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.

Methods are described for the synthesis of 15N-labelled guanosines and deoxyguanosines, suitable for incorporation into oligonucleotides.The 15N is located at N-1 (e.g. guanosine 1a and deoxyguanosine 1b> or at the NH2 (e.g. guanosine 1
An Improved Method for the Application of the 4-Methoxybenzyl Group to Protect the 2'-Hydroxyl Group in the Ribonucleotide Synthesis by TFA-acidolysis

The cleavage of the 4-methoxybenzyl group from the 2'-OH-position of ribonucleosides by the hydrogenation with different Pd-catalysts as well as trifluoroacetic acid has been studied in detail.During hydrogenation, side reactions at the base residue of cytidine occurred which, however, could be extensively suppressed by PdCl2 catalysis.More practicable results were obtained with trifluoroacetic acid in the presence of cation scavengers, allowing smoothly to convert a series of 2'-methoxybenzyl ribonucleotides to the homogeneous deprotection products.
