描述 | Tumor suppressor p53 is a powerful growth suppressive and pro-apoptotic protein that plays a central role in protectionfrom tumor development. The overproduction of MDM2 (murine double minute 2), the primary negative regulator of p53, effectively disables p53 function[3]. NSC 66811, a novel inhibitor of the MDM2-p53 interaction, binds to MDM2 with a Ki of 120 nM and activates p53 in cancer cells with a mechanism of action consistent with targeting the MDM2-p53 interaction[2]. HepG2 cells were treated for 24 h with NSC 66811 (5 and 25 μmol/L), and the p53 mRNA levels were upregulated by NSC 66811 without affecting the CYP expression. Addition of the p53 activator NSC 66811 (3, 10, 25 μmol/L) in HepG2 cells dose-dependently inhibited the metabolism of DEM (dextromethorphan) and TEST (testosterone). For CYP3A4, the metabolism of TEST was reduced by 1.5-, 2.9-, and 6.8-fold with 3, 10, and 25 μmol/L of NSC 66811, respectively, indicating that p53 activation decreased the metabolic efficiency through both CYP2D6 and 3A4[1]. |
作用机制 | NSC 66811 mimics three p53 residues critical in the binding to MDM2[2]. |
