BACKGROUND Aberrant biometal metabolism is a key feature of neurodegenerative disorders including Alzheimer's and Parkinson's diseases. Metal modulating compounds are promising therapeutics for neurodegeneration, but their mechanism of action remains poorly understood. Neuronal ceroid lipofuscinoses (NCLs), caused by mutations in CLN genes, are fatal childhood neurodegenerative lysosomal storag...

A dehydroabietyl derivative 2 bearing a 2-(2'-hydroxyphenyl)benzimidazole unit was synthesized and its sensing behaviors toward metal ions were investigated by UV-Vis and fluorescence spectroscopy methods. In THF solution, compound 2 exhibited excellent selectivity for CuII over miscellaneous other metal ions including CrII, MnII, CoII, NiII, ZnII, CdII, AlIII, MgII, PbII, HgII, NaI, LiI and KI...

A partial least-squares multivariate calibration method for the resolution of mixtures of metal ions from the spectra of the complexes produced in a flow injection (FI) system has been developed. The method has been applied to the simultaneous determination of Cull and Znii with 4-(4'-methyl-2'-thiazolylazo)-2-methylresorcinol. The reagent exhibits a high absorbance and its spectrum strongly ov...

Coconut water (Cocos Nucifera) is shown to be a source of essential elements present in the form low-molecular weight stable complexes known for their bio-availability. The total element concentrations were range 0.2–2.7, 0.3–1, 3–14 and 0.5–2 ppm Fe, Cu, Mn, Zn, respectively, varied as function origin nut its maturity. Speciation was investigated by size-exclusion chromatography - inductively ...

We report on the synthesis and crystal structure of solvent-free coordination polymer CoII(2,5-DMT) (1) with 2,5-DMT ≡ 2,5-dimethoxyterephthalate which is isostructural to already reported MnII ZnII congeners (C2/c, Z = 4). In contrast, for M MgII, a MOF DMF-filled pores obtained, namely Mg2(2,5-DMT)2(DMF)2 (2) (P1¯, 2). Attempts remove these solvent molecules record gas sorption isotherm did n...
