Description

E7016 (GPI 21016) is an orally available PARP inhibitor. E7016 can enhance tumor cell radiosensitivity in vitro and in vivo through the inhibition of DNA repair. E7016 acts as a potential anticancer agent[1][2].

IC50 & Target[1]

PARP

 

In Vitro

E7016 can enhance tumor cell radiosensitivity through the inhibition of DNA repair[1].
E7016 (3 μM)-mediated radiosensitization occurs through an increase in the number of cells undergoing mitotic catastrophe and not an increase in the number of cells undergoing apoptosis[1].
E7016 inhibits PARP by mimicking NAD+[2].

Apoptosis Analysis[1]

Cell Line: The U251 human glioblastoma cell line
Concentration: 3 μM
Incubation Time: 6 hours prior to irradiation and were stained at 24 and 72 h postirradiation
Result: The number of cells in mitotic catastrophe was significantly greater in the E7016-treated irradiated cells than in cells that received radiation only at 24 hours postirradiation.
In Vivo

E7016 has antitumor efficacy in murine xenograft studies[1].
Administration of E7016 (40 mg/kg; oral gavage) to mice bearing U251 xenografts enhances the effectiveness of the Temozolomide/radiation combination[1].
Mice treated with E7016/irradiation/Temozolomide have an additional growth delay of six days compared with the combination of Temozolomide and irradiation in vivo[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Four- to six-week-old female nude mice[3]
Dosage: 40 mg/kg
Administration: Oral gavage
Result: E7016 enhanced the radiation/Temozolomide (3 mg/kg orally)-induced tumor growth delay of U251 xenografts.

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 1.25 mg/mL (3.58 mM); Clear solution

    This protocol yields a clear solution of ≥ 1.25 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (12.5 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% Corn Oil

    Solubility: ≥ 1.25 mg/mL (3.58 mM); Clear solution

    This protocol yields a clear solution of ≥ 1.25 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (12.5 mg/mL) to 900 μL Corn oil, and mix evenly.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
