Three series of novel indazole–pyrimidine based compounds were designed, synthesized and biologically evaluated as VEGFR-2 kinase inhibitors. The most active compound 6i (IC50 = 24.5 nM) was further evaluated against a HUVEC cell line showing an IC50 of 1.37 μM. Moreover, it showed an indirect anti-angiogenic effect through the suppression of secretion of VEGF and TGF-b1 from prostate cancer cells
设计,合成了三种基于吲哚-嘧啶的新型化合物,并将其作为VEGFR-2激酶抑制剂进行了生物学评估。针对显示IC 50为1.37μM的HUVEC细胞系,进一步评估了活性最高的化合物6i(IC 50 = 24.5 nM)。此外,它通过抑制前列腺癌细胞中VEGF和TGF-b1的分泌显示出间接的抗血管生成作用。NCI选择了五种化合物以评估其对10μM细胞系完整NCI面板的体外抗癌活性。进一步选择化合物6e和6f进行5剂量测试。化合物6e表现出纳摩尔GI 50对几种细胞系的值:CCRF-CEM(901 nM),MOLT-4(525 nM)和CAKI-1(992 nM),对其余细胞系的数微摩尔活性为1.05μM至2.41μM。化合物6f对整个细胞系范围从1.55μM到7.4μM表现出一位微摩尔活性。使用Autodock软件,进行了分子对接研究以研究目标化合物与VEGFR-2的预测结合模式。此外,对化合物
