The bound form of 4,4'-Diamino-3,3'-dimethyldiphenylmethane can be detected using an electrode and hydroxyl group as a diode. Multivariate logistic regression was used to determine the relationship between the bound form of 4,4'-Diamino-3,3'-dimethyldiphenylmethane and women who have not had any symptoms of cervical cancer. A section was taken from each subject's cervix and stained with 4,4'-Diamino-3,3'-dimethyldiphenylmethane

3-Methoxy-4-nitrobenzoic acid methyl ester is a dianellidin, a type of natural product. It is an ionizing acid that catalyzes the reaction between carboxylic acids and hydroxyl compounds. This compound is used to produce some drugs, such as methyldopate, which is an antiarrhythmic drug that slows heart rate. The catalytic rate of 3-methoxy-4-nitrobenzoic acid methyl ester can be increased by buffers and solvents (e.g., methanol). These compounds increase the concentration of the reactants in solution and reduce the activation energy required for the reaction to take place. Uncatalyzed reactions are slow because there are no molecules to act as intermediates in the process.

2-Cyanocinnamic acid is a fatty acid that has been shown to inhibit the synthesis of proteins. It binds to cytochrome c oxidase, inhibiting mitochondrial respiration and electron transport, leading to decreased ATP production. 2-Cyanocinnamic acid is not easily transported out of mitochondria, which leads to its accumulation in the mitochondrial matrix. This accumulation causes synergistic inhibition with glutamate, leading to a decrease in ATP production and an increase in intracellular levels of reactive oxygen species (ROS). The use of 2-cyanoacrylic acid as a mitochondrial transport inhibitor has been proposed for the treatment of obesity and diabetes.
2-Cyanocinnamic acid also inhibits fatty acid uptake by binding to the protein translocase at the outer membrane of cells. This binding prevents monomers from entering the cell, where they are broken down by beta oxidation and converted into acetyl-CoA, which can be used for energy production or stored as triglycer

5-Bromovanillin is an antimicrobial agent that inhibits the growth of bacteria by binding to the enzyme vanillin. It is used as a natural compound, in which it can be found in plants and fruits such as Eugenia caryophyllata and Vanilla planifolia. 5-Bromovanillin has been shown to have a potent inhibitory effect on bacterial growth. The inhibitory effect of this compound is due to its ability to coordinate with the vanillin molecule, forming a complex that blocks the reaction mechanism of the enzyme. This complex also reacts with p-hydroxybenzoic acid, which disrupts the cell membrane and causes leakage of cellular contents. 5-Bromovanillin has been studied using surface methodology and electrochemical impedance spectroscopy (EIS). These studies demonstrated that 5-bromovanillin has a high affinity for methanol solvent and inhibitor molecules, which may contribute to its antimicrobial activity.
