In Vitro
CX-5011 is a low-nanomolar ATP-competitive CK2 inhibitor that inhibits nCK2, recombinant CK2α, and the V66A/I174A CK2α mutant, with IC50 values of 0.97-2.50 nM[2].
CX-5011 (0.5 μM) is highly selective for CK2, with Gini coefficients of 0.735 (102 kinases) and 0.794 (235 kinases), respectively, and 11 kinases are inhibited by more than 50% at 0.5 μM[2].
CX-5011 (100 nM) significantly reduces CK2-dependent GST-HDGF phosphorylation in C2C12 WT myoblast lysates, while leaving a detectable residual phosphorylation band[3].
CX-5011 (3 μM; 24-48 h) decreases Bin1, CKB, Tubb3, and Pxn levels in C2C12 WT myoblasts, whereas CK2β and DecR1 remain unchanged[3].
CX-5011 impairs myogenic differentiation and cell fusion in primary mouse muscle precursor cells[4].
CX-5011 (2 μM; 2-6 d after transfection; WT proliferating cells 4 d), despite inhibiting CK2 activity, does not affect proliferation or MyoD expression in CK2β-silenced C2C12 myoblasts[4].
CX-5011 inhibits late muscle-specific gene expression in differentiating CK2α′−/− C2C12 myoblasts but does not affect MyoD[4].
CX-5011 is a potent and selective inhibitor of CK2 in cell-free kinase assays[5].
CX-5011 binds to CK2α and CK2α′ in cells with IC50 values of 350 nM and 66 nM, respectively[6].
CX-5011 (4 days) reduces the viability of the tested cancer cell lines after 4 days, with IC50 values ranging from 1.6 to 9.8 μM, among which K-562 and H1299 are the most sensitive (1.6 μM)[2].
CX-5011 (1-10 μM; 48 h) does not significantly reduce MDA-MB-231 cell viability[6].
CX-5011 (1 μM; 5 days) does not reduce the viability of AMO-1 or L363 parental multiple myeloma cells[6].
CX-5011 produces antiproliferative effects across a panel of 16 cancer cell lines and induces apoptosis in BXPC3 cells and G1 phase accumulation in MDA-MB-231 cells[5].

Animal Model:CD1 (male, 3 months of age)[4]
-
Dosage:90 µg per injection in 50 µl saline
-
Administration:intramuscular; starting at 3 d after injury; repeated every 3 d
-
Result:Reduced CK2 activity in regenerating muscles by approximately 70% up to 14 d without affecting expression of CK2 subunits.
At 7 d postinjury, expression of late muscle-specific markers was reduced.
MyoD and myogenin remained unchanged in CX-5011-exposed regenerating mouse muscle at 7 d.
Myofiber growth was impaired, with reduced fiber cross-sectional area in CX-5011-exposed regenerating muscles compared with vehicle-exposed contralateral muscles.
CX-5011-exposed regenerating fibers showed decreased myonuclei content at 14 d.
Inhibited regenerating fiber-type switching, with decreased mature regenerating fibers and persistence of embryonic myosin-heavy-chain-positive immature fibers at both 7 and 14 d postinjury.
At 4 d of regeneration, CX-5011 did not affect general cell proliferation (Ki67-positive nuclei) but reduced the percentage of Ki67-positive myonuclei within the basal lamina and shifted proliferating myonuclei distribution toward fibers with fewer than 3 nuclei.
Total (Pax7-positive) and activated (MyoD-positive) satellite cell numbers were not affected by CX-5011.
