Application

LY255283, a competitive leukotriene B4 receptor antagonist, is used in leukotriene receptor research along with other selective leukotriene receptor agonists and antagonist to identify and differentiate the physiological and cell signaling effects of the leukotriene B4 receptor on processes such as paclitaxel resistance in MCF-7/DOX breast cancer cells, monocyte-derived dendritic cell chemotaxis, and 5-lipoxygenase activity and interleukin-8 production in human neutrophils. LY255283 may be used to help verify that an observed process or cell event is leukotriene B4 receptor-dependent.

Biochem/physiol Actions

LY255283 is a competitive leukotriene B4 receptor antagonist, with an IC50 of about 100 nM. It is somewhat selective for the BLT2 receptor, since IC50 values at the BLT1 receptor are >10 μM. LY255283 reduces airway obstruction in animal models of asthma.

The majority of prostate cancer-related deaths are associated with advanced and metastatic malignancies. Although anoikis resistance has been recognized as one of the hallmarks of metastatic prostate malignancies, the molecular events that cause anoikis resistance are poorly understood. In this

Addition of submicromolar concentrations of arachidonic acid (AA) to human neutrophils induced a 2-fold increase in the activity of a cytosolic phospholipase A2 (PLA2) when measured using sonicated vesicles of 1-stearoyl-2-[14C]arachidonoylphosphatidylcholine as substrate. A similar increase in cytosolic PLA2 activity

Leukotriene B4 (LTB4), a potent chemotactic and immune-modulating lipid mediator, signals via two receptors, BLT1 and BLT2, leading to pro-inflammatory responses in phagocytes. Recently, we reported that BLT1 is the predominating BLT on human umbilical vein endothelial cells (HUVEC) and

Polymorphonuclear neutrophils (PMNs) have been implicated in the pathogenesis of the adult respiratory distress syndrome (ARDS). Because leukotriene B4 (LTB4) is a potent activator of PMNs, we sought to determine whether LY255283, an LTB4 receptor antagonist, could block PMN activation
