  develop novel nonphthalimide CRBN binders. These efforts led to the discovery of conformationally locked benzamide-type derivatives that replicate the interactions of the natural CRBN degron, exhibit enhanced chemical stability, and display a favorable selectivity profile in terms of neosubstrate recruitment. The utility of the most potent ligands was demonstrated by their transformation into potent degraders

  沙利度胺、泊马度胺和来那度胺等免疫调节酰亚胺药物 (IMiD) 是蛋白水解靶向嵌合体 (PROTAC) 设计中最常见的 cereblon (CRBN) 招募剂。然而，这些 CRBN 配体会诱导 IMiD 新底物的降解，并且本质上不稳定，在温和条件下会水解降解。在这项工作中，我们同时优化了理化性质、稳定性、靶向亲和力和脱靶新底物调节特征，以开发新型非邻苯二甲酰亚胺 CRBN 粘合剂。这些努力导致了构象锁定苯甲酰胺型衍生物的发现，这些衍生物复制了天然 CRBN 降解决定子的相互作用，表现出增强的化学稳定性，并在新底物招募方面表现出良好的选择性。最有效的配体的效用通过它们转化为 BRD4 和 HDAC6 的有效降解剂而得到证明，其性能优于先前描述的参考 PROTAC。加上它们对 IKZF1/3 和 SALL4 的新生连接酶活性显着降低，这些配体为设计高选择性和有效的化学惰性邻近诱导化合物提供了机会。

  Proteolysis-targeting chimeras (PROTACs) is a paradigm shift for small-molecule drug discovery. However, limited E3 ubiquitin ligase ligands with cellular activity are available. In vitro binding assays involve the expression and purification of a large amount of proteins and they often yield ligands that are inactive in cell-based assays due to poor cell permeability, stability, and other reasons. Herein, we report the development of a practical and efficient cell-based target engagement assay to evaluate the binding affinity of a small library of cereblon ligands to its E3 ligase in cells. Selected cell-permeable E3 ligase ligands derived from this assay are then used to construct HDAC6 degraders with cellular protein degradation activity. Because the assay does not involve any genetic engineering, it is relatively easy to transfer from one cell type to a different one.
