Summary for Patent: 5,977,174
Title: | Cholinergic compositions and uses thereof |
Abstract: | The invention provides compositions that include conjugates of a cholinergic agent and a fatty acid, preferably cis-docosahexaenoic acid. The conjugates are useful in treating disorders resulting from cerebral ischemia including stroke. |
Inventor(s): | Bradley; Matthews O. (Laytonsville, MD), Shashoua; Victor E. (Belmont, MA), Swindell; Charles S. (Merion, PA), Webb; Nigel L. (Bryn Mawr, PA) |
Assignee: | Neuromedica, Inc. (Conshohocken, PA) |
Application Number: | 08/978,540 |
Patent Claims: | 1. A method for treating stroke comprising
administering to a subject in need of such treatment an amount of a covalent conjugate of a cholinergic agent and a fatty acid having 12-26 carbons in an amount effective to treat stroke. 2. The method of claim 1, wherein the fatty acid is docosahexaenoic acid. 3. The method of claim 1 with the proviso that the cholinergic agent is not acetylcholine chloride, arecoline HBr, bethanechol chloride, carbachol, cis-dioxolane,(+)-, (4-hydroxy-2-butynyl)-1-trimethylammonium m-chlorocarbonilate chloride, methacholine chloride, metoclopramide HCl, muscarine chloride,(+)-, muscarine chloride(+)-, nicotine tartrate,S(-)-, cis-2-methyl-5-trimethylammoniummethyl-1,3-oxathiolane iodide (OXA-22), oxotremorine, oxotremorine sesquifumarate or pilocarpine HCl,(+)-. 4. The method of claim 3, further comprising administering to the subject an anti-stroke agent. other than the covalent conjugate and wherein the anti-stroke agent is selected from the group consisting of antiplatelet agents, anticoagulation agents, cholinergic agents, thrombolytic agents including plasminogen activators, antithrombotics, neuroprotective agents, platelet activating factor antagonists, platelet aggregation inhibitors, post-stroke and post-head trauma treatments, cerebral ischemia agents, basic fibroblast growth factors and steroids. 5. The method of claim 3 wherein the anti-stroke agent is selected from the group consisting of citicholine, dizocilpine, alteplase, urokinase, and lexipafant. 6. A method for protecting cortical cells from ischemia-induced cell death comprising contacting the cortical cells which have been exposed to ischemic conditions sufficient to induce cell death with a covalent conjugate of a cholinergic agent and a fatty acid having 12-26 carbons in an amount effective to protect the cortical cells against cell death which would otherwise result from the ischemic conditions. 7. The method of claim 6, wherein the fatty acid is docosahexaenoic acid. 8. A method for selectively protecting cortical cells of a subject from stroke-induced cell death comprising administering to a subject in need of such treatment a covalent conjugate of a cholinergic agent and a fatty acid having 12-26 carbons in an amount effective to protect the cortical cells from stroke induced cell death. 9. The method of claim 8, wherein the fatty acid is docosahexaenoic acid. 10. The method of claim 1, wherein the fatty acid is an unbranched, naturally-occurring fatty acid. 11. The method of claim 10, wherein the fatty acid has 14-22 carbons. 12. The method of claim 1, wherein the fatty acid is conjugated to the cholinergic agent via an ester bond involving the COOH of the fatty acid. 13. The method of claim 6, wherein the fatty acid is an unbranched, naturally-occurring fatty acid. 14. The method of claim 13, wherein the fatty acid has 14-22 carbons. 15. The method of claim 6, wherein the fatty acid is conjugated to the cholinergic agent via an ester bond involving the COOH of the fatty acid. 16. The method of claim 8, wherein the fatty acid is an unbranched, naturally-occurring fatty acid. 17. The method of claim 9, wherein the fatty acid has 14-22 carbons. 18. The method of claim 8, wherein the fatty acid is conjugated to the cholinergic agent via an ester bond involving the COOH of the fatty acid. a second container containing an anti-stroke agent other that the covalent conjugate. |
