Methodological study demonstrates high scaffold-hopping capability of extended reduced graph descriptors across drug activity classes, indicating enhanced virtual screening efficiency.

Key Points

To introduce and evaluate an extended reduced graph (ErG) methodology using pharmacophore-type node descriptions to enhance molecular abstraction and scaffold hopping in similarity searches.
Developed a 2D hybrid descriptor combining reduced graph representations with binding property pairs, incorporating extensions for pharmacophoric properties, size, and shape.
Benchmarked retrieval performance against DAYLIGHT fingerprints across 11 biological activity classes from the MDL Drug Data Report database.
ErG achieved equal or superior retrieval performance compared to DAYLIGHT fingerprints in 10 out of 11 tested activity classes.
The method successfully identified structurally distinct active chemotypes via low-dimensional descriptor vectors, enabling fast computational search times.
