NUCLEIC ACIDS CHEMISTRY
Group Leader: Ramon Eritja
The synthesis of nucleic acids (DNA and RNA) is in constant evolution providing a wide range of versatile tools with applications in therapeutics, and material science. Our studies are aimed at gaining a better understanding of novel nucleic acids by chemical modification with the objective of evaluating their efficacy in antisense and RNA interference therapies. The projects undertaken by the group deals with the structural properties of nucleic acids in particular with the introduction of modified nucleotides or conjugates. In addition, we have undertaken the synthesis of new transfecting agents based on cationic lipids for the improvement of nucleic acids delivery. Finally, we develop nucleic acid molecules designed for the assembly of nanomaterials and biosensor systems for detecting biologically relevant DNA and RNA molecules.
Non-canonical structures and nucleic acids conjugates
- Triplex: chemical modifications and structural stability studies
- G-Quadruplex: chemical modifications in loops and tetrads, new architectures, design of specific ligands of biologically relevance sequences
- i-Motif: physico-chemical characterization, design of specific ligands of biologically relevance sequences, quantitative evaluation of duplex/i-motif formation
- Nucleic acids conjugates: lipids, carbohydrates, intercalating agents, peptides/PNA, dyes, polymers
- Oligonucleotides with non-natural nucleosides with structural and biological relevance
Therapeutic oligonucleotides
- small interfering RNA, siRNA: improve stability, gene silencing efficacy and selectivity (reduce off-target effects); structural characterization of siRNA-protein interaction; delivery systems
- Antisense DNA: modulate nuclease stability; delivery systems using new transfecting agents
- microRNA: miRNA mimetics and inhibitors (antagomirs)
- Aptamers: enhance lifetime stability; cytotoxic drug carriers
DNA nanotechnology (biomedical and bio-sensing applications)
- DNA-template assembly of nanoscale architectures (rectangle DNA origami, DNA tetrahedron)
- DNA nanoscaffolds: Biosensors for DNA repair and thrombin detection; delivery systems for cytotoxic drugs, lithography templates for patterning gold surfaces
- DNA-based probes for miRNA and DNA methylation detection
