It inhibits replication of herpes simplex virus type 1 and 2, varicella zoster virus, and Epstein Barr virus in cell culture. 5-FAU also inhibits HIV replication in vitro and in animal models. The antiviral activity of 5-FAU is due to its inhibition of viral DNA polymerase, which prevents the synthesis of viral DNA from viral RNA templates.</p>

<p>2,4-Dithiothymidine (DT) is a chemotherapeutic that has been shown to be clinically effective in the treatment of hematopoietic malignancies. It is an oligothymidylate analogue that contains a pyrimidine heterocycle and an ethylthio group. DT is not a nucleoside analog, but it inhibits DNA synthesis by binding to the enzyme thymidylate synthase and preventing the formation of thymine from uracil. DT also binds to single-stranded DNA with high affinity and alters its conformation, which may inhibit transcription and replication. The photophysical properties of this molecule are studied theoretically using quantum mechanics and population analysis theory. The reagent DT can be used to focus attention on other molecules or conformation states of proteins that might have improved biological activity.</p>

<p>5'-O-tert-Butyldimethylsilyl-2,2'-anhydrouridine is a modified nucleoside that has been used as an anticancer agent and antiviral and antifungal agent. It has been shown to inhibit the growth of tumor cells in animal models by inhibiting DNA synthesis and repair. 5'-O-tert-Butyldimethylsilyl-2,2'-anhydrouridine is also able to bind to RNA with high affinity, making it a potential candidate for use as an antiviral agent against HIV. This compound does not occur naturally in cells and can be synthesized from other nucleosides.</p>

Flucytosine is an antifungal agent that inhibits the synthesis of DNA by preventing the conversion of deoxyuridine monophosphate to uracil monophosphate. It is used as an antiretroviral therapy in combination with other drugs, such as zidovudine and dideoxyinosine, to treat HIV infections. Flucytosine has been shown to have a strong antitumor response in a model system involving mice with sarcoma 180. This drug can cause serious side effects, including drug interactions and resistance mutations in microorganisms. These side effects are often observed in patients undergoing cancer chemotherapy or immunosuppressive therapy.
