Ru360 is an oxo-bridged dinuclear ruthenium ammine complex with an absorption spectrum maximum at 360 nm. It is an analog of ruthenium red, a well-known effective inhibitor of the mitochondrial calcium uniporter.^[1]

Ru360 was discovered after scientists found that commercial preparations of ruthenium red were often less than 20% pure, and that the crude mixture produced a stronger inhibition than the purified product.^[2] This component was later isolated and identified as Ru360.^[1]

Since Ru360 inhibits the flow of calcium into mitochondria, which can prevent the opening of the mitochondrial permeability transition pore, it has been investigated as a therapeutic treatment for stroke and heart attack.^[3]
