SC-57461A is a selective inhibitor of human recombinant LTB4 with IC50 value of 49 nM [1].LTB4 (leukotriene B (4)) is a leukotriene and plays an important role in inflammation. LTB4 functions through interacting with the specific cell-surface receptors BLTR1 and BLTR2 [2].SC-57461A is a potent LTB4 inhibitor and has a more potent activity than the reported LTA4 inhibitor RP64966. When tested with PMN cells, administration of SC-57461A significantly inhibited the synthesis of LT that induced by fMLP and PAF by acting on LTB4-BLTR1 interaction [3].In fasted CD rat model of calcium ionophore A23187-induced eicosanoid production, oral administration of SC-57461A showed effective inhibition on LTB4 with ED50 value of 0.3-1.0 mg/kg. When tested with AA-induced edema on the ear, oral administration of SC-57461A resulted in markedly inhibition of edema at doses of 0.8, 4 and 20 mg/kg [1].It is also been reported that SC-57461A inhibited LTB4A with Ki values of 23 nM and 27 nM for epoxide hydrolase and aminopeptidase, respectively [1].References: [1].
