Introduction of 522-51-0 :

Dequalinium chloride is an Apamin (HY-P0256)-sensitive potassium channel selective blocker. Dequalinium chloride is a cationic, lipophilic mitochondrial poison. Dequalinium chloride is also an antagonist pf α7 nAChR, and an anti-microbial antiseptic agent with a broad bactericidal and fungicidal activity[1][2][3][4]. In Vitro: Dequalinium chloride blocks angiotensin II (100 nM)-evoked K+ loss in guinea-pig hepatocytes, with an IC50 of 1.5 μM[5].
Dequalinium (0-100 μg/mL, 72 h) chloride inhibits cell growth in human Pca cell lines (PC3, DU145, LNCaP, MDA-PCA-2B), and induces cell apoptosis in PC3 cells (0.9 μM, 4 h)[7].
In Vivo: Dequalinium chloride shows a LD50 of 18.3 mg/kg in mice (i.p., a single time)[2].
Dequalinium chloride (2 mg/kg, i.p., daily for 10 days) inhibits the tumor growth of mouse bladder carcinoma MB49[3].
Dequalinium chloride (2 mg/kg, s.c.) reduces Diisopropylfluorophosphate-induced tremors (organophosphate poisoning) in mice[6].
