(CT-DNA) and BSA, with a higher affinity to BSA. Palladium(II) complex exhibited 5-fold a stronger affinity to DNA binding in comparison to zinc(II), but no significantly higher than gold(III) complex. Furthermore, palladium(II) and gold(III) complexes demonstrated a similar affinity toward BSA and these interactions are stronger than showed by zinc(II) complex.
摘要 二硫代氨基甲酸酯具有高亲脂性和良好的螯合特性,可以提供稳定的过渡金属络合物,并使这些金属基药物能够达到其生物靶点。钯 (II) 和金 (III) 配合物由于其与铂 (II) 化合物的结构相似性,可以成为实施和开发新药理剂的竞争候选者。在此,合成了以 N-羧基亚氨基二乙酸三铵为配体的新型金 (III) 配合物,并通过元素分析、摩尔电导率测量、FT-IR 以及 1H 和 13C NMR 光谱对其进行了表征。通过密度泛函理论 (B3LYP/def2tzvp) 检查并与模拟钯 (II) 和锌 (II) 配合物比较所提出的结构。此外,对金 (III)、钯 (II) 和二硫代氨基甲酸锌 (II) 复合物进行了紫外/可见光光谱仪的 DNA 结合研究以及荧光分光计的溴化乙锭 (EB) 和牛血清白蛋白 (BSA) 淬灭研究。研究的复合物对小牛胸腺 DNA (CT-DNA) 和 BSA 显示出良好的亲和力,对
Syntheses, structures and antifungal activities of novel Co, Mo and Pt complexes with triammonium N,N-diacetatedithiocarbamate
Co(II) centres was observed. The structure of the Co(III) complex (3) reveals a neutral mononuclear complex with a hexacoordinated Co(III) centre, with the molecular formula [Co(H2dadtc)3]. Co(III) lies at the twofold rotation axis, and is in the centre of a distorted octahedron formed by six sulfur atoms from three CSS groups. In the [MoVI(dadtc)4]6− anion of the complex 4, the Mo(VI) lies on the fourfold
