Eight different zirconium phenoxyimine complexes were synthesized, characterized and tested as catalysts for ethylene polymerization. The phenoxyimine compounds were prepared by condensation of substituted salicylaldehydes with aliphatic and aromatic amines, the substituted salicylaldehydes from ortho substituted phenols and paraformaldehyde. The introduction of iodo substituents was achieved e...

Zaman M.Z., Bakar F.A., Selamat J., Bakar J.. (2010): Occurrence of biogenic amines and amines degrading bacteria in fish sauce. Czech J. Food Sci., 28: 440–449. The contents of biogenic amines histamine, putrescine, and cadaverine in fish sauce were determined and the bacteria isolated from the samples were evaluated for their amines degradation activity. Five fish sauce samples contained 62.5...

Here, we report on a procedure in which ultrasonic waves were used to mix a water-ionic liquid two-phase system to simultaneously derivatize amines with dansyl chloride and extract, and the resulting dansyl amines into an ionic liquid (IL) at room temperature within 15 min. The ILs used were room-temperature ionic liquids (RTILs), such as 1-alkyl-3-methylimidazolium hexafluorophosphate ([C(n)MI...

The effects of intraperitoneal injections of various doses of A9-tettahydrocannabinol (A”-THC) on brain levels of cyclic adenosine 3’,5’-monophosphate (cyclic AMP) have been studied in mice. Doses of A9-THC in the range of 0.1 to 1.0 mgikg cause a 5&160 per cent elevation of cyclic AMP levels compared to controls (P < O.OOOS), while doses of A9THC in the range of 2.0 to 10.0 mg/kg cause a 3@-60...

The first one-pot selective synthesis of unsymmetric tertiary amines is reported by the amination of two types of alcohols with primary amines via the development of a simple CuAlOx-HT catalyst and enables the synthesis of unsymmetric amines in a wide variety of primary amines and alcohols.

1. The relationships between nutritional state, lipoprotein lipase activity in epididymal fat-pads, and the concentrations of glucose, insulin and unesterified fatty acids in the plasma were studied in rats that had been adapted for 3 weeks to one of two controlled feeding schedules. In one of these, rats had access to food for 14h during each 24h period, and in the other, they had access to fo...

Human erythrocytes have been used as a model for evaluating the chemical carcinogen-plasma membrane interaction. The carcinogenic aromatic amines 2-acetylaminofluorene, dimethylaminoazobenzene, and 3'-methyldimethylaminoazobene stabilize erythrocytes against lysis in hypotonic solution. In general, the stabilization potential of these compounds reflects their oil:water partition coefficients an...

Over the years, methods have been developed for the preparation of quaternary ammonium compounds, which are important as organic intermediates, detergents, insecticides, bacteriostats, and drugs [1, 2]. The most common method for preparation of these compounds is by alkylation of tertiary amines [3, 4]. Primary and secondary amines have also been quaternized, albeit less frequently [3, 4], due ...

Molybdenum-containing enzymes, aldehyde oxidase and xanthine oxidase, are important in the oxidation of N-heterocyclic xenobiotics. However, the role of these enzymes in the oxidation of drug-derived aldehydes has not been established. The present investigation describes the interaction of eleven structurally related benzaldehydes with guinea pig liver aldehyde oxidase and bovine milk xanthine ...
