蛋白激酶是一大类具有多种生物学作用的酶,其中许多与多种疾病有关,包括癌症和新型冠状病毒感染COVID-19。因此,开发选择性靶向每种激酶的化学探针具有极大的意义。用ATP竞争性抑制剂抑制蛋白激酶历来是最广泛使用的方法。然而,由于ATP位点的高度保守结构,鉴定真正选择性的化学探针是具有挑战性的。在这篇综述中,我们使用的丝氨酸/苏氨酸激酶CK 2作为一个例子,以突出有效的和选择性的化学探针开发的历史挑战,以及在该领域的最新进展和替代战略,旨在克服这些问题。用于CK 2的方法可应用于一系列蛋白激酶,以帮助发现化学探针,以进一步了解每种激酶的生物学,对药物开发具有广泛的影响。
Protein kinases are a large class of enzymes with numerous biological roles and many have been implicated in a vast array of diseases, including cancer and the novel coronavirus infection COVID-19. Thus, the development of chemical probes to selectively target each kinase is of great interest. Inhibition of protein kinases with ATP-competitive inhibitors has historically been the most widely used method. However, due to the highly conserved structures of ATP-sites, the identification of truly selective chemical probes is challenging. In this review, we use the Ser/Thr kinase CK2 as an example to highlight the historical challenges in effective and selective chemical probe development, alongside recent advances in the field and alternative strategies aiming to overcome these problems. The methods utilised for CK2 can be applied to an array of protein kinases to aid in the discovery of chemical probes to further understand each kinase’s biology, with wide-reaching implications for drug development.
