KINETICS, REGULATION AND PURIFICATION OF L-PHENYLALANINE AMMONIA-LYASE FROM GERMINATING LETTUCE SEEDS (PHENYLPROPANOIDS, ENZYME, ALPHA-AMINOXY - BETA-PHENYLPROPIONIC ACID)
… show any inhibition of enzyme activity. Of the phenylpropanoids used, cinnamic acid was found to be a competitive inhibitor whereas chlorogenic acid showed mixed inhibition. Other phenylpropanoid compounds like p-coumaric acid, caffeic acid, coumarin, quercetin, ferulic acid etc. did not show …

Anti-oxidant Action and Anti-aging Activity of Phenylpropanoid Compounds
… between structure and biological activity of phenylpropanoids, we measured effects of phenylpropanoids on anti-oxidant and anti-inflammatory activity and effect of caffeic acid on wound healing in skin-incised mice. Materials & methods: The cinnamic acid derivaties, C_(6)-C₃ compounds, of …

SYNTHESIS OF NATURAL-DERIVED POLYPHENOLS AS POTENTIAL ANTICANCER AGENTS
… directly derived from shikimate pathway, as phenylpropanoids and lignans, or from a mixed biosynthetic pathway (shikimate/ acetate and/or malonate pathways), as stilbenoids or flavonoids. My thesis is devoted to the family of polyphenols with the specific goal of synthesize new …

A study of the toxicological properties of propolis samples from Europe and Saudi Arabia and of their biological activity against protozoa
… are related to the three groups: flavonoids, phenylpropanoids and triterpenes.;In total fifteen isolated compounds were obtained as follows: twelve from the UK samples most of which were flavonoids including 3-Acetoxypinobanksin (1), 7-Methoxychrysin (2), Kaempferol (3), Pinocembrin (4), …

Impact of growth stage, supplemental red LED, and salinity stress on the quality and aroma attributes of hydroponic fennel (Foeniculum vulgare Mill.)
… and aroma compounds accumulation, particularly phenylpropanoids such as (E)-anethole ("sweet", "anise"), estragole ("anise", "herbal"), and p-anisaldehyde ("floral", "sweet"). Transcriptome analysis showed upregulation of key genes involved in phenylpropanoid biosynthesis, including eugenol …

Dual-omics approach for 3,4-dihydroisocoumarin characterisation from Hydrangea serrata and isolation of polyketide synthases for heterologous expression in Pseudomonas putida KT2440
… of specialised plant metabolites including phenylpropanoids. The dihydroisocoumarin biosynthesis is assumed to be enhanced by elicitors and mediated by polyketide synthases, like in cases of phenylpropanoid derived phytoalexins. This work includes the treatment of H. serrata Oamacha with …

Elucidation of the Function of Dihydrochalcones in Apple
Dihydrochalcones (DHCs) are specialised metabolites with a limited natural distribution, found in significant amounts in Malus x domestica Borkh. (cultivated apple) and wild Malus species. Among them, M. x domestica accumulates significant amounts of phloridzin, whilst trilobatin and sieboldin are …

Science Based Authentication of Dietary Supplements: Studies on the Chemical Constituents, Analytical Method and Biological Activities of Scutellaria Spp and Pfaffia Paniculata
… two Scutellaria species mentioned above and two phenylpropanoids, as well as one diterpene isolated from T. canadense, were used as markers simultaneously to provide comprehensive analysis for the above mentioned purposes. As part of the efforts of this project, a HPLC/ESI-MSn method was …

Phytochemical investigation and biological activities of Sanicula europaea and Teucrium davaeanum. Isolation and identification of some constituents of Sanicula europaea and Teucrium davaeanum and evaluation of the antioxidant activity of ethanolic extracts of both plants and cytotoxic activity of some isolated compounds
The aim of this research was to investigate the phytochemistry of two species Sanicula europaea and Teucrium davaeanum which are traditionally used in treatment of wounds. Four compounds were isolated from the 80% methanolic extract of S. europaea; bis-(2-ethylhexyl) phthalate (1), palmitic acid …
