e were further evaluated for their VEGFR‐2 inhibition. Compounds 4c and 4b potently inhibited VEGFR‐2 at IC50 values of 0.12 ± 0.01 and 0.13 ± 0.02 µM, respectively, which are nearly equipotent to the sorafenib IC50 value (0.10 ± 0.02 µM). Furthermore, molecular docking studies were performed for all synthesized compounds to assess their binding pattern and affinity toward the VEGFR‐2 active site.
设计、合成了一系列新的苯并恶唑/苯并噻唑衍生物 4a-c-11a-e,并评估其对 HepG2、HCT-116 和 MCF-7 细胞的抗癌活性。HCT-116 是对新衍生物影响最敏感的细胞系。特别是,发现化合物 4c 是对 HepG2、HCT-116 和 MCF-7 细胞最有效的衍生物,其 IC50 值分别为 = 9.45 ± 0.8、5.76 ± 0.4 和 7.36 ± 0.5 µM。化合物4b、9f和9c对HepG2细胞显示出最高的抗癌活性,IC50值分别为9.97±0.8、9.99±0.8和11.02±1.0μM,对HCT-116细胞的IC50值为6.99±0.4±0.4±0.7。和 8.15 ± 0.8 µM,MCF-7 细胞的 IC50 值分别为 7.89 ± 0.7、8.24 ± 0.7 和 9.32 ± 0.7 µM,与作为参考药物的索拉非尼相比,IC50 值为 9。分别为 18
