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].
