Nutlin-3b is an inactive enantiomer of nutlin-3 [1].
Nutlin-3 is a small-molecule inhibitor of MDM2, interfering with MDM2-directedTP53 degradation. The stabilization of WT-TP53 leads to cell cycle arrest, growth inhibition, and apoptosis. As an inactive enantiomer, Nutlin-3b does not show any effect on the proliferation and has no insignificant effect on gene expression in cancer cells. Nutlin-3b binds MDM2 with about 200-fold lower affinity and is 150 times less active than 3a (an active enantiomer of nutlin-3). Nutlin-3b is usually used as a negative control. It shows no induction of MDM2, p53 or p21 expression and has no ability in colony-formation in H460 cell line. It also has no effect on cell cycle [1, 2].
