Metabolite Identification

Common Name

Clemastine

Description

Clemastine is only found in individuals that have used or taken this drug. It is an ethanolamine-derivative, first generation histamine H1 antagonist used in hay fever, rhinitis, allergic skin conditions, and pruritus. It causes drowsiness. [PubChem]Clemastine is a selective histamine H1 antagonist and binds to the histamine H1 receptor. This blocks the action of endogenous histamine, which subsequently leads to temporary relief of the negative symptoms brought on by histamine.

Enzymes

Enzyme Details

1. Cytochrome P450 3A4

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.
Gene Name:: CYP3A4
Uniprot ID:: P08684
Molecular weight:: 57255.585

2. Cytochrome P450 2D6

General function:: Involved in monooxygenase activity
Specific function:: Responsible for the metabolism of many drugs and environmental chemicals that it oxidizes. It is involved in the metabolism of drugs such as antiarrhythmics, adrenoceptor antagonists, and tricyclic antidepressants.
Gene Name:: CYP2D6
Uniprot ID:: P10635
Molecular weight:: 55768.94

Enzyme Details

3. Histamine H1 receptor

General function:: Involved in G-protein coupled receptor protein signaling pathway
Specific function:: In peripheral tissues, the H1 subclass of histamine receptors mediates the contraction of smooth muscles, increase in capillary permeability due to contraction of terminal venules, and catecholamine release from adrenal medulla, as well as mediating neurotransmission in the central nervous system
Gene Name:: HRH1
Uniprot ID:: P35367
Molecular weight:: 55783.6
