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的化合物及其药用可接受的盐。式I的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,因此使它们可用作抗癌剂。式I的化合物还可用于治疗通过生长因子受体信号传导途径操作的其他疾病。
