OBJECTIVE: In this study, it was aimed to evaluate the protective efficacy of University Wisconsin (UW) and histidine-tryptophan-ketoglutarate (HTK) preservation solutions enriched with P-coumaric acid ellagic acid.
 MATERIAL AND METHOD
 Thirty-six Wistar albino male rats were divided into equal 6ng groups: (Group 1) UW; 2) UW + P-coumaric; 3) Elagic; 4) HTK ;. 5) P-Coumaric; 6) Elagi...

Biotransformations of capsaicinoids such as capsaicin and 8-nordihydrocapsaicin and phenylpropanoids such as cinnamic acid, p-coumaric acid, caffeic acid, and ferulic acid have been investigated using cultured plant cells. Capsain and 8-nordihydrocapsaicin were converted into the corresponding glycosides which are three glycosides respectively using the cultured cells of Catharanthus roseus. In...
Phenylalanine and tyrosine ammonia-lyases form cinnamic acid and p-coumaric acid, which are precursors of a wide range of aromatic compounds of biotechnological interest. Lack of highly active and specific tyrosine ammonia-lyases has previously been a limitation in metabolic engineering approaches. We therefore identified 22 sequences in silico using synteny information and aiming for sequence ...
BACKGROUND Autotoxicity of cucumber root exudates or decaying residues may be the cause of the soil sickness of cucumber. However, how autotoxins affect soil microbial communities is not yet fully understood. METHODOLOGY/PRINCIPAL FINDINGS The aims of this study were to study the effects of an artificially applied autotoxin of cucumber, p-coumaric acid, on cucumber seedling growth, rhizospher...
As a managed pollinator, the honey bee Apis mellifera is critical to the American agricultural enterprise. Recent colony losses have thus raised concerns; possible explanations for bee decline include nutritional deficiencies and exposures to pesticides and pathogens. We determined that constituents found in honey, including p-coumaric acid, pinocembrin, and pinobanksin 5-methyl ether, specific...
Because certain flavonols and phenolic acids are found in pollen and nectar of most angiosperms, they are routinely ingested by Apis mellifera, the western honey bee. The flavonol quercetin and the phenolic acid p-coumaric acid are known to upregulate detoxification enzymes in adult bees; their presence or absence in the diet may thus affect the toxicity of ingested pesticides. We conducted a s...
The ability of Saccharomyces cerevisiae to catabolize phenolic compounds remains to be fully elucidated. Conversion of coniferyl aldehyde, ferulic acid and p-coumaric acid by S. cerevisiae under aerobic conditions was previously reported. A conversion pathway was also proposed. In the present study, possible enzymes involved in the reported conversion were investigated. Aldehyde dehydrogenase A...
Ammonia-lyase activity for L-phenylalanine, m-hydroxyphenylalanine and L-tyrosine was demonstrated in cell-free extracts ofSporobolomyces roseus. Cultures of this organism converted DL-[ring-14C]phenylalanine and L-[U-14C]tyrosine into the corresponding cinnamic acid. Tracer studies showed that these compounds were further metabolized to [14C]protocatechuic acid. Benzoic acid andp-hydroxybenzoi...
Cinnamic acid and its hydroxylated derivatives (p-coumaric, caffeic, ferulic and sinapic acids) are known allelochemicals that affect the seed germination and root growth of many plant species. Recent studies have indicated that the reduction of root growth by these allelochemicals is associated with premature cell wall lignification. We hypothesized that an influx of these compounds into the p...
