5'-Deoxy-5'-methylthioadenosine phosphorylase (MTAP) is involved in the salvage of adenine and methylthio moieties of 5'-deoxy-5'-methylthioadenosine, a byproduct of polyamine synthesis, to adenine nucleotides and methionine, respectively. The gene encoding MTAP, MTAP, is frequently codeleted along with the tumor suppressor gene

Many fluorinated analogues of adenosine nucleoside have been synthesized and studied as potential antitumor and antiviral agents. Earlier, we reported radiosynthesis of 2'-deoxy-2'-[(18)F]fluoro-1-beta-D-arabinofuranosyl-adenine ([(18)F]-FAA) and 3'-deoxy-3'-[(18)F]fluoro-1-beta-d-xylofuranosyl-adenine ([(18)F]FXA). Now, we report their in vivo studies including blood clearance, biodistribution and micro-PET
Synergistic inhibition of platelet aggregation by forskolin plus PGE1 or 2-fluoroadenosine: effects of 2',5'-dideoxyadenosine and 5'-methylthioadenosine.
In adult schistosomes, the enzyme adenosine kinase (AK) is responsible for the incorporation of some adenosine analogues, such as 2-fluoroadenosine and tubercidin, into the nucleotide pool, but not others. In the present study, the structures of four complexes of Schistosoma
In contrast to several other glutamine amidotransferases including asparagine synthetase, cytidine 5'-triphosphate (CTP) synthetase, carbamoyl phosphate synthetase, and phosphoribosyl pyrophosphate (PRPP) amidotransferase, guanosine monophosphate synthetase (GMPS) will not utilize hydroxylamine as an alternative nitrogen source. Instead, the enzyme is inhibited
