Computation

Docking

 

Computational docking is a core method of structure-based drug design, used to predict the binding mode of a ligand to a target protein. We have recently analyzed the performance of docking methods in the context of fragment-based screening. Specific challenges also arise with covalent ligands. The power of docking analyses in providing explanatory models is highlighted by a study where sequence of protein-protein- and protein-ligand-docking allowed to interpret the mode of action of PROTACs on the Aurora-A-kinase.

Scoring functions

 

Scoring functions are used in docking and virtual screening to assess the quality of binding modes, to rank different ligands and to estimate binding affinities. We have worked in the past on empirical scoring functions and have developed one of the first machine-learning based scoring functions, called SFCscoreRF.

Virtual screening

 

Virtual screening is a computational workflow to identify biocactive molecules with a desired property profile from large compound libraries. Many different approaches and techniques are used for this purpose, as presented in a book edited by us some years ago. An example of how to screen for selective inhibitors of a particular target is illustrated by a study on N-myristoyltransferases, in which we collaborated with the Brenk lab at the University of Bergen.

Molecular dynamics simulations

 

MD simulations are essential to capture the effects of protein flexibility and solvation in structure-based drug design. Two recent studies in which we applied MD simulations for rationalizing experimental inhibition data are listed below. A further field of application are polymers, as illustrated by a review on simulations for polymer bioconjugation. Polymer MD studies from our group can be found in the full publication list.
