  通过虚拟筛选发现选择性Aurora A激酶抑制剂

  摘要：

  在这里，我们报告发现了Aurora A选择性抑制剂的发现，Aurora A是细胞分裂和潜在抗癌靶标的关键调节剂。我们使用原子类别扩展配体重叠评分（xLOS），这是我们小组最近开发的一种基于3D配体的虚拟筛选方法，用于选择437种参考激酶抑制剂的形状和药效基团类似物。生化筛选发现了两个激酶抑制剂系列中空前的支架抑制剂系列。其中一种已通过基于结构的设计成功优化为有效的Aurora A抑制剂（IC 50= 2 nM），对Aurora激酶具有非常高的激酶组选择性。该抑制剂将Aurora A锁定为非活性构象，并破坏与其激活蛋白TPX2的结合，从而削弱Aurora A在有丝分裂纺锤体上的定位并诱导细胞分裂缺陷。该表型可以通过抗抑制剂的Aurora A突变体挽救。此外，该抑制剂在细胞中不诱导Aurora B特异性作用。
