Wild-type p53-induced phosphatase 1 (PPM1D) (IC50=0.6 μM) [2]
- Mammalian target of rapamycin (mTOR) (indirect activation,) [1] |
|---|---|
| 体外研究 (In Vitro) |
CCT007093(25 或 50 µM,8 小时)显着提高 mTOR Ser2448、Ser2481 和 Ser2159 的磷酸化水平。在转染的 HEK293T 细胞系中,p70S6K (Thr389) 和 S6 (Ser235/236) 的磷酸化水平也上调 [1]。 CCT007093 对 MCF-7 细胞表现出选择性,导致两天后活力下降 40%,但对 HeLa 细胞生长没有明显影响[2]。在对 PPM1D 抑制敏感的 MCF-7 细胞中,CCT007093 暴露后四小时会导致 P38 磷酸化。在对 PPM1D 抑制相对抵抗的 HeLa 细胞中,CCT007093 不会诱导 P38 磷酸化[2]。
CCT007093 对过表达PPM1D的细胞系(HCT116 p53-/- PPM1D+/+、U2OS PPM1D过表达细胞)具有选择性增殖抑制作用,IC50值在0.5-2 μM之间,而对PPM1D低表达或缺失细胞系(HCT116 p53-/- PPM1D-/-、MCF-7)抑制作用微弱[2] - CCT007093 处理过表达PPM1D的细胞后,可上调p53蛋白稳定性及磷酸化水平(Ser15位点),同时增加p21、Bax等p53靶基因的mRNA和蛋白表达,诱导细胞周期阻滞于G1期并促进凋亡[2] - 体外培养的原代小鼠肝细胞中,CCT007093 可浓度依赖性激活mTOR信号通路,显著提高p-mTOR(Ser2448)、p-S6核糖体蛋白(Ser235/236)的磷酸化水平,促进肝细胞增殖,且该效应可被mTOR抑制剂雷帕霉素阻断[1] - CCT007093 对PPM1D的磷酸酶活性具有直接抑制作用,在体外酶促反应中,1 μM浓度即可抑制约50%的PPM1D活性,且对其他磷酸酶(如PP2Cα、PP1)无明显抑制作用,体现出靶点选择性[2] |
| 体内研究 (In Vivo) |
接受主要肝切除术的小鼠在接受 CCT007093 (6.4 mg/kg) 治疗后具有更高的存活率和更多的肝脏再生能力[1]。
小鼠70%部分肝切除(PHx)模型中,术后腹腔注射CCT007093(5 mg/kg)可显著促进肝再生,术后48小时和72小时的肝重/体重比分别较对照组提高15%和22%,肝细胞增殖标志物Ki67的阳性率从对照组的35%升高至58%[1] - 肝再生模型中,CCT007093 处理组小鼠肝组织中p-mTOR、p-S6的磷酸化水平显著升高,而PPM1D的蛋白表达无明显变化,提示其通过抑制PPM1D间接激活mTOR通路,加速肝细胞增殖和肝组织修复[1] - 未观察到CCT007093 在体内对正常肝组织产生明显损伤,肝再生过程中血清ALT、AST水平与对照组无显著差异[1] |

| 动物实验 |
Animal/Disease Models: Wild-type mice[1].
Doses: 3.2 and 6.4 mg/kg. Route of Administration: Injected intraperitoneally 4 times (mice were sacrificed at 36 h post-PH). Experimental Results: Dramatically improved survival in mice following major hepatectomy (80% hepatectomy). The level of PCNA was also Dramatically increased in the liver of CCT007093-treated mice at 36h, 48h and 72h post-PH. Mouse liver regeneration experiment: 8-10 week-old C57BL/6 mice were adaptively fed for 1 week, then subjected to 70% partial hepatectomy. Twenty-four hours after surgery, CCT007093 was administered by intraperitoneal injection at a dose of 5 mg/kg, once every 24 hours for 3 consecutive days. The drug was dissolved in a small amount of DMSO and then diluted with normal saline to a final DMSO concentration of ≤5% [1] - Experimental grouping: A control group (given an equal volume of normal saline containing 5% DMSO) and a CCT007093 treatment group were set up, with 10 mice in each group. Mice were sacrificed at 24 hours, 48 hours, and 72 hours after surgery, and liver tissue and serum were collected for Western blot, immunohistochemistry (Ki67), and serum biochemical index detection [1] |

| 其他信息 |
CCT007093 is the first reported selective small molecule PPM1D inhibitor that inhibits the phosphatase activity of PPM1D by directly binding to the catalytic domain of PPM1D [2]. The mechanism by which CCT007093 selectively kills PPM1D-overexpressing tumor cells is related to the restoration of p53 pathway function. PPM1D overexpression usually leads to accelerated p53 degradation, while drug inhibition of PPM1D can stabilize p53 and initiate cell cycle arrest and apoptosis [2]. In the process of liver regeneration, the activation of the mTOR pathway by CCT007093 is independent of p53, but is achieved by inhibiting the dephosphorylation of mTOR by PPM1D, which provides a potential target for regenerative therapy after liver injury [1]. CCT007093 has no obvious cytotoxicity to normal cells and only works under PPM1D overexpression or specific physiological states (such as liver regeneration), showing potential therapeutic safety [1][2].
