The present invention provides compounds of formula (I), (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.
本发明提供式(I)的化合物,式(I)的药物可接受的盐。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,因此使它们可用作抗癌剂。式(I)化合物也适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。
