NECTAR for strong and/or multifunctional ligands, macromolecules, polyelectrolytes

Strong binding of metal ions (sequestration) and selectivity of binding are processes of outmost importance for several applications (e.g., chelation therapy, nuclear medicine, environmental remediation, metal recovery, water treatment). Strong binding can be operated by a large number of ligands (natural or synthetic) which all share the property of forming very stable complexes. The determination of corresponding thermodynamic equilibrium data is extremely difficult, and cannot be performed by classical approaches. In addition, complexes of some pre-organised ligands (e.g. those currently used in medicine) are formed very slowly, and kinetical aspects have to be considered to get correct thermodynamic data. Also, similar ligands which have limited structural differences often form complexes with the same metal ion that differ in stability by orders of magnitude. Therefore, the design of selective ligands requires a precise knowledge of structure-stability relationships.

Leaders

Tasks

Defining recommended experimental procedures and guidelines for the accurate determination of stability constants and other thermodynamic parameters for systems involving natural and synthetic strong chelators, macromolecules, and polyelectrolytes.
Exploring rational or combinatorial strategies, supported by in silico studies, for the design of new ligands for the selective recognition of metal ions or small molecules in solution.

Activities

Evaluation of the sequestering ability and selectivity of existing and new chelating agents that are of current interest for the scientific community or for the stakeholders (e.g., metallophores, new generation, complexones, etc.).
Study of the speciation of systems containing structurally complex (macro)molecules (e.g., nucleic acids, peptides and proteins, organic matter, polyelectrolytes).
Cross-evaluation of methods for the study of the thermodynamic selectivity.
Setup of protocols and guidelines for the study of these systems and the determination of their thermodynamic parameters.
Formulation of user-friendly strategies for data analysis, and their dissemination.
