生物活性
LY255283 是一種 leukotriene B4 (LTB4) receptor (BLT2) 的拮抗劑，可將 [3H]LTB4 從其在肺膜上的結(jié)合位點(diǎn)置換，pKi為7.0。靶點(diǎn)
| Target | Value |
|
BLT2
(Cell-free assay) | 7.0(pKi) |
體外研究
LY255283 competitively reduces conlractilc responses of lung parcnchyma to LTB, (pA
2
= 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. |
體內(nèi)研究
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.
| 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. |
