A swift and facile radiosynthesis of [alpha-32P]-3'-azido-3'-deoxythymidine 5'-triphosphate (AZT triphosphate).
Therapy with 3'-azido-3'-deoxythymidine (AZT, Zidovudine®) has become standard to improve both the quality of life and the survival of patients with acquired immunodeficiency syndrome (AIt)S) and AIDS-related complex (1). Isotopically labeled forms of AZT and its nucleotides are of particular importance in the continuing study of the mechanism of AZT action (2, 3) as well as its pharmacology (4...
متن کاملHuman immunodeficiency virus reverse transcriptase. Substrate and inhibitor kinetics with thymidine 5'-triphosphate and 3'-azido-3'-deoxythymidine 5'-triphosphate.
3'-Azido-3'-deoxythymidine 5'-triphosphate (AZTTP) was an efficient substrate for the human immunodeficiency virus 1 reverse transcriptase. It was incorporated into both homopolymer and defined sequence DNA-primed RNA templates and DNA-primed DNA templates. The substrate and inhibitor kinetics of both AZTTP and dTTP were dependent on the template-primer and reaction conditions used. dTMP was in...
متن کاملA radioimmunoassay for deoxythymidine triphosphate.
T h e intracellular concentrations of deoxyribonucleoside triphosphates are important indicators o f metabolic perturbations in antimetabolite-treated cells. However, their measurement in small cell numbers has often proved to be difficult owing to the simultaneous presence o f 1001000fold concentrations o f the corresponding ribonucleoside triphosphates. Excellent resolution is possible with h...
متن کاملEffects of beta-L-3'-azido-3'-deoxythymidine 5'-triphosphate on host and viral DNA polymerases.
We have previously reported that several beta-L-thymidine analogues including beta-L-3'-azido-3'-deoxythymidine (beta-L-AZT), beta-L-3'-fluoro-2',3'-dideoxythymidine (beta-L-FLT) and beta-L-2', 3'-didehydro-2',3'-dideoxythymidine (beta-L-D4T) did not inhibit HIV replication in human peripheral blood mononuclear (PBM) cells whereas their corresponding beta-D-counterparts are known as potent and ...
متن کاملPhosphorylation of 3'-azido-3'-deoxythymidine and selective interaction of the 5'-triphosphate with human immunodeficiency virus reverse transcriptase.
The thymidine analog 3'-azido-3'-deoxythymidine (BW A509U, azidothymidine) can inhibit human immunodeficiency virus (HIV) replication effectively in the 50-500 nM range [Mitsuya, H., Weinhold, K. J., Furman, P. A., St. Clair, M. H., Nusinoff-Lehrman, S., Gallo, R. C., Bolognesi, D., Barry, D. W. & Broder, S. (1985) Proc. Natl. Acad. Sci. USA 82, 7096-7100]. In contrast, inhibition of the growth...
