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 monosulfate is an orally active, competitive nucleoside reverse transcriptase inhibitor that effectively inhibits HIV replication. Additionally, it exhibits anticancer properties in prostate cancer cell lines, and has the ability to penetrate the blood-brain-barrier and suppress telomerase activity [1] [2] [3].
ent-Abacavir is an enatiomer of Abacavir. Abacavir is a carbocyclic 2'-deoxyguanosine nucleoside reverse transcriptase inhibitor and an anti-HIV drug used to treat HIV infection. Intracellular enzymes convert Abacavir to its active form, carbovir-triphosphate (CBV-TP), which then selectively inhibits HIV reverse transcriptase by incorporating into viral DNA. Abacavir is metabolized in the liver by uridine diphosphate glucuronyltransferase and alcohol dehydrogenase resulting in inactive glucuronide and carboxylate metabolites, respectively.
(+)-Carbovir triphosphate is an active metabolite of Abacavir. It was used to study the molecular mechanism of inhibition and drug resistance for HIV-1 reverse transcriptase.
