描述 Dequalinium chloride (DECA), a cationic, lipophilic mitochondrial poison, selectively targets the mitochondrial membrane of certain epithelial carcinoma cells, in which it inhibits cellular energy production. After a single ip administration, we found a maximum tolerated dose of 15 mg/kg and a lethal dose (LD50) of 18.3 mg/kg. Single ip doses of 20 and 25 mg/kg produced > 50% mortality[3]. The compound antagonized M3 mACHRs (M3 muscarinic receptor) with an IC50 of 0.27 μM for dequalinium chloride[4]. Dequalinium chloride (DQC) is an anti-microbial antiseptic agent with a broad bactericidal and fungicidal activity. Vaginal DQC (Fluomizin vaginal tablets) has been shown to have equal clinical efficacy as clindamycin in the treatment of BV(bacterial vaginosis)[5]. Dequalinium chloride inhibits and kills clinical isolates of A. vaginae at concentrations similar to those of clindamycin and lower than those of metronidazole[6].
