The Ser/Thr kinase Akt (Protein Kinase B/PKB) is a master switch in cellular signal transduction pathways. Its downstream signaling influences cell proliferation, cell growth, and apoptosis, rendering Akt a prominent drug target. The unique activation mechanism of Akt involves a change of the relative orientation of its N-terminal pleckstrin homology (PH) and the kinase domain and makes this kinase suitable for highly specific allosteric modulation. Here we present a unique set of crystal structures of covalent-allosteric interdomain inhibitors in complex with full-length Akt and report the structure-based design, synthesis, biological and pharmacological evaluation of a focused library of these innovative inhibitors.
丝氨酸/苏氨酸激酶Akt（蛋白激酶B/PKB）是细胞信号转导通路中的一个主控开关。其下游信号传导影响细胞增殖、细胞生长和细胞凋亡，使Akt成为一个重要的药物靶点。Akt独特的激活机制涉及其N端普列克底物蛋白同源性（PH）结构域和激酶结构域相对取向的改变，使得该激酶适合进行高度特异性的变构调节。在此，我们展示了一组与全长Akt复合的共价变构域间抑制剂的独特晶体结构，并报告了基于这些创新抑制剂的聚焦文库的结构设计、合成、生物学和药理学评估。
