Synthesis of Nucleoside Tetraphosphates and Dinucleoside Pentaphosphates via Activation of Cyclic Trimetaphosphate
摘要:
A procedure for the synthesis of dinucleoside 5'-pentaphosphates (Np5N) and nucleoside 5'-tetraphosphates (Np-4) is described. The procedure relies on the activation of cyclic trimetaphosphate followed by a reaction with a nucleoside 5'-monophosphate (NMP) to give intermediates of type 3. Reaction of 3 with water or an NMP gives the desired products in yields ranging from 77 to 86%.

Phosphoanhydrides (P‐anhydrides) are ubiquitously occurring modifications in nature. Nucleotides and their conjugates, for example, are among the most important building blocks and signaling molecules in cell biology. To study and manipulate their biological functions, a diverse range of analogues have been developed. Phosphate‐modified analogues have been successfully applied to study proteins that

A methodology for the synthesis of oligophosphate conjugates using phosphordiamidites is described. This strategy facilitates the straightforward preparation of C2-symmetric dinucleoside tri-, penta-, and heptaphosphates. Moreover, unsymmetric compounds such as thiamine adenosine triphosphate and thiamine cytidine triphosphate can be prepared. The material is used to study the inhibitory activity of
developed fluorescentlylabelledadenosine tri-, tetra- and pentaphosphate analogues of ATP. The novel ATP analogues bear - in contrast to earlier reports - only a single acridone-based dye at the terminal phosphate group. The dye's fluorescence is quenched by the adenine component of the ATP analogue and is restored upon cleavage of the phosphate chain and dissociation of the dye from the adenosine moiety

for dicarboxylates or phosphates can be switched by using guanidinium- or ammonium-functionalized probes. One of these probes turned out to be selective towards glutamate over aspartate and γ-aminobutyric acid (GABA). Another was selective towards adenosine 5′-triphosphate (ATP) over adenosine 5′-diphosphate (ADP), pyrophosphate (PPi), adenosine 5′-monophosphate (AMP), and orthophosphate (Pi). In both
