pursuit of developing a novel, potent, and selective cell division cycle 7 (Cdc7) inhibitor, we optimized the previously reported thieno[3,2-d]pyrimidinone analogue I showing time-dependent Cdc7 kinase inhibition and slow dissociation kinetics. These medicinal chemistry efforts led to the identification of compound 3d, which exhibited potent cellular activity, excellent kinase selectivity, and antitumor
在我们寻求开发新型,有效和选择性的细胞分裂周期7(Cdc7)抑制剂的过程中,我们优化了先前报道的Thieno [3,2-d]嘧啶酮类似物I,显示出时间依赖性Cdc7激酶抑制作用和缓慢的解离动力学。这些药物化学工作导致了对化合物3d的鉴定,该化合物在COLO205异种移植小鼠模型中表现出强大的细胞活性,出色的激酶选择性和抗肿瘤功效。但是,在3d的详细研究中出现了甲醛加合物形成的问题,这被认为是进一步发展的障碍。一种基于结构的方法来避免加合物的形成,最终发现了具有奎宁环部分作为临床前候选化合物的化合物11b(TAK-931)。本文的设计,综合,
