showed a high activity against VEGFR-2 with an IC50 value of 2.5 ± 0.04 µM, almost equal to that of sorafenib (IC50 = 2.4 ± 0.05 µM). Further studies revealed the ability of this promising quinazoline derivative 31 to induce apoptosis and arrest cell cycle growth at G2/M phase. In vivo antitumor activities of the synthesized compounds revealed that compounds 30 and 31 possessed significant tumor growth inhibition
已经建立了抑制VEGFR-2作为治疗癌症的治疗策略。因此,设计并合成了具有VEGFR-2抑制剂的结构特征的新的基于喹唑啉的衍生物。使用MTT分析方法评估了针对三种人类癌细胞系(HepG-2,MCF-7和HCT-116)的抗增殖活性。阿霉素和索拉非尼用作阳性对照。化合物26b,29a,29b和30对所有细胞系均表现出优异的抗癌活性。此外,化合物31的活性最高,IC 50值分别为3.97±0.2、4.83±0.2和4.58±0.3 µM。进一步评估了最具活性的细胞毒剂的VEGFR-2抑制活性,化合物31对VEGFR-2表现出高活性,IC50值为2.5±0.04 µM,几乎等于索拉非尼(IC50 = 2.4±0.05 µM)。进一步的研究揭示了这种有前途的喹唑啉衍生物31诱导细胞凋亡并阻止G2 / M期细胞周期生长的能力。合成化合物的体内抗肿瘤活性表明化合物30和31具有显着的肿瘤生长抑制作用。
