2'-O-tert-Butyldimethylsilyluridine is a nucleoside that is used in DNA synthesis, antiviral research, and anticancer therapy. It is synthesized from 2'-deoxyuridine monophosphate (2'-dUMP) with the aid of a phosphoramidite coupling agent. It has shown to be an effective activator in the synthesis of oligonucleotides, which are short chains of nucleotide units that can be used for various purposes including the treatment of cancer cells. These chains are synthesized by linking together individual nucleosides with phosphate molecules at each end. The bonds between these phosphate groups and the sugar-phosphate backbone of the nucleotide units are called phosphodiester bonds. This synthetic process can be used to produce DNA or RNA strands as well as modified versions of these strands such as those that have been synthesized with other chemical groups on their sugar-phosphate backbones.

Emtricitabine-d2,15N has shown to reduce viral load significantly in people taking it as part of their treatment regimen.

5-(Furan-2-yl)-2'-deoxyuridine is a novel anticancer drug that is an analog of thymine. 5-(Furan-2-yl)-2'-deoxyuridine inhibits DNA synthesis by inhibiting the formation of deoxythymidylate from uracil and 5-fluorouracil, which in turn prevents the incorporation of thymine into DNA. The drug has been shown to be active against human leukemia cells in culture and to inhibit viral replication in vitro. The drug also blocks RNA synthesis by inhibiting ribonucleotide reductase, preventing the production of nucleosides from nucleotides. 5-(Furan-2-yl)-2'-deoxyuridine has been modified to improve its solubility and stability. This compound is stable for up to 3 months when stored at 4 degrees Celsius and can be used as a starting material for other chemical compounds.
