Combination therapy with nitrated lipids and inhibitors of the renin-angiotensin-aldosterone system
View Patent ↗The present technology provides compositions and methods for treating chronic kidney disease, end-stage renal disease, or diabetic nephropathy. The compositions comprise a nitrated lipid and an inhibitor of the renin-angiotensin-aldosterone system. The methods comprise administering a nitrated lipid in combination with an inhibitor of the renin-angiotensin-aldosterone system to a subject in need thereof, in an amount effective to treat diabetic nephropathy, chronic kidney disease, and/or end-stage renal disease. The use of a nitrated lipid with an inhibitor of the renin-angiotensin-aldosterone system exhibits a synergistic effect in treating chronic kidney disease and diabetic nephropathy.
1. A method of treating hypertensive nephropathy in a subject in need thereof, the method comprising administering to the subject a pharmaceutical composition comprising a nitrated lipid, an inhibitor of the renin-angiotensin-aldosterone system, and a pharmaceutically acceptable carrier, excipient, adjuvant, or a combination thereof.
2. The method of claim 1 , wherein the inhibitor of the renin-angiotensin-aldosterone system is selected from the group consisting of an angiotensin converting enzyme inhibitor, a renin inhibitor, an angiotensin receptor antagonist, and a combination thereof.
3. The method of claim 1 , wherein the nitrated lipid comprises a monounsaturated fatty acid, polyunsaturated fatty acid, or a combination thereof.
4. The method of claim 1 , wherein the nitrated lipid comprises a nitro-oleic acid, a nitro-linoleic acid, or a combination thereof.
5. The method of claim 1 , wherein the nitrated lipid is selected from the group consisting of 9-nitrooleic acid, 10-nitrooleic acid, and a combination thereof.
6. The method of claim 2 , wherein the angiotensin converting enzyme inhibitor is selected from the group consisting of enalapril, ramipril, quinapril, perindopril, lisinopril, benazepril, imidapril, zofenopril, fosinopril, and captopril.
7. The method of claim 2 , wherein the renin inhibitor is selected from the group consisting of aliskiren, remikiren, or renin siRNA.
8. The method of claim 2 , wherein the angiotensin receptor antagonist is selected from the group consisting of losartan, valsartan, telmisartan, irbesartan, azilsartan, olmesartan, candesartan, or eprosartan.
9. The method of claim 2 , wherein the nitrated lipid is nitro-oleic acid and the inhibitor of the renin-angiotensin aldosterone system is an angiotensin converting enzyme inhibitor.
10. The method of claim 1 , wherein the nitrated lipid is 10-nitrooleic acid and the inhibitor of the renin-angiotensin-aldosterone system is losartan.
