inhibitors of Aurora A kinase and VEGF receptor kinases. Crystal structures of two representatives of the new chemotype in complex with Aurora A showed the ligand orientation in the ATP binding pocket and provided the basis for rational structural modifications. Congeners with attached sulfamide substituents retained Aurora A inhibitory activity. In vitro screening of two members of the new kinase inhibitor
尽管蛋白激酶的过表达和过度活跃是导致多种人类癌症的原因,但目前被批准用作抗癌药物的蛋白激酶抑制剂仅能解决其中几种酶的问题。为了确定解决替代蛋白激酶的新化学型,将已知的PLK1 / VEGF-R2抑制剂类别的基本结构进行了正式解剖并重新组装。合成了所得的7-(2-苯胺基嘧啶丁-4-基)-1-苯并ze庚因-2-酮,并证明是Aurora A激酶和VEGF受体激酶的双重抑制剂。与Aurora A配合的新化学型的两个代表的晶体结构显示了ATP结合口袋中的配体取向,并为合理的结构修饰提供了基础。具有连接的磺酰胺取代基的同类物保留了Aurora A的抑制活性。
