Cholesterol chloroformate is also an intermediate for the synthesis of other compounds such as cholesteryl sulfate and dextran sulfate. This compound binds to the Toll-like receptor 4 (TLR4) on cells, triggering an inflammatory response and activating the immune system. Cholesterol chloroformate can be used to study tumor cell growth by inhibiting mitosis in mouse tumors with subcutaneous injections of this agent.

Diazolidinyl urea is a preservative used in cosmetics and pharmaceuticals. It is an antimicrobial agent that causes cell lysis by inhibiting the respiratory synthesis of bacteria. Diazolidinyl urea has been shown to be effective against Gram-positive and Gram-negative bacteria, yeast, and mold. The analytical method for diazolidinyl urea is well established, with detection limits of 0.1 ppm. Diazolidinyl urea is stable under normal conditions, but can be degraded by heat or pH changes. This preservative also inhibits microbial growth by reducing the availability of p-hydroxybenzoic acid (pHBA) and formaldehyde as substrates for bacterial metabolism. Diazolidinyl urea also prevents the formation of biofilms on wet surfaces and exhibits some anti-inflammatory effects.

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

Homogentisic acid gamma-lactone is a synthetic compound that is an inhibitor of the enzyme cytochrome P450. It binds to cytochrome P450 in a competitive manner and inhibits the oxidation of other molecules, such as steroids and fatty acids.

This compound is able to suppress the formation of reactive oxygen species by inhibiting the activity of cytochrome P450. Homogentisic acid gamma-lactone also possesses antifungal properties that may be due to its ability to inhibit the synthesis of ergosterol, which is an important component for fungal cell membranes.

The reaction of 2,3,5-trimethyl-4-nitropyridine 1-oxide with hydrogen peroxide is an example of a peroxide reaction. The HOOH molecule is a nucleophilic and attacks the CNO group. This leads to the formation of a new bond between the oxygen and carbon atoms in the molecule. The oxygen atom then becomes an oxidizing agent, which can react with other molecules in order to form more products. In this reaction, hydrogen peroxide is used as an oxidizing agent to produce chlorine gas, water vapor, and nitric oxide gas. The reaction can be summarized as follows: 2CNO + 3HOOH → 4CO + 2O + 3N2O + 3HO2

It inhibits the production of tyrosinase, which is an enzyme that catalyzes the conversion of tyrosinase to 4-hydroxycinnamic acid. 4-Chlorocinnamic acid also inhibits the growth of Candida glabrata in vitro. The effect on candida is due to its ability to inhibit the production of hydroxyl group and aromatic hydrocarbon, both of which are required for candida's survival. 4-Chlorocinnamic acid binds with aryl halide and neutral ph, preventing it from reacting with other substances.

1-(3,4-Methylenedioxyphenyl) 2-nitropropene (1-MPNP) is a phosphatase inhibitor that is active against gram-negative bacteria by inhibiting enterotoxins and chlamydia. 1-MPNP inhibits the activity of tyrosine phosphatases, which are enzymes that play a major role in bacterial virulence. 1-MPNP competitively inhibits the activity of tyrosine phosphatases and prevents them from catalyzing the hydrolysis of polyphosphate substrates. This inhibition leads to an accumulation of polyphosphates in the bacterial cell membrane, which disrupts its permeability and leads to cell death.
