There is provided medicaments, particularly a vascular endothelial growth factor (VEGF) inhibitor which is useful as a therapeutic drug for solid tumors, diabetic retinopathy and the like diseases in which angiogenesis is taking a role. That is, since a novel 3-quinolin-2(1H)-ylideneindolin-2-one derivative or a salt thereof has good VEGF inhibitory action, angiogenesis inhibitory action and anti-tumor action, it is useful as ideal VEGF inhibitor, angiogenesis inhibitor and anti-tumor agent.
提供药物,特别是一种血管内皮生长因子(V
EGF)
抑制剂,可用作固体肿瘤、糖尿病视网膜病变等疾病的治疗药物,在这些疾病中血管生成扮演着重要角色。也就是说,由于一种新型的3-
喹啉-2(1H)-基
亚胺吲哚-2-
酮衍
生物或其盐具有良好的V
EGF抑制作用、血管生成抑制作用和抗肿瘤作用,因此它作为理想的V
EGF
抑制剂、血管生成
抑制剂和抗肿瘤剂是非常有用的。
