Metabolite Identification
Common NameNabumetone
DescriptionNabumetone, also known as relafen or relif, belongs to the class of organic compounds known as naphthalenes. Naphthalenes are compounds containing a naphthalene moiety, which consists of two fused benzene rings. Nabumetone is an extremely weak basic (essentially neutral) compound (based on its pKa). In humans, nabumetone is involved in nabumetone action pathway. A methyl ketone that is 2-butanone in which one of the methyl hydrogens at position 4 is replaced by a 6-methoxy-2-naphthyl group. It is shown to have a slightly lower risk of gastrointestinal side effects than most other non-steroidal anti-inflammatory drugs. A prodrug that is converted to the active metabolite, 6-methoxy-2-naphthylacetic acid, following oral administration.

Enzymes

General function:
Involved in peroxidase activity
Specific function:
Part of the host defense system of polymorphonuclear leukocytes. It is responsible for microbicidal activity against a wide range of organisms. In the stimulated PMN, MPO catalyzes the production of hypohalous acids, primarily hypochlorous acid in physiologic situations, and other toxic intermediates that greatly enhance PMN microbicidal activity.

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 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.
