  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.

  立体选择性合成顺式1,3-二取代的环丁基激酶抑制剂。

  摘要：

  描述了两种合成途径来制备一系列包含顺式-1,3-二取代的环丁烷的结构新颖的激酶抑制剂。第一种方法是将3-氨基环丁醇添加到1,4-二硝基咪唑5中，这是制备1的关键步骤，而第二种方法是将4-硝基咪唑18新颖地1,4-添加到原位生成的环丁烯酮17中反应。这样就可以进行立体选择性和较短的合成，从而避免了使用潜在爆炸性的1,4-二硝基咪唑5。

  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.
