Herein, we describe the discovery and optimization of an arylpyridone series as Cbl-binhibitors by structure-based drug discovery to afford compound 31. This compound binds to Cbl-b with an IC50 value of 30 nM and induces IL-2 production in T-cells with an EC50 value of 230 nM. Compound 31 also shows robust intracellular target engagement demonstrated through inhibition of Cbl-b autoubiquitination, inhibition
Casitas B 淋巴瘤原癌基因-b (Cbl-b) 是环指 E3 泛素连接酶 Cbl 家族的成员,已被证明在调节效应 T 细胞功能中发挥核心作用。使用基因靶向方法的多项研究提供了直接证据,表明 Cbl-b 通过泛素介导的蛋白质调节负向调节 T、B 和 NK 细胞活化。因此,抑制 Cbl-b 连接酶活性可以导致免疫激活,并在免疫肿瘤学中具有治疗潜力。在此,我们描述了通过基于结构的药物发现来发现和优化作为Cbl-b抑制剂的芳基吡啶酮系列以提供化合物31 。该化合物与 Cbl-b 结合,IC 50值为 30 nM,并诱导 T 细胞产生 IL-2,EC 50值为 230 nM。化合物31还显示出强大的细胞内靶标参与作用,这通过抑制 Cbl-b 自身泛素化、抑制泛素向 ZAP70 的转移以及 TCR 轴内下游信号磷酸化的细胞调节来证明。
