Abstract
The phosphorothioate oligonucleotide T(2)G(4)T(2) was identified as an inhibitor of HIV infection in vitro by combinatorial screening of a l ibrary of phosphorothioate oligonucleotides that contained all possibl e octanucleotide sequences. The oligonucleotide forms a parallel-stran ded tetrameric guanosine-quartet structure. Tetramer formation and the phosphorothioate backbone are essential for antiviral activity. The t etramer binds to the human immunodeficiency virus envelope protein gp1 20 at the V3 loop and inhibits both cell to-cell and virus-to cell inf ection.
