2-acetyl pyridine and containing an azepane ring (hexamethyleneiminyl ring) incorporated at N(4)-position, HL1 (1) and HL2 (2) with platinum(II) afforded the complexes, [Pt(L1)Cl] (3) and [Pt(L2)Cl] (4). Characterization of the compounds was accomplished by means of elemental analysis and spectroscopic techniques NMR, UV–vis and IR spectroscopy. The single-crystal X-ray structure of complex [Pt(L2)Cl] (4)
2-甲酰基和2-乙酰基吡啶并在N(4)-位处并入HL 1(1)和HL 2(2)的氮杂环戊烷环(六亚甲基亚甲基环)与铂(II)的硫半脲反应,得到配合物, [Pt(L 1)Cl](3)和[Pt(L 2)Cl](4)。化合物的表征通过元素分析和光谱技术NMR,UV-vis和IR光谱法完成。配合物[Pt(L 2)Cl](4)的单晶X射线结构表明,配体单阴离子在与金属过孔的平面构型中进行配位吡啶基N原子,亚胺基N原子和硫醇基S原子。化合物1 - 4已经评估了抗增殖活性体外抗三种人癌细胞系:MCF-7(人乳腺癌细胞系),T24(膀胱癌细胞系),A-549(非小细胞肺癌)和小鼠L-929(从菌株L克隆的成纤维细胞样细胞系)。配体2表现出对所有四种癌细胞系的抗癌活性,而配体1表现出对MCF-7和L-929细胞系的选择性,而复合物4表现出对A-549和T-24癌细胞系的抗性。另外,还对携带白血病P388的小
