  Investigations into the Origin of the Molecular Recognition of Several Adenosine Deaminase Inhibitors

  摘要：

  Inhibitors of adenosine deaminase (ADA, EC 3 5 4 4) are potential therapeutic agents for the treatment of various health disorders Several highly potent inhibitors were previously identified, yet they exhibit unacceptable toxicities We performed a SAR study involving a series of C2 or C8 substituted purine-riboside analogues with a view to discover less potent inhibitors with a lesser toxicity We found that any substitution at C8 position of nebularine resulted in total loss of activity toward calf intestinal ADA However several 2-substituted-adenosine, 8-aza-adenosine, and nebularine analogues exhibited inhibitory activity Specifically, 2-Cl-purine riboside, 8-aza-2-thiohexyl adenosine, 2-thiohexyl adenosine, and 2-MeS-purine riboside were found to be competitive inhibitors of ADA with K-i values of 25, 22, 6, and 3 mu M, respectively We concluded that electronic parameters are not major recognition determinants of ADA but rather steric parameters A C2 substituent which fits ADA hydrophobic pocket and improves H-bonding with the enzyme makes a good inhibitor In addition, a gg rotamer about C4'-C5' bond is apparently an important recognition determinant

  A highly regioselective Minisci reaction with the decarboxylative alkylation of purine nucleosides under mild conditions was developed. With 5 mol % AgNO3 as a catalyst and (NH4)2S2O8 as an oxidant, a series of purine nucleosides including ribosyl, deoxyribosyl, arabinosyl purine nucleosides worked well with primary, secondary, and tertiary aliphatic carboxylic acids.

  A simple dehydrazination reaction has been achieved in the presence of a catalytic amount of CuSO4 for the first time. With CuSO4 (2 mol%) as a catalyst and water as a solvent, the dehydrazination products were obtained in good yields (66–95%). Moreover, the drugs nebularine and vidarabine were afforded successfully, and vidarabine could be produced on a 0.923 kg scale, which shows good potential for industrial applications.
