picolinamide derivatives bearing (thio)urea and dithiocarbamate moieties were designed and synthesized as VEGFR-2 kinase inhibitors. All the new compounds were screened for their cytotoxic activity against A549 cancer cell line and VEGFR-2 inhibitory activity. Compounds 7h, 9a and 9l showed potent inhibitory activity against VEGFR-2 kinase with IC50 values of 87, 27 and 94 nM, respectively in comparison
设计并合成了两个带有(硫)脲和二硫代氨基甲酸酯部分的吡啶甲酸酰胺衍生物作为VEGFR-2激酶抑制剂。筛选所有新化合物对A549癌细胞系的细胞毒活性和VEGFR-2抑制活性。与 作为参考的索拉非尼(IC 50 = 180 nM)相比,化合物7h,9a和9l显示出对VEGFR-2激酶的有效抑制活性,IC 50值分别为87、27和94 nM 。化合物7h,9a和9l进一步筛选了它们对来自不同来源(Panc-1,OVCAR-3,HT29和786-O细胞系)的特异性抗性人类癌细胞系的抗肿瘤活性,其中化合物7h在大多数细胞系中均显示出明显的细胞死亡。对最有效的VEGFR-2抑制剂进行了多激酶抑制测定,其中化合物7h对EGFR,HER-2,c-MET和MER激酶的效价增强。如膜联蛋白V-FITC染色所示,用9a处理的A549细胞的细胞周期分析显示,细胞周期停在G2 / M期,并具有促凋亡活性。
