The i.m. injection of dimethyl sulfoxide prior to the infection of quail with Rous sarcoma virus strain 0 and of mice with Moloney sarcoma virus resulted in increased virus titers, decreased incubation time to tumors and, in the case of Moloney sarcoma virus, decreased spontaneous regressions. Dimethyl sulfoxide administered at the time of or after infection was without effect. This compound al...

The degradation of fenamiphos, fenamiphos sulfoxide, and fenamiphos sulfone was determined in a greenhouse experiment using autoclaved and nonautoclaved soil from field plots treated or not treated with fenamiphos. Fenamiphos degradation and formation of fenamiphos sulfoxide was faster in uonautoclaved soil than in autoclaved soil. In nonautoclaved soil, previous exposure to fenamiphos was asso...

L-Methionine-dl-sulfoxide can support the growth of an Escherichia coli methionine auxotroph, suggesting the presence of an enzyme(s) capable of reducing the sulfoxide to methionine. This was verified by showing that a cell-free extract of E. coli catalyzes the conversion of methionine sulfoxide to methionine. This reaction required reduced nicotinamide adenine dinucleotide phosphate and a gene...

In this article we present the synthesis of enantiomerically pure sulfoxide and study the influence of this compound on hemostasis. Detailed NMR studies and molecular dynamics simulations using sodium dodecyl sulfate (SDS) membrane models indicated that the bicyclic fragment of sulfoxide was embedded into the SDS micelle whereas the -SO(CH2)2OH fragment remained on the surface of the micelle an...

In this report a short and efficient synthesis of the dibenz[b,f]oxepin framework through intramolecular SNAr and McMurry reactions is described. The diaryl ethers required for the McMurry reaction have been obtained in good yields under microwave-assisted conditions of the reaction of salicylaldehydes with fluorobenzaldehydes without catalysts. Application of an intramolecular McMurry reaction...

A series of bulky monodentate phosphoramidite ligands were synthesized from chiral 3,3'-diaryl substituted BINOL derivatives and achiral or dendritic amines in good yields. Asymmetric hydrosilylation of styrenes with trichlorosilane in the presence of palladium complexes of these bulky ligands gave chiral silanes in high yields with excellent activity and productivity. Oxidation of these chiral...

Symmetric and asymmetric chalcogenides of organic nature are a class organometallic compounds that widely used as intermediates in number reactions, ligands the chemistry coordination compounds, they have wide range biological activity. Diaryl tellurides, which important for formation new carbon-carbon bonds, special area organotelluric compounds. The synthesis representatives this tellurium-co...

The sulfur K-edge X-ray absorption near edge spectra (XANES) of the hexakis(dimethyl sulfoxide) solvated trivalent group 13 ions, Al, Ga, In and Tl, in the solid state show larger splitting and different intensity distribution of the main sulfur 1s electronic excitations than for the uncoordinated dimethyl sulfoxide molecule. The transitions have been interpreted by density functional calculati...
