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, 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.
本发明提供了公式I的化合物
1
以及药用可接受的盐。
公式I化合物抑制生长因子受体如V
EGFR-2、FGFR-1的
酪氨酸激酶活性,从而使其作为抗癌剂具有用途。公式I化合物还用于治疗其他通过生长因子受体作用的
信号转导通路相关的疾病。
