of the parent compound malten. The acid-base behavior and the binding properties towards transition, alkaline-earth (AE) and rare-earth (RE) cations in aqueous solution, studied by potentiometric, UV-Vis and NMR analysis, are reported along with biological studies on DNA and leukemia cells. Both ligands form stable complexes with Cu(II), Zn(II) and Co(II) that were studied as metallo-receptors for AE
两个基于麦芽酚的配体,N,N'-bis((3-hydroxy-4-pyron-2-yl)methyl)-1,4-piperazine (L1) 和 N,N',N'-tris((3 -羟基-4-吡喃-2-基)甲基)-N-甲基乙二胺(L2)被合成并表征。L1 和 L2 分别包含由二胺片段隔开的两个和三个麦芽酚单元,旨在评估母体化合物麦芽糖的结构修饰如何影响生物学和结合特征。酸碱行为和对水溶液中过渡、碱土 (AE) 和稀土 (RE) 阳离子的结合特性,通过电位、UV-Vis 和 NMR 分析进行研究,以及对 DNA 和白血病细胞。两种配体与 Cu(II)、Zn(II) 和 Co(II) 形成稳定的复合物,这些复合物被研究为中性 pH 下 AE 和 RE 的金属受体。L1 复合物比 L2 复合物受硬阳离子的影响更大,L1-Cu(II) 系统深受 RE 的影响。结构修饰改变了作用机制:L1 部分保持了诱导
