Other Notes

Relative stereochemistry; racemic mixture of (4R, 5S) and (4S, 5R) enantiomers.


Nutlin-3 has been used:
• as a drug to stimulate p53 functions in gene transfer experiment
• to inject worms to verify the prevalent role of translationally controlled tumor protein (TCTP) in posterior amputated Eeugeniae
• as a p53 activator in cyclotherapy studies
• as an mdm2 inhibitor to know its effect on p53 levels, cleaved caspase 3 and Poly (ADP-ribose) polymerase (PARP) cleavage


1, 5 mg in glass bottle

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.

Nutlin-3 is a Mdm2 (mouse double minute 2) antagonist, p53 pathway activator, and apoptosis inducer.
