Nitrated-fatty acids modulation of type II diabetes
View Patent ↗Nitro oleic acid and related metabolites are agonists of PPAR-γ. Surprisingly, nitro oleic acid is a more potent agonist of PPAR-γ, relative to nitro linoleic acid. Thus, nitro oleic acid and its metabolites, as well as their pharmaceutically acceptable salts and prodrug forms, are candidate therapeutics for the treatment of type-2 diabetes, which results from insulin resistance accompanying the improper functioning of PPAR-γ.
1. A pharmaceutical composition, comprising (A) an active agent selected from nitro oleic acid and a metabolite of nitro oleic acid, or a pharmaceutically acceptable salt or prodrug of said active agent, and (B) a pharmaceutically acceptable carrier.
2. The pharmaceutical composition of claim 1 , wherein the active agent is nitro oleic acid.
3. The pharmaceutical composition of claim 1 , wherein the pharmaceutical composition is formulated as a solution, suspension, solid, or emulsion.
4. The pharmaceutical composition of claim 1 , wherein the pharmaceutical composition further comprises one or more thickeners, diluents, solvents, buffers, preservatives, surface active agents, excipients, and combinations thereof.
5. The pharmaceutical composition of claim 1 , wherein the pharmaceutical composition further comprises one or more therapeutic agents in addition to the nitro oleic acid.
6. The pharmaceutical composition of claim 1 , wherein the one or more therapeutic agents are selected from the group consisting of cytokines, chemokines, and regulators of growth factors.
7. The pharmaceutical composition of claim 1 , wherein the nitro oleic acid comprises a single regioisomer of nitro oleic acid or both regioisomers of nitro oleic acid.
8. The pharmaceutical composition of claim 1 , further comprising combining a solid form of the nitro oleic acid with a liquid to form a solution or suspension before administering.
9. The pharmaceutical composition of claim 1 , wherein the pharmaceutical composition further comprises an ingredient for preventing microbial infection, an ingredient for preventing inflammation, an anesthetic, or combinations thereof.
10. The pharmaceutical composition of claim 1 , wherein the pharmaceutically acceptable salt comprises a salt formed by the reaction of nitro oleic acid with an inorganic base selected from the group consisting of sodium hydroxide, ammonium hydroxide, potassium hydroxide, monoalkyl amine, dialkyl amine, trialkyl amine, aryl amine, substituted ethanolamine, and combinations thereof.
11. The pharmaceutical composition of claim 1 , the prodrug comprises a methyl or ethyl ester of nitro oleic acid.
12. The pharmaceutical composition of claim 1 , wherein the pharmaceutical composition further comprises one or more agents to maintain osmolarity selected from the group consisting of sodium chloride, Ringer's dextrose, dextrose, lactated Ringer's solution, fluid and nutrient replenishers, and combinations thereof.
13. A method for treating inflammation, comprising the step of administering to a subject in need thereof a pharmaceutical composition comprising an active agent selected from nitro oleic acid and a metabolite of nitro oleic acid, or a pharmaceutically acceptable salt or prodrug thereof and a pharmaceutically acceptable excipient, carrier, or combination thereof.
14. A method for regulating blood glucose levels in a subject in need thereof, comprising the step of administering to the subject a pharmaceutical composition comprising an active agent selected from nitro oleic acid and a metabolite of nitro oleic acid, or a pharmaceutically acceptable salt or prodrug thereof and a pharmaceutically acceptable excipient, carrier, or combination thereof.
15. A method for gauging efficacy of a treatment for type-2 diabetes, comprising the steps of: (A) administering treatment to a subject with at least an active agent selected from nitro oleic acid and a metabolite of nitro oleic acid, or a pharmaceutically acceptable salt or prodrug of such active agent; (B) obtaining a first and a second sample from a subject suffering from type-2 diabetes, wherein the samples are obtained at different times during said treatment; (C) determining blood glucose levels in said first and second samples; and (D) comparing the blood glucose level between said samples, whereby a lower blood glucose level in said second sample is an indicator of efficacy of said treatment.
