The present invention provides compounds of formula I,
1
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.
本发明提供公式I的化合物及其药学上可接受的盐。公式I的化合物抑制生长因子受体的
酪氨酸激酶活性,例如V
EGFR-2和FGFR-1,因此使它们成为抗癌剂。公式I的化合物还可用于治疗与
信号转导途径相关的其他疾病,这些途径通过生长因子受体运作。
