| Description | LY255283 is a LTB4 receptor (BLT2) antagonist, with an IC50 of ~100 nM for [3H]LTB4 binding to guinea pig lung membranes[1][2][3][4]. |

| In Vitro | LY255283 compctitively reduces conlractilc responses of lung parcnchyma to LTB, (pA2 = 7.2)[2]. LY255283 (10 μM, 7 days) significantly suppresses the invasiveness of highly aggressive 253 J-BV bladder cancer cells[4]. Cell Viability Assay[4] 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. | 
| In Vivo | LY255283 (3, 30 mg/kg) ameliorated lipopolysaccharide-induced ARDS in pigs, possibly by blocking the recruitment of activated PMNs into alveoli in a dose-dependent fashion[3]. 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[4]. Animal Model: Mice (253 J-BV cells injected)[4]. 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. |
