O=c1[nH]c(=O)c2c(nc3n(-c4ccccc4)c(-c4ccccc4)cn23)[nH]1
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.
