Scipion-Chem: An Open Platform for Virtual Drug Screening

Area of Science:

• Computational Chemistry
• Drug Discovery
• Bioinformatics

Background:

• Virtual drug screening (VDS) computationally reduces the number of molecules needing experimental testing for drug discovery.
• Existing VDS approaches focus on receptor structure (structure-based) or ligand characteristics (ligand-based).
• Scipion is a workflow engine for structural studies of biological macromolecules.

Purpose of the Study:

• Introduce Scipion-chem, a new branch of Scipion specifically designed for VDS.
• Provide an accessible, interoperable, and traceable platform for executing VDS workflows.
• Enhance VDS by integrating common VDS programs and developing consensus protocols.

Main Methods:

• Integration of 11 plugins from popular VDS programs into the Scipion workflow engine.
• Development of consensus protocols to combine results from multiple VDS programs for improved prediction robustness.
• Utilizing the Scipion graphical user interface for executing and analyzing VDS tasks.
• Ensuring interoperability between different software packages and tracking of all intermediate files, parameters, and user decisions.

Main Results:

• Scipion-chem offers a unified platform for VDS tasks through its graphical user interface.
• Integrated plugins enable the execution of standard VDS procedures.
• Consensus protocols provide more robust predictions by combining multiple VDS program outputs.
• Scipion-chem facilitates seamless software interoperability and maintains a detailed audit trail.

Conclusions:

• Scipion-chem is a comprehensive and user-friendly platform for virtual drug screening.
• The platform enhances drug discovery efficiency through integrated tools and robust prediction methods.
• Scipion-chem promotes accessibility, interoperability, and traceability in VDS workflows.
• The software is openly available for researchers to conduct successful VDS.
