Disease relevance of METHYLTHIOINOSINE

 

High impact information on METHYLTHIOINOSINE

 

Chemical compound and disease context of METHYLTHIOINOSINE

  • Thus, 6-MMPR, which blocks the de novo pathway of purine nucleotide biosynthesis, caused a pronounced decrease in the intracellular pools of GTP in Sarcoma 180 cells; this phenomenon was accompanied by a marked reduction in the incorporation of radiolabelled mannose into cellular glycoproteins and their dolichol-linked oligosaccharide precursors [2].
  • Four sulphur-containing purine nucleoside analogues: 6MP, 6-thioinosine, 6-methylthioinosine and 6-ethylthioinosine, were examined for antiviral activity against some RNA viruses [8].

Gene context of METHYLTHIOINOSINE

  • This study examined thiopurine methyltransferase (TPMT) and the relationship to thioguanine nucleotides (TGN) and methylthioinosine monophosphate (meTIMP) in a large Swedish patient population [16].
  • Metabolites of 6-TG included thio-XMP, thio-GMP, thio-GDP and thio-GTP, while MMPR-MP was the only major metabolite of MMPR, MMPR (25 microM, 4 h) induced a 16-fold increase in P-Rib-PP and 6-MP (25 microM, 4 h) induced a delayed 5.2-fold increase [9].
 

Analytical, diagnostic and therapeutic context of METHYLTHIOINOSINE

  • An isocratic reversed-phase high-performance liquid chromatographic (HPLC) method for the determination of methylmercaptopurine riboside (MMPR) in human plasma and urine is reported [17].
