In this work, a new series of imidazo[2,1-b]thiazole was designed and synthesized. The new compounds are having 3-fluorophenyl at position 6 of imidazo[2,1-b]thiazole and pyrimidine ring at position 5. The pyrimidine ring containing either amide or sulphonamide moiety attached to a linker (ethyl or propyl) at position 2 of the pyrimidine ring. The final compounds were selected by NCI for in vitro cytotoxicity
在这项工作中,设计并合成了一系列新的咪唑并[2,1-b]噻唑。新化合物在咪唑并[2,1-b]噻唑的6位具有3-氟苯基,在5位具有嘧啶环。嘧啶环含有酰胺或磺酰胺部分,该酰胺或磺酰胺部分连接至酰胺的2位连接基(乙基或丙基)嘧啶环。通过NCI选择最终化合物进行体外细胞毒性筛选。大多数衍生物显示出对结肠癌和黑色素瘤细胞系的细胞毒活性。另外,使用索拉非尼作为阳性对照,在A375和SK-MEL-28细胞系中测定了目标化合物的IC50。与索拉非尼相比,化合物12b,12c,12e,12f,15a,15d,15f,14g和15h表现出优异的活性。测试了最有效的化合物抗野生型BRAF,v600e BRAF和CRAF。
