NON-CLEAVABLE POLYMER CONJUGATED WITH ALPHA V BETA 3 INTEGRIN THYROID ANTAGONISTS
Chemical compositions and methods of synthesis thereof. The compositions disclosed and described herein are directed toward and classified as anti-angiogenic thyrointegrin antagonists, which may be capable of reacting with one or more cell surface receptors of the integrin v3 receptor family. Anti-angiogenic thyrointegrin antagonists or derivatives thereof are conjugated via a non-cleavable linker having an amine, diamine or triazole linkage to polymers of Polyethylene Glycol, cyclodextrin, chitosan, alginic acid or hyaluronic acid, forming a single chemical entity. Utility of the compositions disclosed may treat angiogenesis-mediated disorders such as Cancer (Solid tumors and Liquid tumors), ocular disorders (Diabetic Retinopathy and Age-related Macular Degeneration), inflammatory disorders (arthritis, osteoarthritis), atherosclerosis, lesions, and dermatology (Rosacea, Psoriasis, skin cancer) and diseases mediated or dependent upon the generation of new blood cells via angiogenesis to persist and the treatment thereof or dependent on antagonizing the formation of new blood vessels to slow or eliminate angiogenic pathways.
Biomaterials comprising hyaluronic acid binding peptides and extracellular matrix binding peptides for hyaluronic acid retention and tissue engineering applications
The present invention provides novel biomaterial compositions and methods having a technology to improve retention of hyaluronic acid (HA). The biomaterial compositions utilize small HA binding peptides and extracellular matrix binding (ECM) peptides that are tethered to synthetic biocompatible polymers. When tethered to the polymers, the peptide region allows the polymers to bind to HA and to tissues such as cartilage. The novel biomaterial compositions can be used to coat or chemically modify cartilage or tissues with a biologically compatible polymer having HA binding peptides, which allow HA to bind to the surface of the cartilage or tissues. Methods of using same are also provided.
NON-LINEAR MULTIBLOCK COPOLYMER-DRUG CONJUGATES FOR THE DELIVERY OF ACTIVE AGENTS
Non-linear multiblock copolymer-drug conjugates for the treatment and prevention of diseases and disorders of the eye are provided. The polymer-drug conjugates can form nanoparticles, microparticles, and implants that are capable of effectively delivering therapeutic levels of one or more active agents for an extended period of time. Administration to the eye of an active agent in the form of a non-linear multiblock copolymer-drug conjugate produces decreased side effects when compared to administration of the active agent alone. Also provided are methods of treating intraocular neovascular diseases, such as wet age-related macular degeneration as well as diseases and disorders of the eye associated with inflammation, such as uveitis.
Non-cleavable polymer conjugated with αVβ3 integrin thyroid antagonists
Chemical compositions and methods of synthesis thereof. The compositions disclosed and described herein are directed toward and classified as anti-angiogenic thyrointegrin antagonists, which may be capable of reacting with one or more cell surface receptors of the integrin v3 receptor family. Anti-angiogenic thyrointegrin antagonists or derivatives thereof are conjugated via a non-cleavable linker having an amine, diamine or triazole linkage to polymers of Polyethylene Glycol, cyclodextrin, chitosan, alginic acid or hyaluronic acid, forming a single chemical entity. Utility of the compositions disclosed may treat angiogenesis-mediated disorders such as Cancer (Solid tumors and Liquid tumors), ocular disorders (Diabetic Retinopathy and Age-related Macular Degeneration), inflammatory disorders (arthritis, osteoarthritis), atherosclerosis, lesions, and dermatology (Rosacea, Psoriasis, skin cancer) and diseases mediated or dependent upon the generation of new blood cells via angiogenesis to persist and the treatment thereof or dependent on antagonizing the formation of new blood vessels to slow or eliminate angiogenic pathways.
Local delivery of drugs from self assembled coatings
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.
Antimicrobial constructs
The invention is based on the recognition that known antimicrobial compounds, such as nisin or other lantibiotics, can be made to form a long lasting antimicrobial surface coating by linking the peptide with a block polymer, such as PLURONIC F108 or an end group activated polymer (EGAP) in a manner to form a flexible tether and/or entrap the peptide. The entrapped peptide provides antimicrobial action by early release from entrapment while the tethered peptide provides longer lasting antimicrobial protection. Antimicrobial gels and foams may be prepared using the antimicrobial peptide containing block copolymers.
Non-linear multiblock copolymer-drug conjugates for the delivery of active agents
Non-linear multiblock copolymer-drug conjugates for the treatment and prevention of diseases and disorders of the eye are provided. The polymer-drug conjugates can form nanoparticles, microparticles, and implants that are capable of effectively delivering therapeutic levels of one or more active agents for an extended period of time. Administration to the eye of an active agent in the form of a non-linear multiblock copolymer-drug conjugate produces decreased side effects when compared to administration of the active agent alone. Also provided are methods of treating intraocular neovascular diseases, such as wet age-related macular degeneration as well as diseases and disorders of the eye associated with inflammation, such as uveitis.
DRUG DELIVERY SHOCK WAVE BALLOON CATHETER SYSTEM
A catheter comprises an elongated carrier and a balloon carried by the carrier in sealed relation thereto. The balloon has an outer surface and is arranged to receive a fluid therein that inflates the balloon. The catheter further comprises a shock wave generator within the balloon that forms mechanical shock waves within the balloon, and a medicinal agent carried on the outer surface of the balloon. The medicinal agent is releasable from the balloon either before or in response to the shock wave.
MATERIALS FOR PHOTOTHERAPIES OF OPHTHALMIC DISEASES
The present invention relates to a medicinal material for light therapy, comprising a matrix material and a photosensitizer, wherein the photosensitizer is dispersed inside the matrix material by copolymerization, is mixed inside the matrix material, or attached to the surface of the matrix material by surface grafting, modification, coating and the like. The present material can kill diseased tissue cells with a radiation under selected wavelength so as to obtain a phototherapy treatment of ophthalmic diseases. The present invention also provides a process for preparing the material and a use in preparing an ophthalmic medical device.
THROMBIN-RESPONSIVE HYDROGELS AND DEVICES FOR AUTO-ANTICOAGULANT REGULATION
The present disclosure relates to a thrombin-responsive closed-loop patch for prolonged heparin delivery in a feedback-controlled manner. The microneedle-based patch can sense the activated thrombin and subsequently release heparin to prevent coagulation in the blood flow. The patch can be transcutaneously inserted into skin without drug leaking and can sustainably regulate blood coagulation in response to thrombin.
