Abstract
9-(5',5'-Difluoro-5'-phosphonopentyl)-9-deazaguanine (DFPP-DG) and its related analogues were designed as multi-substrate analogue inhibitors of purine nucleoside phosphorylase (PNP) on the basis of the X-ray crystallographic data obtained for the binary complex of 9-(5',5'-difluoro-5'-phosphonopentyl)guanine (DFPP-G) with calf spleen PNP. One of these analogues, homo-DFPP-DG was found to be a very potent PNP inhibitor at an intracellular (approximately 1 mM) phosphate concentration.
