LY255283 is a LTB4 receptor (BLT2) antagonist, with an IC50 of ~100 nM for [3H]LTB4 binding to guinea pig lung membranes.

体内研究:
LY255283 (3,30 mg/kg) 可改善猪体内脂多糖诱导的 ARDS,这可能是通过以剂量依赖性方式阻断活化的 PMN 募集到肺泡中。 LY255283 (2.5 mg/kg,ip) 在小鼠模型中抑制移行细胞癌转移。结果表明,BLT2-Nox-ROS-NF-κB级联在膀胱癌侵袭和转移中起关键作用。Animal Model:Mice (253 J-BV cells injected).
Dosage:2.5 mg/kg.
Administration:IP injected 3 and 5 days after injection of cells.
Result:By 12 weeks after injection, in mice treated with LY255283 only 0-3 nodules formed per lung, and histological analysis confirmed that the number of micrometastatic lesions was markedly reduced.
