GNA002 is a highly potent, specific and covalent EZH2 (Enhancer of zeste homolog 2) inhibitor with an IC50 of 1.1 μM. GNA002 can specifically and covalently bind to Cys668 within the EZH2-SET domain, triggering EZH2 degradation through COOH terminus of Hsp70-interacting protein (CHIP)-mediated ubiquitination. GNA002 efficiently reduces EZH2-mediated H3K27 trimethylation, reactivates polycomb repressor complex 2 (PRC2)-silenced tumor suppressor genes.

Description

GNA002 is a highly potent, specific and covalent EZH2 (Enhancer of zeste homolog 2) inhibitor with an IC50 of 1.1 μM. GNA002 can specifically and covalently bind to Cys668 within the EZH2-SET domain, triggering EZH2 degradation through COOH terminus of Hsp70-interacting protein (CHIP)-mediated ubiquitination. GNA002 efficiently reduces EZH2-mediated H3K27 trimethylation, reactivates polycomb repressor complex 2 (PRC2)-silenced tumor suppressor genes[1].

IC50 & Target[1]

EZH2

1.1 μM (IC50)

In Vitro

GNA002 (10 μM; 72 hours) clearly inhibits the proliferation of numerous cancer cell lines with IC50s of 0.070 μM and 0.103 μM for MV4-11 and RS4-11[1].
GNA002 (2 μM; 24 hours) demonstrates an elevated capacity to induce cell death in human cancer cells[1].
GNA002 (0.1-4 μM; 48 hours) efficiently reduces EZH2-mediated H3K27 trimethylation in Cal-27 head and neck cancer cells[1].

Cell Proliferation Assay[1]

Cell Line: Numerous cancer cell lines
Concentration: 10 μM
Incubation Time: 72 hours
Result: Inhibited the proliferation of numerous cancer cell lines with IC50s of 0.070 μM and 0.103 μM for MV4-11 and RS4-11.

Apoptosis Analysis[1]

Cell Line: HN-4 and Cal-27 head and neck cancer cells
Concentration: 2 μM
Incubation Time: 24 hours
Result: Induced cellular apoptosis in human cancer cells.

Western Blot Analysis[1]

Cell Line: Cal-27 head and neck cancer cells
Concentration: 0.1, 0.2, 0.5, 1, 2, 4 μM
Incubation Time: 48 hours
Result: Reduced H3K27Me3 levels.
In Vivo

GNA002 (oral administration; 100 mg/kg; daily) significantly decreases the volumes of Cal-27-derived tumors and reduces H3K27Me3 levels in tumor tissues. GNA002 also significantly suppresses the in vivo tumor growth derived from the xenografted A549 lung cancer cells, Daudi and Pfeiffer cells. GNA002 inhibits the aberrant oncogenic functions of EZH2, thus inhibiting tumor growth in vivo, at least in the xenograft experimental model[1].

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

Animal Model: Male BALB/C Nude mice aged 30-35 days and weighing 18-22 g, bearing Cal-27 xenograft tumors[1]
Dosage: 100 mg/kg
Administration: Oral administration; daily
Result: Decreased the size and weight of tumors formed by Cal-27 cells.

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    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 1.25 mg/mL (1.78 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 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

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

    Solubility: 1.25 mg/mL (1.78 mM); Suspended solution; Need ultrasonic

    This protocol yields a suspended solution of 1.25 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

    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.

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.
