Find larger chemical diversity

A field-based virtual screening software package designed to find candidate molecules with larger chemical diversity.

The Problem

The limited number of diverse molecular scaffolds, the absence of ideas to propose to medicinal chemistry teams, the dearth of alternative backup compounds to current chemical series, projects stopped because of intellectual property issues, undesired compound properties related with solubility, toxicology… These are just some of the main problems that cause a drug discovery project to fail.

PharmScreen Logo

Our field-based virtual screening software uses a unique and superior 3D representation of molecules based on electrostatic, steric and hydrophobic interaction fields derived from semi-empirical Quantum-Mechanics (QM) calculations. Such fields describe with high accuracy the factors that determine ligand / receptor interactions. These chemo-type agnostic descriptors allow PharmScreen identifying candidate molecules with similar physico-chemical properties to reference compound/s, and different and diverse molecular scaffolds.

PharmScreen is peer-reviewed and validated. See our publications for more information.

Workflow

workflow

Our field-based virtual screening software requires only two input files: a reference (i.e. bioactive conformation) and a library. Different formats are accepted.

Multiple basic (minimization, conformer generation, charges and field generation) and advanced options are available during the configuration step. Once reference and library are prepared, they can be used for different virtual screening campaigns. PharmScreen compares molecular fields calculated during the preparation step in order to rank your library molecules based on fields similarity.

Result files allow to evaluate the similarity score between two molecules as well as to visualize the chemical structures and calculated fields using our SaaS platform.
