Metabolite Identification
Common NameEnoxacin
DescriptionEnoxacin, also known as ENX or penetrex, belongs to the class of organic compounds known as naphthyridine carboxylic acids and derivatives. Naphthyridine carboxylic acids and derivatives are compounds containing a naphthyridine moiety, where one of the ring atoms bears a carboxylic acid group. Enoxacin is a drug which is used for the treatment of adults (≥18 years of age) with the following infections caused by susceptible strains of the designated microorganisms: (1) uncomplicated urethral or cervical gonorrhea due to neisseria gonorrhoeae, (2) uncomplicated urinary tract infections (cystitis) due to escherichia coli, staphylococcus epidermidis, or staphylococcus saprophyticus, and (3) complicated urinary tract infections due to escherichia coli, klebsiella pneumoniae, proteus mirabilis, pseudomonas aeruginosa, staphylococcus epidermidis, or enterobacter cloacae. Enoxacin is a very strong basic compound (based on its pKa).

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 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.
