2,3,4-Triiodo-1H-pyrrole is a model compound that is used to study the reactivity of the functional groups on the molecule. The functional groups include an olefinic group (double bond) and a carbonyl group (single bond). The reactivity of these functional groups depends on their position in the molecule. If they are on adjacent carbon atoms, they will have similar reactivity. This model compound is classified as a reductant because it can be reduced by glutathione and other reductants. It has been shown that 2,3,4-Triiodo-1H-pyrrole can be synthesized from salicylic acid and lead iodide in a reaction with catalytic amounts of sodium borohydride.

Methyl 2-nitropropanoate is a reactive compound that is used as an epigenetic marker. It reacts with lysine residues in proteins and histones, resulting in the methylation of these proteins. Methyl 2-nitropropanoate has been shown to inhibit the replication of DNA and induce cellular apoptosis in mammalian cells. The effector proteins H3K9me2 and H4K5me1 are involved in epigenetic changes that include gene silencing and histone demethylation. Methyl 2-nitropropanoate can also cause clastogenic effects by forming adducts on dna replication enzymes, such as amide and demethylation. Histone lysines are methylated by methyl 2-nitropropanoate, which causes histones to condense into tight bundles of DNA that contribute to the formation of actin filaments.

4-(4-Nitrophenyl)-1H-1,2,3-triazole (NPT) is a bioactive molecule that inhibits the growth of promyelocytic leukemia cells by interfering with the activity of certain enzymes. NPT has been shown to inhibit the influenza virus and human cervical carcinoma cells in vitro. In addition, it has been shown to inhibit the proliferation of leukemia HL60 cells. NPT is an unsymmetrical molecule that forms an imine during the enzymatic process. The molecular modeling studies show that this compound binds to the active site of enzyme histidine kinase in a manner similar to ATP. This binding prevents ATP from forming a stable complex with histidine kinase and phosphorylating its target protein, which disrupts cellular homeostasis and leads to cell death.

Ethynyl(diphenyl)phosphine oxide is an amide that has been shown to be useful in coordination, catalysis, and organic chemistry. It is a conformational analog of the amide group. Ethynyl(diphenyl)phosphine oxide has been used as a hydrogen-bond donor in esterification reactions. This compound can be synthesized by reacting the corresponding boronic acid with ethynyl alcohol. The yields of this reaction are dependent on the temperature and have been found to range from 60% to 70%. The nmr spectra of this compound show two signals at δ 2.95 and δ 4.85 ppm, corresponding to two different conformers of ethynyl(diphenyl)phosphine oxide.

2,4,6-Trimethylphenyl Isothiocyanate is a reactive compound that can inactivate enzymes. It is used as a catalyst and an intermediate in the production of dyes and pharmaceuticals. 2,4,6-Trimethylphenyl Isothiocyanate reacts with dimethyldioxirane to form diphenylphosphine acid. This acid reacts with choline to produce sulfines. The sulfines react with hydrogen to yield the desired product or prodrug. 2,4,6-Trimethylphenyl Isothiocyanate also catalyzes the reaction between sulfur and hydrogen gas at high temperatures to form hydrogen sulfide gas.br>br>
