Water networks within kinase inhibitor design and more widely within drug discovery are generally poorly understood. The successful targeting of these networks prospectively has great promise for all facets of inhibitor design, including potency and selectivity for the target. Herein, we describe the design and testing of a targeted library of 4‐anilinoquin(az)olines for use as inhibitors of cyclin G‐associated kinase (GAK). GAK cellular target engagement assays, ATP binding‐site modelling and extensive water mapping provide a clear route to access potent inhibitors for GAK and beyond.

针对细胞周期蛋白G关联激酶（GAK）中的水网络与4-苯胺基喹啉（az）碱抑制剂的结合。

人们普遍对激酶抑制剂设计中的水网络以及药物发现中的水网络知之甚少。这些网络的成功靶向有望为抑制剂设计的所有方面带来广阔前景，包括对靶标的效力和选择性。在本文中，我们描述了针对4-苯胺基喹啉（az）的靶向库的设计和测试，该库可用作细胞周期蛋白G相关激酶（GAK）的抑制剂。GAK细胞靶标参与分析，ATP结合位点建模和广泛的水作图提供了获得有效的GAK抑制剂及其他抑制剂的清晰途径。
