Dithiocarbamates and iron chelators were recently considered for the treatment of AIDS and neurodegenerative diseases. In this study, we show that dithiocarbamates and metal chelators can potently block the activation of nuclear factor kappa B (NF-kappa B), a transcription factor involved in human immunodeficiency virus type 1 (HIV-1) expression, signaling, and immediate early gene activation d...
A series of triorganotin dithiocarbamates R3SnS2CNR′2 (R = Cy, Ph; NR′2 = NEt2, N(n-Bu)2, N(i-Bu)2, N(n-Pr)2, N(CH2)5, NH(n-Pr), NH(n-Bu), NH(i-Bu)) has been synthesized using a low-temperature method. Their structures have been characterized by IR, Mössbauer and NMR spectroscopies. In the solid state, an unsymmetrical chelation of the dithiocarbamate ligand was found in all the compounds synth...
Residents of Qidong, People's Republic of China, are at high risk for development of hepatocellular carcinoma, in part due to consumption of aflatoxin-contaminated foods, and are exposed to high levels of phenanthrene, a sentinel of hydrocarbon air toxics. Cruciferous vegetables, such as broccoli, contain anticarcinogens. Glucoraphanin, the principal glucosinolate in broccoli sprouts, can be hy...
A small set of unsymmetrically substituted acene derivatives containing either aniline or dithiocarbamate moieties was synthesized. A stepwise, one-pot procedure was used to transform appropriate acenequinones to aniline-linked acenes in one step with moderate yields. A heretofore-unreported carbon disulfide activation process involving the formation of a trialkylammonium dithiocarbamate interm...
The reactivity of 2-deoxy-2-iodoglycosyl isothiocyanates toward O- and S-nucleophiles gives an easy access to 2-deoxy-2-iodoglycopyranosyl thiocarbamates and dithiocarbamates. Internal nucleophilic displacement of the iodine by the sulfur atom in these compounds allows the preparation of glycopyranoso[1,2-d]-1,3-thiazoles and glycopyranoso[1,2-d]-1,3-thiazolidin-2-one or -2-thione. Reaction wit...
A brief historical resume is presented on the use of dithiocarbamates for the treatment of persons exposed to nickel carbonyl. The specificity of the treatment is demonstrated in an industrial accident in which four men were simultaneously exposed to nickel carbonyl vapors. Three of the men received dithiocarb within 24 hours after exposure and the fourth was hospitalized by his family physicia...
In the last decade, ionic liquids have shown great promise in a plethora of applications. Nevertheless, little attention has been paid to the characterization of the purity of these fluids, which ultimately lead to non-reproducible data in the literature. Derivatization with carbon disulfide is used to quantitatively determine primary and secondary non-aromatic amines (detection limit: 0.2 wt%)...
Reductive desulfurisation of dithiocarbamates is conveniently achieved using H(3)PO(2)-Et(3)N-ACCN in refluxing dioxane. Fused and spirocyclic β-lactams, prepared through 4-exo trig carbamoyl radical cyclisation-dithiocarbamate group transfer reactions, are reduced without fragmentation of the strained 4-membered ring. Diethyl tetraacetyl-d-glucopyranosyl dithiocarbamate is selectively reduced ...
