Description
(±)-Nutlin-3 is a racemic mixture of the p53-Mdm2 protein-protein interaction inhibitor (−)-nutlin-3 and its less active enantiomer (+)-nutlin-3 .
In vivo, (±)-nutlin-3 (200 mg/kg twice daily) reduces tumor volume in an SJSA-1 osteosarcoma mouse xenograft model.
Uses
(+/-)-Nutlin-3 is a small molecule MDM2 antagonist.
Definition
ChEBI: 4-[[4,5-bis(4-chlorophenyl)-2-(4-methoxy-2-propan-2-yloxyphenyl)-4,5-dihydroimidazol-1-yl]-oxomethyl]-2-piperazinone is a stilbenoid.
Biochem/physiol Actions
Nutlin-3, an antagonist of a human homolog of murine double minute 2 (HDM2). It has the ability to inhibit the HDM2-directed degradation of p53. Nutlin-3 can also enhance the transcriptional activities of p73.
