ETC-501
Based on 1 Customer Validation
ETC-501 is a blood-brain barrier-permeable, orally active, and selective MNK1/MNK2 inhibitor, with an IC50 of 0.033 μM against MNK1 and 0.111 μM against MNK2. ETC-501 inhibits glioblastoma cell proliferation, impairs DNA damage repair function, delays cell cycle progression, and suppresses ribosome biogenesis. ETC-501 enhances Temozolomide (HY-17364)-induced cellular senescence, attenuates the senescence-associated secretory phenotype, and increases cellular sensitivity to Navitoclax (HY-10087). ETC-501 is applicable to research related to glioblastoma.

Biological Activity
ETC-501 (0-20 μM; 24 h) dose-dependently inhibits eIF4E phosphorylation and reduces Cyclin D1 protein levels in LN-229 and T98G glioblastoma cells[1].
ETC-501 (0-10 μM) inhibits the viability of LN-229 and T98G glioblastoma cells with GI50 values of 4.035 μM and 6.122 μM, respectively, and reduces the tumor sphere-forming capacity and stem cell frequency of patient-derived GPCs[1].
ETC-501 (0-10 μM; 4 h) impairs DNA synthesis in LN-229, T98G and U-87MG glioblastoma cells in a dose-dependent manner[1].
ETC-501 (8 h) impairs G1-to-S phase progression in Palbociclib (HY-50767)-synchronized LN-229 and U-87MG glioblastoma cells[1].
ETC-501 (5-10 μM; 14 days) induces cellular senescence in LN-229 and U-87MG glioblastoma cells[1].
ETC-501 (5-10 μM; 10 days) reduces the levels of key inflammatory cytokines and chemokines, including IL-6, IL-8 and CCL2[1].
ETC-501 (10 μM; 6 days) and TMZ (HY-17364) drives LN-229 glioblastoma cells into a senescence priming state, and significantly enhances their sensitivity to Navitoclax (HY-10087)-induced cell death and apoptosis[1].

Animal Model:NOD-SCID gamma (NSG, NOD.Cg-PrkdcscidIl2rgtm1wjl/SzJ) (6-8-week-old male; subcutaneous glioblastoma model)[1]
-
Dosage:100 mg/kg
-
Administration:oral gavage; daily; 21 days
-
Result:Reduced excised tumor p-eIF4E levels by ~50%.
Induced senescent tumor cells (SA-β-gal positive) when combined with TMZ, with non-statistically significant trend toward higher SA-β-gal and p21 levels compared to TMZ alone.
Resulted in widespread tumor necrosis, near absence of SA-β-gal-positive cells, and markedly reduced p21 expression when combined with TMZ and navitoclax.

Animal Model:NOD-SCID gamma (NSG, NOD.Cg-PrkdcscidIl2rgtm1wjl/SzJ) (6-8-week-old male; orthotopic intracranial glioblastoma model)[1]
-
Dosage:100 mg/kg
-
Administration:oral gavage; daily; 21 days
-
Result:Reduced p-eIF4E levels in contralateral and ipsilateral brain tissue by ~60%.
Did not significantly extend survival compared to vehicle control when administered alone.
Showed non-statistically significant trend toward improved survival compared to TMZ alone, and induced senescence (SA-β-gal positive) in orthotopic tumors when combined with TMZ.
Did not improve survival beyond TMZ alone when combined with TMZ and navitoclax, with residual SA-β-gal-positive senescent cells detected post-treatment.

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.
