In this paper, based on Plastoquinone (PQ) analogs possessing substituted aniline containing alkoxy group(s), new 2,3-dimethyl-5-amino-1,4-benzoquinones (PQ1-15) were designed and synthesized in either two steps or one-pot reaction. Specifically, the substituted amino moiety containing mono or poly alkoxy group(s) with various positions and groups were mainly explored to understand the structure-activity
本文基于具有取代苯胺含烷氧基的Plastoquinone(PQ)类似物,设计并合成了新的2,3-二甲基-5-氨基-1,4-苯醌(PQ1-15),分两步进行或一锅反应。具体而言,主要探索包含具有不同位置和基团的单或多烷氧基的取代氨基部分,以了解针对三种人类癌细胞系(K562,Jurkat和MT-2)的细胞毒活性的构效关系。和人类外周血单核细胞(PBMC)。发现PQ2是对K562和Jurkat细胞系具有IC 50的最有效的抗癌化合物值分别为6.40±1.73μM和7.72±1.49μM。有趣的是,该化合物对正常的PBMC和MT-2癌细胞均无细胞毒性。选择在MTT分析中显示出显着选择性的PQ2进行凋亡/坏死评估,结果显示其在处理6小时后诱导了K562细胞系的凋亡。PQ2在八个激酶组中显示出与伊马替尼不同的抑制谱,抗阿贝尔森激酶1(Abl1)活性。在计算机上预测了PQ2进入Abl ATP结合口袋的
