Deoxyguanosine is a nucleoside consisting of the base guanine and the sugar deoxyribose. It is like guanosine but with one oxygen atom removed. It is a nucleoside component of DNA. Deoxyguanosine can be converted to 8-hydroxy-deoxyguanosine (8-OHdG) due to hydroxyl radical attack at the C8 of guanine.

6,6'-Dithiodinicotinic Acid is a non permeant thiol agent which affects several mitochondrial functions. In rat liver mitochondria, 6,6'-Dithiodinicotinic Acid inhibits only the Pi/OH- carrier; both 6,6'-Dithiodinicotinic Acid and n-butylmalonate are necessary to inhibit completely Pi entry.
