| Description | MDMX/MDM2-IN-2 is a potent dual inhibitor of p53-MDM2/MDMX, demonstrating dissociation constants (Kis) of 0.23 μM for MDM2 and 2.45 μM for MDMX. It effectively disrupts the interaction between p53 and MDM2 proteins, thereby reinstating p53 functionality to induce cell cycle arrest and apoptosis. Additionally, this compound impedes cell migration and invasion, exhibiting notable antitumor activity [1]. |
| In vitro | MDMX/MDM2-IN-2 在 HCT116 和 SH-SY5Y 细胞中显示出中等的抗增殖作用,IC 50 值分别为 0.68 μM 和 0.54 μM。相较于肿瘤细胞,MDMX/MDM2-IN-2 对正常的 BEAS-2B 和 LO2 细胞的细胞毒性较低,IC 50 值分别为 17.96 μM 和 15.93 μM。在 0.6-2.4 μM 浓度、作用 48 小时的条件下,MDMX/MDM2-IN-2 能诱导 HCT116 和 SH-SY5Y 细胞走向凋亡,并引起细胞周期在 G1 期的停滞。同时,上述条件下也观察到 p53 及其下游效应分子 MDM2、MDMX、p21 和 cleaved-caspase3 的水平上升。在 0.4-0.8 μM 浓度下,MDMX/MDM2-IN-2 显著抑制 HCT116 和 SH-SY5Y 细胞的集落形成、迁移及侵袭性。 |
