Research lines

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, and specially dendrimers, become chemical tools with great potential in areas as chemical biology and nanomedicine, such as drug delivery, diagnosis and biomaterials. Our group develop and explore the use of diverse types of chemical multivalent platforms (oligomers, dendrimers, polymers, micelles and lipid nanovesicles), being focused on dendrimers.

  1. Design and synthesis of biocompatible DPTA-OEG based dendrimers and study their application study of their application on biomaterial functionalization, as gene-delivery systems, as imaging agents (MRI and fluorescence), among others.

  2. Bivalent and multivalent ligand based on dendrimer platforms as pharmacological and therapeutic tools for the study of GPCR oligomerization, specifically A2AR, D2R, A1R and D1R oligomerization. Application to the development of a novel treatment for movement disorders, as Parkinson’s syndrome, spinal cord injury and restless legs syndrome

  3. Targeted and non-targeted drug-delivery systems for mono and combination therapy for the treatment of advanced colorectal cancer and triple negative breast cancer. These systems are based on multivalent platforms, being some of them hybrids drug-dendrimer platform and micelles composed by these hybrids.
