| Sumario: | © 2015 Wiley-VCH Verlag GmbH & Co. KGaA. Antisense oligodeoxynucleotides (ODNs) are short synthetic DNA polymers complementary to a target RNA sequence. They are commonly designed to halt a biological event, such as translation or splicing. ODNs are potentially useful therapeutic agents for the treatment of different human diseases. Carbohydrate-ODN conjugates have been reported to improve the cell-specific delivery of ODNs through receptor mediated endocytosis. We tested the anti-HIV activity and biochemical properties of the 5′-end glucose-conjugated GEM 91 ODN targeting the initiation codon of the gag gene of HIV-1 RNA in cell-based assays. The conjugation of a glucose residue significantly reduces the immunostimulatory effect without diminishing its potent anti-HIV-1 activity. No significant effects were observed in either ODN stability in serum, in vitro degradation of antisense DNA-RNA hybrids by RNase H, cell toxicity, cellular uptake and ability to interfere with genomic HIV-1 dimerisation. |
