摘要:
This invention relates to compositions and methods for treatment of vascular conditions. The invention provides arginine polymers and arginine homopolymers for the treatment and/or prevention of glaucoma, pulmonary hypertension, asthma, chronic obstructive pulmonary disease, erectile dysfunction, Raynaud's syndrome, heparin overdose, vulvodynia, and wound healing. The invention also provides arginine polymers and arginine homopolymers for use in organ perfusate and preservation solutions.
摘要:
This invention provides compositions and methods for enhancing delivery of drugs and other agents across epithelial tissues, including the skin, gastrointestinal tract, pulmonary epithelium, and the like. The compositions and methods are also useful for delivery across endothelial tissues, including the blood brain barrier. The compositions and methods employ a delivery enhancing transporter that has sufficient guanidino or amidino sidechain moieties to enhance delivery of a compound conjugated to the reagent across one or more layers of the tissue, compared to the non-conjugated compound. The delivery-enhancing polymers include, for example, poly-arginine molecules that are preferably between about 6 and 25 residues in length.
摘要:
Methods and compositions for transporting drugs and macromolecules across biological membranes are disclosed. In one embodiment, the invention includes a method for enhancing transport of a selected compound across a biological membrane, wherein a biological membrane is contacted with a conjugate containing a biologically active agent that is covalently attached to a transport polymer. In one embodiment, the polymer consists of from 6 to 25 subunits, at least 50% of which contain a guanidino or amidino sidechain moiety. The polymer is effective to impart to the attached agent a rate of trans-membrane transport across a biological membrane that is greater than the rate of trans-membrane transport of the agent in non-conjugated form.

摘要:
Cardiovascular cell proliferation in a blood vessel subjected to trauma, such as angioplasty, vascular graft, anastomosis, or organ transplant, can be inhibited by contacting the vessel with a polymer consisting of from 6 to about 30 amino acid subunits, where at least 50% of the subunits are arginine, and the polymer contains at least six contiguous arginine subunits. Exemplary polymers for this purpose include arginine homopolymers 7 to 15 subunits in length.

摘要:
This invention provides compositions and methods for enhancing delivery of drugs and other agents across epithelial tissues, including the skin, gastrointestinal tract, pulmonary epithelium, ocular tissues and the like. The compositions and methods are also useful for delivery across endothelial tissues, including the blood brain barrier. The compositions and methods employ a delivery enhancing transporter that has sufficient guanidino or amidino sidechain moieties to enhance delivery of a compound conjugated to the reagent across one or more layers of the tissue, compared to the non-conjugated compound. The delivery-enhancing polymers include, for example, poly-arginine molecules that are preferably between about 6 and 25 residues in length.
摘要:
The present invention provides compositions and methods for enhancing transport of biologically active compounds across biological membranes and across and into animal epithelial or endothelial tissues. The composition includes a biologically active agent and a transport moiety. The transport moiety includes a structure selected from the group consisting of (ZYZ)nZ, (ZY)nZ, (ZYY)nZ and (ZYYY)nZ. Subunit “Z” is L-arginine or D-arginine, and subunit “Y” is an amino acid that does not comprise an amidino or guanidino moiety. Subscript “n” is an integer ranging from 2 to 10. The method for enhancing transport involves the administration of the aforementioned composition.
