The paper is a review on the present data about the structure, properties and reactivity of bis(diselenocarbamato)copper(II), Cu(dsc)2, complexes which are significantly different form the remaining chelates with chromophores CuO4, CuN4 and CuS4 known up to now. The marked differences of Cu(dsc)2 are attributed to its specific electronic structure with dominating donor properties of the ligands...

A new method for the simultaneous determination of lead, cadmium and mercury ions in microwave-digested foodstuffs by reversed-phase high-performance liquid chromatography combined with on-line enrichment technique has been developed. The foodstuff samples were digested by microwave digestion. The lead, cadmium and mercury ions can be precolumn derivatized with 5,10,15,20-tetrakis(3-aminophenyl...

We describe a simple hybridization assay performed in microtitration wells with use of DNA probes labeled with three different lanthanide chelates for detection of seven mutations that cause cystic fibrosis. The assay is based on DNA amplification of four fragments containing the mutations (delta F508, G1717-->A, G542X, R553X, 3905 insertion T, W1282X, and N1303K) by PCR, followed by hybridizat...

Several polynuclear Pt(II) chelates with biogenic polyamines were synthesized and screened for their potential antiproliferative and cytotoxic activity in different human cancer cell lines. To gather information regarding the structure-activity relationships underlying their biological activity, the complexes studied were designed to differ in geometrical parameters such as the nature of the li...

Metal-carboxylic ionophore complexes, where Metal = Ag, Tl, Li, Na, K, Rb, Mg, Mn, Cs, Sr, Ba, Cu and Ionophore = monensin (MON-H), have been synthesized. The molecular structures of three complexes have been solved by X-ray diffraction methods. The metal chelates were tested against human tuberculosis line for potential anti-tubercular activity against Mycobacterium tuberculosis H37Rv (MTB). T...

Heavy metals are among the most widespread pollutants in soil. Phytoextraction technology is used to solve problem of multi-metal-contaminated The efficiency this process can be increased by introducing various amendments. A soil amendment any material added a improve its physical properties, such as water retention, permeability, infiltration, drainage, aeration, and structure. Some chemical a...

Since the advancement by Smith et al. (l-4) of the theory that metal ions are chelated simultaneously to enzyme protein and substrate in various polypeptidases, the nature of metal binding to peptides and proteins has become an important as well as an interesting problem. The chelate structures proposed by Smith (3), and later somewhat revised (5, 6), indicate that the metal is bound, at least ...
