描述 | MDM2 binds the p53 tumor suppressor protein with high affinity and negatively modulates its transcriptional activity and stability. Overexpression of MDM2, found in many human tumors, effectively impairs p53 function. Inhibition of MDM2-p53 interaction can stabilize p53 and may offer a novel strategy for cancer therapy[3]. Nutlin 3a is the active enantiomer of nutlin-3, inhibiting the p53/MDM2 interaction, and IC50 was 90 nM in the cell-free test[4]. In vitro, Nutlin-3a replaces p53 from the binding pocket of the MDM2 protein, thereby releasing p53 from a state of inhibition and proteasome degradation, leading to induction of downstream targets, cell cycle arrest and apoptosis. Incubation for 10 μM Nutlin-3a for 7 days resulted in growth inhibition of NIH3T3 cells of over 90%[5]. Nutlin-3a effectively reduced S-phase cells to 0.2-2% and increased G1- and G2/M- phase cells[5]. After 40 h, Nutlin-3a induced apoptosis in about 60% of SJSA-1 and MHM cells, while at 60 h, the apoptotic cells reached 85% and 65%, respectively[5]. In vivo, Nutlin-3a inhibits xenograft growth in a dose-dependent manner, showing large tumor contractions at the highest dose (200 mg/kg). Nutlin-3a is a selective activator of the p53 pathway in vivo and highly effective against SJSA-1 osteosarcoma. Tumors with wild-type p53 and MDM2 amplification responded best to nutlin-3a therapy[5]. |
