Exploring Structural Relationships between Bioactive and Commercial Chemical Space and Developing Target Hypotheses...

Area of Science:

• Medicinal Chemistry
• Cheminformatics
• Drug Discovery

Background:

• Vast chemical libraries exist, but many commercial compounds lack biological annotation.
• Understanding structural relationships between bioactive and commercial compounds is crucial for drug discovery.

Purpose of the Study:

• To identify unexplored biological potential within commercial chemical space.
• To generate novel target hypotheses for unannotated compounds using analog series-based scaffolds.
• To facilitate hit expansion and library design in drug discovery.

Main Methods:

• Systematic extraction of analog series from bioactive and commercial compound databases.
• Generation of analog series-based (ASB) scaffolds.
• Derivation of target profiles and identification of shared ASB scaffolds between bioactive and commercial compound sets.

Main Results:

• Identified extensive unexplored biological potential in commercial chemical space.
• Established structural links between bioactive and commercial compounds via shared ASB scaffolds.
• Generated target hypotheses for over 37,000 compounds across more than 1000 targets.

Conclusions:

• The study successfully linked commercial compounds to potential biological targets, expanding drug discovery avenues.
• Freely available data on commercial molecules with new target hypotheses and key scaffolds will accelerate research.
• This approach offers valuable insights for hit expansion, library design, and lead optimization.
