A novel strategy employing cyclohexyl spectator ligands in Stille cross-coupling reactions has been developed as a general solution to the long-standing challenge of conducting stereospecific cross-coupling reactions at nitrogen-containing stereocenters. This method enables direct access to enantioenriched products that are difficult (or impossible) to obtain via alternative preparative methods. Selective

transcription following activation of WNT signaling. Multiple lines of evidence suggest CDK8 may act as an oncogene in the development of colorectalcancer. Here we describe the successful optimization of an imidazo-thiadiazole series of CDK8 inhibitors that was identified in a high-throughput screening campaign and further progressed by structure-based design. In several optimization cycles, we improved
介导复合物相关的细胞周期蛋白依赖性激酶CDK8在激活WNT信号后调节β-catenin依赖性转录。多方面证据表明CDK8可能在结直肠癌的发展中起癌基因的作用。在这里,我们描述了在高通量筛选活动中确定并通过基于结构的设计进一步发展的CDK8咪唑-噻二唑系列CDK8抑制剂的成功优化。在几个优化周期中,我们改善了微粒体的稳定性,效能和激酶选择性。最初的咪唑并噻二唑支架被3-甲基-1 H-吡唑并[3,4- b ]-吡啶取代,得到化合物25(MSC2530818)具有优异的激酶选择性,生化和细胞效价,微粒体稳定性,并且可口服生物利用。此外,我们证明了磷酸化STAT1的调节,CDK8活性的药效生物标记物,以及口服给药后在APC突变体SW620人结肠直肠癌异种移植模型中的肿瘤生长抑制作用。化合物25表现出合适的潜能和选择性,可以进入临床前体内功效和安全性研究。
