BI-882370（0.9-6000 nM；3 天）的 EC50 范围为 1-10 nM，可抑制具有 BRAF 突变的人类黑色素瘤和结直肠癌细胞的增殖[1]。 BI 882370（0.1-100 nM，0.1-3000 nM；2 小时）降低 BRAFV600E 突变 A375 细胞中 p-MEK1/2、p-ERK1/2 和细胞周期蛋白 D1/D2 的表达；在 WT BRO 细胞中，它会增加 ERK1/2 的磷酸化并磷酸化 MEK1/2 (3–300 nM)[1]。在 BRAFV600E 突变 A375 细胞中，浓度为 1 nM 或更高的 BI 882370（0.1-100 nM、0.1-3000 nM；24 小时）可抑制细胞周期蛋白 D1/D2 表达并增加 Kip1/p27 表达。 WT BRO 细胞中细胞周期蛋白 D1/D2 或 Kip1/p27 的表达不受影响。

BI-882370（口服给药；25 mg/kg、50 mg/kg；每天两次；2 周）在多种结直肠和 BRAF 突变黑色素瘤小鼠模型中比 Vemurafenib、Dabrafenib 或 Trametinib 更有效[1]。 BI-882370（口服；25 mg/kg；每天两次；40 天）在三周内出现耐药性，但曲美替尼辅助二线治疗五周并未显示出耐药性[1]。通过临床化学、血液学、病理学和毒理基因组学测量，BI-882370（口服；60 mg/kg；每天一次；2 周）显示对大鼠没有毒性[1]。

Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)
*Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution.
Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline)
Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil)
Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).

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;
