Common Name15(S)-HPETE
Description15(S)-hydroperoxyeicosatetraenoic acid (15(S)-HPETE) is the corresponding hydroperoxide of 15(S)-HETE and undergoes homolytic decomposition to the DNA-reactive bifunctional electrophile 4-oxo-2(E)-nonenal, a precursor of heptanone-etheno-2'-deoxyguanosine. Reactive oxygen species convert the omega-6 polyunsaturated fatty acid arachidonic acid into (15-HPETE); vitamin C mediates 15(S)-HPETE decomposition. 15(S)-HPETE initiates apoptosis in vascular smooth muscle cells. 15(S)-HPETE is a lipoxygenase metabolite that affects the expression of cell adhesion molecules (CAMs) involved in the adhesion of leukocytes and/or the accumulation of leukocytes in the vascular endothelium, these being the initial events in endothelial cell injury. 15(S)-HPETE induces a loss of cardiomyocytes membrane integrity. 15-(S)HPETE is a hydroperoxide that enhances the activity of the enzymes lipoxygenase [EC 1.13.11.12] And Na+, K+-ATPase [EC 3.6.3.9] Of brain microvessels. Lipoxygenase(s) and Na+-K+-ATPase of brain microvessels may play a significant role in the occurrence of ischemic brain edema. (PMID: 15964853 , 15723435 , 8655602 , 8595608 , 2662983 ) [HMDB]
