Metabolite Identification
Common Name2'-O-Methyladenosine
Description2'-O-Methyladenosine is a methylated adenine residue. 2'-O-Methyladenosine is a naturally occurring 2'-O-methylpurine nucleoside with long lasting hypotensive properties; resistance of 2'-O-methyladenosine against adenosine deaminase is thought to contribute to prolonged activity. 2'-O-Methyladenosine occurs in human fluids, and they increase in urines of untreated adenosine deaminase (ADA) deficient patients (OMIM 608958 ).
