Deuterated arachidonic acid-d5
WebLipoxygenases (LOs) catalyze lipid peroxidation and have been implicated in a number of human diseases connected to oxidative stress and inflammation. These enzymes have also attracted considerable attention due to large kinetic isotope effects (30−80) for the rate-limiting hydrogen abstraction step with linoleic acid (LA) as substrate. Herein, we report … WebJun 15, 1987 · Even though 100 microM deuterated arachidonic acid results in 20-30 microM deuterated 5-HPETE, 80 microM exogenous 5-HPETE in the incubation could reduce the amount of deuterated LTA4 by only approx. 20%. The present study would thus indicate that the arachidonic acid moiety is preferentially converted to LTA4 in a …

WebDeuterated metabolites resulting from retroconversion to 18:3-d6 and subsequent metabolism by classical pathways represented 35.3% of the total deuterated fatty acids. The retroconversion product (18:4n-3-d6) of 20:4n-3-d6 and/or -d8 was 9.0% of the total. Webmembrane levels of drug were 21% and 19% of total linoleic acid. Importantly, levels of di-deuterated arachidonic acid (D2 -AA) in both plasma and RBC also increased, indicating normal enzymatic processing of the stabilized LA into stabilized AA. The researchers concluded that incubation of MSCs derived from PSP patients with R T001 reduces
