Chemical Properties
Crystalline
Uses
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). It has also been used as a standard for high performance liquid chromatography analysis.
Uses
An Inosine (I661000) analog with hypotensive activity. An impurity of the antiviral drug 2’,3’-Dideoxyinosine (D440950).
Definition
ChEBI: 2'-deoxyinosine is a purine 2'-deoxyribonucleoside that is inosine in which the hydroxy group at position 2' is replaced by a hydrogen. It has a role as a Saccharomyces cerevisiae metabolite, a human metabolite, a plant metabolite, an Escherichia coli metabolite and a mouse metabolite. It is a purines 2'-deoxy-D-ribonucleoside and a purine 2'-deoxyribonucleoside. It is functionally related to an inosine.
Biochem/physiol Actions
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′-deoxyinosine is formed from nitrosative deamination by N2O3.
