Selective diphosphorylation, dithiodiphosphorylation, triphosphorylation, and trithiotriphosphorylation of unprotected carbohydrates and nucleosides

(Chemical Equation Presented) Aminomethyl polystyrene resin-bound linkers of p-acetoxybenzyl alcohol were subjected to reactions with diphosphitylating and triphosphitylating reagents to yield the corresponding polymer-bound diphosphitylating and triphosphitylating reagents, respectively. A number of unprotected carbohydrates and nucleosides were reacted with the polymer-bound reagents. Oxidation with tert-butyl hydroperoxide or sulfurization with Beaucage's reagent, followed by removal of cyanoethoxy group with DBU and the acidic cleavage, respectively, afforded only one type of monosubstituted nucleoside and carbohydrate diphosphates, dithiodiphosphates, triphosphates, and trithiotriphosphates with high regioselectivity.

Synthetic method of nucleoside tetraphosphate

The invention discloses a synthetic method of nucleoside tetraphosphate. The synthetic method comprises the steps of carrying out selective phosphorylation reaction by virtue of nucleoside and a cyclic phosphorylation reagent, and carrying out oxidation and hydrolysis loop opening, so as to obtain nucleoside tetraphosphate. The structure of the cyclic phosphorylation reagent is represented by a formula I (shown in the description). According to the synthetic method, 5'-nucleoside tetraphosphate is selectively generated from nucleoside under the effect of the high-selectivity phosphorylation reagent, and 3'-OH (and 2'-OH) does not need to be protected in the process, namely that the generaiton of 3'(and 2'-)tetraphosphate can be effectively inhibited. Nucleoside tetraphosphate synthesized by virtue of the method has wide use ranges in the biology fields of DNA sequencing, labeling, extension and the like; currently, the selling prices is expensive, a synthetic method is complex, the reaction selectivity is poor; and the synthetic method provided by the invention is good in selectivity and easy in separation and purification, required experimental conditions are simple, and the synthetic processes are all conventional chemical reactions, so that the synthetic method is applicable to large-scale popularization and use.

An improved protection-free one-pot chemical synthesis of 2′-deoxynucleoside-5′-triphosphates

□ A facile, straightforward, reliable, and an efficient method for the gram-scale chemical synthesis of both purine deoxynucleotides such as 2 ′-deoxyguanosine-5 ′-triphosphate (dGTP) and 2 ′- deoxyadenosine-5′-triphosphate (dATP) and pyrimidine deoxynucleotides such as 2 ′-deoxycytidine- 5 ′-triphosphate (dCTP), thymidine-5 ′-triphosphate (TTP), and 2 ′-deoxyuridine-5 ′-triphosphate (dUTP) starting from the corresponding nucleoside is described. This improved "one-pot, three step"Ludwig synthetic strategy involves the monophosphorylation of nucleoside followed by reaction with tributylammonium pyrophosphate and hydrolysis of the resulting cyclic intermediate to provide the corresponding dNTP in good yields (65%-70%).

Substrate specificity of T5 bacteriophage deoxyribonucleoside monophosphate kinase and its application for the synthesis of [α-32P]d/rNTP

Bacteriophage T5 deoxynucleoside monophosphate kinase (dNMP kinase, EC 2.7.4.13) is shown to catalyze the phosphorylation of both d2CMP and ribonucleotides AMP, GMP, and CMP, but does not phosphorylate UMP. For natural acceptors of the phosphoryl group, k m and k cat were found. The applicability of T5 dNMP kinase as a universal enzyme capable of the phosphorylation of labelled r/dNMP was shown for the synthesis of [α- 32P]rNTP and [α-32P]dNTP.

A novel method for the preparation of nucleoside triphosphates from activated nucleoside phosphoramidates

A novel method for the preparation of nucleoside triphosphates has been developed. The strategy employs a highly reactive pyrrolidinium phosphoramidate zwitterion intermediate that undergoes efficient coupling with tris(tetra-n-butylammonium) hydrogen pyrophosphate to generate nucleoside triphosphate.

DNA sequencing by mass spectrometry via exonuclease degradation

Methods for determining the sequence of nucleic acids by cleaving the nucleic acid unilaterally from a first end with an exonuclease activity to sequentially release individual nucleotides, identifying each of the sequentially release nucleotides by mass spectrometry, and determining the sequence of the nucleic acid from the identified nucleotides are disclosed. The method is amenable to multiplexing for simulataneously determining more than one nuleic acid sequence.
