Lanosterol, also known as lanosterin, belongs to the class of organic compounds known as triterpenoids. These are terpene molecules containing six isoprene units. Thus, lanosterol is considered to be a sterol lipid molecule. Lanosterol is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Lanosterol is biochemically synthesized starting from acetyl-CoA by the HMG-CoA reductase pathway. The critical step is the enzymatic conversion of the acyclic terpene squalene to the polycylic lanosterol via 2,3-squalene oxide.

15(S)-HPETE

15(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).
