RG7112 is a selective inhibitor of p53-MDM2 binding that frees p53 from negative control, activating the p53 pathway in cancer cells leading to cell cycle arrest and apoptosis. [1]
P53 is a potent tumor suppressor that activates the transcription of a subset of genes controlling cell-cycle progression and apoptosis. MDM2 is a negative regulator of p53 that binds the transactivation domain of p53 and inhibits its ability to activate transcription. MDM2 is also an E3 ubiquitin ligase that targets p53 for proteosomal degradation. MDM2 overexpression is one of the mechanisms by which the wild type p53 function is impaired. [2]
RG7112 has been profiled extensively in many cell lines. In 15 cancer cell lines expressing wild-type p53, it shows IC50 in the range of 0.18 - 2.2 μM. However, the inhibition is much less in seven cancer cell lines with p53 mutation, IC50 5.7 - 20.3 μM. The overall selectivity is 14-fold.
In the animal models, RG7112-induced thrombocytopenia occurred rather late during the treatment period and persisted after drug discontinuation, suggesting that the drug acts on early hematopoietic progenitor cells. This is supported by the RG7112 ability to inhibit CFU-MK colonies formation by the CD34t cells in vitro. Administration of RG7112 in rats and monkeys reduces WBC counts and, to a lesser extent, hemoglobin levels. In patients treated with RG7112, neutropenia is among the serious adverse events while anemia occurred only in 2 of 20 patients. Interestingly, when tested in vitro, the same concentration of RG7112 that reduced CFU-MK colony formation do not significantly affect the formation of BFU-E and CFU-GM derived colonies.

Cell lines |
SJSA1 osteosarcoma cells |
|
Preparation method |
The solubility of this compound in DMSO is >10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37 °C for 10 minutes and/or shake it in the ultrasonic bath for a while.Stock solution can be stored below -20°C for several months. |

Reaction Conditions |
24 h; 10 μM |
|
Applications |
Treatment of cultured cancer cells with RG7112 led to concentration-dependent accumulation of p53 protein and its transcriptional targets, p21 and MDM2. RG7112 dose dependently inhibited the growth and killed SJSA1 osteosarcoma cells expressing high-levels of MDM2 protein due to MDM2 gene ampli fication |

Dosage form |
200 mg/kg; oral taken |
|
Applications |
Pharmocodynamic effects of RG7112 were assessed in the SJSA1 xenograft model. To assess the ability of RG7112 to activate p53 response in vivo, SJSA1 tumor-bearing mice were treated with a single dose of vehicle or 50 to 200 mg/kg RG7112 for 4 to 24 hours. Western blot analysis showed a dose-dependent increase in p53 protein and its targets, p21 and MDM2. The p53 protein levels were highest at 4 hours after dose and continue to persist at 24 hours at the highest dose level (200 mg/kg), whereas the duration of p53 modulation was shorter at lower dose levels. |

Other notes |
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |
