摘要:
The present invention relates to novel conjugates of active principles grafted to a polymer, to the nanoparticles comprising them, to their preparation and to their polymeric intermediates.
摘要:
A delivery system using materials that form a liquogel or nanocarrier are described. The delivery system comprises hyperbranched polyglycerols (HPGs). The delivery system can include a drug or therapeutic agent and this system can be used to administer the drug or therapeutic agent locally. The delivery system provides for controlled release of the drug or therapeutic agent.
摘要:
Peptides that selectively bind to antigens exposed in vascular disease or dysfunction have been identified by biopanning a phage library. The ligands are useful when attached to a substrate to be in contact with endothelial surfaces, especially those where drug delivery is utilized, such as following angioplasty, with release from a drug delivery reservoir in a medical device such as a stent, or by administration intravenously in the form of nano or microparticles, although the peptides may also be used with other medical devices or substrates, for targeting or to increase adhesion to endothelial surfaces. The nanoparticle technology can be used to treat injured vasculature, a clinical problem of primary importance. The targeted nanoparticles are also useful in the treatment of other diseases and disorders such as oncologic and regenerative diseases and indications where neoangiogenesis is commonly observed.
摘要:
The invention relates to oligofluorinated coatings and their use in drag delivery The oligofluorinated coatings are compositions comprising formula (XVII). These coatings are used in a method of delivering a biologically active agent to a tissue surface in a mammalian tissue This method occurs by contacting the surface with the coating including an oligofluorinated oligomer and a biologically active agent wherein the coating resides on the tissue surface and release the biologically active agent to the tissue surface.
摘要:
This invention relates to compositions, and related methods, of synthetic nanocarriers that comprise immunomodulatory agents and antigens that are differentially released from the synthetic nanocarriers.
摘要:
Polyal-Drug conjugates comprising a variable rate-releasing linker are described along with methods of making such conjugates. Uses for such Polyal-Drug conjugates is also described.
