Acides cinnamiques

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.

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.

4-Aminocinnamic acid is a monomer that can be polymerized to form polymers. It is soluble in organic solvents and is resistant to UV light. 4-Aminocinnamic acid has been shown to have photochemical properties and can be used to produce hydrogen bonds with other molecules. This compound has been used as a carbon source for microbial growth and has been shown to be an effective genetic control agent for the bacteria Escherichia coli. 4-Aminocinnamic acid has also been shown to inhibit the growth of butyric acid producing bacteria, such as Clostridium butyricum, while promoting the growth of lactic acid producing bacteria, such as Lactobacillus plantarum.

Potassium cinnamate is a white crystalline solid that is soluble in water, ethanol and acetone. It has been shown to be effective for wastewater treatment and can be used as a reducing agent. Potassium cinnamate has been shown to have high values of hydroxide solution, which are often used in the manufacturing of polymers. Potassium cinnamate also exhibits enzyme activities, such as being able to catalyze the oxidation of propionate. This product has been shown to have anti-oxidant properties and can be used for radiation protection. The polymerization of potassium cinnamate leads to polymaleic acid, which is used in the production of plastics.

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.

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.

4-Hydroxy-3-nitrocinnamic acid is a monophenolic compound that contains a reactive residue. It has been shown to have antibacterial and biological properties, which may be due to its ability to inhibit the growth of bacteria. 4-Hydroxy-3-nitrocinnamic acid has also been shown to be an antibiotic, although it is not categorized as one. 4-Hydroxycinnamic acid is a metabolite of this compound, which can be formed in the liver through oxidation by cytochrome P450 enzymes.

4-Acetamidocinnamic acid is a useful building block for many different organic synthesis reactions. It can be used as a reagent, research chemical or specialty chemical, and is often used as a reaction component or intermediate in the synthesis of complex compounds. 4-Acetamidocinnamic acid is also a versatile building block with many applications in organic synthesis. It has been shown to be useful as a scaffold in synthesizing peptides and other bioactive molecules.

Cis-4-Chloro-3-nitrocinnamic acid is an aromatic organic compound with potential utility in biochemical research and synthesis. This compound is typically derived from synthetic chemical processes involving chlorination and nitration reactions on cinnamic acid derivatives. Its molecular structure, characterized by both chloro and nitro functional groups, allows it to interact in unique ways with various biochemical pathways and molecular frameworks.

3,4-Dimethoxy-5-hydroxycinnamic acid is a monoterpenoid indole alkaloid that belongs to the class of biochemical compounds. It is a promiscuous compound and can be found in many plants, such as coffee beans, black pepper, cinnamon, and thyme. 3,4-Dimethoxy-5-hydroxycinnamic acid has been shown to have antimicrobial properties against bacteria and fungi. The metabolomics study showed that this compound may also have anti-inflammatory effects. 3,4-Dimethoxy-5-hydroxycinnamic acid was shown to enhance the transcription of ferulic acid in E. coli cells. This compound was also shown to decrease the levels of transcripts for genes involved in lipid metabolism and fatty acid biosynthesis in human liver cells.
