Alpha-synuclein filaments are the major component of intracytoplasmic inclusion bodies characteristic of Parkinson's disease and related disorders. The process of alpha-synuclein filament formation proceeds via intermediate or protofibrillar species, each of which may be cytotoxic. Because high levels of calcium(II) and other metal ions may play a role in disease pathogenesis, we investigated t...

The complete amino acid sequence of human plasma apolipoprotein C-II isolated from normal individuals and a subject with type V hyperlipoproteinemia has been determined. Apo-C-II contains 79 amino acids with the following amino acid composition: Asp4, Asn1, Thr9, Ser9, Glu7, Gln7, Pro4, Gly2, Ala6, Val4, Met2, Ile1, Leu8, Tyr5, Phe2, Lys6, Arg1, Trp1. Cleavage of apo-C-II by cyanogen bromide pr...

Catalytic oxidation of N,N'-dimethylthiourea and thiourea by dioxygen in water using a new cobalt(II) complex of octasulfophenyltetrapyrazinoporphyrazine was performed under mild conditions. The reaction is shown to include the formation of an intermediate anionic five-coordinate complex followed by an unusual two-electron oxidation to produce the corresponding urea and elemental sulfur (S8). K...

An amine-templated cobalt(II) sulfate with the kagome lattice, prepared for the first time, exhibits magnetic properties comparable to those of the analogous Fe(III) compounds.

In an effort to develop new tripodal N-heterocyclic carbene (NHC) ligands for small molecule activation, two new classes of tripodal NHC ligands TIME and TIMEN have been synthesized. The carbon-anchored tris(carbene) ligand system TIME (R = Me, t-Bu) forms bior polynuclear metal complexes. While the methyl derivative exclusively forms trinuclear 3:2 complexes [(TIME)2M3] 3+ with group 11 metal ...

A unique case of a grid-of-mesocates sequentially assembled by supramolecular cobalt(II) meso-helical units connected through hydrogen bonding is reported.

The title Cu(II) complex, [CuBr(2)(C(21)H(15)N(3))]·0.5H(2)O, was obtained by the hydro-thermal reaction of copper(II) bromide, 4'-phenyl-2,2':6',2''-terpyridyl (4'-Ph-terpy or L) and sodium citrate in water in 31% yield. There are two unique complex mol-ecules and a water mol-ecule in the asymmetric unit. The Cu(II) cation is ligated by three N atoms of L and two bromide anions, forming an irr...
