trans-Cinnamaldehyde and trans-cinnamic alcohol have been commonly reported to cause allergic contact dermatitis (ACD) in humans. Cinnamaldehyde is a more potent skin sensitizer than cinnamic alcohol. It has been hypothesized that cinnamic alcohol is a "prohapten" that requires metabolic activation, presumably by oxidoreductase enzymes such as alcohol ...

THE MICROBIAL METABOLISM OF CINNAMIC ACID
Canadian Journal of Microbiology, 1964A strain of Pseudomanas isolated from soil with cinnamic acid as a sole carbon source was found to be simultaneously adapted to the utilization of cinnamic acid and phenylpropionic acid. During growth on either of these compounds, o-hydroxyphenylpropionic acid and 2,3-dihydroxyphenylpropionic acid were produced in the culture medium. The organism, when

The oxidative cyclization reaction of 2-aryl cinnamates and derivatives thereof can be easily performed with MoCl5 as the oxidant. This powerful reagent allows oxidative coupling reactions for which other reagents fail. The best results are obtained when

The cinnamate/monolignol pathway
Phytochemistry Reviews, 2009The cinnamate/monolignol pathway provides precursors for various phenylpropanoid compounds including lignins, lignans, neolignans, p-hydroxycinnamate esters, coumarins, suberins, flavonoids, stilbenes and so on. Therefore, the pathway plays the central role in plant secondary metabolism.

High-yield synthesis of bioactive ethyl cinnamate by enzymatic esterification of cinnamic acid
Food Chemistry, 2016In this paper, Lipozyme TLIM-catalyzed synthesis of ethyl cinnamate through esterification of cinnamic acid with ethanol was studied. In order to increase the yield of ethyl cinnamate, several media, including acetone, isooctane, DMSO and solvent-free medium, were investigated in this reaction.

Absorption and emission properties of the hydroxy-, nitro-, and fluoro-group substituted at the ortho-, meta-, and para-positions of cinnamic acids (1A–9A) and cinnamates (1E–9E) were investigated using the density functional theory (DFT) and time ...
