A series of hybrid aza heterocycles containing pyrazolo[3,4-d]pyrimidin-4(5H)-ones tethered to 1,2,3-triazole scaffold were synthesized from 1,3-dipolar cycloaddition reaction of pyrazolopyrimidinone based alkyne with azides using Cu(II) catalyst in presence of sodium ascorbate and evaluated for their anticancer efficacy in vitro against C6 rat and U87 human glioma cell lines. These compounds induced
由吡唑并吡咯烷二酮基炔与叠氮化物的1,3-偶极环加成反应合成了一系列含吡唑并[3,4-d]嘧啶-4(5 H)-与1,2,3-三唑骨架连接的杂氮杂杂环。在抗坏血酸钠存在下使用Cu(II)催化剂,并评估了它们在体外对C6大鼠和U87人神经胶质瘤细胞系的抗癌效果。这些化合物诱导了C6大鼠和U87人神经胶质瘤细胞增殖的浓度依赖性抑制。化合物5F被捕细胞在小号-PHASE在U87 GBM细胞系的细胞周期并诱导其凋亡的。此外,Caspase-3,PARP的裂解和p53的上调证明了细胞凋亡。在计算机上对接研究表明,化合物5a,5f和5l与TGFBR2的结合比其他化合物更有效。
