Biological Activity
| Targets | DNA synthesis |
| ln Vitro | After 48 hours of treatment with 100 µM zidovudine (AZT), AZT triphosphate (3'-azido-3'-deoxythymidine-5'-triphosphate) buildup damages mitochondrial tubing in H9c2 cells. Drp1 is upregulated and Opa1 is downregulated when AZT triphosphate builds up. AZT triphosphate has been shown to induce mitochondrial malfunction, elevate cytotoxic reactive oxygen species (ROS) generation, and disrupt the equilibrium of the mitochondrial quality control system in the H9c2 cell model derived from rat embryonic myoblasts [1]. |
| ln Vivo | Low-dose AZT administration to non-obese diabetic/severe combined immunodeficiency (NOD/SCID) mice injected with transduced K562 cells suppressed tumor growth. This novel suicide gene therapy approach can thus be integrated as a safety switch into therapeutic vectors.[2] |
| Enzyme Assay | Acyclovir (ACV) triphosphate and azidothymidine (AZT) triphosphate inhibit the DNA polymerase of human hepatitis B virus (HBV) by 50% at submicromolar concentrations, but no effects of ACV or AZT treatment have been noted on the clinical manifestations of hepatitis B. We synthesized 1-O-octadecyl-sn-glycero-3-phospho-acyclovir (ODG-P-ACV), 1-O-hexadecylpropanediol-3-phospho-acyclovir (HDP-P-ACV), and 1-O-octadecyl-sn-glycero-3-phospho-azidothymidine (ODG-P-AZT), and evaluated their antiviral activity in human hepatoma cells that constitutively produce HBV (2.2.15 cells). ACV and AZT up to 100 microM caused only slight inhibition of HBV replication in 2.2.15 cells. However, HDP-P-ACV and ODG-P-ACV inhibited viral replication by 50% at 0.5 and 6.8 microM, respectively. ODG-P-AZT also showed increased antiviral activity, with a 50% reduction in HBV replication at 2.1 microM. Based on the EC50, HDP-P-ACV, ODG-P-ACV, and ODG-P-AZT were > 200, > 14.7, and > 48 times more active than their free nucleosides in reducing HBV replication in 2.2.15 cells. To evaluate the biochemical basis for the increased antiviral activity, we studied the uptake and metabolism of 1-O-octadecyl-sn-glycero-3-phospho-[3H]acyclovir (ODG-P-[3H]ACV) in HepG2 cells. Cellular uptake of ODG-P-[3H]ACV was found to be substantially greater than that of [3H]ACV, and cellular levels of ACV-mono-, -di-, and -triphosphate were much higher with ODG-P-ACV. ODG-P-[3H]ACV was well absorbed orally. Based on urinary recovery of tritium after oral or parenteral administration of the radiolabeled compounds, oral absorption of ODG-P-ACV in mice was 100% versus 37% for ACV. ODG-P-ACV plasma area under the curve was more than 7-fold greater than that of ACV. Lipid prodrugs of this type may be useful orally in treating viral diseases.[3] |
| Cell Assay | Gene therapy and stem cell transplantation safety could be enhanced by control over the fate of therapeutic cells. Suicide gene therapy uses enzymes that convert prodrugs to cytotoxic entities; however, heterologous moieties with poor kinetics are employed. We describe a novel enzyme/prodrug combination for selectively inducing apoptosis in lentiviral vector-transduced cells. Rationally designed variants of human thymidylate kinase (tmpk) that effectively phosphorylate 3'-azido-3'-deoxythymidine (AZT) were efficiently delivered. Transduced Jurkat cell lines were eliminated by AZT. We demonstrate that this schema targeted both dividing and non-dividing cells, with a novel killing mechanism involving apoptosis induction via disruption of the mitochondrial inner membrane potential and activation of caspase-3. Primary murine and human T cells were also transduced and responded to AZT. [2] |
