Methyl 4-hydroxy-3-methoxycinnamate is a natural phenolic compound that is found in small quantities in many plants and foods. It is used to produce other compounds, such as vanillin, which are used as flavoring agents. Methyl 4-hydroxy-3-methoxycinnamate can be quantified using the enzymatic reaction of peroxidase with 3,4,5-trimethoxybenzene. The kinetics of this reaction have been studied by titration calorimetry. Aspergillus niger catalase has been shown to be sensitive to methyl 4-hydroxy-3-methoxycinnamate. Birch and oak wood lignocellulosic biomass can be converted into sugars through a hydrolysis process with methyl 4-hydroxy-3-methoxycinnamate. The carbohydrate content of birch and oak wood was reduced by approximately 60

Ferulic acid is a plant polyphenol that has been shown to induce apoptosis in human leukemia cells and inhibit the production of tumor necrosis factor-α (TNF-α), thereby improving glucose tolerance. Ferulic acid inhibits the mitochondrial membrane potential by binding to the Mcl-1 protein and inducing its degradation, leading to anion radical scavenging. This compound also has significant cytotoxicity in a model system and has been shown to have hypoglycemic effects in animal studies. Ferulic acid also induces cell cycle arrest by inhibiting the expression of cyclin D1, which is involved in regulating the G1 phase of the cell cycle.

Caffeic acid is naturally produced by the metabolism of plants and fungi. Caffeic acid has an antioxidant activity that can be higher than tocopherol in oil-in-water emulsions. Caffeic acid has proven antimicrobial activity against Staphylococcus aureus. In mice, caffeic acid inhibits the enzyme 5-lipoxygenase thus inhibititing the biosynthesis of the inflammatory mediators leukotrienes.

3,5-Dihydroxycinnamic acid is a metabolite of the amino acid tyrosine and an intermediate in the biosynthesis of phenylalanine. It has been shown to have anti-inflammatory properties that may be due to its ability to inhibit prostaglandin synthesis. 3,5-Dihydroxycinnamic acid has also been identified as a carcinogen and is associated with an increased risk of cancer in women. 3,5-Dihydroxycinnamic acid is found in urine samples at concentrations between 2 and 10 µmol/L.

Trans-4-nitrocinnamic acid is an organic compound that is synthesized from 4-hydroxycinnamic acid by nitration with aqueous or alcoholic nitric acid. Trans-4-Nitrocinnamic acid has been shown to inhibit tyrosinase activity in the presence of metal hydroxides, such as copper, zinc, and iron. The reaction mechanism is unclear but may involve an initial protonation of the phenolic group followed by an electron transfer to the nitro group. This reaction results in an irreversible inhibition of tyrosinase activity. Trans-4-Nitrocinnamic acid also reacts with hydrochloric acid to produce a carboxylate salt that can be used for sample preparation.
