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.

Methyl 4-chlorocinnamate is an aryl chloride that is synthesized by the reaction of methoxyethyl chloride with cinnamic acid derivatives.

Methyl 4-chlorocinnamate reacts with amine groups in proteins to form amides, which are strong inhibitors of protein synthesis. This compound also inhibits the growth of Candida glabrata by inhibiting phosphonates, which are essential for cell division.

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

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

Muscarinic antagonist; bronchodilator
