RESUMO
We report the synthesis of a peptide nucleic acid (PNA) monomer containing preQ1, a positively charged guanine analogue. The new monomer was incorporated into PNA oligomers using standard Fmoc-chemistry-based solid-phase synthesis. The preQ1 unit-containing PNA oligomers exhibited improved affinity for their complementary DNA through electrostatic attraction, and their sequence specificity was not compromised. It could be beneficial to incorporate preQ1 into PNA oligomers instead of guanine when creating antisense/antigene agents or research tools.
