Ethyl 4-azidobutanoate is a radiotracer that binds to the DNA of tumor cells. It has been shown to have high binding activity in xenograft models, which is mediated by the interaction between ethyl 4-azidobutanoate and nucleophilic sites on the DNA. This radiotracer also has a high specificity for tumors, with no detectable uptake in other tissues. Ethyl 4-azidobutanoate can be used as a diagnostic agent for detecting and quantifying radiation-induced damage in cells and tissues.

5-(o-Tolyl)tetrazole is a compound that can be synthesized by the reaction of tetrazole with an aldehyde. It has been shown to have high efficiency in the preparation of halides, including chlorides and bromides. 5-(o-Tolyl)tetrazole is also efficient for the synthesis of functional groups, such as methyl tetrazole, ethyl tetrazole, phenyl tetrazole, and substituted phenyl tetrazoles. The cyclic form of 5-(o-tolyl)tetrazole is obtained through irradiation or catalysis.
5-(o-Tolyl)tetrazole can also be used as a ligand in coordination chemistry to generate metal complexes with various metals.

2-(1H-Tetrazol-5-yl)phenol (HTZP) is a fluorescent probe that has been shown to have a high affinity for cancer cells. It binds to the DNA of cancer cells and emits light in the presence of hydrogen peroxide. This process generates a signal with a unique wavelength that can be detected by optical microscopy, flow cytometry, and fluorescence spectroscopy. HTZP has also been shown to bind to alkali metal ions such as Li+, K+, Na+, and Cs+. HTZP is an example of a supramolecular ligand that binds to cisplatin, which inhibits DNA replication and protein synthesis in cancer cells. The binding constants for HTZP are higher than those for cisplatin, suggesting that it may be used as an alternative treatment for cancer.

Benzyne is a reactive intermediate that is formed by the tautomerization of 5-bromo-1,3-dimethylpyridin-2(1H)-one. It is an adduct between a bromine atom and a benzene ring. This compound has been shown to react with electron-rich olefins to form bicyclic compounds called diels-alder adducts. These reactions are often catalyzed by metals, such as palladium or nickel. Benzyne also reacts with triple bonds or other electron rich centers to form benzyne adducts, which are highly reactive and can be used as chemical probes for electron density in molecules.

1-(4-Methoxyphenyl)prop-2-en-1-ol (1MPE) is a model compound that has been shown to inhibit the growth of cancer cells in vitro and in vivo. 1MPE inhibits the activity of human liver enzymes, such as cytochrome P450, which are involved in metabolizing xenobiotics and drugs. 1MPE also binds to the DNA repair enzyme topoisomerase II alpha and inhibits its activity. The binding of 1MPE with this enzyme prevents the relaxation of DNA, leading to cell death by apoptosis. 1MPE has been shown to have toxic effects on rat primary hepatocytes and rat liver microsomes. It also inhibits the growth of CD-1 mice transplanted with human colon tumor cells. In addition, 1MPE is excreted unchanged in urine samples from rats dosed orally with high doses of this drug.

3-(Pyridin-2-yloxy)benzoic acid is an organic compound that belongs to the group of anilides. It has been shown to be toxic to plants by inhibiting their chlorophyll production and by causing phytotoxicity. 3-(Pyridin-2-yloxy)benzoic acid also inhibits the germination of seeds, primarily due to its inhibition of growth hormone activity. 3-(Pyridin-2-yloxy)benzoic acid can be used as a herbicide because it is highly effective against broadleaf plants, but not grasses. This compound is also relatively non-toxic to mammals and birds, but can cause skin irritation in humans.
