The present invention provides compounds of formula (I), and pharmaceutically acceptable salts thereof. The formula (I) compounds inhibit the tyrosine kinase activity of growth factor receptors such as VEGFR-2 and FGFR-1, thereby making them useful as anti-cancer 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。式(I)化合物抑制生长因子受体的
酪氨酸激酶活性,如V
EGFR-2和FGFR-1,因此使它们有用作抗癌剂。式(I)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。
