LiGen: a high performance workflow for chemistry driven de novo design

Area of Science:

• Computational chemistry
• Drug discovery
• Cheminformatics

Background:

• Molecular de novo design tools are crucial for identifying novel chemical structures with specific biological properties.
• Existing methods often face challenges in efficiency and structural novelty.

Purpose of the Study:

• To present LiGen, a versatile suite of programs for molecular de novo design.
• To enable efficient identification of structurally new chemotypes with desired biological properties.

Main Methods:

• LiGen utilizes a combination of structure-based (active site identification) and ligand-based (pharmacophore definition) approaches.
• It features a pharmacophore-based docking procedure allowing flexible docking without conformer enumeration.
• Accurate reactant mapping and tagging via substructure searching are key functionalities.

Main Results:

• LiGen modules can be used sequentially or as stand-alone tools.
• The software supports user-defined workflows for project-centric applications.
• It facilitates the generation of novel chemical structures with predefined properties.

Conclusions:

• LiGen offers a flexible and efficient platform for molecular de novo design.
• Its unique features enhance the identification of novel chemotypes for drug discovery.
• The suite provides a comprehensive solution for computational chemists and drug designers.
