| General tips | For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |

| Description | MI-773 is a new small molecule inhibitor of the MDM2-p53 interaction, binds to MDM2 with high affinity (Ki=0.88 nM) and blocks the p53-MDM2 interaction.In Vitro:MI-773 potently induces expression of p53 and its downstream targets p21, MDM2, and induces phosphorylation of p53 (serine 392) in low passage primary human ACC cells. Notably, MI-773 induces a dose-dependent increase in the fraction of apoptotic ACC cells and in the fraction of cells in the G1 phase of cell cycle (P<0.05). Consequently, MI-773 causes apoptotic cell death[1]. MI-773 is an advanced synthetic small molecule inhibitor, displays high binding affinity against MDM2 (Kd=8.2 nM)[2].In Vivo:MI-773 at 10 mg/kg modestly reduces the rate of tumor growth, whereas 100 mg/kg causes significant tumor regression. Control tumors reach an average of 1,000 mm3 at 20 days of treatment, compare to an average volume of 600 mm3 for the 10 mg/kg group and 30 mm3 for the 100 mg/kg group. Kaplan-Meier analysis shows an increase in tumor failure, define as two times increase in tumor volume as compared to pretreatment volume (P=0.044), for vehicle-treated mice when compare to mice treated with 100 mg/kg MI-773[1].

MI-773 is a small molecule inhibitor of MDM2 with IC50 value of 62nM [1].
MI-773 is a small molecule MDM2 antagonist. It is a spirooxindole derivative. MI-773 shows a high MDM2 affinity with IC50 value of 62nM in the FP competitive binding experiment. In the in vitro cell-based assay, MI-773 shows a similar inhibition efficacy with its enantiomer MI-77301. The GI50 values are 58nM and 33nM for MI-773 and MI-77301, respectively. Both MI-773 and MI-77301 exert considerable activity at dose of 100 mg/kg in mouse xenograft models of osteosarcoma, prostate cancer, colorectal cancer, leukemia or melanoma. Currently, an international and multicenter phase I trial of MI-773 is underway for patients with liposarcomas and other p53-wild-type tumors [1, 2].

Novel MDM2 inhibitor SAR405838 (MI-773) induces p53-mediated apoptosis in neuroblastoma.[Pubmed:27764791]
Oncotarget. 2016 Dec 13;7(50):82757-82769.
Neuroblastoma (NB), which accounts for about 15% of cancer-related mortality in children, is the most common childhood extracranial malignant tumor. In NB, somatic mutations of the tumor suppressor, p53, are exceedingly rare. Unlike in adult tumors, the majority of p53 downstream functions are still intact in NB cells with wild-type p53. Thus, restoring p53 function by blocking its interaction with p53 suppressors such as MDM2 is a viable therapeutic strategy for NB treatment. Herein, we show that MDM2 inhibitor SAR405838 is a potent therapeutic drug for NB. SAR405838 caused significantly decreased cell viability of p53 wild-type NB cells and induced p53-mediated apoptosis, as well as augmenting the cytotoxic effects of doxorubicin (Dox). In an in vivo orthotopic NB mouse model, SAR405838 induced apoptosis in NB tumor cells. In summary, our data strongly suggest that MDM2-specific inhibitors like SAR405838 may serve not only as a stand-alone therapy, but also as an effective adjunct to current chemotherapeutic regimens for treating NB with an intact MDM2-p53 axis.
