LY255283 是LTB4受体(BLT2)的拮抗剂,其抑制 [3H]LTB4结合到豚鼠肺膜的IC50值约为 100 nM。
生物活性 | LY255283 is aLTB4receptor (BLT2)antagonist, with anIC50of ~100 nM for [3H]LTB4binding to guinea pig lung membranes[1][2][3][4]. |
IC50& Target[2] | LTB4 ~100 nM (IC50, LTB4binds to guinea pig lung membranes) |

体外研究 (In Vitro) | LY255283 competitively 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. |

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[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. |
