<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>Adenine sulfate dihydrate is an important component of the energy-producing process in mitochondria. Adenine sulfate dihydrate is a necessary cofactor for many metabolic reactions, including those that produce ATP and NADH. It has been shown to promote growth factor activity and stimulate cell proliferation. Adenine sulfate dihydrate can be used as a nutrient solution in recombinant protein production, where it is required for the expression of recombinant proteins in E. coli or mammalian cells. This compound also plays an important role in the glycosylation of proteins during their synthesis on ribosomes and may have implications for protein folding and stability.</p>

<p>Isocytosine is a prodrug that has been synthesized with the intramolecular hydrogen on the nitrogen atoms, which makes it more chemically stable. Isocytosine is a reactive molecule, and can react with tautomers to form isocytosine derivatives. Isocytosine contains three hydrogen atoms that are transferable through reactions to other molecules. The chemical stability of isocytosine allows for its use in wastewater treatment. It also has metabolic effects, such as the inhibition of colorectal adenocarcinoma and metabolic disorders. Isocytosine can be used as a model system for studying transfer reactions and reaction mechanisms.</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>1) Non-toxicity: belong to flower-stem dye, easy to biodegrade, no carcinogenic toxicity.</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>
