The Uses of (+)-[3-cyano-3-(3,4-dimethoxyphenyl)hex-6-yl](5,6-dimethoxyphenethyl)methylammonium chloride

R(+)-Verapamil monohydrochloride hydrate has been used as a P-glycoprotein (gp) inhibitor, to detect P-gp expression on the SK-OV-3 and SK-OV-3/DDP cell surface by flow cytometry. It has also been used as a calcium channel blocker, to evaluate its effect on doxorubicin (DOX) cytotoxicity.

Definition

ChEBI: Dexverapamil hydrochloride is a hydrochloride salt resulting from the reaction of equimolar amounts of dexverapamil and hydrogen chloride. It competitively inhibits the multidrug resistance efflux pump P-glycoprotein (MDR-1, EC 3.6.3.44), thereby potentially increasing the effectiveness of a wide range of antineoplastic drugs which are inactivated by MDR-1 mechanisms. Dexverapamil hydrochloride exhibits lower calcium antagonistic activity and toxicity than racemic verapamil hydrochloride. It has a role as an EC 3.6.3.44 (xenobiotic-transporting ATPase) inhibitor. It contains a dexverapamil(1+). It is an enantiomer of a (S)-verapamil hydrochloride.

Biochem/physiol Actions

Verapamil is a calcium channel blocker. Verapamil hydrochloride is a phenyl-alkyl amine derivative and is potentially used for treating hypertension, angina pectoris and arrhythmias. It is water soluble in nature.
