Abstract
9-(5',5'-Difluoro-5'-phosphonopentyl)-9-deazaguanine (DFPP-DG) was designed as a multi-substrate analogue inhibitor against purine nucleoside phosphorylase (PNP) on the basis of X-ray crystallographic data obtained for a binary complex of 9-(5',5'-difluoro-5'-phosphonopentyl)guanine (DFPP-G) with calf-spleen PNP. DFPP-DG and its analogous compounds were synthesized by the Sonogashira coupling reaction between a 9-deaza-9-iodoguanine derivative and omega-alkynyldifluoromethylene phosphonates as a key reaction. The experimental details focused on the synthetic chemistry along with some insights into the physical and biological properties of newly synthesized DFPP-DG derivatives are disclosed.

Abstract
9-(5',5'-difluoro-5'-phosphonopentyl)-9-deazaguanine (DFPP-DG) was designed as a multi-substrate analogue inhibitor against purine nucleoside phosphorylase (PNP) on the basis of X-ray crystallographic data obtained for a binary complex of 9-(5',5'-difluoro-5'-phosphonopentyl)guanine (DFPP-G) with calf spleen PNP. DFPP-DG and its analogous compounds were adjusted by length of the linker achieved by the Sonogashira-coupling reaction between a 9-deaza-9-iodoguanine derivative and omega-alkynyldifluoromethylene phosphonates as a key reaction. DFPP-DG is a very potent PNP inhibitor with apparent inhibition constants (in the presence of 1 mM phosphate) of 4.4 and 8.1 nM versus calf spleen and human erythrocyte PNPs, respectively. One of its analogues, homo-DFPP-DG, with longer chain linking phosphonate and 9-deazaguanine is even more potent versus human enzyme, with an apparent inhibition constant of 5.3 nM (in the presence of 1mM phosphate).

Abstract
9-(5',5'-Difluoro-5'-phosphonopentyl)guanine (DFPP-G) and its hypoxanthine analogue (DFPP-H) were modified by introducing a methyl group to all possible positions of the linker connecting a purine and difluoromethylenephosphonic acid moiety to evaluate the effects of the methyl group on inhibition against purine nucleoside phosphorylase. The methyl group on the linker affected the inhibition in a positional-dependent manner. Inhibitory potency of alpha-methyl and beta-methyl-substituted analogues of DFPP-H increased by about 600- to 1000-fold upon converting to cyclopropane nucleotide analogue (+/-)-4.

Abstract
The 1'alpha-phenylselenouridine derivative 13 was successfully synthesized by enolization of the 3',5'-O-TIPDS-2'-ketouridine 8, and was subjected to a radical reaction with a vinylsilyl tether--an efficient procedure for preparing 1'alpha-branched-chain sugar pyrimidine nucleosides. Successive treatment of 8 with LiHMDS and PhSeCl in THF at < -70 degrees C gave the desired 1'-phenylseleno products in 85% yield as an anomeric mixture of the 1'alpha-product 11 and the 1'beta-product 12 (11/12= 2.5:1). Highly stereoselective reduction at the 2'-carbonyl of the 1'alpha-product 11 occurred from the beta-face by using NaBH4/CeCl3 in MeOH, and subsequent introduction of a dimethylvinylsilyl tether at the 2'-hydroxyl gave the radical reaction substrate 14. The photochemical radical atom-transfer reaction of 14 by using a high-pressure mercury lamp proceeded effectively in benzene to give the exo-cyclized PhSe-transferred product 18, in which (PhSe)2 proved to be essential as an additive for radical atom-transfer cyclization reactions. Subsequent phenylseleno-group elimination of 18 gave the sugar-protected 1'alpha-vinyluridine. With this procedure, 1'alpha-vinyluridine (22) and -cytidine (25), designed to be potential antitumor agents, were successfully synthesized. This study is the first example of functionalization at the anomeric 1'-position of a nucleoside by starting from a natural nucleoside to produce a ribo-type 1'-modified nucleoside.

Abstract
1,1-Difluoro-2-(tetrahydro-3-furanyl)ethylphosphonic acids (+/-)-cis-4a and (+/-)-trans-4a possessing a (purine-9-yl)methyl functionality at the ring as well as their homologues (+/-)-cis-4b and (+/-)-trans-4b were synthesized and tested as 'multi-substrate analogue' inhibitors for purine nucleoside phosphorylases. Radical cyclization of allylic alpha,alpha-difluorophosphonates 8a,b was applied to construct the alpha,alpha-difluorophosphonate-functionalized oxacycles 9a,b. The IC50 values of the nucleotide analogues (+/-)-cis-4a and (+/-)-cis-4b were 88 and 38 nM, respectively, for human erythrocyte PNP-catalyzed phosphorylation of inosine in the presence of 100mM orthophosphate. The stereochemistry of the inhibitors was found to affect significantly the inhibitory potency. The transisomers (+/-)-trans-4a and (+/-)-trans-4b were ca. 4-fold less potent than the corresponding cis-isomers. At an intracellular concentration of orthophosphate (1 mM), (+/-)-cis-4b, the most potent compound of this series, was shown to have IC50 and Ki values of 8.7 and 3.5 nM, respectively.
