背景说明 |
是一种 ATP 竞争性的选择性 p70S6K 抑制剂。 |
生物活性 |
LY-2584702 tosylate salt is a selective ATP competitive inhibitor of p70S6K with an IC50 of 4 nM. In S6K1 enzyme assay, the IC50 of LY-2584702 is 2 nM.[1-3] |
In Vitro |
LY-2584702 tosylate salt (LY2584702) 抑制 HCT116 结肠癌细胞中 S6 核糖体蛋白 (pS6) 的磷酸化,IC50 为 0.1-0.24 μM[1]。 在 S6K1 酶测定中,LY-2584702 tosylate salt (LY2584702) 的 IC50 为 2 nM。对于细胞中的 pS6 抑制,IC50=100 nM。LY-2584702 tosylate salt 在高浓度下对 S6K 相关激酶 MSK2 和 RSK 具有一定活性 (酶法 IC50=58-176 nM)。LY-2584702 tosylate salt 以剂量依赖性方式抑制 EOMA 细胞中的 S6K 活性,这由其下游效应子 S6 的磷酸化决定[2]。 A549 的增殖被 LY-2584702 tosylate salt (LY2584702) 以 0.1 μM 处理 24 小时以上显著抑制 (P[3]。 |
In Vivo |
LY-2584702 tosylate salt 在 U87MG 胶质母细胞瘤和 HCT116 结肠癌异种移植模型中以 2.5 mg/kg 每天两次 (BID) 和 12.5 mg/kg BID 两种剂量水平显示出显著的单药疗效。在 HCT116 结肠癌异种移植模型中,LY-2584702 tosylate salt 在 TMED50 (阈值最小有效剂量 50%) (2.3 mg/kg) 和 TMED90 (10 mg/kg) 下表现出统计学显著的肿瘤生长减少[1]。 为了检查 S6K 在体内的作用,将表达 shAkt3 的 EOMA 细胞植入 nu/nu 小鼠,然后用 LY-2584702 tosylate salt 或雷帕霉素处理 14 天。对 14 天后取出的肿瘤进行的分析表明,LY-2584702 tosylate salt 几乎与雷帕霉素一样有效地抑制 S6 磷酸化。与 pLKO 相比,Akt3 的缺失会增加肿瘤生长。LY-2584702 tosylate salt 单独处理不会显著影响 pLKO 肿瘤的生长。然而,LY-2584702 tosylate salt 显著降低了 shAkt3肿瘤的生长[2]。 |
细胞实验 |
LY-2584702 is fully dissolved in 20 mL 10% DMSO and reserved at -80°C. When conducted the experiments in vitro, LY-2584702 is further diluted in 0.5% Tween 80, 5% propylene glycol and 30% PEG400 to reach different DMSO concentrations of 0.1 μM, 0.2 μM, 0.6 μM, and 1.0 μM. Cell Counting Kit-8 (CCK-8) is used to measure the cells proliferation in vitro. Cell lines A549 and SK-MES-1 treated by LY-2584702 for 24 h with different concentrations are seeded in 96-well plates at a density of 5×103 per well, with six repeats. DMSO treated, or in other words, the concentration of LY-2584702 of 0 is used as negative control. Cells absorbance at 450 nm is detected every 24 h after seeding to measure the proliferative activities[3]. |
动物实验 |
Mice[2]LY-2584702 is prepared in 0.25% Tween-80 and 0.05% antifoam, and administered orally to mice (12.5 mg/kg twice daily). EOMA cells (0.3×106) are injected subcutaneously in 6- to 8-week-old nu/nu female mice (2 sites/mouse, 4-5 mice/group). Tumor size is measured daily. For drug treatment, when tumors reach 0.01 cm3 in size, the animals are treated with vehicle control or LY-2584702 (12.5 mg/kg twice daily, oral dosing). Tumor size is measured every 3 to 4 days[2]. |
