Scaffold Hunter: a comprehensive visual analytics framework for drug discovery
Algorithm-- All terminal side chains are cut off. double bonds attached to the ring are preserved.
-A ring is removed one at a time while preserving the core structure, until only a scaffold with a single ring is left.
-virtual scaffolds- scaffolds not directly obtained from any molecule in the collection but generated by pruning-- purposeful for synthesis of compounds that complement the collection
Scaffold hunter uses sequential hierarchial non-overlapping clustering
Useful for scaffold hopping, target prediction
