WebbZidovudine or azidothymidine (AZT) is azide analog of deoxythymidine; 3′-azido-3′-deoxythymidine. Compounds that are able to block nucleic acid synthesis such as purine and pyrimidine nucleoside analogs are proven … WebbActually, this pyrimidine derivative seems to have a temperature-sensitive route of entrance, a finding that, along with the evidence that, AZT inhibits its own uptake and its transport into phytohaemagglutinin-stimulated peripheral blood mononuclear cells is upregulated, strongly support the idea that AZT uptake into T-cells is associated with a …

WebbAZT, also called zidovudine (ZDV), is a chemical variation of the natural nucleoside thymidine (dThd) by the addition of an azido group (2). As a variation on dThd, AZT typically will interact with the same enzymes as dThd and will follow the same metabolic pathways in the cell although with radically altered kinetic parameters.
