Description
MitoBloCK-12 (522-51-0) attenuates mitochondrial protein import (4-10 μM). Discovered in a screen of FDA-approved drugs. Blocks translocation of a mutant form of alanine: glyoxylate aminotransferase (AGT) to the mitochondria and restores AGT trafficking to peroxisomes.1?Also reduces oxalate accumulation and thus has potential to treat patients with primary hyperoxaluria 1 who possess mutations in AGT.1?Also displays antimicrobial activity2, inhibits apamin-sensitive K+?channels3?and induces apoptosis by inhibiting XIAP4.
Chemical Properties
White or yellowish-white powder, hygroscopic.
Uses
antiinfectant, antineoplastic
Uses
Bacteriostat, antiseptic.
Uses
Dequalinium Chloride is a quaternary ammonium cation and the active ingredient in various medications including antiseptic and anti-malarial agents.
Definition
ChEBI: An organic chloride salt that is the dichloride salt of dequalinium.
Manufacturing Process
a) 15 g of 4-aminoquinaldine, 15 g of decamethylene diiodide and 200 ml of
methyl ethyl ketone were refluxed together for 400 hours. The mixture was
allowed to cool, the precipitate filtered off, washed with methyl ethyl ketone,
and 1,1'-decamethylenebis(4-aminoquinaldinium chloride) recrystallized from
ethyl alcohol containing a little methyl alcohol.
b) 160 g of 4-aminoquinaldine, 174 g of decamethylene diiodide and 1,500 ml
of methyl isobutyl carbinol were heated together at 120°C for 90 hours. The
mixture was allowed to cool, the precipitate filtered off, washed with methyl
ethyl ketone and 1,1'-decamethylenebis(4-aminoquinaldinium chloride)
recrystallized from ethyl alcohol containing a little methyl alcohol.

Therapeutic Function
Antiseptic, Antifungal
World Health Organization (WHO)
Skin reactions to dequalinium chloride, including necrotic
lesions, have been reported. It remains available as a mouth and throat disinfectant
in many countries.
General Description
Dequalinium Chloride is a topical bacteriostat that is available as various salts. It is used in wound dressings and mouth infections and may also have antifungal action, but may cause skin ulceration.
Biological Activity
Dequalinium is a quaternary ammonium cation with diverse biological activities. It has antifungal activity against C. albicans, C. glabrata, and C. krusei (MICs = 0.5-2, 64-256, and 128 μg/ml, respectively), antitrichomonal activity against T. vaginalis (MICs = 28.8-230.4 μg/ml), and antibacterial activity against a panel of aerobic and facultative anaerobic bacteria (MICs = 0.25-256 μg/ml). Dequalinium inhibits apamin binding to, and net potassium loss mediated by, SKCa channels in guinea pig hepatocytes stimulated by angiotensin II (Item No. 17150). In vivo, dequalinium (1-10 mg/kg) inhibits primary and recurrent tumor growth in a W163 rat colon carcinoma isograft model.
