Novos ditiocarbamatos de metais de transição do tipo [M 2 (etdtc) 2 ] e [M(etdtc)Cl] 2 [M = Mn(II), Fe(II), Co(II), Ni(II), Cu(II), Zn(II), Cd(II) e Hg(II), M = Cr(III), Fe(III) e etdtc = (S 4 N 4 C 11 H 18 )] foram sintetizados por meio de técnicas de automontagem. Os ditiocarbamatos metálicos foram preparados a partir da amina primária, CS 2 e cloreto metálico. Foram caracterizados por técnic...

BACKGROUND Allergic contact dermatitis caused by rubber gloves is not infrequent, and has almost exclusively been attributed to contact sensitization to accelerators. Thiurams have been the most frequent allergens, followed by dithiocarbamates. OBJECTIVES To describe the current allergen pattern in patients with occupational allergic contact dermatitis caused by rubber gloves. METHODS This ...

Isothiocyanates occur in many edible plants and are consumed in substantial quantities by humans. A number of isothiocyanates block chemical carcinogenesis in a variety of animal models by inhibiting Phase 1 enzymes involved in carcinogen activation and by inducing Phase 2 enzymes that accelerate the inactivation of carcinogens. There are large but unexplained potency differences among individu...

In this study ready-to-eat food samples were collected in the production line of the university restaurant of the University of Brasilia, Brazil, which serves non-vegetarian and vegetarian meals daily. Samples were analysed for the presence of ten organophosphorus insecticides (OPs) by GC/FPD, after extraction with ethyl acetate and anhydrous sodium sulfate (LOQ = 0.002 mg kg(-1)), and for dith...

The X-ray structural chemistry of zinc and cadmium 1,1-dithiolates (for example, xanthate, dithiophosphate and dithiocarbamate) with potentially bridging bipyridyl-type ligands (for example, 4,4′-bipyridine) is reviewed. For zinc, the xanthates and dithiophosphates uniformly form one-dimensional coordination polymers, whereas the zinc dithiocarbamates are always zero-dimensional, reflecting the...
