製品説明 Silmitasertib (CX-4945) is a potent and selective inhibitor of CK2 (casein kinase 2) with IC50 of 1 nM in a cell-free assay, less potent to Flt3, Pim1 and CDK1 (inactive in cell-based assay). Silmitasertib induces autophagy and promotes apoptosis. Phase 1/2.
特性 First clinical inhibitor of CK2.
Targets
CK2 [1]
(Cell-free assay)
1 nM
In Vitro
In vitro CX-4945 is selective for CK2, as it only inhibits 7 of the 238 kinases by more than 90% at concentration of 0.5 μM, which is 500-fold greater than the IC50 of CK2. Although in cell-free systems CX-4945 inhibits FLT3, PIM1, and CDK1 with IC50 of 35 nM, 46 nM, and 56 nM, respectively, CX-4945 treatment at 10 μM is inactive against FLT3, PIM1, and CDK1 in cell-based functional assays. CX-4945 exhibits a broad spectrum of antiproliferative activity, and the breast cancer cell lines displays the widest range of sensitivity to CX-4945 with EC50 of 1.71-20.01 μM. The antiproliferative activity of CX-4945 correlates with CK2α mRNA and protein levels but not the CK2α' catalytic subunit, the regulatory CK2β subunit, and the PI3K/Akt or PTEN mutational status. CX-4945 inhibits PI3K/Akt signaling by directly blocking the phosphorylation of Akt at Serine 129 by CK2 rather than through activation of PTEN. CX-4945 treatment causes reduced phosphorylation of p21 (T145), increased levels of total p21 and p27, and induction of caspase 3/7 activity. CX-4945 treatment induces a G2/M cell-cycle arrest in BT-474 cells and a G1 arrest in BxPC-3 cells. CX-4945 inhibits HUVEC proliferation, migration, and tube formation with IC50 of 5.5 μM, 2 μM, and 4 μM, respectively. Under hypoxic conditions in BT-474 and BxPC-3 cells, CX-4945 treatment prevents downregulation of p53 and pVHL and reduces activation of HIF-1α transcription. [1] CX-4945 potently inhibits endogenous intracellular CK2 activity with IC50 of 0.1 μM in Jurkat cells. [2]
Kinase Assay CK2 Kinase Assay
CX-4945 is added at a volume of 10 μL to a reaction mixture comprising 10 μL of assay dilution buffer (ADB; 20 mM MOPS, pH 7.2, 25 mM β-glycerolphosphate, 5 mM EGTA, 1 mM sodium orthovanadate, and 1 mM dithiothreitol), 10 μL of substrate peptide (RRRDDDSDDD, dissolved in ADB at a concentration of 1 mM), 10 μL of recombinant human CK2 (ααββ-holoenzyme, 25 ng dissolved in ADB). Reactions are initiated by the addition of 10 μL of ATP solution (90% 75 mM MgCl2, 75 μM ATP (final ATP concentration=15 μM) dissolved in ADB; 10% [γ-33P]ATP (stock 1 mCi/100 μL; 3000 Ci/mM and maintained for 10 minutes at 30 °C. The reactions are quenched with 100 μL of 0.75% phosphoric acid and then transferred to and filtered through a phosphocellulose filter plate. After washing each well five times with 0.75% phosphoric acid, the plate is dried under vacuum for 5 minutes and, following the addition of 15 μL of scintillation fluid to each well, the residual radioactivity is measured using a Wallac luminescence counter. The IC50 values are derived from eight concentrations of CX-4945 over a range of 0.0001 μM to 1 μM.

濃度 Dissolved in DMSO, final concentrations ~100 μM
反応時間 4 days
実験の流れ Cells are seeded at a density of 3,000 cells per well 24 hours prior to treatment, in appropriate media, and then treated with various concentrations of CX-4945. Suspensions cells are seeded and treated on the same day. Following 4 days of incubation, Alamar Blue (20 μL, 10% of volume per well) is added and the cells are further incubated at 37 °C for 4-5 hours. Fluorescence with excitation wavelength at 530-560 nm and emission wavelength at 590 nm is measured.

In Vivo
In Vivo Oral administration of CX-4945 at 25 mg/kg or 75 mg/kg twice daily displays potent antitumor activity in the BT-474 model, with TGI of 88% and 97%, respectively, and 2 of 9 animals in each group showing more than 50% reduction in tumor size compared with the initial tumor volume. In the BxPC-3 model, CX-4945 treatment at 75 mg/kg twice daily shows 93% TGI with 3 animals having no evidence of tumor remaining at the end of the treatment period. [1] In PC3 xenograft model, administration of CX-4945 at 25 mg/kg, 50 mg/kg, or 75 mg/kg causes tumor growth inhibition with TGI of 19%, 40%, and 86%, respectively. [2]

投与溶媒調製方法:Take μL DMSOストック溶液に μL PEG300,を加え、完全溶解後μL Tween 80,を加えて完全溶解させた後 μL ddH2O,を加え完全に溶解させます。

投与溶媒調製方法:μL DMSOストック溶液に μL Corn oil,を加え、完全溶解。

注意:1.ストック溶液に沈殿、混濁などがないことをご確認ください;
2.順番通りに溶剤を加えてください。次のステップに進む前に溶液に沈殿、混濁などがないことを確認してから加えてください。ボルテックス、ソニケーション、水浴加熱など物理的な方法で溶解を早めることは可能です。

よくある質問(FAQ)

質問1:
How to reconstitute the compound (S2248) for in vivo uses?

回答
For injection, CX-4945 can be dissolved in 2% DMSO+30% PEG 300+2% Tween 80+ddH2O at 5mg/ml clearly. When making the solution, please dissolve the compound in DMSO clearly first. If it dissolves not readily, please sonicate and warm the solution in water bath at about 45-50℃. Then add PEG and Tween. After they mixed well, dilute with water. For oral gavage, CX-4945 can be dissolved in 1% CMC Na at 30mg/ml as a homogeneous suspension. This is a common formulation for oral gavage, and is convenience to prepare.
