potential inhibitors of the intermediate stages in the pathway for de novo biosynthesis of purine nucleotides. An intermediate in the preparation of 6 could be cyclized to give 9, a novel analogue of adenosine and inosine, and a potential inhibitor of enzymes which effect reactions at C-6 of purine nucleosides or nucleotides.
