MULTIVALENT SYSTEMS FOR NANOMEDICINE
Group Leader: Miriam Royo
Chemical Multivalent Systems are molecules containing multiple functional groups disposed on spatial distributions that are directly associated to their skeleton/scaffold architecture. These functional groups can be modified, in a controlled manner, with diverse biomolecules, drugs or ligands. Due to this versatility, multivalent systems become chemical tools with great potential in areas as chemical biology and nanomedicine, such as drug delivery, diagnosis and biomaterials.
Our group explore the use of diverse types of chemical multivalent platforms (oligomers, dendrimers, polymers, micelles and lipid nanovesicles), in:
-the generation of multivalent ligands to study GPCR oligomerization; and
-the development of drug delivery systems for colorectal and breast cancer treatment, protein delivery systems for the treatment of lysosomal diseases and macromolecular compounds that have intrinsically therapeutic properties with application to central nervous system diseases.
We also explore the use of different targeting moieties (peptides, small molecules) or transporters to improve the accumulation of these delivery systems of therapeutic agents on specific cells, tissue or organs, or to facilitate the entry through biological barriers as blood brain barrier.
- Design and synthesis of biocompatible multivalent systems, as dendrimers, and the study of their applications in biomedicine and chemical biology.
- Bivalent and multivalent ligands as pharmacological tools for the study of GPCR oligomerization, specifically A2AR, D2R, A1R and D1R oligomerization. Explore their application on the development of a novel treatment for movement disorders, as Parkinson’s syndrome, spinal cord injury and restless legs syndrome.
- Targeted and non-targeted drug-delivery systems for mono and combination therapy for the treatment of advanced colorectal cancer and triple negative breast cancer.
- Targeting moiety-cholesterol-PEG hybrids as components of lipid nanoparticles. Application to the development of a protein delivery system for Fabry’s disease.
- Transporter based on peptidomimetics or peptides with the ability to cross biological barriers, as cell membrane and blood brain barrier. Peptide and small molecule ligands as targeting moieties for different applications.
