2’-Deoxyguanosine N1-(Ethyl Acrylate) is an intermediate in the synthesis of 3-(2-Deoxy-β-D-erythro-pentofuranosyl)-3,5-dihydropyrimido[1,2-a]purine-6,10-dione (D235185). 3-(2-Deoxy-β-D-erythro-pentofuranosyl)-3,5-dihydropyrimido[1,2-a]purine-6,10-dione is likely an endogenous biomarker in humans and is readily generated from M1dG in liver cytosol, which involves xanthine oxidase and aldehyde oxidase.
