lowest GI50 value, 3-(2-hydroxy-4,5-dimethoxyphenyl)-5-(naphthalen-1-yl)-N-(3,4,5-trimethoxyphenyl)-pyrazolinyl-1-carbothioamide, was subjected to further biological studies, including cell viability and apoptosis assays to examine levels of annexin-V in the outer plasma membrane layer and poly ADP-ribose polymerase cleavage. Additionally, in vitro kinase assays were performed, and Abelson murine leukemia
为了寻找具有抗癌活性的化合物,设计并合成了37种2-吡唑啉基-1-碳硫酰胺衍生物。克隆形成细胞存活测定法适于测量合成衍生物对HCT116人结肠癌细胞系的细胞毒性。半数最大细胞生长抑制浓度(GI 50)为0.49至41.22 µM。GI 50值最低的化合物3-(2-羟基-4,5-二甲氧基苯基)-5-(萘-1-基)-N-(3,4,5-三甲氧基苯基)-吡唑啉基-1-碳硫酰胺进行了进一步的生物学研究,包括细胞生存力和细胞凋亡分析,以检查质膜外层膜联蛋白V的水平和聚ADP-核糖聚合酶的裂解。此外,在体外进行了激酶测定,并且Abelson鼠白血病病毒病毒癌基因同源物1(Abl 1)酪氨酸激酶表现出良好的抑制活性。使用计算机对接阐明了目标化合物与Abl 1之间的结合方式。基于2-吡唑啉基-1-碳硫代酰胺的定量结构-活性关系而衍生的药效基团将帮助我们设计新颖的化学治疗剂。
