Metabolite Identification
Common NameAlosetron
DescriptionAlosetron is a 5-HT3 antagonist used only for the management of severe diarrhoea-predominant irritable bowel syndrome (IBS) in women. Alosetron has an antagonist action on the 5-HT3 receptors and thus may modulate serotonin-sensitive gastrointestinal (GI) processes. Alosetron was voluntarily withdrawn from the US market in November 2000 by the manufacturer due to numerous reports of severe adverse effects including ischemic colitis, severely obstructed or ruptured bowel, and death. In June 2002, the FDA approved a supplemental new drug application allowing the remarketing of the drug under restricted conditions of use.

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.

General function:

Specific function:
Metabolizes several precarcinogens, drugs, and solvents to reactive metabolites. Inactivates a number of drugs and xenobiotics and also bioactivates many xenobiotic substrates to their hepatotoxic or carcinogenic forms.

It oxidizes a variety of structurally unrelated compounds, including steroids, fatty acids, and xenobiotics. Most active in catalyzing 2-hydroxylation. Caffeine is metabolized primarily by cytochrome CYP1A2 in the liver through an initial N3-demethylation. Also acts in the metabolism of aflatoxin B1 and acetaminophen. Participates in the bioactivation of carcinogenic aromatic and heterocyclic amines. Catalizes the N-hydroxylation of heterocyclic amines and the O-deethylation of phenacetin.

General function:
Involved in extracellular ligand-gated ion channel activity
Specific function:
This is one of the several different receptors for 5- hydroxytryptamine (serotonin), a biogenic hormone that functions as a neurotransmitter, a hormone, and a mitogen. This receptor is a ligand-gated ion channel, which when activated causes fast, depolarizing responses in neurons. It is a cation-specific, but otherwise relatively nonselective, ion channel
