Abacavir carboxylate is an inactive metabolite of the HIV-1 reverse transcriptase inhibitor abacavir . It is formed from abacavir via reactive aldehyde intermediates that can form adducts with proteins on valine residues.
Abacavir Carboxylate (Abacavir - In House Impurity) is a major metabolite of Abacavir (A105000) in human urine and cerebrospinal fluid (1,2,3).
ChEBI: Abacavir 5'-carboxylic acid is a monocarboxylic acid oxidation product of abacavir, in which the C-5' hydroxymethyl group has been oxidised to a carboxy group. One of the two major metabolites of abacavir in humans (the other is the 5'-glucuronide, CHEBI:64189). It has a role as a metabolite. It is functionally related to an abacavir.
