Application

6-Methylmercaptopurine riboside (6MMPR) has been used as a phosphoribosyl pyrophosphate amidotransferase inhibitor to study its effects on DNA replication in a retinoblastoma (Rb) phosphorylation-independent manner in human cytomegalovirus (HCMV) , as a purine analog to determine its effects on angiogenesis of endothelial cells induced by fibroblast growth factor 2 (FGF2) in vitro and in vivo, as a metabolite of 6-methylmercaptopurine to determine its levels in human plasma by high-performance liquid chromatography (HPLC) method .
6-Methylmercaptopurine riboside (6MMPr) is used in studies on thiopurine metabolism by enzymes such as inosine-5′-monophosphate dehydrogenase and thiopurine methyltransferase. 6MMPr may also be used to study mechanisms of bovine viral diarrhea virus (BVDV) inhibition.

Biochem/physiol Actions

6-Methylmercaptopurine riboside (6MMPR) is a modified thiopurine nucleoside involved in the inhibition of purine synthesis. It exhibits anti-viral effects against various viruses. 6MMPR is an analog of purine and an inhibitor of nerve growth factor-activated protein kinase N.

The N6-alkyladenosines and 2-methylthio-N6-alkyladenosines are the most common modified adenosine nucleosides and transfer ribonucleic acids (tRNA) are particularly rich in these modified nucleosides. They are present at position 37 of the anticodon arm and the contribution of these hypermodified nucleosides

The prodrugs azathioprine and 6-mercaptopurine, which are well-established anticancer and immunosuppressive agents, are extensively metabolized by activating and inactivating enzymes. Whereas the 6-thioguanine nucleotides (TGN) are currently being considered as major active metabolites, methylthioinosine nucleotides seem to contribute to the

The PA3004 gene of Pseudomonas aeruginosa PAO1 was originally annotated as a 5'-methylthioadenosine phosphorylase (MTAP). However, the PA3004 encoded protein uses 5'-methylthioinosine (MTI) as a preferred substrate and represents the only known example of a specific MTI phosphorylase (MTIP). MTIP
