GNE-495

MAP4K4 (IC50 = 3.7 nM)

GNE-495 是一种强效 MAP4K4 抑制剂，可以很好地促进血管生成。 GNE-495 表现出最低的身体稳定性、渗透性、有效的理想细胞平衡和 MAP4K4 吸附 [1]。

高剂量的 GNE-495（25 和 50 mg/kg）被腹腔注射给新生小鼠幼崽。在检查的每个物种中，GNE-495 都表现出良好的内部特性，包括低清除率、适度的终端半相衰减和适当的杠杆水平 (F=37–47%) [1]。

Rats, Mice and Pups
For the brain cassette study, three male Sprague-Dawley (SD) rats receive an intravenous (IV) bolus dose of six test substances (for example, GNE-495; 0.5 mg/kg). GNE-495 is injected intravenously in bolus doses of 1 mg/kg in female CD-1 mice for the mouse PK study. GNE-495 (5 mg/kg) is additionally injected intravenously (PO) into female CD-1 mice. The rat brain cassette PK is dosed at 2 mL/kg, and all other doses are administered at 5 mL/kg. Water and food are available to animals at all times, and they are not fasted before receiving a dose. Three blood samples (~60 μL) are taken from each mouse up to either 9 or 24 hours after the compound of interest is given. This is done using a serial sampling method, and it involves taking three blood samples from each mouse. After being mixed with K2EDTA and placed on ice or in a cold Kryorack immediately after collection, the blood is then centrifuged to separate the plasma. Blood samples are centrifuged for 10–15 minutes at 4°C while being spun at a speed of 1000-2000× g within an hour of being drawn. This process yields the plasma. The plasma samples are stored at -70 to -80°C until analysis. For neonate PK, 3-day-old CD1 pups are injected with 25 mg/kg and 50 mg/kg GNE-495. Blood samples are taken intraperitoneally at the times specified, retinas are taken one hour after the dose, snap frozen in liquid nitrogen, and kept at -80°C until analysis. The concentrations of plasma and retinal lysate are assessed using LC/MS/MS.

请根据您的实验动物和给药方式选择适当的溶解配方/方案：
1、请先配制澄清的储备液(如：用DMSO配置50 或 100 mg/mL母液(储备液));
2、取适量母液，按从左到右的顺序依次添加助溶剂，澄清后再加入下一助溶剂。以 下列配方为例说明 (注意此配方只用于说明，并不一定代表此产品 的实际溶解配方):
10% DMSO → 40% PEG300 → 5% Tween-80 → 45% ddH2O (或 saline);
假设最终工作液的体积为 1 mL, 浓度为5 mg/mL: 取 100 μL 50 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中，混合均匀/澄清；向上述体系中加入50 μL Tween-80，混合均匀/澄清；然后继续加入450 μL ddH2O (或 saline)定容至 1 mL；
3、溶剂前显示的百分比是指该溶剂在最终溶液/工作液中的体积所占比例;
4、 如产品在配制过程中出现沉淀/析出，可通过加热(≤50℃)或超声的方式助溶;
5、为保证最佳实验结果，工作液请现配现用！
6、如不确定怎么将母液配置成体内动物实验的工作液，请查看说明书或联系我们;
