Protein-Ligand Interactions  

In the study of intermolecular interactions involving protein and ligands, we expect to gain further insights into the structural basis for the specificity of small-molecule ligands against a specific protein target (De Azevedo, 2008). Analysis of protein-ligand interaction is a central problem in the drug design. Knowledge of the key features responsible for the specificity of a ligand for a protein allows us to determine which physical-chemical parameters could be changed to improve the protein-ligand interaction (De Azevedo & Dias, 2008a). Furthermore, the development of a computational model to predict the binding affinity based on the atomic coordinates of a protein-ligand complex (De Azevedo & Dias, 2008b) opens the possibility to apply virtual screening approaches to search small-molecule databases to identify a drug candidate (De Azevedo, 2010a). To study protein-ligand interactions, we make use of protein crystallography (Canduri & De Azevedo, 2008), nuclear magnetic resonance spectroscopy (Fadel et al., 2005), molecular docking (De Azevedo, 2010b), and molecular dynamics (De Azevedo, 2011).
