Silmitasertib (CX-4945) Casein Kinase 2 Inhibitor

Kat.-Nr.: S2248

Silmitasertib (CX-4945) ist ein potenter und selektiver Inhibitor von CK2 (Casein Kinase 2) mit einem IC50 von 1 nM in einem zellfreien Assay, obwohl es weniger potent gegen Flt3, Pim1 und CDK1 ist (in zellbasiertem Assay inaktiv). Diese Verbindung induziert Autophagy und fördert apoptosis. Phase 1/2.

Wirkungsmechanismus (Mechanism of Action)

Eigenschaften
First clinical inhibitor of CK2.
Targets/IC50/Ki
CK2
(Cell-free assay)
1 nM
In vitro

Silmitasertib (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 this compound inhibits FLT3, PIM1, and CDK1 with IC50 of 35 nM, 46 nM, and 56 nM, respectively, treatment at 10 μM is inactive against FLT3, PIM1, and CDK1 in cell-based functional assays. It exhibits a broad spectrum of antiproliferative activity, and the breast cancer cell lines displays the widest range of sensitivity to it 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. It inhibits PI3K/Akt signaling by directly blocking the phosphorylation of Akt at Serine 129 by CK2 rather than through activation of PTEN. Treatment with this compound causes reduced phosphorylation of p21 (T145), increased levels of total p21 and p27, and induction of caspase 3/7 activity. It induces a G2/M cell-cycle arrest in BT-474 cells and a G1 arrest in BxPC-3 cells. This compound 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, it prevents downregulation of p53 and pVHL and reduces activation of HIF-1α transcription. It potently inhibits endogenous intracellular CK2 activity with IC50 of 0.1 μM in Jurkat cells.

Kinase-Assay
CK2 Kinase-Assay
Silmitasertib (CX-4945) wird in einem Volumen von 10 μL zu einer Reaktionsmischung gegeben, die 10 μL Assay-Verdünnungspuffer (ADB; 20 mM MOPS, pH 7.2, 25 mM β-Glycerolphosphat, 5 mM EGTA, 1 mM Natriumorthovanadat und 1 mM Dithiothreitol), 10 μL Substratpeptid (RRRDDDSDDD, gelöst in ADB in einer Konzentration von 1 mM) und 10 μL rekombinante humane Casein Kinase (ααββ-Holoenzym, 25 ng gelöst in ADB) enthält. Die Reaktionen werden durch die Zugabe von 10 μL ATP-Lösung (90 % 75 mM MgCl2, 75 μM ATP (endgültige ATP-Konzentration = 15 μM), gelöst in ADB; 10 % [γ-33P]ATP (Stammlösung 1 mCi/100 μL; 3000 Ci/mM) gestartet und 10 Minuten bei 30 °C gehalten. Die Reaktionen werden mit 100 μL 0.75 %iger Phosphorsäure abgestoppt und anschliessend auf eine Phosphozellulose-Filterplatte übertragen und filtriert. Nach fünfmaligem Waschen jeder Vertiefung mit 0.75 %iger Phosphorsäure wird die Platte 5 Minuten unter Vakuum getrocknet und nach Zugabe von 15 μL Szintillationsflüssigkeit zu jeder Vertiefung die verbleibende Radioaktivität mit einem Wallac-Lumineszenzzähler gemessen. Die IC50-Werte für diese Verbindung werden aus acht Konzentrationen über einen Bereich von 0.0001 μM bis 1 μM abgeleitet.
In vivo

Oral administration of Silmitasertib (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, treatment with this compound 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. In PC3 xenograft model, administration of it at 25 mg/kg, 50 mg/kg, or 75 mg/kg causes tumor growth inhibition with TGI of 19%, 40%, and 86%, respectively.

Frage 1:
How to reconstitute it (S2248) for in vivo uses?

Antwort:
For injection, it can be dissolved in 2% DMSO+30% PEG 300+2% Tween 80+ddH2O at 5mg/ml clearly. When making the solution, please dissolve this 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, it 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.
