Synthesis of nucleosides as potential inhibitors of purine biosynthesis.
The synthesis of analogues of 4-carboxy-5-amino-1-beta-D-ribofuranosylimidazole-5'-phosphate (CAIR) in which the carbonyl group is replaced by a grouping of tetrahedral geometry is described. These are planned as transition state inhibitors of SAICAR synthetase, the enzyme which converts CAIR into its amide with L-aspartic acid.
