Moreover, the enzymatic assessment of five derivatives (2,4b, 6, 8, 9a) against VEGFR-2 tyrosine kinase showed significant inhibitory activities with IC50 of 11.5, 8.2, 10.3, 10.5 and 9.4 nM respectively. Further studies revealed the ability of compound 9a to have a strong DNA-binding affinity of 36.06 μM via DNA/methyl green assay. Moreover, molecular docking study was carried out to reveal the binding
开发了一种在微波 (MW) 活化下合成 1,3,4-噻二唑基化合物的绿色高效方法。亲核试剂 N-(5-amino-1,3,4-thiadiazol-2-yl)thiophene-2-carboxamide ( 3 ) 被合成并与不同的碳亲电试剂反应得到噻二唑并嘧啶或咪唑并噻二唑啉衍生物(4 – 6和8),分别。此外,3与对氯苯甲醛和不同碳亲电试剂/或亲核试剂在微波辐射下的一锅反应生成环状噻二唑并嘧啶衍生物10 – 15. 此外,芳香胺和/或某些杂环化合物的钾盐与氯乙酰氨基-噻二唑6 的亲核取代产生衍生物16 – 20。所有的新衍生物都是通过常规和 MW 辐照方法合成的。所有新的 1,3,4-噻二唑衍生物均针对四种癌细胞系 HepG-2、MCF-7、HCT-116 和 PC-3 进行了评估。大多数合成化合物的抗增殖活性对癌细胞系表现出优异的广谱细胞毒活性,IC 50值范围为 3.97 至 9
