چکیده
The highly cytotoxic diruthenium complex [(p-MeC(6)H(4)Pr(i))(2)Ru(2)(SC(6)H(4)-p-Me)(3)](+) (1), water-soluble as the chloride salt, is shown to efficiently catalyze oxidation of the thiols cysteine and glutathione to give the corresponding disulfides, which may explain its high in vitro anticancer activity.

Efficient oxidation of sulfides using a molybdenum(VI)–dioxo complex containing an benzimidazole ligand
For the first time, dioxomolybdenum(VI) complex with the general formula [MoO2L2] containing a N-O bidentate ligands (HL=2-(o-aminophenyl)- benzimidazole) has been used for the oxidation of sulfides. Elemental analyses (carbon, hydrogen, nitrogen), FT-IR and Uv-Visble spectra and 1HNMR analysis agree well with the proposed stoicheiometry of the complex [MoO...
