Naphthyridine-based inhibitors were synthesized to yield a potent and cell-active inhibitor of casein kinase 2 (CK2). Compound selectively inhibits CK2α and CK2α' when profiled broadly, thereby making it an exquisitely selective chemical probe for CK2. A negative control that is structurally related but lacks a key hinge-binding nitrogen () was designed on the basis of structural studies. Compound does not bind CK2α or CK2α' in cells and demonstrates excellent kinome-wide selectivity. Differential anticancer activity was observed when compound was profiled alongside a structurally distinct CK2 chemical probe: SGC-CK2-1. This naphthyridine-based chemical probe () represents one of the best available small molecule tools with which to interrogate biology mediated by CK2.
合成了基于萘啶的抑制剂，以产生一种有效的、具有细胞活性的酪蛋白激酶2（CK2）抑制剂。该化合物在广泛分析时选择性抑制CK2α和CK2α'，因此使其成为CK2的一种高度选择性的化学探针。基于结构研究设计了一种结构相关但缺少关键铰链结合氮（）的阴性对照。化合物在细胞中不结合CK2α或CK2α'，并表现出优异的全激酶组选择性。当化合物与结构不同的CK2化学探针SGC-CK2-1一起分析时，观察到了不同的抗癌活性。这种基于萘啶的化学探针（）是用于研究由CK2介导的生物学的最佳可用小分子工具之一。
