Phytochemistry & Biodiscovery

To increase the success rate in finding bioactive natural material, we implement computational and biochemometric techniques in pharmacognostic workflows. For instance, we apply pharmacophore modelling and molecular docking for virtual screening of natural product molecular databases, as well as chemometric approaches, e.g. using heterocovariance analyses.

Predicted ligand target interactions are used to provide insights into the molecular mechanism of identified bioactive compounds and to unravel the polypharmacological complexity of botanicals.
