Application

2′-Deoxyinosine has been used in the quantification of nucleoside forms of DNA lesion in a single DNA sample by liquid chromatography tandem mass spectrometry (LC-MS/MS).[1] It has also been used as a standard for high performance liquid chromatography analysis.[2]

Biochem/physiol Actions

2′-Deoxyinosine is a nucleoside composed of hypoxanthine attached to 2′-deoxyribose via a β-N9-glycosidic bond. 2′-Deoxyinosine in DNA can arise from deamination of adenosine. 2′-deoxyinsine can be used as a model compound to study the chemistry of adduct formation and radical chemistry that may affect DNA structures. 2′-Deoxyinosine is used to produce hybridization-sensitive fluorescent DNA probes with self-avoidance ability.
2′-Deoxyinosine is a nucleoside form of hypoxanthine. It is a DNA damage product resulting from the impairment of DNA by reactive nitrogen species.[2] 2′-deoxyinosine is formed from nitrosative deamination by N2O3.[1]

Hybridization-sensitive fluorescent probes have an inherent disadvantage: self-dimerization of the probe prevents the fluorescence quenching prior to hybridization with the target, resulting in a high background signal. To avoid self-dimerization of probes, we focused on a base pair formed by

Deoxyinosine (dI) in DNA can arise from hydrolytic or nitrosative deamination of deoxyadenosine. It is excised in a repair pathway that is initiated by endonuclease V, the nfi gene product, in Escherichia coli. Repair was studied in vitro using M13mp18

Nature protocols, 1(4), 1995-2002 (2007-05-10)
Several studies examining DNA deamination have published levels of 2'-deoxyinosine that illustrated a large variation between studies. Most of them are the result of artifactual DNA deamination that occurs during the process of sample preparation, particularly acid hydrolysis. This protocol
