Notes: Antagonists of the chemotactic and inflammatory lipoxygenase product leukotriene B4 (LTB4) have been potential drug development targets for several years.{4552,4553} The tetrazole LY255283 is a competitive antagonist of the BLT2 receptor. It displaces radiolabeled LTB4 from guinea pig lung membrane, with an IC50 of about 100 nM.{2084} LY255283 exhibits IC50 values of ~950 nM and >10 µM at human recombinant BLT2 and BLT1 receptors, respectively.{9270} LY255283 inhibits eosinophil chemotaxis by 80% at a concentration of 10 µM, and inhibits the binding of radiolabeled LTB4 to eosinophil membranes with an IC50 of 260 nM.{4552}
