Top ten most frequent NP fragments in (a) ChEMBL pseudo-NPs and (b) NPs.70 (c) Occurrence of fragment combinations of ChEMBL pseudo-NPs (blue) and NPs (green).70 Examples of connectivity types are depicted below the graph with the NP fragments in purple and red. The black dots indicate common atoms due to the fusion patterns. cm = connection monopodal; fe = fusion edge; fs = fusion spiro; cbe = connection bipodal edge; fb = fusion bridged.
