Synthesis and Biophysical Characterization of G-Rich Oligonucleotides Conjugated with Sugar-Phosphate Tails

A number of 5′-and 3′-glycoconjugates of the oligonucleotide 5′d(TGGGAG)3′ have been synthesized, exploiting fully automated, online phosphoramidite-based solid phase strategy, as potential anti-HIV-1 agents. The thermodynamic stability of the resulting quadruplexes has been investigated by thermal denaturation studies, via a detailed CD Q1 analysis.
