Ethyl 2-(3-nitrophenyl)acetate is an organic compound. It is a chloride channel blocker that has been shown to inhibit the activity of multidrug-resistant proteins (e.g., p-glycoprotein and multidrug resistance protein). The uptake of this drug in cells is limited by its low oral bioavailability and its interaction with aluminium ions. This drug interacts with multidrug-resistance proteins, which are involved in the transport of drugs or toxins out of the cell, by competing for binding sites. Ethyl 2-(3-nitrophenyl)acetate inhibits the catalytic activity of these proteins, leading to a regression in multidrug resistance. It can also inhibit the activity of isoxazoles and alcohols.br>br>/p>

(6-Methoxynaphthalen-2-yl)methanol is a fluorescent probe that reacts with cytosolic proteins. When (6-methoxynaphthalen-2-yl)methanol is incubated with human liver, the rate of reaction increases in proportion to the concentration of cytosolic proteins. This probe can be used to detect changes in the activity of dehydrogenase and aldehyde oxidase enzymes, which are responsible for the metabolism of alcohols and aldehydes. The fluorescence intensity also increases when (6-methoxynaphthalen-2-yl)methanol binds to proteins due to an increase in its chromophore.

3-Phenylpent-4-enoic acid is a natural product that is obtained from the lipophilic fraction of various plant species. It can be synthesized using chemoenzymatic reactions. 3-Phenylpent-4-enoic acid can be used as a chiral chemical intermediate in the synthesis of other compounds, such as olefinic compounds and alkene derivatives. This compound has been shown to have promiscuous reactivity, which is characterized by its ability to catalyze metathesis reactions with high enantiomeric excess. The isolated yield for this reaction was high at 96%.

2-(2-Methylpropyl)butanedioic acid is an uncatalyzed chemical reaction that is used for the treatment of wastewater. It is a chiral compound, which means it has a non-superimposable mirror image. 2-(2-Methylpropyl)butanedioic acid can be synthesized by homochiral reactions, which are reactions that uses only one type of chiral molecule to produce a chiral product. The rate of this reaction is controlled by the concentration of reactants and the temperature at which it occurs. This reaction mechanism involves the formation of an enolate ion from 2-(2-methylpropyl) butanedioic acid, followed by deprotonation to form the conjugated enolate. Leukocyte elastase is an enzyme that breaks down elastin in cells, and this enzyme may be inhibited by gabapentin.
