MediNewsDigest: Methylthioadenosine (MTA) shows promise as a possible treatment of MS in this reference from PubMed, (entry jul 29,2010) the National Center for Biotechnology Information/ National Institute of Health (NIH).
Quoting:”… the highest dose of MTA (60 mg/kg) was more efficacious than mouse interferon-beta or Glatiramer acetate [Copaxone,Teva]….Combination therapy assays between MTA and interferon-beta or Glatiramer acetate were more effective than the individual therapies”
Keep in mind that this was a study on animal, probably mice, with experimental autoimmune encephalomyelitis (EAE).
But what is MTA? From this entry in sciencedirect it is a ” naturally occurring sulfur-containing nucleoside present in all mammalian tissues” click on the the the Wiki link to nucleoside for more background.
What is interesting is that MTA also shows promises in melanoma treatment. See this link to biomedcentral (BMC,2010)
Those are recent papers, let us see how the dust settles.
