reference drug, sorafenib (IC50 = 0.588 ± 0.06 µM). Furthermore, docking study was performed in order to understand the binding pattern of the new compounds into VEGFR-2 active site. Docking results attributed the potent VEGFR-2 inhibitory effect of the new compounds as they bound to the key amino acids in the active site, Glu883 and Asp1044, as well as their hydrophobic interaction with the receptor
为了提高所设计化合物对受体活性位点的结合亲和力,通过对VEGFR-2报道的抑制剂7的修饰,设计并合成了十六种基于喹唑啉的新型衍生物。评价设计的化合物的VEGFR-2抑制作用。已经建立了抑制VEGFR-2作为治疗癌症的治疗策略。新化合物对HepG-2,MCF-7和HCT-116细胞系具有生物活性。阿霉素和索拉非尼用作阳性对照。 与参考药物阿霉素(IC 50)相比,观察到化合物18 d具有有希望的细胞毒活性(IC 50 = 3.74±0.14、5.00±0.20和6.77±0.27 µM)。 = 8.28、9.63和7.67 µM)和索拉非尼(IC 50 = 7.31、9.40和7.21 µM)。测试了活性最高的化合物的体外VEGFR-2抑制活性。VEGFR-2抑制的结果与细胞毒性数据一致。因此,化合物18 d的VEGFR-2抑制活性(IC 50 = 0.340±0.04 µM)优于参考药物索拉非尼(IC
