Levuglandin D2
Levuglandin D2 is one of the products of a non-enzymatically rearrangement of prostaglandin H2 (PGH2) to this highly reactive gamma-keto aldehyde. PGH2 markedly accelerates the formation of dimers and higher oligomers of amyloid beta1-42. This evidence implicates cyclooxygenase activity in the pathogenesis of Alzheimers disease, and is associated with the formation of levuglandin adducts of the peptide. Levuglandins (LGs) and their stereo and structural isomers are extraordinarily reactive γ-ketoaldehydes that are generated by rearrangements of prostanoid endoperoxide intermediates of polyene cyclooxygenation. Their rapid adduction with biological nucleophiles results, inter alia, in pathological modifications of proteins and DNA. It also complicates their detection. Cyclooxygenase-promoted lipid oxidation is a pivotal step in the biosynthesis of an array of physiologically active metabolites. COX fosters a highly regio and stereoselective cyclooxygenation of arachidonic acid (AA) to deliver a single, enantiomerically pure endoperoxide, PGH2, that is a branch point in the biosynthesis of numerous hormone-like mediators of cellular activities. Spontaneous rearrangements of PGH2 were known to generate prostaglandins (PG) PGD2 and PGE2.
