IC50: 129 nM (ALK4), 47 nM (ALK5) |
| 体外研究 | SB-505124证明在高达100μM的浓度下48小时对肾上皮A498细胞没有毒性。 505124抑制密切相关的ALK4,IC50值为129±11 nM(比ALK5敏感性低约2.5倍),但在高达10μM的浓度下不抑制ALK2。 SB-505124(1μM)以浓度依赖性方式抑制TGF-β诱导的所有这三种细胞系中Smad2的磷酸化。 SB-505124(1或5μM)有效抑制TGF-β诱导的JNK/SAP,细胞外信号调节激酶1/2和p38的激活,尽管这些细胞中的激活模式不同[1]。 SB-505124(10μM)在体外损害Smad2磷酸化和CTGF和α-SMA表达[2]。 SB-505124通过免疫荧光观察抑制CTGF和α-SMA。在GFS期间从施用SB-505124的眼睛切下的外植体中的细胞向外生长是稳健的,而用MMC处理的那些生长较差[3]。 |
| 激酶实验 | 简而言之，磷酸-p38在4℃下用固定的磷-p38抗体从200μg细胞裂解物中免疫沉淀过夜。使用2μgATF-2融合蛋白作为底物并添加200μMATP来测量p38激酶活性。在30℃温育30分钟后，用LaemmLi样品缓冲液终止反应，将蛋白质煮沸并通过10％SDS-聚丙烯酰胺凝胶电泳分离，转移到硝酸纤维素膜上，并用磷酸-ATF-2抗体进行免疫印迹。 。 |
| 细胞实验 | 如前所述或通过使用改良的四唑盐WST-1测量细胞活力。将大约2000个细胞接种在96孔培养皿中的100μL0.2％FBS无酚红培养基中过夜。将细胞用50μL的SB-505124（达到所示的最终浓度）处理30分钟，然后用或不用TGF-β1和TNF-α处理至终体积为200μL。通过在37℃下将每个孔与10μLWST-1孵育3小时，在指定的时间点测量细胞生长。代谢活性细胞将WST-1切割成水溶性甲,,其用酶联免疫吸附测定板读数器直接定量。每个实验至少进行两次，每个细胞系的处理一式三份进行。 |
