• 개요

  Leukotriene B₄ (LTB₄) is a dihydroxy fatty acid derived from arachidonic acid through the 5-LO pathway. It promotes a number of leukocyte functions including aggregation, stimulation of ion fluxes, enhancement of lysosomal enzyme release, superoxide anion production, chemotaxis, and chemokinesis. 12-oxo LTB₄ is an initial metabolite of LTB₄ formed via the LTB₄ 12-hydroxydehydrogenase pathway. It is rapidly converted to 10,11-dihydro-12-oxo-LTB₄, followed by reduction of the 12-oxo group to give 10,11-dihydro-LTB₄. 12-oxo-LTB₄ (EC₅₀ = 33 nM) is about 70-fold less potent than LTB₄ (EC₅₀ = 0.46 nM) at stimulating Ca²⁺ mobilization in human neutrophils. It is also significantly less potent than LTB₄ at stimulating neutrophil migration with EC₅₀ values of 170 and 2.7 nM for 12-oxo-LTB₄ and LTB₄, respectively.
