8-OXO-2'-DEOXYGUANOSINE

Description

8-Oxo-2′-deoxyguanosine (88847-89-6) is a useful marker for DNA damage via a variety of oxidative processes.1?It is a critical biomarker for oxidative stress and carcinogenesis.2,3

Chemical Properties

White Crystalline Solid

Uses

8-Hydroxy-2′-deoxyguanosine has been used:

• as a standard to analyse the oxidative DNA damage in the placenta of normal and abnormal pregnancies by electrochemical detection
• as a standard for high performance liquid chromatography (HPLC) with electrochemical detection (ECD) measurement
• as a standard for HPLC and as a urinary marker of oxidative stress in order to assess the potential?antioxidant?activity of green coffee bean extract (GCBE) in vivo
• as a standard for LC/MS/MS analysis

Uses

A marker compound indicative of DNA damage associated with mutagenesis and carcinogenesis. Can induce differentiation of Friend murine erythroleukemia cells in vitro.

Definition

ChEBI: Guanosine substituted at the purine 8-position by a hydroxy group. It is used as a biomarker of oxidative DNA damage.

Biochem/physiol Actions

A marker compound typically indicative of DNA damage associated with mutagenesis and carcinogenesis
