  Discovery of WD Repeat-Containing Protein 5 (WDR5)–MYC Inhibitors Using Fragment-Based Methods and Structure-Based Design

  摘要：

  The frequent deregulation of MYC and its elevated expression via multiple mechanisms drives cells to a tumorigenic state. Indeed, MYC is overexpressed in up to similar to 50% of human cancers and is considered a highly validated anticancer target. Recently, we discovered that WD repeat-containing protein 5 (WDR5) binds to MYC and is a critical cofactor required for the recruitment of MYC to its target genes and reported the first small molecule inhibitors of the WDR5-MYC interaction using structure-based design. These compounds display high binding affinity, but have poor physicochemical properties and are hence not suitable for in vivo studies. Herein, we conducted an NMR-based fragment screening to identify additional chemical matter and, using a structure-based approach, we merged a fragment hit with the previously reported sulfonamide series. Compounds in this series can disrupt the WDR5-MYC interaction in cells, and as a consequence, we observed a reduction of MYC localization to chromatin.

  基于结构的6-氯-4-氨基喹唑啉-2-羧酰胺衍生物作为有效和选择性p21活化激酶4（PAK4）抑制剂的设计。

  摘要：

  在本文中，我们报告了喹唑啉支架新型PAK4抑制剂的发现和表征。根据PAKs ATP结合袋的形状和化学组成，我们选择了2,4-二氨基喹唑啉系列抑制剂作为起始点。在X射线晶体学和基于结构的药物设计（SBDD）方法的指导下，设计和合成了一系列新型的4-氨基喹唑啉-2-羧酰胺PAK4抑制剂。优化了抑制剂的选择性，治疗效果和药物特性。最好的化合物之一31（CZh226），表现出显着的PAK4选择性（是PAK1的346倍）和有利的激酶选择性谱。此外，该化合物通过在体外调节PAK4定向的下游信号通路有效抑制A549肿瘤细胞的迁移和侵袭。综上所述，这些数据支持31作为PAK4靶向抗癌药物发现的先导化合物和II类PAK进一步生物学研究的有价值的研究探针的进一步开发。

  Utilizing structure-based drug design, a 4-aminoimidazole heterocyclic core was synthesized as a replacement for a 2-aminothiazole due to potential metabolically mediated toxicity. The synthetic route utilized allowed for ready synthesis of 1-substituted-4-aminoimidazoles. SAR exploration resulted in the identification of a novel cis-substituted cyclobutyl group that gave improved enzyme and cellular potency against cdk5/p25 with up to 30-fold selectivity over cdk2/cyclin E.
