GtoPdb Ligand ID: 7000

PDB Ligand
Compound class: Natural product
Comment: Curcumin's physicochemical properties imply that it is an implausible clinical lead [30]. It is unstable, reactive, and nonbioavailable, and has been identified as having attributes of both PAINS (pan-assay interference compounds) and IMPS (invalid metabolic panaceas) compounds.
