dependent tumors. 2-Aryl-quinazolinones were identified and optimized into potent tankyrase inhibitors through SAR exploration around the quinazolinone core and the 4'-position of the phenyl residue. These efforts were supported by analysis of TNKS X-ray and WaterMap structures and resulted in compound 5k, a potent, selective tankyrase inhibitor with favorable pharmacokinetic properties. The X-ray structure
Tankyrases 1和2(TNKS1 / 2)是有前途的药理学目标,最近对Wnt途径依赖性肿瘤的抗癌治疗产生了兴趣。通过围绕
喹唑啉酮核心和苯基残基的4'-位置的
SAR鉴定,确定了2-芳基
喹唑啉酮并将其优化为有效的坦科聚合酶
抑制剂。这些努力得到了TNKS X射线和WaterMap结构的分析的支持,并产生了化合物5k,它是一种具有良好药代动力学特性的有效的选择性坦古拉酶
抑制剂。解决了5k与TNKS1配合使用的X射线结构,并证实了设计假设。在体内结直肠异种移植模型中证明了该化合物对Wnt途径活性的调节。
