series of novel geminal bis 1,2,3-triazoles linked to 2H-furo[2,3-d][1,3]thiazine-2,4,5(1H,6H)-trione (3a-3m) were prepared in one pot starting from 5-Acetyl-4-Hydroxy-1,3-thiazine-2,6-dione (1) to 6,6-diazido-2H-furo[2,3-d][1,3]thiazine-2,4,5(1H,6H)-trione (2) followed by Cu(I)-catalyzed azide-alkyne cycloaddition. The synthesized compounds were further explored for in vitro cytotoxic activity against
在这项研究中,一系列与 2 H -呋喃 [2,3- d ][1,3] 噻嗪-2,4,5(1H,6H)-三酮相连的新型孪生双 1,2,3-三唑(3a-3m ) 从 5-Acetyl-4-Hydroxy-1,3-thiazine-2,6-dione ( 1 ) 到 6,6-diazido-2 H -furo [2,3- d ][1,3]thiazine-2,4,5(1H,6H)-trione ( 2 ) 然后是 Cu(I) 催化的叠氮化物-炔烃环加成反应。进一步研究了合成的化合物对 PC3、A549、MCF-7 和 HeLa 细胞系的体外细胞毒活性,结果显示五种化合物3c、3d、3g、3l和3m 已显示出与标准药物依托泊苷相当的体外细胞毒活性。
