O=c1c(C(c2ccccc2)c2c[nH]n(-c3ccccc3)c2=O)c[nH]n1-c1ccccc1

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.
