potent, and kinome selective inhibitors of transforming growth factor β-activated kinase 1 (TAK1). The target was subjected to a DNA-encoded chemical library (DECL) screen. After hit analysis a cluster of compounds was identified, which was based on a central pyrrole-2,4-1H-dicarboxamide scaffold, showing remarkable kinome selectivity. A scaffold-hop to the corresponding imidazole resulted in increased biochemical
在这里,我们报告了 2,4-1 H-咪唑甲酰胺作为转化生长因子 β 活化激酶 1 (TAK1) 的新型、生化有效和激酶组选择性抑制剂的发现。对目标进行 DNA 编码的化学文库 (DECL) 筛选。命中分析后,确定了一组化合物,其基于中心 pyrrole-2,4-1 H-二甲酰胺支架,显示出显着的激酶组选择性。与相应咪唑的支架跳跃导致生化效力增加。接下来,X 射线晶体学显示与其他 TAK1 抑制剂相比具有明显的结合模式。发现苄酰胺相对于核心铰链结合咪唑呈垂直方向。此外,在激酶铰链区观察到不寻常的酰胺翻转。使用基于结构的药物设计 (SBDD),吡咯烷酰胺和甘氨酸的关键取代导致生化效力显着提高。
