Ligand Identification and Optimisation
Left) Docking of a ligand into the binding site of a receptor target structure provides a model of the mode-of-action, guiding further medicinal chemistry optimisation and pharmacological validation by mutagenesis. Right) Pharmacophore elements are placed based on known ligands to give a 3D representation of the features important for target interaction and activity, and are used to identified new ligands with other chemical structures.
"Today the computer is just as important a tool for chemists as the test tube. Simulations are so realistic that they predict the outcome of traditional experiments.
Finale of the motivation for the
2013 Nobel Prize in Chemistry
Today, computational models are integral for the rationalization of experimental data and generation of hypotheses for new studies. In the Gloriam group, we combine bioinformatics, chemoinformatics and computational chemistry in computational drug design at GPCRs. We also develop new methods for virtual screening, chemogenomics and design of target-directed focused screening libraries.
The work has led to the identification of novel ligands for the chemokine, glutamate, histamine and serotonin receptors. It is highly interdisciplinary, building on collaborations with the Chemistry and Medicinal Chemistry and Molecular Pharmacology groups at the Department of Drug Design and Pharmacology, as well as several international labs.
