RESUMO

In this work, several ribavirin analogues were synthesized and incorporated into a multivalent arrangement. Both were subsequently modified by the addition of polyhydroxylated residues. Their antiviral activity was tested against Junín virus, etiological agent responsible of Argentine hemorrhagic fever. Some compounds inhibited Junín virus in the range of 13.2-389.1 µM. Two modified ribavirin analogues presented an effective concentration comparable to ribavirin but with a higher selectivity index.
