3-Indolemethanol is a chemical compound that is used for chemiluminescent reaction. It can be used as an experimental model for studying the effects of 3-indolemethanol on murine hepatoma and human osteosarcoma cells in vitro. This compound has been shown to have oral hypoglycemic activity and to inhibit cancer cell growth. 3-Indolemethanol has also been shown to modulate signal pathways, such as the MAPK pathway, which may lead to pro-apoptotic protein activation or inhibition of physiological effects.

Indoline-2-carboxylic acid is a photophysical molecule with an absorption maximum at 518 nm. It has been shown to inhibit the activity of enzymes such as cyclooxygenase, lipoxygenase, and monoamine oxidases. This compound has been found to be effective in the treatment of cancer cells. Indoline-2-carboxylic acid is also used in pharmaceutical preparations, where it binds to enantiomers of other molecules and inhibits their biological activity. Indoline-2-carboxylic acid reacts with hydrochloric acid to form allyl carbonate and amide.

Quinoline 2,4-dicarboxylic acid (QDA) is a novel cytotoxic agent that targets cervical cancer cells. It inhibits the uptake of glucose and other nutrients by cervical cancer cells, leading to cell death through apoptosis. QDA also inhibits the expression of genes involved in cross-linking reactions, which are important for the structural integrity of proteins. This agent has been shown to inhibit the growth of aniline-induced breast cancer cells and glutamate-stimulated PC12 cells. QDA binds to DNA and forms covalent bonds with nucleotide bases, inhibiting DNA synthesis, as well as interfering with protein synthesis and cell division. The QDA mechanism is similar to that of benzoquinolines and estrone sulfate.

4-Imidazoleacetic acid HCl is a fluorescent probe that binds to the α1 subunit of the dinucleotide phosphate (NADH) oxidoreductase. It has been shown to inhibit mitochondrial functions, which may be due to its ability to inhibit the pentose phosphate pathway and reduce reactive oxygen species levels. 4-Imidazoleacetic acid HCl has also shown inhibitory properties against congestive heart failure by acting on the mitochondria and inhibiting energy metabolism. It can also be used as a chemical biology tool for studying protein interactions with NADH dehydrogenase. The x-ray crystal structures have revealed that 4-imidazoleacetic acid HCl binds to the active site of NADH oxidoreductase with an orientation that mimics a substrate molecule. This allows it to bind tightly and disrupt enzyme activity.

5-Bromoisatoic anhydride is a potential anticancer agent that contains nitrogen atoms. It inhibits the growth of cancer cells by binding to the enzyme acetylcholine, which is involved in the production of growth factors. The compound also inhibits the production of malonic acid, which is a metabolic disorder. 5-Bromoisatoic anhydride forms stable complexes with malonic acid and does not cause any adverse effects on normal cells.

Benzo[c]phenanthrene is a polycyclic aromatic hydrocarbon that has been shown to have carcinogenic properties in rats. It is also a potential mutagen and can cause DNA damage by forming intramolecular hydrogen bonds with guanine residues in DNA duplexes. These adducts are detected in tumor cells of rats treated with benzo[c]phenanthrene, as well as in human liver cells and mouse liver tumor cells. Benzo[c]phenanthrene can be activated by cytochrome P450 enzymes to form reactive metabolites, which bind covalently to DNA, proteins, and other cellular macromolecules. Benzo[c]phenanthrene has been shown to cause cancer in mice when given orally or injected into the peritoneal cavity. This chemical has also been found to cause liver cell necrosis in rats, at doses of 25 mg/kg body weight.

4-Iodoisatin is a heterocyclic compound that can be synthesized by cross-coupling reactions. It has been shown to inhibit the production of prostaglandin E2, COX-2 protein, and tumor necrosis factor in mouse macrophages. 4-Iodoisatin also inhibits the production of protein kinase C (PKC) in these cells. 4-Iodoisatin can be modified into a dimer form with many different substitutions on the ring structure and this modification increases its potency as an inhibitor of PKC. Irradiation can decompose the compound into a single isomer that is more potent than either of the two isomers. This drug may have therapeutic potential for treatment of cancer, arthritis, and other inflammatory disorders.

6-Fluoroindole-3-carboxaldehyde (6FLA) is a synthetic compound that inhibits biosynthesis of the phytoalexins salicylic acid and lignin in plants. It also inhibits the β-glucuronidase enzyme, which hydrolyzes the glucuronide conjugates of phenolic compounds and xenobiotics. 6FLA has been shown to cause mild liver damage in rats, but its effects on humans are unknown. 6FLA may be used as a detectable substance for assays.
