Metabolite Identification
Common NameCarbovir Triphosphate
DescriptionCarbovir Triphosphate, also known as CBV-TP, belongs to the class of organic compounds known as nucleoside and nucleotide analogues. These are analogues of nucleosides and nucleotides. These include phosphonated nucleosides, C-glycosylated nucleoside bases, analogues where the sugar unit is a pyranose, and carbocyclic nucleosides, among others. Carbovir Triphosphate is a moderately basic compound (based on its pKa). The organic triphosphate that is the 5'-triphosphate of (-)-carbovir. In humans, carbovir triphosphate is involved in abacavir action pathway.
