Metabolite Identification
Common NameIxabepilone
DescriptionIxabepilone is an epothilone B analog developed by Bristol-Myers Squibb as a cancer drug. On October 16, 2007, the U.S. Food and Drug Administration approved ixabepilone for the treatment of aggressive metastatic or locally advanced breast cancer no longer responding to currently available chemotherapies. Ixabepilone is administered through injection, and will be marketed under the trade name Ixempra. [Wikipedia] Ixabepilone is a semisynthetic analogue of epothilone B. It has a lactone lactam modification that

Chemical Taxonomy
DescriptionThis compound belongs to the class of organic compounds known as epothilones and analogues. These are macrolides consisting of a 16-member lactone ring conjugated at the carbon 16 with a 1-(2-methyl-1,3-thiazol-4-yl)prop-1-en-2-yl group. Some epothilone analogues containing a lactam ring instead of the lactone ring.

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.
