| 体外研究活性 | R935788是R406亚甲基磷酸言药物前体,可在体内快速转化为R406。R406(R935788的活性形式)选择性抑制Syk依赖性信号，EC50为33 nM 到171 nM,比作用于Syk非依赖性通路更有效。[1] R406抑制多种弥散性大B细胞淋巴瘤(DLBCL)细胞系增殖，EC50为 0.8 μM到8.1 μM。[2] R406 处理，降低BLNK, Akt, GSK-3, FOXO和ERK 磷酸化。此外, R406作用于TCL1白血病，完全抑制抗-IgM抗体诱导的BCR信号。尽管TCL1白血病中存在高水平的组成型激活的Syk，但是R406对白血病细胞没有选择毒性。[3] | |||

| R406在 DMSO中连续稀释，然后在激酶buffer(20 mM HEPES, pH 7.4, 5 mM MgCl2, 2 mM MnCl2, 1 mM DTT, 0.1 mg/mL 乙酰 BGG)中稀释到 1% DMSO。室温下，在激酶 buffer中加入ATP和底物，使DMSO 终浓度为0.2%。在含 5 μM HS1 肽底物和 4 μM ATP 的混合物中进行激酶反应，终体积为 20 μL，然后在激酶buffer中加入0.125 ng Syk 开始反应。反应在室温下进行40分钟。加入含EDTA/抗磷酸抗体/荧光磷酸示踪物（在FP 稀释 Buffer中稀释）的20 μL PTK淬灭混合物，反应终止。反应在室温下暗中反应30分钟，然后在Polarion 荧光偏振酶标仪上读数。通过与酪氨酸激酶实验试剂盒中的磷酸竞争剂竞争获得校准曲线，数据转换为磷酸数量。为了测定IC50，测定11种浓度R406，重复进行实验，使用 Prism GraphPad 软件，通过非线性回归分析进行曲线拟合。 | ||||

| 体内研究(In Vivo) | ||
| 体内研究活性 | 考虑到R406作用于小鼠的血浆半衰期短于 2小时，R935788分3次给药，每次间隔3小时，确保在每次给药期间Syk得到持续抑制，模仿作用于人类的较长血浆半衰期 (15小时)。尽管在体外细胞毒性作用相对温和，但是R935788在体内显著抑制白血病细胞增殖和存活，这与阻止抗原依赖性B细胞受体（BCR）的信号相关，而与抑制组成型Syk活性无关。R935788每天按80 mg/kg剂量处理小鼠，持续 18-21 天，有效抑制 TCL1-002, TCL1-551 和 TCL1-870肿瘤生长，在处理末期观察不到白血病 CD5+/B220+细胞，R935788显著延长处理鼠的寿命，平均寿命从 45/46天提高到170/172 天, 且在后期6个月的处理期间完全根除相当大比例的恶性细胞，且不会影响正常 B 淋巴细胞的产生。R935788治疗也诱导正常和恶性B细胞从脾脏和淋巴结中短暂迁移到外周血中，随后选择性抑制恶性B细胞生长。此外, R935788作用于Eμ-TCL1转基因小鼠，也有效作用于自发的TCL1白血病。[3] | |

问题 1:
What’s the difference between S2625 and S2206?
回答：
The differences between S2625 and S2206: 1. S2206 is more stable than S2625; 2. The water solubility of S2206 is better than S2625; 3. The absorption of S2206 is harder than S2625, so you need to test the suitable dosage if you use the product in animal assays; 4. The potency of S2206 and S2625 is similar.
