In the title complex, [ZnCl2(C13H17N3)], the coordination sphere of the zinc cation is distorted square pyramidal. The three N atoms of the N,N',N''-tridentate 8-[2-(di-methyl-amino)-ethyl-amino]-quinoline ligand and one chloride ion constitute a considerably distorted square base. The apical site is occupied by another chloride ion. The distortion from the ideal square-pyramidal geometry is ma...

The effect of the C-terminal octapeptide of cholecystokinin-pancreozymin (CCK-PZ), caerulein, and the C-terminal tetrapeptide of gastrin on pancreatic secretion of fluid, electrolyte, amylase, and protein was studied in anaesthetized dogs prepared with pancreatic fistulae. Against background stimulation of fluid secretion with submaximal doses of secretin, all the polypeptides produced a qualit...

The concentrations of zinc, copper, iron, nickel, cadmium, lead, manganese, sodium and chloride in the sweat of six males and three females were determined after collections utilizing a total body washdown technique. From our results, sweat appears to be an important excretory pathway for zinc and copper. The mean concentrations of nickel and cadmium in sweat were higher than those reported for...

chloride or cadmium nitrate. However, the complexation was secondary in relation to ninhydrin-amino acid reaction [4]. At the end of the 1990’s, a new component named 1,2-IND (1,2-indanedione) was applied, which reacted with amino acids and with DFO, whereby the reaction product exhibited fluorescent properties [5, 6]. The follow-up scientific activity within this scope was focused on the optim...

Thermal decomposition of layered zinc hydroxide double salts provides an interesting alternative synthesis for particles of zinc oxide. Here, we examine the sequence of changes occurring as zinc hydroxide chloride monohydrate (Zn5(OH)8Cl2·H2O) is converted to crystalline ZnO by thermal decomposition. The specific surface area of the resultant ZnO measured by BET was 1.3 m(2) g(-1). A complicati...

A convenient zinc(II) chloride-catalyzed regioselective propargylation/amination/cycloisomerization process has been developed for the synthesis of substituted pyrrole derivatives from propargylic acetates, enoxysilanes and primary amines. Various aromatic and aliphatic propargylic acetates participate well in the reaction, providing the propargylation/amination/cycloisomerization products in g...
