Tetrabromocinnamic Acid (TBCA) is a new class of specific protein kinase CK2 inhibitors .
Protein kinases have been involved in catalyzing the phosphorylation of serine, threonine and tyrosine residues in protein substrates that play dominant roles in controlling nearly all cellular functions. The Ser/Thr-specific protein kinase CK2 has been implicated in signal transduction, gene expression, DNA repair, RNA and protein synthesis. CK2 is invariably elevated in a wide spectrum of tumours .
In vitro: TBCA was a selective, cell-permeable inhibitor of CK2 with an IC50 of 0.11 μM. The Ki value was 77 nM. TBCA showed minimal effect on a panel of 28 other kinases. TBCA induced cell death in Jurkat adult T cell leukemia cells with an DC50 of 7.7 μM . TBCA dose-dependently inhibited platelet aggregation and secretion induced by various agonists including 2-MeSADP, AYPGKF, SFLLRN, and CRP . TBCA also significantly inhibited agonist-induced thromboxane A2 (TxA2) generation and ERK phosphorylation. TBCA significantly inhibited platelet spreading on immobilized fibrinogen surface and clot retraction mediated by integrin αIIbβ3 signaling .
