Computational Biophysics

Using docking and molecular dynamics to design drugs

We have discovered by high-throughput fragment-based docking several novel chemotypes of potent (single-digit nanomolar) and selective tyrosine kinase inhibitors [1-4].  Explicit solvent molecular dynamics has played an important role for the in silico validation of binding modes and  the selection of compounds for testing in vitro.  Definitive validation of the binding mode has been obtained by X-ray crystallography in our group [1,2].  The most advanced of our tyrosine kinase inhibitors are active on a subset of the NCI 60 cancer cell lines.  Furthermore, some of our  inhibitors have shown good pharmacokinetic properties in mice (including oral bioavailability) and are being currently selected for testing in tumor xenograft models.

Evolutionary Genomics

How orphan genes, novel domains and protein modularity help set the stage for genomic novelties and developmental shifts

Over the past years it became clear that many "novel" genes are indeed truly novel since they have not arisen in the wake of gene or whole genome duplications.

I will discuss the mechanisms of novel gene emergence across different taxa. I will also concentrate on the role which gene rearrangements play for the emergence of novel proteins with altered functions that may cause functional shifts and trigger developmental innovations.

Most shockingly, thousands of domain are completely lost along every lineage over several millions of years but only some tens of domains are newly formed. However, these novel domains seem to have a high adaptive value as they rapidly multiply in genomes and seem to confer a high fitness gains since they are mostly related to biotic and abiotic stress responses.
