  • Publication number: 20080096846
    Abstract: A ruthenium (II) compound of formula (I): or a solvate on prodrug thereof, wherein: R1, R1, R3, R4, R5 and R6 are independently selected from H, C1-7 alkyl, C5-20 aryl, C3-20 heterocyclyl, halo, ester, amido, acyl, sulfo, sulfonamido, ether, thioether, azo, amino, or R1 and R2 together with the ring to which they are attached form a saturated or unsaturated carbocyclic or heterocyclic group containing up to three 3- to 8-membered carbocyclic or heterocyclic rings, wherein each carbocyclic or heterocyclic ring may be fused to one or more other carbocyclic or heterocyclic rings; X is a neutral or negatively charged N- or S-donor ligand; Y is a counterion; in is 0 or 1; q is 1, 2 or 3; C? is C1-12 alkylene bound to two A groups; p is 0 or 1 and r is 1 when p is 0 and r is 2 when p is 1; and A and B are each independently O-donor, N-donor or S-donor ligands, and may be connected to one another. The compounds are used in cancer therapy.

  • Patent number: 5807473
    Abstract: An apparatus and method for electrolytically treating water which includes one or more reactors. Each reactor has a liquid containing vessel and one or more pairs of electrodes. The electrodes are suitable for a continuous anodic or cathodic operation for treating water. A power source for each reactor provides voltage and current to the electrodes. A controller maintains the voltage and current provided to the electrodes. The duration of each voltage polarity applied to each electrode is substantially the same. The polarity of the voltage to the electrodes is periodically reversed during which there is a period of zero voltage applied to the electrodes between a first polarity and a second polarity. The period of zero voltage results in a substantial reduction of back e.m.f. of the reactor which enhances the service life and efficacy of the electrodes.
