to a low molecular weight chemotherapeutics and/or oxygen radical) are disclosed.
摘要:
Compositions and methods for treating or ameliorating the symptoms of inflammatory or autoimmune disease or disorder are described herein. The compositions contain a nanolipogel for sustained delivery of an effective amount of one or more active agents of choice, preferably a drug for treating or ameliorating the symptoms of inflammatory or autoimmune disease or disorder. The nanolipogel includes a lipid bilayer surrounding a hydrogel core, which may optionally include a host molecule, for example, an absorbent such as a cyclodextrin or ion-exchange resin. In preferred embodiments at least one of active agents is an immunosuppressant.

The invention relates to soluble selenium compositions and methods of production, separation and purification thereof. In particular the present invention provides methods of preparing water soluble selenoglycoproteins (e.g., via extracting selenoglycoproteins from selenium enriched yeast), methods of supplementing a selenium deficient composition via admixing water soluble selenoglycoproteins with the selenium deficient composition, compositions comprising the water soluble selenoglycoproteins and methods of administering the same.
摘要:
Delivery systems based on liposomes functionalized with peptides and chelating agents, for therapy and imaging by selective targeting of tumour cells expressing the receptors GRP, BBl, BB2, BB3 e BB4 and any other receptor which recognizes the bombesin peptide or analogues thereof are described. In particular, the liposomes contain within them cytotoxic drugs, such as for example doxorubicin, for target-selective antitumour therapy, and, through the presence of the chelating agent, can contain radioactive or paramagnetic ions for the real time visualization of the tumour cells. The liposomes described in this invention thus act as a selective delivery system for drugs and/or contrast agents onto tumour cells expressing the receptors for the class of known peptides such as bombesin (endogenous sequence, analogous or peptidomimetic peptides, agonists or non agonists).
摘要:
Techniques, systems, devices and materials are disclosed for implementing and fabricating drug delivery and imaging vehicles, which are activated in the body at a tissue of interest by focused ultrasound. In one aspect, a drug delivery vehicle can include a carrier having an outer membrane that envelopes an acoustic sensitizer particle and a payload substance to be delivered to the target tissue. The outer membrane can protect the acoustic sensitizer particle and the payload substance from degradation and opsonization. The outer membrane can be functionalized with a tumor targeting ligand to cause the drug delivery vehicle to selectively accumulate in a tumor region over other tissues, as well as with an agent to increase circulation time by reducing uptake from undesired body tissues, organs, and systems.
