synthesized conjugates 12a-aa, compound 12k was found to exhibit significant IC50 values 5.85, 7.87, 6.41 and 10.43 μM against MDA-MB-231 (breast), HepG2 (liver), A549 (lung) and PC-3 (prostate) cancer cell lines, respectively. All these compounds were further evaluated for their inhibitory activities against VEGFR-2 protein. The results specified that among the tested compounds, 12d, 12e, 12k, 12l, 12p
通过分子杂交从已知结构基序开发新的小分子是药物发现的趋势之一。在这方面,我们通过分子杂交策略将两个药效基团(嘧啶和硫代吲哚)结合在一个实体中,并在嘧啶的C2位置引入尿素官能团以提高H键相互作用的效率。在合成的缀合物12a-aa中,发现化合物12k对MDA-MB-231(乳腺癌),HepG2(肝),A549(肺)和PC-3(前列腺)的IC50值分别为5.85、7.87、6.41和10.43μM。 )癌细胞系。进一步评估所有这些化合物对VEGFR-2蛋白的抑制活性。结果表明,在测试化合物中,12d,12e,12k,12l,12p,12q,12t和12u显着抑制了VEGFR-2,IC50值为310-920 nM,与阳性对照(210 nM)相关。HUVECs中的管形成分析显着抑制了血管生成,transwell分析则显着抑制了细胞侵袭。通过线粒体膜电位去极化,ROS产生增加和随后的DNA损伤导致凋亡
