2.Present methods for exploring the Conformational Space of potential bioactive molecules.
3.Apply methods for exploring the Conformational Space of potential bioactive molecules.
4.Apply Energy Minimization Methods for exploring the Potential Energy Surface.
5.Present and apply principles of Rational Drug Design based on Receptor-Ligand interactions and using NMR constraints.
6.Apply, based on SAR studies, the appropriate functional groups for modification of Peptides to Peptidomimetics.

Competences

At the end of the course the student will have further developed the following skills/competences

1.Ability to demonstrate knowledge and understanding of essential facts, concepts, principles and theories related to 2D NMR, 1Η-1Η /13C/15Ν, and Molecular Modeling and to perform assignment of signal resonances in 2D NMR spectra.
2.Ability to apply such knowledge and understanding to the solution of Spectroscopy and Rational Design issues.
3.Ability to adopt and apply different methodologies on Molecular Modelling techniques.
4.NMR and Molecular Modeling skills needed for continuing professional development.
5.Ability to interact with others on inter or multidisciplinary NMR and Molecular modeling problems.
