Description
  • Inosine, an intermediate in purine metabolism, consists of hypoxanthine and ribose. It is an inert purine nucleoside formed by breakdown of adenosine (deamination, known as A-to-I editing that occurs in tRNA and mRNA) or also is generated by the action of 5'-nucleotidase on inosine monophosphate (IMP).
  • Inosine has neuroprotective, cardioprotective, immunomodulatory, anti-tumor and anti-inflammatory effects in different experimental models.
  • Inosine functions are mediated in receptor-dependent or-independent manners. The receptor-mediated function of inosine is thought to be related to adenosine receptor family members including A1, A2A, A2B, and A3 G-protein coupled receptors. It is an agonist for adenosine A1 (A1R) and A2A (A2AR) receptors.
  • Inosine is released from brown adipocytes (BAs) upon stress. Inosine activates purinergic P1 receptors, triggering BA activation and white adipocyte browning. Consequently, inosine increases whole-body energy consumption and alleviates diet-induced obesity in mice. Inosine and other closely related purines might be a novel approach to tackle obesity and associated metabolic disorders by enhancing energy expenditure. Inosine is a potent activator of brown adipose tissue and energy homeostasis.
