1a,1b-dihomo Prostaglandin E2 (PGE2) is a rare polyunsaturated fatty acid first identified in extracts of sheep vesicular gland microsomes, known to contain COX, incubated with adrenicacid . 1a,1b-dihomo PGE2 has also been identified in conditioned media of RAW 264.7 macrophages stimulated with endotoxin and arachidonic acid . This product is thought to be produced by elongation of AA to adrenicacid, which is then metabolized sequentially by COX and PGE synthase.
1-Stearoyl-2-adrenoyl-sn-glycero-3-PE is a phospholipid that contains stearic acid and adrenicacid at thesn-1 andsn-2 positions, respectively. 1-Stearoyl-2-adrenoyl-sn-glycero-3-PE levels are inversely correlated with subject age in mitochondria isolated from human post-mortem hippocampus.1 1.Hancock, S.E., Friedrich, M.G., Mitchell, T.W., et al.Decreases in phospholipids containing adrenic and arachidonic acids occur in the human hippocampus over the adult lifespanLipids50(9)861-872(2015)
1a,1b-Dihomo Prostaglandin F2α (1a,1b-dihomo PGF2α), a hypothetical product of adrenicacid in the COX pathway, is predominantly synthesized in the renal medulla, reflecting the selective distribution of adrenicacid in this region.
10,11-EDT, a substrate for soluble epoxide hydrolase (sEH), is a metabolic derivative of adrenicacid and acts as an endothelium-derived hyperpolarizing factor with potent vasorelaxant effects [1].
