  <name>8-Hydroxyguanine</name>
  <description>Formation of 8-hydroxyguanine (8-OHG), a mutagenic base which is a marker for OH-mediated DNA damage, requires peroxidase and halides and occurs in the presence of transition metal chelators (DTPA +/- desferrioxamine), and is inhibited by catalase, superoxide dismutase (SOD), and scavengers of hypohalous acids. (PMID 10820020)
8-Hydroxyguanine is an oxidative stress marker for diagnosis of Alzheimer's disease (AD). (PMID 15977989) [HMDB]</description>
