Microwaves - A powerful tool for the base protection of cytidine
Nahar, Pradip
, p. 7253 - 7254 (1997)
Use of microwaves for the base protection of cytidine is described. The procedure gives N-acylcytidine in nearly quantitative yield in 40-60 seconds.
A Chemical Strategy for Intracellular Arming of an Endogenous Broad-Spectrum Antiviral Nucleotide
Antczak, Nicole M.,Arnold, Jamie J.,Caldwell, Haley S.,Cameron, Craig E.,Ciota, Alexander T.,Harki, Daniel A.,Jose, Joyce,Narayanan, Anoop,Ngo, Kiet A.,Passow, Kellan T.,Sturla, Shana J.
, p. 15429 - 15439 (2021/11/12)
The naturally occurring nucleotide 3′-deoxy-3′,4′-didehydro-cytidine-5′-triphosphate (ddhCTP) was recently found to exert potent and broad-spectrum antiviral activity. However, nucleoside 5′-triphosphates in general are not cell-permeable, which precludes
Synthesis method for azvudine
-
Paragraph 0079-0081, (2020/11/22)
The invention discloses a synthesis method for azvudine. The method comprises the following steps of carrying out a hydroxyl substitution reaction on a compound 4 and an iodine elementary substance toobtain a compound 5, carrying out an elimination reaction on an iodo group in the compound 5 to obtain a compound 6, reacting the compound 6 with azide under the catalysis of ICl to obtain a compound7, carrying out an iodine substitution reaction on the compound 7 and carboxylic acid to obtain a compound 8, and carrying out an amino and hydroxyl deprotection reaction on the compound 8 to obtaina compound 9, namely the alzvudine. Compared with an existing synthesis method, the synthesis method has the advantages of short synthesis route, shortened reaction time, mild reaction conditions andeasily controlled reaction process, can be used for preparing the alzvudine with the lower cost, and has a very good application prospect.

Design and development of nucleoside analogs is an established strategy in the antiviral drug discovery field. Nevertheless, for many viruses the coverage of structure-activity relationships (SAR) in the nucleoside chemical space is not sufficient. Here we present the nucleoside SAR exploration for tick-borne encephalitis virus (TBEV), a member of Flavivirus genus. Promising antiviral activity may be achieved by introduction of large hydrophobic substituents in the position 6 of adenosine or bulky silyl groups to the position 5′. Introduction of methyls to the ribose moiety does not lead to inhibition of TBEV reproduction. Possible mechanisms of action of these nucleosides include the inhibition of viral entry or interaction with TBEV non-structural protein 5 methyltransferase or RNA-dependent RNA polymerase domains.

The aqueous N-phosphorylation and N-thiophosphorylation of aminonucleosides
Conway, Louis P.,Delley, Richard J.,Neville, Jonathan,Freeman, Gemma R.,Maple, Hannah J.,Chan, Vincent,Hall, Alexander J.,Hodgson, David R. W.
, p. 38663 - 38671 (2014/11/07)
We demonstrate N-phosphorylation and N-thiophosphorylation of unprotected aminonucleosides in aqueous media. N-Phosphorylations using phosphoric chloride and N-thiophosphorylations using thiophosphoryl chloride were explored as functions of pH using 5′-amino-5′-deoxyguanosine as substrate. These reagents were compared to phosphodichloridate and thiophosphodichloridate ions, and the methodology was applied to other aminonucleosides. S-Alkylations of the nucleoside N-thiophosphoramidates were investigated as functions of pH and alkylating agent. the Partner Organisations 2014.
