- Stored Murcko scaffold
- n1cncc(c1)-c2ccccc2
Registry normalization: MIGRATED_RAW. A registry entry does not establish drug approval or clinical use.
Molecules with the same Murcko scaffold
Exact matches to the stored ring-and-linker framework. Sharing a scaffold does not by itself establish activity or applicability to a model.
Calculated molecular properties
Stored descriptor calculations, not measured experimental values.
