1-Deazaadenosine is a potent Adenosine deaminase inhibitor (Ki: 0.66 μM). It exhibits anti-cancer activities in vitro and has the potential to be a chemotherapy agent for lymphoproliferative disorders.
Adenosine deaminase is an enzyme that catalyzes the irreversible deamination of 2'-deoxyadenosine and adenosine to 2'-deoxyinosine and inosine, respectively.
Oxanosine is an analog of guanosine that has been found in S. capreolus and has diverse biological activities, including antibacterial, antiviral, and anticancer properties. It is active against a variety of bacteria, including S. flexneri, P. mirabilis, and E. coli (MICs = 6.25, 12.5, 25 µg/ml, respectively, on peptone, but not nutrient, agar). Oxanosine inhibits replication of the HIV-1 strain IIIb in infected CEM and U937, but not H9, cells (EC50s = 7, 27, and >500 µg/ml, respectively). It also inhibits the growth of HeLa human cervical cancer cells (IC50 = 32 µg/ml) and reduces tumor growth in a murine L1210 lymphocytic leukemia model.
FR-221647 is a non-nucleoside adenosine deaminase inhibitor, it has moderate activity and good pharmacokinetics compared with the known inhibitors EHNA and pentostatin.
