Anticancer potential of new 3-nitroaryl-6-(N-methyl)piperazin-1,2,4-triazolo[3,4-a]phthalazines targeting voltage-gated K+ channel: Copper-catalyzed one-pot synthesis from 4-chloro-1-phthalazinyl-arylhydrazones

copper-catalytic procedure consists of two simultaneous reactions: (i) a direct intramolecular dehydrogentaive cyclization between ylidenic carbon and adjacent pyrazine nitrogen to form 1,2,4-triazolo ring and, (ii) a direct N-amination on carbon-chlorine bond. Then, an in vitro anticancer evaluation was performed for the synthesized compounds against five selected human cancer cells (A549, MCF-7, SKBr3, PC-3 and
通过简便有效的一锅铜催化程序,从4-氯代-3-氯苯甲酸制备了一系列六个3-芳基-6-(N-甲基哌嗪)-1,2,4-三唑并[3,4- a ]酞嗪。 1-酞嗪基-芳基hydr具有相对较好的产率(62–83%)。一锅法铜催化程序包括两个同时发生的反应:(i)分子内碳与相邻的吡嗪氮之间的直接分子内脱氢热化环化反应,形成1,2,4-三唑环,(ii)在反应中进行直接N胺化碳-氯键。然后,在体外对合成的化合物针对五种选定的人类癌细胞(A549,MCF-7,SKBr3,PC-3和HeLa)进行了抗癌评估。硝基衍生物对癌症菌株的活性比对其余测试化合物的活性高得多。具体而言,化合物8d被确定为最有前途的抗癌药,对人真皮成纤维细胞具有显着的生物学反应且相对毒性较低。化合物8d对PC3,MCF-7和SKBr3癌细胞的细胞毒性作用更为显着,其低微摩尔IC 50值为0.11至0.59μM,优于阿霉素药物。机理实验和理论研究表明,化合物8d可作为K
