Inosine

 

(hypoxanthine riboside), a nucleoside consisting of the nitride purine base hypoxanthine and the carbohydrate ribose. Inosine is the intermediate product of nucleic acid metabolism. It is formed in the organism during the deamination of adenosine and also by synthesis from a free base according to the reaction hypoxanthine + ribose- 1 -phosphate ⇆ inosine + phosphate. This reversible reaction is catalyzed by the enzyme nucleoside phosphorylase.

This suggests that MPNs were preferentially methylated by thiopurine methyltransferase between 6 and 20 h, rather than converted by inosine monophosphate dehydrogenase and guanosine monophosphate synthetase into TGNs.
Pharmacodynamic assessment of mycophenolic acid-induced immunosuppression by measurement of inosine monophosphate dehydrogenase activity in a canine model.
Its immunosuppressive activity is thought to reside in the inhibition of inosine monophosphate dehydrogenase (IMPDH), leading to a suppression of purine nucleotide synthesis in lymphocytes, thereby suppressing cell mitosis (3, 4).
