An aspirin-triggered lipoxin that inhibits LTB4-induced chemotaxis, adherence, and transmigration of the neutrophils with twice the potency of LXA4 demonstrating activity in the nM range.

11-KT is a second key androgenic steroid found in fish. It occurs in males together with testosterone in amounts which vary from less than 1 ng/ml to as much as 50-100 ng/ml, depending on the species and the stage of the reproductive cycle.

A potential cytochrome P450 metabolite of N-arachidonoyl taurine that may activate TRPV1 and TRPV4.

11β-PGF2α-EA is the theoretical hepatic metabolite of PGD2-EA, produced during COX-2 metabolism of the endogenous cannabinoid AEA which is found in brain, liver, and other mammalian tissues. AEA can be used directly by COX-2 and specific PG synthase to produce ethanolamide congeners of…

11β-PGF2α is the primary plasma metabolite of PGD2 in vivo, the levels of which can increase from 6 pg/ml in a normal healthy volunteer to 490 ng/ml in patients with systemic mastocytosis. The normal human urinary excretion of 11β-PGF2α is about 11 ng/mmol creatinine (~400…

Complex II (succinate dehydrogenase/co-enzyme Q reductase) is one of the major sites of electron entry into the mitochondrial electron transport chain (ETC). Complex II catalyzes the oxidation of succinate to fumarate, and in the process reduces ubiquinone (Q) to ubiquinol (QH2). Ultimately,…

A major CYP450 metabolite of arachidonic acid that is released from the kidney in response to angiotensin II; a potent vasodilator of renal preglomerular vessels; blocks 20-HETE-induced vasoconstriction of renal arterioles at 1 µM.

Cayman’s PC Assay provides a specific, sensitive, and convenient method for quantifying PC in plasma or serum. In this assay, PC-Specific PLD hydrolyzes PC to choline and phosphatidic acid. The newly formed choline is then used to generate hydrogen peroxide in a reaction catalyzed by choline…

ALA is an essential fatty acid found in leafy green vegetables. ALA, as part of a low saturated fat diet, helps prevent cardiovascular disease. ALA decreases blood pressure, serum cholesterol levels, and platelet aggregation.

An isomer of Vitamin E that has less potent antioxidant properties than α-tocotrienol.

An epoxygenase pathway product produced from EPA by CYP450 both in vitro and in vivo; its effects of remain to be determined.

An internal standard for the quantification of trans-resveratrol by GC- or LC-MS.
