Task: Please create a text description for a molecule.
Molecule SMILES: Nc1nc(NC2CC2)c2ncn([C@H]3C=C[C@@H](C(=O)O)C3)c2n1
Constraint: Answer the question with full sentences.
Result: The molecule 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 derives from an abacavir.
