12-epi leukotriene b-4

Leukotriene B4 (LTB4) compounds are produced by both enzymatic and non-enzymatic processes. The products of enzymatic origin, via Leukotriene A4 (LTA4) hydrolase, are stereospecifically 12(R). Non-enzymatic hydrolysis products are 50:50 mixtures at C-12, but are almost exclusively trans at C-6. Thus, the non-enzymatic hydrolysis product of LTA4 is 6-trans-12-epi LTB4. 12-epi LTB4 is an isomer which would not be expected to occur in either non-enzymatic hydrolysis products, or in the enzymatic products of LTA4 hydrolase. Compared to LTB4, 12-epi LTB4 has significantly reduced activity for the LTB4 receptor on human neutrophils (IC50 of 7.5 mM), and on guinea pig lung membranes with a (Ki of 4.7 mM). 12-epi LTB4 is an weak agonist at both the recombinant human BLT1 and BLT2 receptors, requiring approximately 10 mM for full activation of the receptor.

Cyclotraxin B acetate is an antagonist of TrkB receptors; inhibits BDNF-induced TrkB activity (IC50 = 0.30 nM). Allosterically alters TrkB receptor conformation but does not alter BDNF binding. Prevents BDNF-induced cold allodynia in mice. Also shown to exhibit putative anxiolytic properties in mice.

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.
