体外研究(In Vitro)
体外研究活性	R406是ATP竞争性Syk抑制剂，K_i为30 nM。在不同细胞中R406选择性抑制 Syk依赖的信号通路，EC50为33 nM 到171 nM,比作用于 Syk非依赖性通路效果高很多。^[1] R406作用于多种弥漫性巨大细胞淋巴瘤，抑制细胞增殖，EC50 为0.8 μM 到 8.1 μM。1 μM 或 4 μM R406处理DLBCL细胞系，诱导caspases 9 和3激活, 而不激活caspase 8，导致大部分细胞凋亡。用R406预处理B细胞受体(BCR)交联的对R406 敏感的DLBCLs，完全抑制 SYK525/526磷酸化和BLNK依赖SYK的磷酸化。^[2] R406有效降低MMP-9 mRNA水平，处理24和48小时，比对照组分别降低2.8和4.3倍,并降低RL细胞侵袭能力。^[3]
激酶实验	体外荧光偏振激酶实验
激酶实验	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 乙酰化BGG)中稀释到DMSO浓度为1%。室温下加入溶于激酶buffer的ATP和底物, 终DMSO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，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20 μL 含EDTA/磷酸抗体(1X)/荧光蛋白磷酸肽示踪(0.5X)（在FP稀释buffer中稀释）的PTK猝灭混合物终止反应。然后实验板在室温下黑暗温育30分钟，然后在Polarion荧光偏振读数板上进行读数。R406按11种浓度进行平行实验，使用Prism GraphPad 软件通过回归曲线分析进行曲线拟合而测定IC50值。

	方法	用连续稀释的R406 (0.3, 0.6, 1.25, 2.5, 或5 μM) 处理DLBCL 细胞系72 或 96小时。通过MTT实验测定细胞增殖，使用annexin V–FITC/碘化丙啶(PI)染色测定细胞凋亡。为了测定caspase9，8和3，细胞裂解，通过聚丙烯酰胺凝胶电泳（PAGE）进行大小分离，然后进行免疫印迹。

体内研究(In Vivo)
体内研究活性	R406有效作用于多种免疫系统紊乱的动物模型。R406口服给药患免疫复合物导致炎症反应的小鼠，显著抑制皮肤反向被动Arthus反应，按1 mg/kg和 5 mg/kg剂量处理, 与对照组相比则抑制分别为72% 和86%。R406按 10 mg/kg 剂量处理用胶原抗体处理的鼠，显著降低炎症和肿胀, 使渐进性关节炎降低到较低水平，且延迟发病，且作用于K/BxN血清转移小鼠模型，降低临床关节炎达 50% 。^[1]
