RG7112 (RO5045337) is the first-in-class small-molecule MDM2 inhibitor designed to occupy the p53-binding pocket of MDM2. In cancer cells expressing wild-type p53, RG7112 stabilizes p53 and activates the p53 pathway, leading to cell cycle arrest, apoptosis, and inhibition or regression of human tumor xenografts.

| Results | The in vivo relevance of the combined actions of MDM2 inhibition and TRAIL agonists was tested using a xenograft mouse model that recapitulates sarcomatoid MPM with WT p53. Interestingly, our results demonstrated that RG7112 plus rhTRAIL significantly reduced tumor growth compared to the mock-treated group |

| Nutlin-3
Nutlin-3 is a selective MDM2 (mouse double minute 2) antagonist with IC50 of 90 nM. Nutlin-3 induces apoptosis in cancer cells. Nutlin-3 treatment induces the expression of MDM2 and p21, and displays potent antiproliferative activity with IC50 of ~1.5 μM in cells with wild-type p53 such as HCT116, RKO and SJSA-1. |
| NSC 66811
NSC 66811 is a potent MDM2 inhibitor with Ki value of 120 nM, which disrupts MDM2-p53 interaction and activates p53 function. |
| Nutlin-3a
Nutlin-3a, the active enantiomer of Nutlin-3, is a potent murine double minute (MDM2) inhibitor (IC50=90 nM). Nutlin-3a inhibits the p53/MDM2 interaction with IC50 of 90 nM. |
| Nutlin-3b
Nutlin-3b is a p53/MDM2 antagonist or inhibitor with IC50 value of 13.6 μM, 150-fold less potent (+)-enantiomer of Nutlin-3 as in comparison with opposite enantiomer Nutlin-3a. |
| SL-01
SL-01 is a p53-Mdm2 interaction inhibitor with IC50 of 3.18 μM. |
