2'-Deoxyguanosine monohydrate

2'-Deoxyguanosine monohydrate is a nucleoside composed of guanine and deoxyribose, and is one of the basic building blocks of DNA. In the oxidation reaction mediated by singlet oxygen 1O2, the guanine base of 2'-Deoxyguanosine is easily oxidized to generate two major products, 4,8-dihydro-4-hydroxy-8-oxodG and 7,8-dihydro-8-oxodG. The oxidation products of 2'-Deoxyguanosine monohydrate may participate in DNA damage, which may affect gene expression or induce cancer[1].
