The present invention relates to a compound represented by the formula (I’) wherein A is a benzene ring optionally having substituents, R1, R2a and R3 are each a hydrogen atom, a hydrocarbon group optionally having substituents or a heterocyclic group optionally having substituents, R1 and R2a may form a ring via X, when R1 and R2a form a ring via X, R1 and R2a are each a bond or a divalent C1-5 acyclic hydrocarbon group optionally having substituents, and X is a bond, an oxygen atom, an optionally oxidized sulfur atom or an imino group optionally having a substituent, provided that R1, R2a and X are not bonds at the same time, or a salt thereof, and an agent for inhibiting kinase (phosphorylation enzyme), which contains this compound or a prodrug thereof. The compound of the present invention has an inhibitory activity against kinase such as a vascular endothelial growth factor receptor (VEGFR) and the like, and is useful as an agent for the prophylaxis or threatment of cancer and the like.
本发明涉及一种由式(I')表示的化合物,其中A是一个苯环,可选地具有取代基,R1、R2a和R3分别是氢原子,可选地具有取代基的碳氢基团或可选地具有取代基的杂环基团,R1和R2a可以通过X形成环,当R1和R2a通过X形成环时,R1和R2a分别是键或可选地具有取代基的二价C1-5非环烃基团,X是键,氧原子,可选地氧化的硫原子或可选地具有取代基的亚胺基团,前提是R1、R2a和X不同时为键,或其盐,以及含有该化合物或其前药的抑制激酶(磷酸化酶)的药剂。本发明的化合物对激酶如血管内皮生长因子受体(VEGFR)等具有抑制活性,并可用作预防或治疗癌症等疾病的药剂。
