Adenosinedeaminase is an enzyme that catalyzes the irreversible deamination of 2'-deoxyadenosine and adenosine to 2'-deoxyinosine and inosine, respectively.
1-Deazaadenosine is a potent Adenosinedeaminase inhibitor (Ki: 0.66 μM). It exhibits anti-cancer activities in vitro and has the potential to be a chemotherapy agent for lymphoproliferative disorders.
FR-221647 is a non-nucleoside adenosinedeaminase inhibitor, it has moderate activity and good pharmacokinetics compared with the known inhibitors EHNA and pentostatin.
2'-Deoxyadenosine-5'-triphosphate (dATP) is a purine nucleotide and derivative of the nucleic acid adenosine 5'-triphosphate .1dATP is a substrate for DNA polymerase in the synthesis of DNA.2It is a noncompetitive inhibitor of ribonucleotide reductases, which provides feedback inhibition during DNA synthesis.1dATP has commonly been used in DNA synthesis, sequencing, and labeling in research applications.3,4dATP accumulates in adenosinedeaminase deficiency, a disorder characterized by mutations in the gene for adenosinedeaminase, the enzyme that catalyzes the deamination of adenosine and deoxyadenosine.5 1.Berg, J.M., Tymoczko, J.L., and Stryer, L.Key steps in nucleotide biosynthesis are regulated by feedback inhibitionBiochemistry(2002) 2.Berg, J.M., Tymoczko, J.L., and Stryer, L.DNA is replicated by polymerases that take instructions from templatesBiochemistry(2002) 3.Cadwell, R.C., and Joyce, G.F.Randomization of genes by PCR mutagenesisPCR Methods Appl.2(1)28-33(1992) 4.Steffens, D.L., Jang, G.Y., Sutter, S.L., et al.An infrared fluorescent dATP for labeling DNAGenome Res.5(4)393-399(1995) 5.Flinn, A.M., and Gennery, A.R.Adenosinedeaminase deficiency: A reviewOrphanet J.

2′-O-(2-Methoxyethyl)guanosine (2'-O-MOE-rG), a modified nucleoside, can be enzymatically converted from 2′-O-(2-methoxyethyl)-2,6-diaminopurine riboside by adenosinedeaminase. However, this compound is not readily phosphorylated by cytosolic nucleoside kinases, and it cannot be incorporated into cellular DNA or RNA.
