GtoPdb Ligand ID: 5709

Synonyms: SGX523
PDB Ligand
Compound class: Synthetic organic
Comment: SGX-523 is an ATP-competitive, highly selective inhibitor of the receptor tyrosine kinase, hepatocyte growth factor receptor (MET) [1] [2]. While Buchanan et al. [1] include three PDB structures linked via PubMed to MMDB entries, two of them depict a charge-state tautomer of SGX-523. These thus point to a different compound PubChem CID 42628064 but the PDB link above points to the correct ligand structure. Note also, becasue of its established specificity, this now has a SGC Probe Portal entry SGX-523.
