Dithiocarbomates are a class of sulfur-based metal-chelating compounds commonly used in industry, agriculture, and medicine. 2,6 di methoxy Aniline dithiocarbamate  Complexes of Copper and Ruthenium have been prepared  and Characterized by Spectroscopic methods like IR,NMR and also analysis of Biological activity. The investigation of these complexes confirmed that the stability of metal–ligands coordination through, S & S,N atoms as bidendate chelates..

Alt Activity

Cadmium is a dangerous occupational and environmental toxin. It accumulates in the human organism mainly in liver and kidneys. Cadmium half-life is about 10 years, so the symptoms of cadmium intoxication may occur several years after the exposure. Until now in treating intoxication with this metal chelating compounds have been used, burdened with numerous undesirable symptoms. In our investigations anthocyanins from Aronia melanocarpa were used to reduce the harmful results caused by cadmium. Administering anthocyanins with cadmium chloride resulted in a statistically significant decrease of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) activity, concentration of bilirubin and urea in blood serum and decreased cadmium cumulation in liver and kidneys in relation to animals receiving cadmium chloride only.

<div> <p>Positron emission tomography (PET), which uses positron-emitting radionuclides to visualize and measure processes in the human body, is a useful noninvasive diagnostic tool for Alzheimer’s disease (AD). The development of longer-lived radiolabeled compounds is essential for further expanding the use of PET imaging in healthcare, and diagnostic agents employing longer-lived radionuclides such as <sup>64</sup>Cu (t<sub>1/2</sub> = 12.7 h, β<sup>+</sup> = 17%, β<sup>-</sup> = 39%, EC = 43%, E<sub>max</sub> = 0.656 MeV) are capable of accomplishing this. One limitation of <sup>64</sup>Cu PET agents is that they could release free radioactive Cu ions from the metal complexes, which decreases the signal to noise ratio and accuracy of imaging. Herein, a series of 1,4,7-triazacyclononane (TACN) and 2,11-diaza[3.3]-(2,6)pyridinophane (N4)-based <a>metal-chelating compounds with pyridine arms were designed and synthesized by incorporating Aβ-interacting fragments into metal-binding ligands, which allows for excellent Cu chelation without diminishing their Aβ-binding affinity. </a>The crystal structures of the corresponding Cu complexes confirmed the pyridine N atoms are involved in binding to Cu. Radiolabeling and autoradiopraphy studies show that <a>the compounds efficiently chelate <sup>64</sup>Cu, and the resulting complexes exhibit specific binding to the amyloid plaques in the AD mouse brain sections vs. WT controls.</a></p> </div> <br>
