In vitro study | 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. MI-773 is an advanced synthetic small molecule inhibitor, displays high binding affinity against MDM2 (K d =8.2 nM). |
In vivo study | 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 mm 3 at 20 days of treatment, compare to an average volume of 600 mm 3 for the 10 mg/kg group and 30 mm 3 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. |
