Abstract
RNA molecules can show high levels of cooperativity in their global folding and interactions with divalent ions. However, cooperativity at individual ligand-RNA interaction sites remains poorly understood. Here, we investigated the binding of thiamine and methylene diphosphonic acid (MDP, a soluble structural analogue of pyrophosphate) to the thiamine pyrophosphate riboswitch. These ligands each bind weakly at proximal subsites, with 10 μM and 1 mM affinities, respectively. The affinity of MDP moderately improves when thiamine or thiamine-like fragments are pre-bound to the RNA. Covalent linking of thiamine and MDP substantially increases riboswitch binding to a notable high affinity of 20 nM. Crystal structures and single-molecule correlated chemical probing revealed favorable induced fit effects upon binding of individual ligands and, unexpectedly, a substantial thermodynamically unfavorable RNA structural rearrangement upon binding of the linked thiamine-MDP ligand. Thus, linking of two ligands of modest affinity, accompanied by an unfavorable structural rearrangement, still yields a potent linked RNA-binding compound. Since complex ligands often bind riboswitches and other RNAs at proximal subsites, principles derived from this work inform and support fragment-linking strategies for identifying small molecules that interact with RNA specifically and with high affinity.

Abstract
Functionalized gem-bisphosphonic acid derivatives being pyrophosphate isosteres are of great synthetic and biological interest since they are currently the most important class of drugs developed for the treatment of diseases associated with the disorder of calcium metabolism, including osteoporosis, Paget’s disease, and hypercalcemia. In this article, we will try to give an in-depth overview of the methods for obtaining α- heteroatom-substituted methylenebisphosphonates and acquaint the reader with the synthetic strategies that are used to develop biologically important compounds of this type.

Abstract
Cytidine-5'-triphosphate synthase (CTPS) catalyzes the formation of cytidine triphosphate (CTP) from glutamine, uridine 5'-triphosphate (UTP), and adenosine 5'-triphosphate (ATP). This reaction proceeds via formation of the high-energy intermediate UTP-4-phosphate (UTP-4-P). Stable analogues of UTP-4-P may be potent inhibitors of CTPS and useful as lead structures for the development of anticancer and antiviral agents. Several bismethylene triphosphate (BMT) nucleotides of uridine 4-phosphate (U-4-P) analogues have been prepared. A key step was the selective methanolysis, with the aid of a tin catalyst, of the 5' ester moiety of 2',3',5'-tri-O-acetyl or tri-O-benzoyl U-4-P analogues. We believe this represents the first general approach to the selective cleavage of 5' benzoyl esters in benzoylated nucleosides. Mitsunobu coupling of these 5'-deprotected U-4-P analogues to an unsymmetrical, protected BMT bearing a free phosphonic acid moiety at one of the terminal positions gave fully protected BMT-U-4-P analogues. Global deprotection of these species was achieved using TMSBr followed by treatment with NH4OH-MeOH or NH4OH-pyridine. The resulting BMT nucleotides represent a new class of anionic pyrimidine nucleotide analogues.

Abstract
A protected, unsymmetrical bismethylene triphosphate analogue was prepared by sequential Michaelis-Arbuzov reactions on ethyl bis(halomethyl)phosphinates. This species was monodeprotected at one of the terminal phosphonate groups in high yield. The resulting monodeprotected compound was used to achieve the first syntheses of the bismethylene triphosphate analogues of UTP and CTP.

Abstract
Thiamine triphosphate (ThTP) is found in most living organisms and it may act as a phosphate donor for protein phosphorylation. We have recently cloned the cDNA coding for a highly specific mammalian 25 kDa thiamine triphosphatase (ThTPase; EC 3.6.1.28). As the enzyme has a high catalytic efficiency and no sequence homology with known phosphohydrolases, it was worth investigating its structure and catalytic properties. For this purpose, we expressed the untagged recombinant human ThTPase (hThTPase) in E. coli, produced the protein on a large scale and purified it to homogeneity. Its kinetic properties were similar to those of the genuine human enzyme, indicating that the recombinant hThTPase is completely functional. Mg2+ ions were required for activity and Ca2+ inhibited the enzyme by competition with Mg2+. With ATP as substrate, the catalytic efficiency was 10(-4)-fold lower than with ThTP, confirming the nearly absolute specificity of the 25 kDa ThTPase for ThTP. The activity was maximum at pH 8.5 and very low at pH 6.0. Zn2+ ions were inhibitory at micromolar concentrations at pH 8.0 but activated at pH 6.0. Kinetic analysis suggests an activator site for Mg2+ and a separate regulatory site for Zn2+. The effects of group-specific reagents such as Woodward's reagent K and diethylpyrocarbonate suggest that at least one carboxyl group in the active site is essential for catalysis, while a positively charged amino group may be involved in substrate binding. The secondary structure of the enzyme, as determined by Fourier-transform infrared spectroscopy, was predominantly beta-sheet and alpha-helix.
