title: Effect of the extent of thiolation and introduction of phosphorothioate internucleotide linkages on the anti-HIV activity of Suligovir [(s4dU)35].
abstract: Suligovir is a 35-mer homo-oligonucleotide, containing exclusively 4-thio deoxyuridylate, proved to be a potent inhibitor of HIV entry. In this paper, we described the effect of extent of thiolation and the introduction of nuclease-resistant phosphorothioate linkages on the anti-HIV activity of Suligovir. We found that the decreased thiolated nucleotide content decreases the anti-HIV potency of the compound and the introduction of phosphorothioate linkages does not improve its antiviral activity.
