FASTDock: A Pipeline for Allosteric Drug Discovery

Area of Science:

• Biochemistry
• Pharmacology
• Drug Discovery

Background:

• Allosteric modulation is vital in biological processes and human diseases, making it a key target for therapeutic development.
• Identifying allosteric sites and suitable small-molecule modulators presents significant challenges in drug discovery due to a lack of prior ligand information.

Purpose of the Study:

• To introduce FASTDock, a novel computational pipeline designed to uncover ligandable allosteric sites.
• To identify small molecules capable of targeting these newly discovered allosteric sites without relying on existing ligand data.

Main Methods:

• Development of a novel drug discovery pipeline named FASTDock.
• Implementation of a hierarchical screening strategy to analyze a large database of potential ligands.
• Uncovering ligandable allosteric sites and corresponding small-molecule binders.

Main Results:

• FASTDock successfully identifies potential allosteric binding sites on receptors.
• The pipeline can discover small molecules that effectively target these identified allosteric sites.
• Demonstrated ability to proceed without pre-existing knowledge of ligands for the target site.

Conclusions:

• FASTDock offers a new approach to overcome limitations in allosteric drug discovery.
• This pipeline facilitates the identification of novel allosteric targets and lead compounds.
• Enables high-throughput screening for a vast chemical space, accelerating therapeutic development.
