Background | It is a highly selective and reversible PKC inhibitor. |
Biological Activity | Bisindolylmaleimide I 是一种具有高度选择性, 细胞可渗透性和可逆性的 PKC抑制剂, Ki值为14 nM[1-2]。 |
IC50 | Bovine brain PKC:10nM (IC50) PKCβII:16nM (IC50) PKCβI:17nM (IC50) PKCα:20nM (IC50) PKCγ:20nM (IC50) FDGFR:65μM (IC50) [1-2] |
In Vitro | 与五种不同的蛋白激酶相比,双吲哚基马来酰亚胺I是ATP的竞争性抑制剂(Ki = 14nM)并且对PKC显示出高选择性。 GF 109203X有效地阻止PKC介导的血小板中Mr = 47,000蛋白质和Swiss 3T3细胞中Mr = 80,000蛋白质的磷酸化。 GF 109203X抑制胶原蛋白和α-凝血酶诱导的血小板聚集以及胶原蛋白触发的ATP分泌。但是,不修改依赖于ADP的可逆聚合。在Swiss 3T3成纤维细胞中,GF 109203X逆转佛波醇12,13-二丁酸诱导的表皮生长因子结合的抑制,并阻止[3H]胸苷掺入DNA,只有当这是由激活PKC的生长促进剂引发的[1]。 |
In Vivo | 使用闭合的颅窗体内显微镜技术监测软膜小动脉直径变化。当比较DM与ND或TR大鼠时,与SNS相关的软脑膜小动脉延迟反应降低了45%。此外,局部KCl和NS1619的软膜小动脉扩张在DM大鼠中大大减弱,但在ND或TR动物中没有。通过将双吲哚基马来酰亚胺I急性应用于脑表面,可以完全恢复这些反应。 PKC抑制剂对正常血糖和TR动物的血管反应没有影响。总之,神经血管耦合的DM相关慢性损伤可以通过PKC-α/β/γ抑制剂容易地逆转或通过胰岛移植来预防。特异性PCK同种型(α/β/γ)被认为与高血糖所见的神经血管解偶联机械相关[2]。 |
Animal Experiment | 本研究使用三组Lewis大鼠:1)正常血糖4-6个月的非糖尿病对照组(ND组,n = 11); 2)链脲佐菌素(STZ)治疗的糖尿病大鼠(6个月大,STZ后4个月)(DM组,n = 6); 3)STZ治疗的糖尿病动物,在糖尿病模型建立后不久进行胰岛移植,在移植后100-110天进行研究(TR组,n = 7)[2]。 |
Kinase Experiment | 通过测量从[γ-32Pi] ATP转移至富含赖氨酸的组蛋白III-s的32Pi来排列PKC。反应混合物(80μL)含有50mM Tris-HCl,pH 7.4。 100μMCaCl2,10mM MgCl2,37.5μg/ mL组蛋白III型,10μM[γ-32Pi] ATP(1250cpm / pmol),31μM牛脑磷脂酰丝氨酸和0.5μM1,2α-二油酰甘油。将15μL纯化的PKC(测定中的最终浓度0.38μg/ mL)加入到孵育混合物中。 10分钟后,加入30μL酪蛋白30mg / mL和0.9mL 12%三氯乙酸[1]终止反应。 |
