  Transition state analogue inhibitors of protozoan nucleoside hydrolases

  摘要：

  Protozoan parasites are unable to synthesize purines de novo and must rely on purine salvage pathways for their requirements. Nucleoside hydrolases, which are not found in mammals, function as key enzymes in purine salvage in protozoa. Inhibition of these enzymes may disrupt purine supply and specific inhibitors are potential therapeutic agents for the control of protozoan infections. A series of 1,4-dideoxy-1,4-imino-D-ribitols bearing C-bonded aromatic substituents at C-1 have been synthesized, following carbanion additions to the imine 2, and tested as potential nucleoside hydrolase inhibitors. Nucleoside analogues 8, 11, 14, 17, 20, 24-26, 28 exhibit K-i values in the range 0.2-22 mu M against two representative isozymes of protozoan nucleoside hydrolases. (C) 1999 Elsevier Science Ltd.
