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, 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化合物及其药学上可接受的盐。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,因此可用作抗癌剂。公式I化合物还可用于治疗通过生长因子受体操作的
信号转导途径引起的其他疾病。
