Seven reported xanthate ligands and their new Fe(II) complexes of formulaNa[Fe(R-OCSS)3], where R is ethyl-, propyl-, butyl-, pentyl-, Hexyl-, heptyl- and octyl-xanthate have been synthesized. They have been characterized using elemental analysis, molar conductance, FT-IR, UV-Vis and 1H NMR spectroscopic techniques and melting-, decomposition-points for ligand...

Background: Alzheimer’s disease (AD) is a neurodegenerative disease characterized by decreased cognitive function in patients due to forming Aβ peptides and neurofibrillary tangles (NFT) in the brain. Therefore, the need to develop new treatments can reduce this risk. Acetylcholinesterase is one of the targets used in the design of new drugs for the treatment of AD. The researchers obtain new i...

analysis of  receptor–ligand  interactions  in  the  context  of  diseases  necessitates  to understand how hla–kir genotypes function in diseases. although cd56+  lymphocytes are derived from multiple lineages, they share a functional association with immunosurviellance and antimicrobial responses. the present study aimed to determine whether kir phenotype in cd56 lymphocytes and corresponding...

the stability constants of species present in the systems ni(ii)-pyridoxamine(pym)(a) and ni(ii)-pyridoxamine(pym)(a)-imidazole containing ligands(b) [b = imidazole(him),  benzimidazole(bim), histamine(hist) and l-histidine(his)] have been determined ph-metrically using the miniquad computer program. the existence of the species niah, nia and nia2 was proven for the ni(ii)-pym(a) system, wherea...

uv/tio2 photocatalysis of chelated copper in aqueous solutions has been performed starting from cu(ii)-tartaric acid, cu(ii)-citric acid, cu(ii)-edta and cu(ii)-dtpa,in the presence of oxygen and at acidic ph. the photocatalytic reaction obeys first-order kinetic equation. the influence of cu(ii) on photocatalytic oxidation of organic ligands and how the various organics will affect the treatmen...

context: in recent years, nanotechnology has opened up several new avenues of extraordinary biomedical potential by modulating metals into their nanosize leading to significant improvement in their chemical, physical and optical properties. introduction: the advanced fabrication techniques have been exploited to modify nanostructured materials. the functionalized nanoscaled fibers display vario...

two n4-type schiff base ligands named n,n'-bis(2-pyridylmethylidene)-1,2-diiminoethane (l1) and n,n'-bis(2-pyridylmethylidene)-1,3-diiminopropane (l2) have been synthesized by the reaction of pyridine-2-carbaldehyde with ethylenediamine and propylenediamine, respectively. the binding abilities of l1 and l2 in dichloromethane towards cu2+, cd2+, co2+, ni2+, zn2+ and pb2+ ions were evaluated by p...

calcification and inflammation are among the important cases of exudative age-related macular degeneration (e-armd). the aim of the present study was to elucidate if there is any relationship between serum osteoprotegerin (opg), soluble receptor activator of nuclear factor-kappa b ligand (rank-ligand) and e-armd. in a cross-sectional study, we compared 45 e-armd patients with 45 matched control...

The synthesis, characterization and quantum-chemical investigations of two new Co(II) complexesderived from fluorescent benzimidazoles have been reported. Two new fluorescentheterocyclic ligands were synthesized from the reduction of imidazo[4',5':3,4]benzo[1,2-c]isoxazole derivatives, and characterized by elemental analyses, IR, mass, and NMR spectra. Coordination of the bidentate ligands ...
