The present invention provides compounds of formula I
and pharmaceutically acceptable salts thereof.
The formula I compounds inhibit tyrosine kinase activity of growth factor receptors such as HER1, HER2 and HER4 thereby making them useful as antiproliferative agents. The formula I compounds are also useful for the treatment of other diseases associated with signal transduction pathways operating through growth factor receptors.
本发明提供了式 I 的化合物
及其药学上可接受的盐类。
式 I 化合物可抑制生长因子受体(如 HER1、HER2 和 HER4)的
酪氨酸激酶活性,因此可用作抗增殖剂。式 I 化合物还可用于治疗与通过生长因子受体运行的
信号转导通路相关的其他疾病。
