<p>4-(4-Aminophenyl)benzene-1,2-diamine (4-APB) is a neuroprotective agent that has been shown to protect neurons in vitro against oxidative stress and glutamate toxicity. 4-APB also inhibits the uptake of 4-(4-aminophenyl)benzene-1,2-diamine into cells by inhibiting the enzyme responsible for its synthesis. This inhibition leads to a decrease in cellular levels of 4-(4-aminophenyl)benzene-1,2-diamine and an increase in its concentration outside the cell. It has been shown to be effective against human ovarian carcinoma cells and ascitic cancer cells, but not against cisplatin resistant cancer cells. The mechanism of action of this drug is still unknown.</p>

<p>4-Chloro-2H-chromen-2-one is an organic compound that is used as a building block in the synthesis of coumarin derivatives. It undergoes nucleophilic substitution reactions with amines, forming 4-hydroxycoumarin. This reaction is catalyzed by organometallic compounds such as PdCl2 and Cu(OAc)2. Cross-coupling reactions have been shown to be effective for the synthesis of coumarin derivatives. The mechanism of this reaction involves oxidative addition of an organometallic reagent to the carbon atom, followed by elimination of water to form an intermediate epoxide. Deuteration is required for this reaction because hydrogen reacts too rapidly with the organometallic reagents to be useful in the coupling process. 4-Chloro-2H-chromen-2-one has been shown to react with other nucleophiles such as thiols, phenols, and alcohols at</p>

<p>2-(Prop-2-en-1-ylsulfanyl)benzoic acid is a phenyl group that has the ability to form a desorption molecule. It is light resistant and photopolymerizable, which means it can be used in the production of polymers. The alkylthio group on this molecule allows for transfer and gel permeation chromatography. 2-(Prop-2-en-1-ylsulfanyl)benzoic acid also has a vinylic group, which makes it hydrosilylation crosslinkable. This makes it an excellent candidate for copolymerization and hydrosilylation.</p>

<p>4-Dimethylaminomethyl-benzoic acid hydrochloride (4DMABAH) is an antiviral agent that inhibits the replication of human immunodeficiency virus type 1 (HIV-1) by blocking the synthesis of viral DNA. 4DMABAH is a prodrug, which is metabolized to its active form, lamivudine, by esterases in the liver and other tissues. 4DMABAH has been shown to be effective against hepatitis B and C viruses in cell culture studies.</p>
