Vascular endothelial growth factor-2 (VEGFR-2) plays a pivotal role in tumor angiogenesis. Herein, a library of novel 2-(4-(1H-indazol-6-yl)-1H-pyrazol -1-yl)acetamide derivatives were designed and synthesized as VEGFR-2 inhibitors based on scaffold hopping strategy. These compounds exhibited the excellent inhibitory in both VEGFR-2 and tumor cells proliferation. Especially, compound W13 possessed
血管内皮生长因子2(V
EGFR-2)在肿瘤血管生成中起关键作用。在此,基于支架跳跃策略,设计并合成了新颖的2-(4-(1 H-

生物作为V
EGFR-2
抑制剂。这些化合物对V
EGFR-2和肿瘤细胞的增殖均表现出优异的抑制作用。尤其是,化合物W13具有有效的V
EGFR-2抑制作用(IC 50 = 1.6 nM)和针对
HGC-27肿瘤细胞的抗增殖作用(IC 50 = 0.36±0.11μM),以及对正常GES-1细胞的毒性较小(IC 50 = 50)。 187.46±10.13微米 此外,W13通过调节MMP-9和E-cadherin的表达明显抑制了
HGC-27细胞的集落形成,迁移和侵袭,并通过增加ROS的产生和调节细胞凋亡蛋白的表达来诱导
HGC-27细胞凋亡。此外,W13阻断了
HGC-27细胞中的
PI3K-Akt-mTOR信号传导途径。另外,通
