Building Blocks

N-(4-Methylphenyl)benzenesulfonamide is a fluorination agent that has been shown to form a hydrogen bond with the hydroxyl group of tyrosine. This bond leads to the formation of a radical chain reaction and increases the selectivity of N-(4-methylphenyl)benzenesulfonamide for tyrosine over other amino acids, such as phenylalanine. The radical chain reaction is also influenced by the functional group, ortho, and dihedral effects on the amide bond. Experimental results have shown that N-(4-methylphenyl)benzenesulfonamide undergoes a radical chain reaction with tyrosine in organic solvents.

4-Methylbenzylsuccinic acid is a metabolite of benzoic acid and other aromatic compounds. It is a precursor in the biosynthesis of 4-methylphenol, which is used as a biocide in cosmetics, plastics, and textiles. The conversion of 4-methylbenzylsuccinic acid to 4-methylphenol occurs by way of 2 methyl groups that are added to the molecule by sulfate reductase. The enzymes fumarate reductase and sulfide oxidoreductase are involved in the conversion of 4-methylbenzylsuccinic acid to 4-methylphenol. In addition, this compound is converted to an intermediate in the biosynthesis of pyrrole, which can be used as an antioxidant or as a precursor for other molecules.

1-naphthalen-2-ylpropan-1-one is a linear acyl compound that is used in the synthesis of other compounds. It reacts with propanoic acid to form 1,2-diphenylethane. The reaction also produces an acylation product and propanoic acid as a byproduct. This reaction is an example of an acylation reaction, which is the process of adding an organic acid group to a hydrocarbon molecule. The result of this reaction is shown in the diagram below.

5-(4-Methoxy-benzylidene)-thiazolidine-2,4-dione is a drug that binds to the transcription factor NF-κB and prevents its translocation into the nucleus. It is used in the treatment of inflammatory diseases such as rheumatoid arthritis, psoriasis, and Crohn's disease. 5-(4-Methoxy-benzylidene)-thiazolidine-2,4-dione also has hepatoprotective effects by inhibiting oxidative stress and proinflammatory cytokines. This drug can be administered orally or intravenously.

4-(4-Oxo-2-sulfanylidene-1,3-thiazolidin-3-yl)benzoic acid (L-OTSA) is a potent inhibitor of the uptake of potassium ions into cells. It binds to the extracellular surface of the cell membrane and prevents potassium from entering the cell. This results in hyperpolarization of the membrane potential and an increase in spontaneous activity. L-OTSA also induces electrophysiological effects such as increased spontaneous activity, decreased action potential duration, and increased threshold for excitation. L-OTSA has been found to inhibit cellular uptake of potassium ions.

4-Chlorophenyl-1-(3-chloropropyl)piperazine dihydrochloride (PCPP) is a drug that is used in the treatment of Parkinson's disease. It has been shown to be an effective replacement for levodopa, which is the most common treatment for Parkinson's disease and other dopamine-related disorders. PCPP does not have any effect on the levels of dopamine or other neurotransmitters in the brain, but it does inhibit the enzymes that break down dopamine and other neurotransmitters. As a result, PCPP prevents or reduces symptoms of Parkinson's disease and other dopamine-related disorders.
