Ácidos cinámicos

Syringin analytical standard provided with w/w absolute assay, to be used for quantitative titration.

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.

2-(Trifluoromethyl)cinnamic acid (FTFA) is an organic compound that is used as a pesticide. It has been shown to inhibit the growth of amyloid fibrils, which are thought to contribute to Alzheimer's disease. FTFA is immobilized on different supports and then reacted with l-phenylalanine in order to synthesize the final product. The optimal reaction time is 1 hour at pH 9.5 with sodium carbonate. FTFA can be covalently immobilized on surfaces such as glass, polystyrene, and silicon oxide by reacting it with epoxy groups or amino groups.

Cis-4-Hydroxycinnamic acid is a phenolic acid that is found in plants and is a natural compound. It has been shown to be an inhibitor of cell proliferation. Cis-4-Hydoxycinnamic acid inhibits the synthesis of DNA and RNA, which may inhibit the growth of bacteria and fungi. This compound can be extracted from plant materials by acetate extract or preparative high-performance liquid chromatography (HPLC). Cis-4-Hydoxycinnamic acid also has anti-inflammatory properties, which may be due to its inhibition of prostaglandin synthesis.

Carboxylic acid with phenol function

Ethyl 4-aminocinnamate is a supramolecular, homologous, activated, linear polymer. It is used as an amine and phosphazene ligand in mesomorphic solid-state chemistry. It has a reversible covalent bond that can be thermally broken and re-formed. This property allows for the synthesis of polymers with functional groups on both ends of the molecule. The nitro group on this compound can be reduced to amine to give another functional group. Ethyl 4-aminocinnamate has been shown to have pharmacokinetic properties that are similar to those of ethyl 4-aminobenzoate (EB). EB is an inhibitor of NS5B polymerase that blocks RNA synthesis and leads to inhibition of viral replication. EB also inhibits ring opening reactions in the presence of nitro groups, which may explain its inhibitory effect on HIV RNA synthesis.

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.
