ScafBank: a public comprehensive Scaffold database to support molecular hopping

Area of Science:

• Medicinal Chemistry
• Computational Chemistry
• Drug Discovery

Background:

• Optimizing lead compounds and finding molecules with similar bioactivities are key challenges in drug discovery.
• Scaffold hopping, or molecular hopping, utilizes in silico methods to explore novel chemical structures.
• A publicly searchable database for unique scaffolds is needed to facilitate drug design.

Purpose of the Study:

• To create a publicly searchable database of unique molecular scaffolds.
• To support the optimization of lead compounds and the design of novel bioactive molecules.

Main Methods:

• Systematic analysis of commercially available small molecule and bioactive compound databases.
• Identification and storage of unique scaffolds in a relational database.
• Annotation of scaffolds with molecular properties and associated bioactive compound information.

Main Results:

• A database containing 241,824 unique scaffolds was constructed from approximately 4,800,000 compounds.
• Each scaffold entry includes molecular properties (e.g., molecular weight, logP, H-bond donors/acceptors, rotatable bonds, ring count).
• Scaffolds from bioactive compounds are linked to their original molecules and target information.

Conclusions:

• The developed Web-based database system aids medicinal and organic chemists.
• It facilitates the design of novel molecules with desired properties based on unique scaffolds.
• This resource streamlines the search for new chemical entities in drug development.
