Hydroxycinnamic acid; inhibitor of 5-LO and 12-LO enzymes

3,5-Di-tert-butyl-4-hydroxycinnamic acid is a chemical compound that belongs to the group of antihistaminic drugs. It is used as an antiallergic drug and has shown to be effective in treating hay fever and asthma. 3,5-Di-tert-butyl-4-hydroxycinnamic acid has been shown to be metabolised by rat plasma into dimethylformamide, tetrahydrofuran, reactive amides, chlorides and volatile compounds. These metabolites are then excreted via the kidneys or liver. The synthesis of 3,5-Di-tert-butyl-4-hydroxycinnamic acid can be done through a two step process that starts with the reaction of pivalaldehyde with hydrochloric acid followed by hydrogenation with rhodium on charcoal catalyst.

Carboxylic acid with additional oxygen functions

4-Phenylcinnamic acid is a prenylated aromatic compound that is used as a chromatographic stationary phase. It has been shown to inhibit the activity of tyrosinase and thus may be used for the treatment of hyperpigmentation disorders such as melasma. 4-Phenylcinnamic acid interacts with piperidine and inhibits its activity, which may lead to new drug development. Molecular modelling of 4-phenylcinnamic acid has shown that it is possible to introduce functional groups into the molecule, making it more reactive. The introduction of biphenyl derivatives may improve the lipophilicity of this molecule.

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.
