Dequalinium chloride is a selective blocker of apamin-sensitive K+ channels and inhibitor of XIAP (X-linked inhibitor of apoptosis protein). Has been shown to induce cytotoxicity in human acute promyelocytic leukemia NB4 cells through disturbance of mitochondrial function, oxidative stress, and downregulation of Raf/MEK/ERK and PI3K/Akt signaling pathways.

Reduced glutathione and excess free iron within dopaminergic, substantia nigra neurons in Parkinson's disease (PD) can drive accumulation of toxic hydroxyl radicals resulting in sustained oxidative stress and cellular damage. Factors such as brain penetrance and bioavailability have limited the

1,1'-Decamethylenebis-4-aminoquinaldinium diiodide (DECA; dequalinium) is an anti-tumor agent and protein kinase C (PKC) inhibitor whose mechanism of action with PKC is unknown. This study reports that with human PKC alpha, DECA exhibited competitive inhibition (Ki = 11.5 +/- 5 microM)
Mitochondria are considered a primary intracellular site of reactive oxygen species (ROS) generation. Generally, cancer cells with mitochondrial genetic abnormalities (copy number change and mutations) have escalated ROS levels compared to normal cells. Since high levels of ROS can trigger
