This paper examines the formation and stability of nano-complexes that could provide a new therapeutic approach against HIV-1 infection. Poly(propylene imine) glycodendrimers decorated with 2nd generation cationic carbosilane dendrons were generated and their use in polyplex formation checked. Owing to their positively-charged terminal amino groups the hybrid glycodendrimers can bind anionic peptides. It was shown that they form nano-complexes with the HIV-derived peptides P24, Gp160 and Nef. Complexes 130-190 nm in size were formed in molar ratios (dendrimer/ peptide) of (3-4):1. These were sufficiently stable over time and at different pHs. The results obtained suggest that the hybrid dendrimers studied can be considered as alternative carriers for delivering HIV peptides to dendritic cells.

Keywords: PPI-glycodendrimer, HIV-peptide carrier, complex formation, stability of dendriplexes.
