the anticancer treatment, a new class of chalcone-pyrrolo[2,1-c] [1,4]benzodiazepine (PBD) conjugates linked through a 1,2,3-triazole moiety containing alkane spacers has been designed and synthesized. Combining these two core pharmacophore structures with modifications at A-C8/C-C2-position of PBD ring system yielded analogs with improved efficacy and have shown promising in vitro anticancer activity
为了开发用于抗癌治疗的多靶点药物,一类新的查尔酮-吡咯并[2,1- c ] [1,4]苯并二氮杂(PBD)缀合物通过包含烷撑间隔基的1,2,3-三唑部分连接设计和合成。将这两个核心药效团结构与A -C8 / C处的修饰相结合PBD环系统的-C2位置可产生具有改进功效的类似物,并显示出有希望的体外抗癌活性,范围在<0.1–2.92μM之间。这些PBD偶联物导致G1细胞周期停滞,并对G1细胞周期调节蛋白(如细胞周期蛋白D1和Cdk4)产生影响。这些缀合物还显示出对在乳腺癌细胞增殖中起重要作用的NF-kB,Bcl-XL蛋白的抑制作用。这些发现表明,该系列化合物中的一种4d最有效,并且有可能进行详细研究。
