| | 5'-DEOXY-5'-METHYLTHIOADENOSINE Usage And Synthesis |
| Uses | 5′-Deoxy-5′-(methylthio)adenosine has been used as a protein methylation inhibitor to reduce E2F transcription factor 1 (E2F1) protein abundance in hepatocellular carcinoma (HCC) cells. It has also been used to inhibit histone methylation modification and study its role in hypoxia inducible factor-1 (Hif-1) nuclear transport. | | Definition | ChEBI: Adenosine with the hydroxy group at C-5' substituted with a methylthio (methylsulfanyl) group. | | Biological Activity | ki = 62 μm for s49-derived high-affinity camp phosphodiesterasemethylthioadenosine (mta) is a naturally occurring sulfur-containing nucleoside in all mammalian tissues. mta is mainly produced from s-adenosylmethionine via the polyamine biosynthetic pathway, behaving as a powerful inhibitory product. | | Biochem/physiol Actions | 5′-Deoxy-5′-(methylthio)adenosine (Methylthioadenosine) may be used as a substrate to study the specificity and kinetics of 5′-methylthioadenosinephosphorylase (MTAP) (EC2.4.2.28), a tumor suppressor gene expressed enzyme that supports the S-adenosylmethionine (AdoMet) and methionine salvage pathways. | | in vitro | mta was found to be solely metabolized by mta-phosphorylase, to yield 5-methylthioribose-1-phosphate and adenine, which was a key step in methionine and purine salvage pathways, respectively. previous studies suggested that mta coud affect various cellular processes. mta had been shown to be albe to influence plenty of critical cell responses, such as proliferation, gene expression regulation, differentiation as well as apoptosis. though most of such responses had been only observed at the pharmacological level, their specificity made it tempting to speculate that endogenous mta might play a regulatory role in the cell [1]. | | in vivo | the hepatoprotective effects of mta had been evaluated in a model of ccl4-induced chronic liver damage in rats. in this study, mta could reproduce the human lesions induced by alcohol and viral infections of the liver. in addition, replenishment of the hepatic pool of mta showed strong anti-oxidant effects and also reduced liver cell damage and fibrosis [2]. | | Purification Methods | Recrystallise it from H2O and sublime it at 200o/0.004mm.
