6-Methoxyindole-2-carboxylic acid methyl ester is a pyrroloquinoline alkaloid with cytotoxic and antiproliferative activities. It inhibits the growth of cancer cells in culture by inducing apoptosis and cell cycle arrest. 6-Methoxyindole-2-carboxylic acid methyl ester has been shown to be effective against breast cancer cell lines in vitro and to inhibit the proliferation of breast cancer cells in vivo. This compound also inhibits the growth of a number of other cancer cell lines such as prostate, colon, lung, liver, stomach, and leukemia. The mechanism of action for this compound is thought to be due to its ability to act as an intramolecular quencher of reactive oxygen species (ROS) or as an inhibitor of DNA synthesis through inhibition of ribonucleotide reductase activity.

3-Acetylindole is a dibenzopyran compound that has been shown to have anti-inflammatory properties. 3-Acetylindole inhibits the acylation reaction of arachidonic acid with coenzyme A and thereby blocks the production of prostaglandin E2. This compound also binds to the benzene ring, which may be due to its acidic nature. 3-Acetylindole has been shown to inhibit T-cell leukemia and other cancers in animal models. It has also been shown to inhibit the growth of cancer cells in culture by blocking DNA synthesis and inhibiting proliferation. The binding constants for this compound have been determined by x-ray crystal structures and protonation studies.

6-Methoxyindole-2-carboxylic acid (6MI) is a potent inhibitor of the enzyme catechol-O-methyltransferase (COMT). This inhibition prevents the conversion of catecholamines, such as dopamine and norepinephrine, to their corresponding methylated products. COMT inhibitors are used clinically to treat Parkinson's disease and other diseases that result from excessive levels of these neurotransmitters. 6MI is also an effective inhibitor of tyrosinase activity in vitro. It has been shown to inhibit the synthesis of melanin by melanocytes and inhibits the production of eumelanin, which is responsible for black or brown skin pigments. The inhibitory potency of 6MI was found to be greater than that for kojic acid, arbutin, and hydroquinone. Optimization studies showed that 6MI was most potent at a concentration of 1 mM and had an IC50 value of 0.3 mM in

4-Nitroimidazole has a redox potential that is well suited to the reduction of nitro groups. It is an antimicrobial agent that inhibits the growth of microorganisms by inhibiting DNA synthesis. 4-Nitroimidazole can be used for the treatment of infectious diseases such as tuberculosis, leprosy, and brucellosis. In rat liver microsomes, 4-nitroimidazole reacts with NADPH to produce a nitro group and an imidazole ring with a new configuration. The reaction mechanism is based on electron transfer from NADPH to the nitro group in 4-nitroimidazole via a series of reactions that involve cytochrome P450 enzymes. This reaction has kinetic energy and matrix effects that affect its pharmacokinetics and pharmacodynamics.

5,12-Dibutylquinacridone is an electron acceptor that is used as a monomer in cationic polymerization. It can be polymerized with acrylates to form polymers that have high fluorescence and photopolymerizable properties. 5,12-Dibutylquinacridone has shown to be reactive with epoxides and diene compounds, which are typically used as monomers in the synthesis of polymers. This chemical has been studied for its use in solar cells and photocurrent generation. The electron spin resonance technique has been used to study the chemical's photophysical properties.
