palmiteolate pocket with key interactions being aromatic stacking and a water mediated hydrogen bond to the oxyanion hole. These N-acyl indolines 4 will be useful tools for use in vitro studies to investigate the role of Notum in disease models, especially when paired with a structurally related covalent inhibitor (e.g. 4w and 2a). Overall, this study highlights the designed switch from covalent to non-covalent
N-酰基二氢吲哚4是有效的非共价 Notum 抑制剂,由共价虚拟筛选命中2a开发而成。先导化合物合成简单,在生化 Notum-OPTS 测定中实现了优异的效力,并在基于细胞的 TCF/LEF 报告基因测定中恢复了 Wnt 信号传导。多个高分辨率X射线结构建立了这些抑制剂的共同结合模式,二氢吲哚结合在棕榈醇酸袋的中心,关键相互作用是芳族堆积和水介导的与氧阴离子孔的氢键。这些N -酰基二氢吲哚4将成为体外研究的有用工具,用于研究 Notum 在疾病模型中的作用,特别是与结构相关的共价抑制剂(例如4w和2a)配对时。总的来说,这项研究强调了从共价到非共价 Notum 抑制剂的设计转换,因此说明了命中生成和目标抑制的补充方法。
