The mononuclear title compound, [Ti(C(5)H(10)NO(2))(4)], is a rare example of an eight-coordinate Ti(IV) compound in which all donor atoms are O atoms. The coordination geometry around Ti(IV) is pseudo-dodeca-hedral and the O-C-O angles of the carbamate ligands are slightly compressed [range 115.3 (2)-116.7 (2)°], apparently on account of the high coordination number. One ethyl group is disorde...

Purpose: To investigate the protective role of evodiamine, a naturally occurring anti-inflammatory, antioxidant, and anti-apoptotic compound, against cadmium-induced cytotoxicity in proximal tubular cells (human kidney 2; HK-2).
 Methods: HK-2 were treated with different concentrations evodiamine (5, 20, 50 ?M) for 2 h then incubated 40 ?M cadmium chloride another 24 h. Cell viability apop...

The use of substrate analogues as inhibitors provides a way to understand and manipulate enzyme function. Here we report two 1 A resolution crystal structures of liver alcohol dehydrogenase in complex with NADH and two inhibitors: dimethyl sulfoxide and isobutyramide. Both structures present a dynamic state of inhibition. In the dimethyl sulfoxide complex structure, the inhibitor is caught in t...

A series of cadmium thiolate compounds that feature a sulfur-rich coordination environment, namely [TmBut]CdSAr, have been synthesized by the reactions of [TmBut]CdMe with ArSH (Ar = C6H4-4-F, C6H4-4-But, C6H4-4-OMe, and C6H4-3-OMe). In addition, the pyridine-2-thiolate and pyridine-2-selenolate derivatives, [TmBut]CdSPy and [TmBut]CdSePy have been obtained via the respective reactions of [TmBu...

The title compounds, [CdBr2(C12H10N4O)]·CH3OH, (I), and [CdI2(C12H10N4O)], (II), are cadmium bromide and cadmium iodide complexes of the ligand (E)-N'-(pyridin-2-yl-methyl-ene)picolinohydrazide. Complex (I) crystallizes as the methanol monosolvate. In both compounds, the Cd2+ cation is ligated by one O atom and two N atoms of the tridentate ligand, and by two bromide anions forming a Br2N2O pen...

Inwardly rectifying K(+) currents are generated by a complex of four Kir (Kir1-6) subunits. Pore properties are conferred by the second transmembrane domain (M2) of each subunit. Using cadmium ions as a cysteine-interacting probe, we examined the accessibility of substituted cysteines in M2 of the Kir6.2 subunit of inwardly rectifying K(ATP) channels. The ability of Cd(2+) ions to inhibit chann...

Metal sulphides are highly important for the technology of semiconductor film materials. The potential these compounds has not been exhausted yet when it comes to creating optoelectronic devices, solar cells, and luminescent devices based on them. goal this work was determine nature interaction in polycrystalline layers CdS–MemSn, where Me metals groups I–VII periodic table. Cadmium sulphide ch...

Sulphur is an essential macroelement that plays important roles in living organisms. The thiol rich sulphur compounds, such as cysteine, γ-Glu-Cys, glutathione and phytochelatins participate in the tolerance mechanisms against cadmium toxicity. Plants, algae, yeasts and most prokaryotes cover their demand for reduced sulphur by reduction of inorganic sulphate. The aim of this study was to inves...
