Dequalinium Chloride (DECA) is a PKC inhibitor with IC50 of 7-18 μM, and also a selective blocker of apamin-sensitive K+ channels with IC50 of 1.1 μM .
Protein kinase C (PKC) is a monomeric Ca2+- and phospholipid-dependent Ser/Thr protein kinases, it plays a critical role in growth factor-activated signaling and malignant transformation .
DECA is an anti-tumor agent and PKC inhibitor. It is selectively accumulated and retained within the mitochondria of carcinoma cells where it blocked mitochondrial enzymes which can then disrupt cellular energy production, eventually resulting in cell death . Dequalinium is a potent inhibitor of apamin-sensitive K+ channels in hepatocytes and of nicotinic responses in skeletal muscle. Dequalinium blocked angiotensin II-evoked K+ loss with an IC50 value of 1.5 μM and also inhibited 125I - monoiodoapamin binding with Ki of 1.1 μM .
DECA, as a mitochondrial poison, is an agent with capable of potentiating the effects of tumor necrosis factor against ovarian cancer cell lines. DECA treatment can prolong animal survival in mice bearing the PA-1 intraperitoneal ovarian carcinoma xenograft. Single agent DECA increased animal survival by 37% whereas human TNF increased survival by 12% in those animals treated 3 days post tumor injection. DECA/TNF enhanced animal survival by 45% in treated animals .
