RESUMO
TransferRNA's role in protein translation is the prime example of an Informational Leaving Group (ILG). A simplified model produced oligophenylalanine with a modified uracil as an ILG in the presence of specific oligonucleotides. Our preliminary studies contribute to the importance of hybrid species in bridging the gap between peptides and nucleic acids.

A 2-amino-1,8-naphthyridine derivative that is described to bind single guanine bulges in RNA-DNA and RNA-RNA duplexes was synthesized and its interaction with the single G bulge in the conserved CREX of the Hepatitis E Virus (HEV) genome was explored by NMR and molecular modeling. Results indicate that the ligand intercalates in the internal loop, though none of the expected hydrogen bonds with the single G in the bulge could be demonstrated.
