CK2-TN03

Customer Review

Based on 1 Customer Validation

CK2-TN03 is an ATP-competitive casein kinase 2 (CK2) inhibitor, with an IC₅₀ of 165 nM and a K_i of 20 nM. CK2-TN03 inhibits CK2-mediated survivin activation and reduces CK2-dependent phosphorylation levels of BRD4/MYCN and AKT1. CK2-TN03 exerts anti-neuroblastoma effects by inhibiting survivin, leading to mitotic catastrophe and apoptosis of cancer cells. CK2-TN03 can be used in studies related to neuroblastoma.

In Vitro

CK2-TN03 (0.2-25.0 μM; 48 h) induces dose-dependent cell death in the medulloblastoma DAOY cell line and multiple neuroblastoma cell lines, with EC₅₀ values ranging from 0.31 to 1.95 μM; it shows no activity in glioblastoma U87 cells (EC₅₀ >25 μM)^[1].
CK2-TN03 (0.35-1.0 μM; 48 h) activates caspase 3/7 in CHP-212 neuroblastoma cells in a time-dependent manner, and primarily induces caspase-dependent apoptosis^[1].
CK2-TN03 (0.5-1.0 μM; 24-48 h) induces G2/M cell cycle arrest and subsequent cell death in CHP-212 neuroblastoma cells^[1].
CK2-TN03 (0.5 μM; 24 h) arrests CHP-212 neuroblastoma cells in mitosis, blocks successful cell division, and induces mitotic catastrophe and cell death^[1].
CK2-TN03 (0.5 μM; 48 h) downregulates the activity and expression of survivin in CHP-212 neuroblastoma cells by directly inhibiting CK2-mediated phosphorylation of survivin and indirectly altering the AKT1/MDM2/p53 and BRD4/MYCN pathways, without changing the expression of CK2^[1].
CK2-TN03 (0.5 μM; 48 h) does not affect the viability of differentiated quiescent SH-SY5Y neuroblastoma cells, which exhibit low survivin expression levels^[1].
CK2-TN03 (1-10 μM; 72 h) induces cell death in a diverse panel of 160 cancer cell lines, with significant tumor entity selectivity, and exhibits the highest potency against melanoma, lymphoma, lung cancer, neuroblastoma, ovarian cancer, myeloma, soft tissue cancer and osteosarcoma cell lines^[1].
CK2-TN03 (10 μM; 1 h) exhibits excellent permeability in MDCKII-MDR1 cells, with negligible efflux and no P-gp substrate activity^[1].

Apoptosis Analysis^[1]

Cell Line:

Neuroblastoma CHP-212
Concentration:

0.35, 0.5 and 1.0 μM
Incubation Time:

48 h (monitored every 2 h)
Result:

Induced a time-dependent increase in caspase 3/7 activation, with significantly higher activation levels observed from 18 h onward compared to vehicle-treated controls.
Left a fraction of cell death unaffected by cotreatment with pan-caspase inhibitor Q-VD-OPh, while the inhibitor reduced most CK2-TN03-induced cell death.

Cell Cycle Analysis^[1]

Cell Line:

Neuroblastoma CHP-212
Concentration:

0.5 and 1.0 μM
Incubation Time:

24 h, 48 h
Result:

Increased the percentage of cells in the G2/M phase and the subG1 (dead cell) population after 24 and 48 h of treatment, with significant increases observed at both concentrations and time points compared to controls.
Increased G2/M phase cells after 24 h at 0.5 μM and 1.0 μM.
Further elevated G2/M and subG1 populations after 48 h at both concentrations.

Cell Viability Assay^[1]

Cell Line:

Differentiated neuroblastoma SH-SY5Y
Concentration:

0.5 μM
Incubation Time:

48 h
Result:

Did not reduce viability of differentiated SH-SY5Y cells, which had ~20% of the survivin protein levels present in undifferentiated cells.

In Vivo

CK2-TN03 (40 mg/kg; i.p.; once daily; 28 days) significantly reduces neuroblastoma xenograft tumor growth and improves mouse survival, with a subset of mice achieving long-term tumor control or remission^[1].

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

Animal Model:

(Ncr)-Foxn1 nu nude mice (7-8 weeks old)^[1]
Dosage:

40 mg/kg
Administration:

i.p.; once daily; 28 days
Result:

Reduced tumor growth rate, with tumor volume relative to baseline (VTx/VT0) reaching ~6 on day 28, compared to ~9 in vehicle controls.
Improved mouse survival: 5 treated mice survived to day 49, compared to 1 vehicle-treated mouse; 2 treated mice survived beyond day 85, with one showing complete tumor remission by day 14 and the other exhibiting a small, non-growing tumor mass post-treatment.
Increased p53 levels and decreased survivin levels and survivin phosphorylation in tumor tissue.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
