Silmitasertib (CX-4945)

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). Phase 1/2.

S6544New

SR-3029

SR-3029 is a potent and selective casein kinase 1δ/1ε (CK1δ/ε) inhibitor with IC50 values of 44 and 260 nM for CK1δ and CK1ε, respectively.

S5265

TBB

TBB (4,5,6,7-tetrabromobenzotriazole) is a selective cell-permeable CK2 inhibitor with IC50 values of 0.9 and 1.6 μM for rat liver and human recombinant CK2 respectively.

S6536New

TTP 22

TTP22 is a casein kinase 2 (CK2) inhibitor with an IC50 value of 100 nM. It displays selectivity for CK2 over JNK3, ROCK1, and MET with no inhibitory effects towards these kinases at 10 μM.

D 4476

D 4476 is a potent, selective, and cell-permeant CK1 (casein kinase 1) inhibitor with IC50 of 200 nM and 300 nM in a cell-free assay for CK1 from Schizosaccharomyces pombe and CK1δ, respectively. Also acts as an ALK5 inhibitor with IC50 of 500 nM.

S8237

IC261

IC261 is a novel inhibitor of CK1. The IC50 of IC261 for CK1 is 16 μM and for Cdk5 is 4.5 mM.

S5516

Ellagic Acid hydrate

Ellagic acid is a potent inhibitor of protein kinase CK2 with IC50s of 0.04, 2.9 and 3.5 μM for CK2, Lyn and PKA respectively. It shows potent antioxidant, anti-mutagenic and antidepressant properties.
