A series of 3-acetylcoumarin-based thiosemicarbazones and their copper(II) complexes were synthesized and characterized by elemental analysis, IR, UV–Vis, HR-ESI Mass, NMR, EPR and single crystal XRD. The XRD study revealed thione tautomer for TSCs 3 (AcCmDEtTSC) and 4 (AcCmDPrTSC) whereas Cu(II) complex 8 [Cu(AcCmDPrTSC)Cl] has distorted square planar geometry around the metal ion. Compound 1 (AcCmMeHTSC)
合成了一系列基于 3-乙酰香豆素的缩氨基硫脲及其铜 (II) 配合物,并通过元素分析、IR、UV-Vis、HR-ESI Mass、NMR、EPR 和单晶 XRD 进行了表征。 XRD 研究揭示了 TSC 3 ( AcCmDEtTSC)和4 ( AcCmDPrTSC)的硫酮互变异构体,而 Cu(II) 络合物8 [Cu(AcCmDPrTSC)Cl]在金属离子周围具有扭曲的方形平面几何形状。缩氨基硫脲 (TSC) 中的化合物1 ( AcCmMeHTSC)对两种乳腺癌细胞系均更有效:MCF-7 (IC 50 ; 13.02 µg/mL) 和 MDA-MB-231 (IC 50; 42.71 µg/mL),而Cu(II) 配合物中的化合物7 [Cu(AcCmDEtTSC)Cl] (IC 50; 32.84 µg/mL) 和8 [Cu(AcCmDPrTSC)Cl] (IC 50: 34.69 µg/mL)
