    Synthesis, Characterization, and Electrochemical Studies of Ternary Complexes of Lanthanum(III) and Cerium(III) with Some Naphthylideneamino Acids and Imidazoles
    摘要:
    A new series of ternary lanthanium(III) and cerium(III) complexes containing Schiff bases derived from some amino acids, viz: glycine; alanine; phenylalanine; valine and leucine with 2-hydroxy-1-naphthaldehyde as primary ligands, and 1-methylimidazole & 1,2-dimethylimidazole as secondary ligands were synthesized. The complexes were characterized on the bases of microanalyses, electrical conductance, IR & H-1 NMR spectra, thermal analysis and cyclic voltammetric data. All complexes were found to be non-electrolytes with the general formula of [ML(NO3 )Im center dot nH(2)O] (where M = La(III) or Ce(III), L = naphthylideneamino acids, Im = 1-methylimidazole or 1,2-dimethylimidazole and n = 1 or 2). The redox properties of some of the ternary complexes of La(III) and Ce(III) were examined using cyclic voltammetry in 0.1 mol dm(-3) TBAP/DMSO solutions. The reduction potentials of the investigated complexes showed a dependence upon the nature of the amino acid of the ligand. The stability of the complexes is discussed on the basis of the thermal and electrochemical data.

    摘要:
    髓鞘形成是脊椎动物神经系统中最基本的生物过程之一。中枢神经系统 (CNS) 髓鞘形成异常和变化可见于许多神经退行性疾病,例如多发性硬化症 (MS)。一个长期的目标是直接检测和量化髓鞘含量,以促进髓鞘相关疾病的诊断和治疗。在我们的研究过程中,我们开发了一系列小分子探针 (SMP) 作为髓鞘成像剂。其中包括香豆素衍生物,其表现出良好的脑渗透性和髓鞘结合特性。在此,我们全面报道了基于香豆素的 SMP 作为髓鞘成像剂的设计和合成。

    The reaction between the carbonates of the light rare earths and ethylenediaminetetraacetic acid (EDTA) yields different forms of the protonated 1:1 rare earth-EDTA chelates depending on the temperature. Near room temperature, multihydrates are formed (H[Ln(EDTA)]·nH2O, where n = 7 or 5), while above 45°C H[Ln(EDTA)]·mH2O is formed where m = 1 or 0. These chelates have been characterized by i.r., TGA
