~100 nM (IC50, LTB4 binds to guinea pig lung membranes)
体外研究(In Vitro)
LY255283 competitively reduces conlractilc responses of lung parcnchyma to LTB, (pA2 = 7.2).
LY255283 (10 μM, 7 days) significantly suppresses the invasiveness of highly aggressive 253 J-BV bladder cancer cells.

Cell Viability Assay
Cell Line:
253 J-BV cells.
Concentration:
5 or 10 μM.
Incubation Time:
7 days.
Result:
Inhibition of BLT2 signaling attenuates aggressive migration by 253 J-BV cells.
体内研究(In Vivo)
LY255283 (3, 30 mg/kg) ameliorates lipopolysaccharide-induced ARDS in pigs, possibly by blocking the recruitment of activated PMNs into alveoli in a dose-dependent fashion.
LY255283 (2.5 mg/kg, ip) inhibits transitional cell carcinoma metastasis in mice models. The result suggests that a BLT2–Nox–ROS–NF–κB cascade plays a critical role in bladder cancer invasion and metastasis.
Medlife has not independently confirmed the accuracy of these methods. They are for reference only.
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.
