| Description | SLMP53-2 is a mutant p53 reactivator that restores the wild-type-like conformation and DNA-binding ability of mutp53-Y220C through enhanced interaction with Hsp70, thereby reinstating p53's transcriptional activity. This compound induces cell cycle arrest, apoptosis, and endoplasmic reticulum (ER) stress, displaying antitumor activity [1] [2]. |
| In vitro | SLMP53-2(3.12-50 μM;48小时)对HuH-7和HCC1419细胞的增殖有抑制作用,并显示出相似的IC 50值。相比之下,SLMP53-2在非肿瘤HFF-1细胞中的生长抑制活性明显减弱(IC 50为50 µM)[1]。此外,SLMP53-2(14-28 μM;48-72小时)能诱导HuH-7细胞在G0/G1期发生细胞周期阻滞,并引起细胞凋亡[1]。在持续14天的实验中,SLMP53-2(0.9-14 μM)对HuH-7细胞集落的形成显示出浓度依赖的抑制效果[1]。在24小时内,28 μM浓度的SLMP53-2能够提高HuH-7细胞中XBP1核蛋白、剪接XBP1(sXBP1)mRNA以及磷酸化eIF2α的水平[1]。SLMP53-2(14 μM;16-48小时)可增加HuH-7细胞中MDM2、p21、GADD45、BAX和KILLER的蛋白表达,降低生存素和VEGF的水平,而这些作用在HuH-7 p53KO细胞中不再出现[1]。此外,1.5 μM的SLMP53-2能增强HuH-7细胞对Sorafenib的敏感性[1]。 |
| In vivo | SLMP53-2(50 mg/kg;i.p.,五次给药)能有效缩小携带HuH-7异种移植物裸鼠的肿瘤体积及重量,并未观察到显著的毒性副作用[1]。 |
