Abstract: Disclosed are methods for inhibiting the progression of neurodegenerative disease. The methods include administering to a patient suffering from such a disease a composition comprising deuterated arachidonic acid or an ester thereof.

Abstract: Disclosed are diagnostic methods for assessing the presence or absence of a therapeutic concentration of a deuterated polyunsaturated fatty acid in diseased neurons during treatment of a patient with a neurodegenerative disease.

Abstract: Disclosed are methods or dosing protocols for administering deuterated arachidonic acid or a prodrug thereof to a patient in order to accelerate the time required to achieve of a therapeutic concentration of 13,13-D2-arachidonic acid in vivo.

Abstract: Methods for preparing isotopically modified 1,4-diene systems from non-isotopically modified 1,4-dienes involve selective oxidation of one or more bis-allylic position(s), or the preparation of isotopically modified 1,4-diene systems via trapping pi-allylic complexes with a source of deuterium or tritium. Such methods are useful for preparing isotopically modified polyunsaturated lipid including polyunsaturated fatty acids and polyunsaturated fatty acid derivatives.

Abstract: Disclosed are methods for inhibiting the progression of neurodegenerative disease. The methods include administering to a patient suffering from such a disease a composition comprising either deuterated linoleic acid or an ester thereof.

Abstract: Disclosed are methods for inhibiting cellular dysfunctionality and subsequent cell death due to cellular accumulation of oxidized polyunsaturated fatty acids (PUFAs) products wherein said accumulation is mediated, at least in part, by impaired enzymatic process(es) that are responsible for neutralizing said oxidized products.

Abstract: Disclosed are methods for inhibiting the progression of Amyotrophic Lateral Sclerosis (ALS). The methods include administering to a patient suffering from ALS a composition comprising either deuterated linoleic acid or an ester or deuterated arachidonic acid or an ester thereof.

Abstract: Methods are provided of identifying a subject having impaired aldehyde dehydrogenase activity; and administering to the subject a compound comprising an isotopicaliy-modified polyunsaturated fatty acid, an isotopicaliy-modified polyunsaturated fatty acid ester, an isotopicaliy-modified polyunsaturated fatty acid thioester, an isotopicaliy-modified polyunsaturated fatty acid amide, a polyunsaturated fatty acid mimetic, or an isotopicaliy-modified polyunsaturated fatty acid pro-drug, the compound having an isotopic modification that reduces oxidation of the compound, thereby reducing production in the subject of substrate for aldehyde dehydrogenase. Some aspects provide coadministering an isotopicaliy-modified polyunsaturated fatty acid and an oxylipin.

Abstract: Deuterated polyunsaturated fatty acid (“PUFA”) compounds, compositions, and uses of the compounds for reducing lipid autooxidation and the treatment of various diseases and conditions are provided.
