In vitro: MI-773 binds to MDM2 with Ki of 0.88 nM. MI-773 potently inhibits cell growth in cancer cell lines, including SJSA-1 (IC50, 0.092 μM), RS4;11 (IC50, 0.089 μM), LNCaP (IC50, 0.27 μM), and HCT-116 (IC50, 0.20 μM) cells, and displays high selectivity over cancer cell lines with mutated or deleted p53, including SAOS-2 (IC50, >10 μM), PC-3 (IC50, >10 μM), SW620 (IC50, >10 μM), and HCT-116 (p53-/-) (IC50, >20 μM) cells. In vivo: In the SJSA-1 osteosarcoma, acute lymphoblastic leukemia RS4;11, LNCaP prostate cancer, and HCT-116 colon cancer xenograft model, MI-773 (p.o.) effectively inhibits tumor growth in a dose-dependent manner (10 mg/kg, 30 mg/kg, 50 mg/kg, 100 mg/kg, and 200 mg/kg,).

| 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. |
