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, PDGFR, HER-1, HER-2, 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) 化合物及其药学上可接受的盐类。式 (I) 化合物可抑制生长因子受体(如 V
EGFR-2、FGFR-1、PDGFR、HER-1、HER-2)的
酪氨酸激酶活性,因此可用作抗癌剂。式(I)化合物还可用于治疗与通过生长因子受体运行的
信号转导通路有关的其他疾病。
