Ácidos Cinâmicos

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.

The 2-methylcinnamic acid is a derivative of cinnamic acid. It is an organic compound that is a colorless liquid at room temperature. The 2-methylcinnamic acid can be synthesized via the Suzuki coupling reaction between 2-chlorocinnamic acid and 4-hydroxycinnamic acid in the presence of a ruthenium complex, a diphosphine ligand, and an acidic co-solvent. This organic compound has been shown to inhibit prostaglandin synthesis by interacting with the prostanoid receptor, a protein located on the surface of cells that binds to inflammatory agents or hormones. These interactions may also lead to the inhibition of cyclooxygenase (COX) enzymes, which are responsible for prostaglandin synthesis. The 2-methylcinnamic acid can also be converted into flavonoids such as quercetin and apigenin through oxidation reactions.

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.

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.

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.

3,4,5-Tricaffeoylquinic acid is a caffeoylquinic acid derivative that exerts an inhibitory effect on the Toll-like receptor. It also has anti-inflammatory properties. 3,4,5-Tricaffeoylquinic acid has been shown to exhibit strong antiviral and antibacterial activity against infectious diseases such as influenza and tuberculosis. The compound has also been used as a natural dye for food products and cosmetics. 3,4,5-Tricaffeoylquinic acid is used in vitro assays for the identification of compounds with potential antioxidant activity. This compound is also used as a matrix effect to determine the bioavailability of other drugs in vitro and may be useful in analytical methods for determining benzalkonium chloride levels.
