2'-Deoxyinosine (Standard)

2'-Deoxyinosine (Standard) is the analytical standard of 2'-Deoxyinosine (HY-W008638). This product is intended for research and analytical applications. 2'-Deoxyinosine is the major product of 2'-deoxyadenosine in the absence of deoxycoformycin. 2'-Deoxyinosine is found to be associated with purine nucleoside phosphorylase (PNP) deficiency^[1]. In Vitro:In the absence of deoxycoformycin, 2’-deoxyadenosine is primarily deaminated to 2’-deoxyinosine and then converted into hypoxanthine. In the presence of the inhibitor, the deoxynucleoside, in addition to a phosphorylation process, undergoes phosphorolytic cleavage giving rise to adenine. The conversion of 2’-deoxyadenosine to adenine might represent a protective device, emerging when the activity of adenosine deaminase is reduced or inhibited. There is much evidence to indicate that the enzyme catalyzing this processs may be distinct from methylthioadenosine phosphorylase and S-adenosyl homocysteine hydrolase, which are the enzymes reported to be responsible for the formation of adenine from 28-deoxyadenosine in mammals^[1].
