AZT triphosphate TFA (3'-Azido-3'-deoxythymidine-5'-triphosphate TFA) is a active triphosphate metabolite of Zidovudine (AZT). AZT triphosphate TFA exhibits antiretroviral activity and inhibits replication of HIV. AZT triphosphate TFA also inhibits the DNA polymerase of HBV. AZT triphosphate TFA activates the mitochondria-mediated apoptosis pathway[1][2][3]. Treatment with 100 μM Zidovudine (AZT) for 48h disrupts the mitochondrial tubular network via accumulation of AZT triphosphate (AZT-TP) in H9c2 cells. AZT triphosphate accumulation causes downregulation of Opa1 and upregulation of Drp1. AZT triphosphate causes mitochondrial dysfunction, increases the production of cytotoxic reactive oxygen species (ROS), and impairs the balance of the mitochondrial quality control system in H9c2 cell model established from rat embryonic myoblasts[1].

Tenofovir diphosphate is an inhibitor of HIV reverse transcriptase (Kis = 0.022 and 1.55 μM for RNA and DNA, respectively) and hepatitis B virus (HBV) polymerase (Ki = 0.18 μM). It is selective for these enzymes over DNA polymerase α and β, as well as mitochondrial DNA polymerase γ (Kis = 5.2, 81.7, and 59.5 μM, respectively). Tenofovir diphosphate is formed intracellularly through phosphorylation of the prodrugs tenofovir and tenofovir disoproxil by nucleotide kinases. Increased levels of tenofovir diphosphate in isolated peripheral blood mononuclear cells (PBMCs) correlate with a decrease in the risk of simian HIV (SHIV) acquisition in a macaque model of rectal SHIV transmission.

Ribavirin-13C5is intended for use as an internal standard for the quantification of ribavirin by GC- or LC-MS. Ribavirin is an antiviral guanosine nucleoside analog.1,2Upon entry into cells, ribavirin is metabolized to an active triphosphate form that induces viral RNA chain termination and inhibits viral polymerases. It reduces replication in a panel of seven RNA and four DNA viruses in Vero cells (EC50s = 2-95 μg/ml).3Ribavirin also reduces replication of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in Vero cells (EC50= 109.5 μM).4Aerosol administration of ribavirin (30 mg/kg) reduces mortality in a mouse model of influenza A infection.5Formulations containing ribavirin have been used in the treatment of respiratory syncytial virus (RSV), hepatitis C virus (HCV), and viral hemorrhagic fevers. 1.Gilbert, B.E., and Knight, V.Biochemistry and clinical applications of ribavirinAntimicrob.
