Cy5 dyes are used for labeling proteins, nucleic acids in biomolecular imaging and fluorescence analysis.

6-Chloro-1,3-dimethyluracil is a nucleoside analog that has been shown to be cytotoxic in vitro. This compound can be synthesized by reacting naphthalene with a nucleophilic nitrogen source, such as sodium carbonate and chlorinating the resulting product with trifluoroacetic acid. 6-Chloro-1,3-dimethyluracil can also be synthesized by reacting malonic acid with cyclen and uridine in the presence of copper metal. The reaction mechanism is believed to involve photoelectron transfer from the copper metal to the uridine ring.

5-Propyl-2-thiouracil (PTU) is a drug used in the treatment of various types of cancer. It is a chemical analogue of thiouracil, but has a different mechanism of action. PTU inhibits the production of tropomyosin, which leads to inhibition of transcriptional regulation and expression of protein genes. PTU also blocks the hydrogen bond between the amino acid glutamine and deoxyribose phosphate backbone, thereby inhibiting translation. Clinical studies have shown that PTU is effective in treating cardiac hypertrophy, renal proximal tubule cells and clinical nephropathy. The use of PTU as a chemotherapeutic agent for cancer treatment has been limited due to its toxicity to animals.

5-Bromo-6-azauracil is a nucleophilic compound that can be used to treat wastewater. It is also able to lyse cells and has been used as an immobilizing agent. The reactive nature of 5-Bromo-6-azauracil enables it to undergo nucleophilic substitutions with amines, which are present in the cell wall and other biomolecules. This process results in the formation of amide bonds, which leads to the inhibition of protein synthesis. 5-Bromo-6-azauracil has shown inhibitory effects on glucans, which may be due to its ability to form covalent bonds with glucose molecules.

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.

2-Amino-6-bromopurine is a cancer drug that is currently undergoing clinical trials for the treatment of prostate cancer. This drug has shown to be effective in treating prostate cancer cells that are resistant to castration, which are not sensitive to this hormone. 2-Amino-6-bromopurine inhibits DNA polymerase, leading to apoptosis in prostate cancer cells. It also interacts with the thiopurine S-methyltransferase enzyme, which leads to the production of 6-mercaptopurine and 6-thioguanine, which can block DNA synthesis by inhibiting ribonucleotide reductase and thymidylate synthase. 2-Amino-6-bromopurine has been shown to inhibit mutations associated with metastatic castration resistant prostate cancer.
