Abstract
Diphosphoinositol phosphates (PP-InsPs) are an evolutionarily ancient group of signalling molecules that are essential to cellular and organismal homeostasis. As the detailed mechanisms of PP-InsP signalling begin to emerge, synthetic analogues of PP-InsPs containing stabilised mimics of the labile diphosphate group can provide valuable investigational tools. We synthesised 5-PCF2Am-InsP5 (1), a novel fluorinated phosphonate analogue of 5-PP-InsP5, and obtained an X-ray crystal structure of 1 in complex with diphosphoinositol pentakisphosphate kinase 2 (PPIP5K2). 5-PCF2Am-InsP5 binds to the kinase domain of PPIP5K2 in a similar orientation to that of the natural substrate 5-PP-InsP5 and the PCF2Am structure can mimic many aspects of the diphosphate group in 5-PP-InsP5. We propose that 1, the structural and electronic properties of which are in some ways complementary to those of existing phosphonoacetate and methylenebisphosphonate analogues of 5-PP-InsP5, may be a useful addition to the expanding array of chemical tools for the investigation of signalling by PP-InsPs. The PCF2Am group may also deserve attention for wider application as a diphosphate mimic.

Abstract
A new method for the synthesis of fluorinated α-C-glycosides is described. The reactions between highly electrophilic radicals (fluorinated or unfluorinated) and a 2-benzyloxyglucal or galactal provide 2-keto-D-arabino- or 2-keto-D-lyxo-hexopyranosides through an addition/fragmentation process. Sodium borohydride mediated or Meerwein-Ponndorf-Verley (MPV) reduction of these compounds provides α-C-glycosides that feature appropriate anchoring groups for further synthetic elaboration. The presence of CF2 CO2 iPr or CF2 Br groups at the pseudo-anomeric position allows efficient reduction/olefination or Br/Li-exchange/nucleophilic-addition sequences. These transformations open the way for the synthesis of fluorinated C-glycosidic analogues of glycoconjugates.

Abstract
Early studies on chemical synthesis of biological molecules can be seen to progress to preparation and biological evaluation of phosphonates as analogues of biological phosphates, with emphasis on their isosteric and isopolar character. Work with such mimics progressed into structural studies with a range of nucleotide-utilising enzymes. The arrival of metal fluorides as analogues of the phosphoryl group, PO(3)(-), for transition state (TS) analysis of enzyme reactions stimulated the symbiotic deployment of (19)F NMR and protein crystallography. Characteristics of enzyme transition state analogues are reviewed for a range of reactions. From the available MF(x) species, trifluoroberyllate gives tetrahedral mimics of ground states (GS) in which phosphate is linked to carboxylate and phosphate oxyanions. Tetrafluoroaluminate is widely employed as a TS mimic, but it necessarily imposes octahedral geometry on the assembled complexes, whereas phosphoryl transfer involves trigonal bipyramidal (tbp) geometry. Trifluoromagnesate (MgF(3)(-)) provides the near-ideal solution, delivering tbp geometry and correct anionic charge. Some of the forty reported tbp structures assigned as having AlF(3)(0) cores have been redefined as trifluoromagnesate complexes. Transition state analogues for a range of kinases, mutases, and phosphatases provide a detailed description of mechanism for phosphoryl group transfer, supporting the concept of charge balance in their TS and of concerted-associative pathways for biocatalysis. Above all, superposition of GS and TS structures reveals that in associative phosphoryl transfer, the phosphorus atom migrates through a triangle of three, near-stationary, equatorial oxygens. The extension of these studies to near attack conformers further illuminates enzyme catalysis of phosphoryl transfer.

Abstract
In drug discovery, different methods exist to create new inhibitors possessing satisfactory biological activity. The multisubstrate adduct inhibitor (MAI) approach is one of these methods, which consists of a covalent combination between analogs of the substrate and the cofactor or of the multiple substrates used by the target enzyme. Adopted as the first line of investigation for many enzymes, this method has brought insights into the enzymatic mechanism, structure, and inhibitory requirements. In this review, the MAI approach, applied to different classes of enzyme, is reported from the point of view of biological activity.

Abstract
This overview focuses on the (alpha,alpha-difluoromethylene)phosphonate mimic of phosphoserine (pCF(2)Ser) and its application to the study of kinase-mediated signal transduction-pathways of great interest to drug development. The most versatile modes of access to these chemical biological tools are discussed, organized by method of PCF(2)-C bond formation. The pCF(2)-Ser mimic may be site-specifically incorporated into peptides (SPPS) and proteins (expressed protein ligation). This isopolar, dianionic pSer mimic results in a "constitutive phosphorylation" phenotype and is seen to support native protein-protein interactions that depend on serine phosphorylation. Signal transduction pathways studied with this chemical biological approach include the regulation of p53 tumor suppressor protein activity and of melatonin production. Given these successes, the future is bright for the use of such "teflon phospho-amino acid mimics" to map kinase-based signaling pathways.

Abstract
The C-1-phosphonate analogue of UDP-GlcNAc has been synthesized using an alpha-configured C-1-aldehyde as a key intermediate. Addition of the anion of diethyl phosphate to the aldehyde produced the hydroxyphosphonate. The configuration of this key intermediate was determined by X-ray crystallography. Deoxygenation, coupling of the resulting phosphonic acid with UMP and deprotection gave the target molecule as a di-sodium salt. This analogue had no detectable activity as an inhibitor of (OGT).

Abstract
A series of hitherto unknown 3,4-epoxy-1,1-difluorobutenes were prepared from the readily accessible alpha,beta-epoxy ketones and these compounds were found to undergo regioselective S(N)2' reactions with hard RLi nucleophiles occurring at the highly positively charged terminal fluorine-possessing sp(2) carbon atom in quite sharp contrast to the cases of the corresponding nonfluorinated vinyloxiranes which only attained a low level of regioselectivity. Addition of HMPA substantially improved the products' olefinic stereoselectivity. Theoretical calculations were used to qualitatively explore the nature of selectivity in these reactions.

Abstract
We have previously reported dissociation constants for a range of bisphosphonate analogs of 1,3-bisphospho-D-glyceric acid binding to yeast phosphoglycerate kinase. Data for the unsymmetrical analogs were difficult to interpret because it was not clear in which of the two possible orientations these ligands bound. Here we report a novel NMR method for quantifying orientation preference based on relaxation effects induced by titration with CrADP, which is applied to these ligands. It is shown that all ligands can bind in both orientations but that the driving force for the orientational preference is to put the alpha,alpha-difluoromethanephosphonate group in the "basic patch" (nontransferable phosphate) position. The relevance to the design of phosphoglycerate kinase inhibitors is discussed.

Stable bisubstrate ligands of phosphoglycerate kinase (PGK) have been synthesized with AMP or ADP conjugated to hydrolytically-stable, symmetrical analogues of 1,3-bisphosphoglycerate and their binding to yeast PGK evaluated. Their Kds decrease with net negative charge, with a penta-anionic analogue 7 showing highest affinity-in accordance with its approximation to the transition state for the reaction catalysed by PGK.

Abstract
Inhibition of the glycolytic enzyme phosphoglycerate kinase (PGK) in erythrocyte cells could provide a method of treatment for cardiovascular and respiratory disorders. The product of the reaction catalysed by PGK, 1,3-diphosphoglycerate, is converted by another enzyme in erythrocytes to 2,3-diphosphoglycerate, which is an allosteric effector of haemoglobin. For this reason, a series of fluoro-phosphonate inhibitors have been tested for their potency in detailed inhibition kinetic experiments with yeast PGK. The results were analysed by Lineweaver-Burk and Dixon plots and Ki values obtained. Two fluorophosphonates were found to be inhibitory and both have an electron rich mid-chain functionality, which is thought to provide electrons for hydrogen bonding to residues in the triose binding site of the enzyme. It is postulated that either the fluorine or mid-chain moieties of the analogues are binding to Asp23 and Asn25 residues in the so called 'basic patch' area of the triose site. These residues are shown to bind to the D-hydroxyl moiety on the C2 of the true substrate, 3-phosphoglycerate, in the high-resolution crystal structure of pig muscle PGK co-crystallized with 3-phosphoglycerate.
