GtoPdb Ligand ID: 4512

Abbreviated name: NBMPR
Synonyms: NBTI | nitrobenzylthioinosine
Compound class: Synthetic organic
Comment: NBMPR is a equilibrative nucleoside transporter 1 (ENT1) inhibitor. Alternative isomeric structures are reported including the (2R,3S,4R,5R) form that has PubChem CID 65407. NBMPR is chemically distinct from dilazep and crystallisation and mutagenesis studies show that these two inhibitors utilise different binding mechanisms at ENT1 [6]. The crystal structure of ENT1 in complex with NBMPR is deposited in the Protein Data Bank under accession code 6OB6 [6]..
