The 3-methoxy-2-methyl-4H-pyran-4-one (MeO-Malt) was incorporated into the structure of 1H-1,2,3-triazole-4-carboxylate via click chemistry. The new ligand methyl-1-((3-methoxy-4-oxo-4H-pyran-2-yl)methyl)-1H-1,2,3-triazole-4-carboxylate (3) was reacted with platinum to give mononuclear complex 4. Investigation of the crystal structure of the free ligand 3 highlighted a chain structure established by
通过点击化学将 3-甲氧基-2-甲基-4 H-吡喃-4-酮 (MeO-麦芽) 结合到 1 H -1,2,3-三唑-4-羧酸酯的结构中。新配体甲基-1-((3-methoxy-4-oxo-4H-pyran-2-yl)methyl)-1 H -1,2,3-triazole-4-carboxylate ( 3 ) 与铂反应得到给出单核复合物4 . 对游离配体3的晶体结构的研究突出了通过三唑单元和羧基之间的氢键建立的链结构。通过 ATR-IR、NMR 和 UV-vis 光谱对铂配合物进行了表征。3和4 的循环伏安图也进行了讨论。此外,还测试了它们对鳞状细胞癌 (A431)、肺癌 (A549)、人类黑色素瘤 (A375 和 HT144) 和人类结肠直肠癌 (HT29 和 HCT116) 细胞的细胞毒活性。
