Protein target prediction of a bioactive ligand with Align-it and ePharmaLib

Bioactive compounds often bind to several target proteins, thereby exhibiting polypharmacology. Experimentally determining these interactions is however laborious, and structure-based virtual screening of bioactive compounds could expedite drug discovery by prioritizing hits for experimental validation.

The Pharmaceutical Bioinformatics group at the University of Freiburg has therefore developed Zauberkugel, a workflow for pharmacophore-based protein target prediction of a bioactive ligand with the tool Align-it and the recently reported pharmacophore dataset ePharmaLib. The Zauberkugel workflow requires only two inputs; the ligand structure file (SMI format) and the ePharmaLib dataset (PHAR format). The latter can be retrieved from Zenodo.
