The present invention provides a fused heterocyclic compound having a tyrosine kinase inhibitory action, which is represented by the formula:
wherein
R1 is a hydrogen atom, a halogen atom, or an optionally substituted group bonded via a carbon atom, a nitrogen atom or an oxygen atom;
R2 is a hydrogen atom, or an optionally substituted group bonded via a carbon atom or a sulfur atom, or
R1 and R2, or R2 and R3 are optionally bonded to each other to form an optionally substituted ring structure;
R3 is a hydrogen atom or an optionally substituted aliphatic hydrocarbon group, or
R3 is optionally bonded to the carbon atom on ring A to form an optionally substituted ring structure;
ring A is an optionally substituted benzene ring; and ring B is
(i) an optionally substituted fused ring, or
(ii) a pyridine ring having optionally substituted carbamoyl (the pyridine ring is optionally further substituted).
本发明提供了一种具有酪氨酸激酶抑制作用的融合杂环化合物,其化学式如下:
其中
R1是氢原子、卤素原子或通过碳原子、氮原子或氧原子键合的可选择取代基;
R2是氢原子,或通过碳原子或硫原子键合的可选择取代基,或
R1和R2,或R2和R3可选择键合在一起形成可选择取代的环结构;
R3是氢原子或可选择取代的脂肪烃基,或
R3可选择键合到环A上的碳原子上形成可选择取代的环结构;
环A是可选择取代的苯环;环B是
(i) 可选择取代的融合环,或
(ii) 具有可选择取代的氨基甲酰基的吡啶环(吡啶环可进一步取代)。
