 AB    Various synthetic ribonucleic acids were evaluated for inhibition of
       HIV-induced cytopathicity of cultured cells; only poly and oligoguanylic
       acids, but not other homopolymers, showed potent inhibitory activity.
       Phosphorylation of either the 5'- or 3'-end of oligoribonucleotides
       converted short inactive oligomers, such as dimers to effective anti-HIV
       agents. The efficacy of the 3'-phosphorylated phosphorothioate trimer of
       guanylic acid was comparable to that of other longer oligonucleotides so
       far reported. Phosphorothioate oligoriboguanylic acids were superior to
       the corresponding oligodeoxyguanylic acids in their capacity to prevent
       HIV cytopathicity.
