A Bemis-Murcko scaffold is what remains of a molecule when every side chain is removed: the rings and the chains that link them. Chemicals that share a scaffold often belong to the same compound series, which helps when you look for analogues, alternative suppliers or related building blocks.
Computed from the structures of the chemicals listed here. Stereo and charges are removed before the scaffold is taken.
