<p>9-(β-D-xylofuranosyl)guanine (9XG) is a trifluoride. It is an antiviral agent that inhibits the growth of herpes virus, in particular by methylating guanosine to 9-methylguanosine in the viral DNA. 9XG binds to the viral DNA and prevents its replication through the inhibition of RNA synthesis. The drug is active against many different types of viruses and has been shown to be effective against tissue cultures infected with herpes virus. 9XG is synthesized from guanosine and boron trifluoride etherate, which are reacted at -78 degrees Celsius for three days. This yields a mixture of compounds with various peracylation groups, which are then separated by chromatography.</p>

<p>4-Thiouracil is a uridine analog and has been shown to inhibit transcriptional regulation by hydrogen bonding with the dna template. 4-Thiouracil is a prodrug that is converted to its active form, thiouracil, which inhibits DNA synthesis and cell proliferation by inhibiting the enzyme topoisomerase II. This results in the formation of abnormal DNA molecules that are not replicated properly. Thiouracil also has photochemical properties due to its ability to absorb light at wavelengths below 400 nm. The photochemical properties of 4-thiouracil have been studied extensively as models for human tissue culture and the study of cancer cells.</p>

<p>3'-O-Benzyl-2'-Deoxy-5-Trifluoromethyluridine (BDBMU) is a pyrimidine derivative that can be used as an antiviral drug. It inhibits the synthesis of DNA and RNA by inhibiting viral polymerase. BDBMU is a prodrug of uracil, which is converted to the active compound in tissues. The benzoylation reaction produces a fluorine atom at C5, which increases its potency. This drug has been shown to have minimal toxicity in tumor cells and has been used for the treatment of leukemia and other cancers.</p>

<p>(S)-HPMPA is a nucleotide analogue, which is a chemically synthesized compound designed to mimic nucleotides. It acts as both an antiviral and an antitumor agent, sourced primarily through synthetic chemistry involving the modification of naturally occurring nucleotide structures. The mode of action of (S)-HPMPA involves mimicking natural substrates of various viral polymerases and cellular enzymes, thereby inhibiting viral DNA synthesis and disrupting the replication cycle of DNA viruses. Additionally, it can interfere with certain cellular pathways contributing to its antitumor effects.</p>

<p>N7-((2-Hydroxyethoxy)methyl)guanine is a reagent, a complex compound, and a useful intermediate that is used in the manufacture of speciality chemicals. N7-((2-Hydroxyethoxy)methyl)guanine is also a versatile building block that has been shown to be effective in reactions involving the synthesis of N-heterocyclic carbene ligands.</p>

<p>6-Azauracil is a heterocycle with the chemical formula C8H10N2O3. It is approved by the FDA to treat HIV infections and has been shown to have pharmacokinetic properties in humans. 6-Azauracil is structurally similar to uracil, which is found in RNA, but lacks the hydroxyl group on the para position of the heterocyclic ring. The synthesis of this drug was accomplished through acid complex formation with nucleotides and nitrous acid. The compound inhibits replication of retroviruses by competitive inhibition of primer binding. 6-Azauracil has also been shown to be toxic in rats, leading to congestive heart failure and death when administered at high doses. This drug may also act as an anti-inflammatory agent by inhibiting prostaglandin synthesis or platelet aggregation.</p>

<p>N2-Acetyl-O6-diphenylcarbamoylguanine is an amide nucleoside that is a potent antiviral agent. It inhibits the synthesis of viral DNA by inhibiting viral DNA polymerase. N2-Acetyl-O6-diphenylcarbamoylguanine also has reactive functional groups that can react with other molecules, such as human serum albumin, to form conjugates that are more stable and can be used for long periods of time. This nucleoside is synthesized by reacting uridine with chloroacetamide and then reacting the resulting product with diphenylcarbamoyl chloride in the presence of triethylamine. The ring opening reaction leads to the formation of a glycosidic linkage between N2-Acetyl-O6-diphenylcarbamoylguanine and the sugar molecule. This nucleoside has been shown to</p>
