Design and synthesis of pyridine–pyrazolopyridine-based inhibitors of protein kinase B/Akt
摘要:
Thr-211 is one of three different amino acid residues in the kinase domain of protein kinase B/Akt as compared to protein kinase A (PKA), a closely related analog in the same AGC family. In an attempt to improve the potency and selectivity of our indazole-pyridine series of Akt inhibitors over PKA, efforts have focused on the incorporation of a chemical functionality to interact with the hydroxy group of Thr-211. Several substituents including an oxygen anion, amino, and nitro groups have been introduced at the C-6 position of the indazole scaffold, leading to a significant drop in Akt potency. Incorporation of a nitrogen atom into the phenyl ring at the same position (i.e., 9f) maintained the Akt activity and, in some cases, improved the selectivity over PKA. The structure-activity relationships of the new pyridine-pyrazolopyridine series of Akt inhibitors and their structural features when bound to PKA are also discussed. (c) 2007 Elsevier Ltd.

Mutations in oncogenes and tumor suppressors contribute to the development and progression of cancer. The present disclosure describes compounds and methods that restore DNA binding affinity of p53 mutants. The compounds of the present disclosure can bind to mutant p53 and restore the ability of the p53 mutant to bind DNA and activate downstream effectors involved in tumor suppression. The disclosed compounds can be used to reduce the progression of cancers that contain a p53 mutation.
Compounds disclosed herein including compounds of formula I′:
and salts thereof are provided. Pharmaceutical compositions comprising compounds disclosed herein, processes for preparing compounds disclosed herein, intermediates useful for preparing compounds disclosed herein and therapeutic methods for treating an HIV infection using compounds disclosed herein are also provided.

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。
