Metabolite Identification
Common NameChlorpheniramine
DescriptionChlorpheniramine, also known as clofeniramina or haynon, belongs to the class of organic compounds known as pheniramines. Pheniramines are compounds containing a pheniramine moiety, which is structurally characterized by the presence of a 2-benzylpyridine linked to an dimethyl(propyl)amine to form a dimethyl[3-phenyl-3-(pyridin-2-yl)propyl]amine skeleton. Chlorpheniramine is a drug. Chlorpheniramine is a very strong basic compound (based on its pKa). In humans, chlorpheniramine is involved in chlorphenamine h1-antihistamine action. Chlorpheniramine is a bitter tasting compound. Chlorpheniramine is a potentially toxic compound. The dextrorotatory stereoisomer, dexchlorpheniramine, has been reported to possess Kd values of 15 nM for the H1 receptor and 1,300 nM for the muscarinic acetylcholine receptors in human brain tissue. The halogenated alkylamine antihistamines all exhibit optical isomerism, and chlorphenamine in the indicated products is racemic chlorphenamine maleate, whereas dexchlorphenamine is the dextrorotary stereoisomer. Chlorphenamine is combined with a narcotic (hydrocodone) in the product Tussionex, which is indicated for treatment of cough and upper respiratory symptoms associated with allergy or cold in adults and children 6 years of age and older. In one example, 4-chlorophenylacetonitrile is reacted with 2-chloropyridine in the presence of sodium amide to form 4-chlorophenyl(2-pyridyl)acetonitrile. It has only weak affinity for the norepinephrine and dopamine transporters (Kd 1,440 nM and 1,060 nM, respectively).

Enzymes

General function:
Involved in monooxygenase activity
Specific function:
Cytochromes P450 are a group of heme-thiolate monooxygenases. In liver microsomes, this enzyme is involved in an NADPH-dependent electron transport pathway. It performs a variety of oxidation reactions (e.g. caffeine 8-oxidation, omeprazole sulphoxidation, midazolam 1'-hydroxylation and midazolam 4-hydroxylation) of structurally unrelated compounds, including steroids, fatty acids, and xenobiotics. Acts as a 1,8-cineole 2-exo-monooxygenase. The enzyme also hydroxylates etoposide.
