Inorganic reductants capable

The reaction of Ni " with [e, ]" produces Ni, which is a strong reductant capable of reacting rapidly with organic and inorganic oxidants. The reaction of Ni" " with Oj occurs via the formation of [NiOj]+. The Ni" " ion reacts with a-hy-droxyalkyl radicals via the formation of a Ni—C bond, e.g. ... 

Many organic and inorganic compounds, fibers, and particles are capable of damaging nucleic acids by generating reactive oxygen species via the reduction of dioxygen. These stimuli include different classes of organic compounds, classic prooxidants (anticancer antibiotics, various quinones, asbestos fibers, and so on), and even antioxidants, which can be oxidized in the presence of transition metal ions. 

More investigations of nitrogen reactions with transition metal compounds [162] confirmed the capability of nitrogen to readily enter reactions and reduction by many organometallic and inorganic coordination compounds of transition metals [163],...
