thiosemicarbazones Ga(III) complexes, which are 2:1 and 1:1 ligand/Ga(III) complexes, were synthesized and determined by X-ray single crystal diffraction. The antiproliferative activity of these Ga(III) complexes have been examined to illuminate the structure-activity relationships essential to form Ga(III) complexes with remarkable anticancer activity. In addition, Ga(III) complexes where the metal/ligand ratio was
合成了两种类型的2:1和1:1配体/ Ga(III)的2-吡啶甲醛硫代半碳氮烷Ga(III)配合物,并通过X射线单晶衍射测定。这些Ga(III)配合物的抗增殖活性已得到检验,以阐明形成具有显着抗癌活性的Ga(III)配合物必不可少的结构-活性关系。此外,金属/配体比例为1:1(C4)的Ga(III)配合物的抗增殖活性明显高于1:2(C3)。与不含金属的配体相比,Ga(III)络合物在NCI-H460细胞中引起caspase-3和9活性的显着增加。与选定的药剂一起孵育后,Cyt C从线粒体中释放出来,从而在某种程度上介导了半胱天冬酶的激活。
