antiproliferative activity, suggesting the Zn(II) complex did not act as a chaperone to deliver the ligand intracellularly, in contrast to similar bis(thiosemicarbazone) cobalt(III) complexes [King et al. Inorg. Chem.2017, 56, 6609–6623]. However, five of the eight bis(thiosemicarbazone) Cu(II) complexes maintained or increased their antiproliferative activity, relative to the ligand alone, and a mechanism of Cu-induced
一系列8个双(硫代半碳鎓)配体以及它们各自的铜(II)和锌(II)配合物中的16个在配体主链的二亚胺位置上含有氢,甲基,吡啶基,苯基和/或乙基取代基的组合,合成和表征。这项研究的目的是确定在骨架的二亚胺位置和末端N原子上具有不同取代基的一系列类似物中的结构-活性关系。Cu(II)配合物Cu(GTSM 2),Cu(GTSCM),Cu(PyTSM 2),Cu(EMTSM 2)和Cu(PGTSM 2)表现出扭曲的正方形平面几何形状,而Zn(II)配合物Zn(II ATSM 2)(DMSO),Zn(PyTSM 2)(DMSO)和Zn(PGTSM 2)(H 2 O)形成扭曲的方形锥体形状。循环伏安法表明,铜(II)配合物显示准可逆的电化学。在这些试剂中,Cu(II)乙二醛双(4,4-二甲基-3-硫代半碳酮)[Cu(GTSM 2)]和Cu(II)二乙酰基双(4,4-二甲基-3-硫代半碳酮)[Cu(ATSM
