Hersperadin是Aurora B的ATP竞争性小分子抑制剂,是与细胞分裂有关的三个Aurora激酶家族成员之一,IC50值250 nM,Hersperadin的磺胺群插入到Aurora B催化位点的ATP结合处并延伸到邻近的疏水腔里。已发现Hersperadin可阻止AuroraB的磷酸化,Aurora B的Ser-10磷酸化在有丝分裂过程中作为一个生物标志物,Hersperadin抑制染色体联合和分离的IC50值为40 nM。

体外实验 [1]: | |
激酶实验 |
Hesperadin是插入Aurora A和B的ATP结合口袋的抑制剂。它抑制Aurora B的IC50为250 nM,但对于Cdk1 /细胞周期蛋白B或Cdk2 / 细胞周期蛋白E的IC50值在1.2μM至> 10μM的范围内。在浓度为200nM的情况下,Hesperadin将免疫沉淀的激酶的活性降低到背景水平。 |
细胞实验[2]: | |
细胞系 |
HeLa细胞 |
溶解方法 |
该化合物在DMSO中的溶解度>25.9mg/mL。为了获得更高的浓度,可以将离心管在37℃加热10分钟和/或在超声波浴中震荡一段时间。原液可以在-20℃以下储存几个月。 |
反应条件 |
50 nM; 2 h |
应用 |
在HeLa细胞中,Hesperadin停止细胞增殖,但不停止生长,并且在6天的时间内,细胞直径增加了超过七倍(从20到150μm)。细胞获得与多倍体相关的扩大的裂核,在第3天达到32C DNA含量。Hesperadin引起有丝分裂和细胞分裂的缺陷。 |
