Free radical-mediated oxidative stress has been implicated in numerous autoimmune disorders including Graves’ disease. Hyperthyroidism results in a marked increase in intracellular antioxidant enzymes including superoxide dismutase. The later activity is significantly increased in untreated Graves’ patients while treatment with methimazole results in normalization of the free radical and antioxidant...
Methimazole (MeimzH) is an anti-thyroid drug and the first choice for patients with Grave’s disease. Two new copper(II) complexes of this drug: [Cu(MeimzH)2(NO3)2].0.5H2O and [Cu(MeimzH)2(H2O)2](NO3)2·H2O were synthesized and characterized by elemental analysis, dissolution behavior, thermogravimetric analysis and UV-vis, diffuse reflectance, FTIR and EPR spectroscopies. As it is known that copper(II)...
The coordination behavior of copper(II) with tricarballylic acid (H 3 TCA) and imidazole (Imz) is described. Speciation in aqueous solution has been determined at 25°C and 0.15M NaCl ionic strength by potentiometric measurements and EPR characterization of the species. Two new compounds CuTCAH·3H 2 O and CuTCAHImz·2H 2 O were obtained and characterized by elemental analysis...
