The present invention provides compounds of formula I
and pharmaceutically acceptable salts thereof. The compounds of the invention inhibit tyrosine kinase activity of growth factor receptors such as HER1, HER2 and HER4 thereby making them useful as antiproliferative agents. The 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的化合物及其药用盐。本发明的化合物抑制
酪氨酸激酶活性,如HER1、HER2和HER4等生长因子受体,因此使它们可用作抗增殖剂。这些化合物还可用于治疗与通过生长因子受体进行
信号转导途径相关的其他疾病。
