design, synthesis, and structure-activity relationship of 5-anilinopyrazolo[1,5-a]pyrimidine inhibitors of CK2 kinase. Property-based optimization of early leads using the 7-oxetan-3-yl amino group led to a series of matched molecular pairs with lower lipophilicity, decreased affinity for human plasma proteins, and reduced binding to the hERG ion channel. Agents in this study were shown to modulate
在这封信中,我们描述了CK2激酶的5-苯胺基吡唑并[1,5-a]嘧啶抑制剂的设计,合成和构效关系。使用7-氧杂环丁-3-基氨基基团对基于先导的属性进行优化,可得到一系列匹配的分子对,这些亲和力降低,亲脂性降低,对人血浆蛋白的亲和力降低,与hERG离子通道的结合降低。这项研究的药物在体外和体内均显示出可调节pAKT(S129)(CK2的直接底物),并且在鼠DLD-1异种移植物中口服给药时表现出肿瘤生长抑制作用。
