RG-7112 is an inhibitor of mouse double-minute 2 protein (MDM2; IC50 = 0.018 μM), an E3 ubiquitin ligase that ubiquitinates the tumor suppressor p53 and also acts as a negative regulator of p53 transcriptional activity.1 RG-7112 binds to the p53 binding pocket of MDM2. It increases the levels of p53 and its transcriptional targets in SJSA-1 osteosarcoma cells.1,2 It inhibits proliferation in cancer cell lines expressing wild-type p53 (IC50s = 0.18-2.2 μM) and cell lines expressing mutant p53 (IC50s = 5.7-20.3 μM). RG-7112 also prevents and reduces tumor growth in an SJSA-1 mouse xenograft model when administered at doses of 50 and 100 mg/kg per day, respectively.2 However, it inhibits thrombopoiesis in vivo, decreasing platelet counts in rats when administered at doses of 50 and 100 mg/kg and in cynomolgus monkeys at doses of 10 and 20 mg/kg.3 | [Uses]
RG 7112 is MDM2 antagonist. It can be used in biological study of single mouse analysis on evaluation of alternative in vivo drug screening methodology. | [in vivo]
RG7112 (25-200 mg/kg, single oral dose) activates p53 pathway and induces apoptosis in tumor cells in vivo[2].
?
RG7112 (100 mg/kg, gavage once per day, 5 days/week for 3 weeks ) reduces tumor growth rate and increases survival in GBM models[3]. | Animal Model: | Female Balb/c nude mice[2]. | | Dosage: | 25-200 mg/kg. | | Administration: | Orally, single dose. | | Result: | At the highest dose level of RG7112 (200 mg/kg) only 1.2% (± 0.89 SD) of cells incorporated BrdU at 24 h post-dosing, vs. 14% (± 1.83 SD) of vehicle treated tumors.
|
| Animal Model: | GBM cells were implanted into the brain of Athymic Nude mice (7 weeks old females, 10 animals/group)[3]. | | Dosage: | 100 mg/kg. | | Administration: | Oral gavage, once per day, 5 days/week for 3 weeks. | | Result: | Reduced tumor growth rate and increases survival in heterotopic and orthotopic animal models bearing MDM2-amplified GBM. |
