  Adenosine Kinase Inhibitors. 3. Synthesis, SAR, and Antiinflammatory Activity of a Series of l-Lyxofuranosyl Nucleosides

  摘要：

  Chronic inflammatory diseases, such as arthritis and rheumatoid arthritis, remain major health problems worldwide. We previously demonstrated that adenosine kinase inhibitors (AKIs) exhibit antiinflammatory effects by inhibiting TNF-alpha production, neutrophil accumulation, and edema formation. Although adenosine receptor agonists produce similar effects, AKIs showed the antiinflammatory activity without the cardiovascular side effects that prevented the development of adenosine receptor specific agonists. However, previously described potent AKIs, such as 5-iodotubercidin, are nucleosides which have the potential to undergo in vivo 5'-O-phosphorylation and therefore produce cytotoxicity. In an effort to eliminate toxicities produced by phosphorylated nucleosides, L-lyxofuranosyl analogues of tubercidin were tested as potential AKIs since the opposite stereochemical. orientation of the CH2OH was expected to eliminate intracellular phosphorylation. Described herein are the discovery of a new series of AKIs based on alpha-L-lyxofuranosyl. nucleosides, their SAR, as well as the antiinflammatory activity of the lead compound GP790 (IC50 = 0.47 nM, 47% inhibition of paw swelling at 10 mg/kg in rat carrageenan paw edema model). In addition, a study showing that in the skin lesion model the antiinflammatory activity is reversed by an A2 selective adenosine receptor antagonist 3,7-dimethyl-1-propylxanthine (DMPX) is also described.
