potent previously known polo-like kinase 1 (Plk1) polo-box domain (PBD) binding inhibitors. This improved binding may result by accessing a newly identified auxiliary region proximal to a key hydrophobic cryptic pocket on the surface of the protein. Our findings could have general applicability to the design of PBD-binding antagonists.
通过涉及使用基于肟连接的策略初步筛选一组87个醛的过程,我们能够实现比最有效的先前已知的polo-like激酶1(Plk1)polo-box的亲和力提高数倍。域(PBD)结合抑制剂。这种改善的结合可以通过接近蛋白质表面上关键疏水隐窝的新近识别出的辅助区域来实现。我们的发现可能普遍适用于PBD结合拮抗剂的设计。
