Compared to the inert and highly cytotoxic dinuclear p-cymene ruthenium trithiolato complexes, the less cytotoxic mono- and dithiolato complexes readily hydrolyse in aqueous solution and form adducts with cysteine, but do not interact with DNA.

Electron Reduction

A preliminary study has been made of the oxidation of four octahedral RuII complexes in aqueous solution, particularly by H2O2. Kinetic measurements and simple experiments such as electrolytic oxidation followed by reduction with H2O2 have been used to obtain evidence for the mechanism of H2O2 decomposition when catalysed by the ruthenium complexes. The main course of the catalysis appears to consist in oxidation of RuII to RuIV with a corresponding reduction of H2O2 to hydroxyl ions, followed by a "electron reduction of RuIV to RuII with oxidation of H2O2 to O2 and hydrogen ions.

Fractured Surface

The freeze etching technique is potentially useful for examining dilute solutions or suspensions of macromolecular materials. Quick freezing of aqueous solutions in Freon or propane at or near liquid nitrogen temperature produces relatively large ice crystals and these crystals may damage the structures to be examined. Cryoprotective agents may reduce damage to the specimem, hut their use often results in the formation of a different set of specimem artifacts.In a study of the structure of polyethylene oxide gels glycerol and sucrose were used as cryoprotective agents. The experiments reported here show some of the structures which can appear when these cryoprotective agents are used.Figure 1 shows a fractured surface of a frozen 25% aqueous solution of sucrose. The branches of dendritic ice crystals surrounded hy ice-sucrose eutectic can be seen. When this fractured surface is etched the ice in the dendrites sublimes giving the type of structure shown in Figure 2. The ice-sucrose eutectic etches much more slowly. It is the smooth continuous structural constituent surrounding the branches of the dendrites.
