Metabolite Identification
Common NameXimelagatran
DescriptionXimelagatran, also known as exanta or H 376-95, belongs to the class of organic compounds known as dipeptides. These are organic compounds containing a sequence of exactly two alpha-amino acids joined by a peptide bond. Ximelagatran (Ximelagatran or Exarta, H 376/95) is an anticoagulant that has been investigated extensively as a replacement for warfarin that would overcome the problematic dietary, drug interaction, and monitoring issues associated with warfarin therapy. Ximelagatran is a drug which is used for the treatment of acute deep vein thrombosis. Ximelagatran is a very strong basic compound (based on its pKa). In humans, ximelagatran is involved in ximelagatran action pathway. Ximelagatran is a prodrug, and hence, it requires in vivo conversion to the active agent, melagatran. The activation of ximelagatran is produced in the liver and many other tissues mainly by reactions of dealkylation and dehydroxylation. Ximelagatran is an anticoagulant intended to become a replacement for warfarin by overcoming the dietary restrictions, drug interaction, and monitoring issues associated with the former. Its effect is solely related to the inhibition of thrombin. Ximelagatran was the first member of the drug class of direct thrombin inhibitors that can be taken orally.

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. This enzyme contributes to the wide pharmacokinetics variability of the metabolism of drugs such as S-warfarin, diclofenac, phenytoin, tolbutamide and losartan.
