  • Inosine is commonly found in tRNAs and is essential for proper translation of the genetic code in wobble base pairs . (wikidoc.org)
  • However, inosine pairs preferentially with cytidine (C) and its introduction to RNA, e.g. by the action of ADARs, thereby destabilizes double stranded RNA by changing AU base-pairs to IU mismatches (Bass and Weintraub, Cell, 1988). (wikidoc.org)

  • Lastly, inosine also results from the dephosphorylation of ATP -- the cellular currency of exercise. (tigerfitness.com)
  • Due to this, several fitness experts have claimed that supplementing with inosine can improve energy production and overall performance during exercise. (tigerfitness.com)
  • Inosine was initially considered as a means to boosting exercise performance by Eastern sports scientists in the 70s. (tigerfitness.com)
  • Suffice it to say, thought that there has been a severe lack of research regarding inosine and exercise performance, despite claims made by some in the fitness community that it helps improve performance. (tigerfitness.com)

  • Activation of 6-mercaptopurine occurs via hypoxanthine-guanine phosphoribosyltransferase (HGPRT) and a series of multi-enzymatic processes involving kinases to form 6-thioguanine nucleotides (6-TGNs) as major metabolites (See Metabolism Scheme in Figure 1). (nih.gov)
