Mi. Anazodo et al., CHARACTERIZATION OF GPI2A, A POTENT INHIBITOR OF HIV-1 GENE-EXPRESSION AND VIRAL REPLICATION, Nucleosides & nucleotides, 16(7-9), 1997, pp. 1241-1249
Fully thioated antisense molecules are often cytotoxic and non-specifi
c in action. GPI2A is thioated at 7 base positions. GPI2A posses seque
nce-specific activity against HIV-1 gene expression and viral replicat
ion without significant cytotoxicity. Partial thioation did not compro
mise its uptake, cellular distribution and nuclease resistance.
