Src kinase, a prototype member of the Src family of kinases (SFKs), is over-expressed in various human tumors, and has become a target for anticancer drug design. In this perspective, a series of eighteen 2-pyridone derivatives were synthesized and evaluated for their c-Src kinase inhibitory activity. Among them, eight compounds exhibited c-Src kinase inhibitory activity with IC50 value of less than
Src激酶是Src激酶家族(SFKs)的原型成员,在各种人类肿瘤中均过表达,已成为抗癌药物设计的目标。从这个角度出发,合成了一系列十八个2-吡啶酮衍生物,并评估了它们的c-Src激酶抑制活性。其中,八种化合物表现出c-Src激酶抑制活性,IC 50值小于25μM。化合物1- [2-(二甲基氨基)乙基] -5-(2-羟基-4-甲氧基苯甲酰基)吡啶-2(1H)-一(36)表现出最高的c-Src激酶抑制作用,IC 50值为12.5μM 。此外,化合物36的激酶抑制活性研究人员针对EGFR,MAPK和PDK进行了研究,但在最高测试浓度(300μM)下未观察到明显的活性。这些结果为进一步优化该支架以设计下一代2-吡啶酮衍生物作为候选Src激酶抑制剂提供了见识。
