Epigenetic Target Profiler: A Web Server to Predict Epigenetic Targets of Small Molecules

Motivation: The identification of protein targets of small molecules is essential for drug discovery. With the increasing amount of chemogenomic data in the public domain, multiple ligand-based models for target prediction have emerged. However, these models are generally biased by the number of known ligands for different targets, which involves an underrepresentation of epigenetic targets. Epigenetic drug discovery is of increasing importance but there are no open tools for epigenetic target prediction.

Results: We introduce Epigenetic Target Profiler (ETP), a freely accessible and easy-to-use web application for the prediction of epigenetic targets of small molecules. For a query compound, ETP predicts its bioactivity profile over a panel of 55 different epigenetic targets. To that aim, ETP uses a consensus model based on two binary classification models for each target, relying on support vector machines and built on molecular fingerprints of different design. A distance-to-model parameter related to the reliability of the predictions is included to facilitate their interpretability and assist the identification of small molecules with potential epigenetic activity.
