Deciphering the mechanisms of antibacterial and antibiofilm potential of phenolic compounds against Serratia marcescens [PDF]

open access: yesBioresources and Bioprocessing
Biofilm formation significantly contributes to antibiotic resistance in Serratia marcescens, a multidrug-resistant pathogen implicated in persistent respiratory infections. This study investigates the antibacterial and anti-biofilm potential of two plant-

Cinnamic acid and p-coumaric acid are metabolized to 4-hydroxybenzoic acid by Yarrowia lipolytica

open access: yesAMB Express, 2023
Yarrowia lipolytica has been explored as a potential production host for flavonoid synthesis due to its high tolerance to aromatic acids and ability to supply malonyl-CoA.

Poly(Phenol Red)-Based Voltammetric Sensor for the Simultaneous Quantification of Hydroxycinnamic Acids

open access: yesEngineering Proceedings, 2022
Hydroxycinnamic acids are one of the most widely distributed classes of natural phenolics in plants. Their coexistence requires selective methods for quantification.

p-Coumaric acid ? a monomer in the sporopollenin skeleton [PDF]

open access: yesPlanta, 1989
Sporopollenin obtained from wings of Pinus mugo (Turra) pollen was analysed by pyrolysis mass spectrometry. In the spectrum, mass peaks which are characteristic for p-coumaric acid were dominant. p-Coumaric acid was the main degradation compound when the wing material was treated by a gentle method using AII3, and also when the remaining residue of the

In vitro anti-melanoma effect of polyphenolic compounds

open access: yesAsian Pacific Journal of Tropical Biomedicine, 2022
Objective: To evaluate the effects of phenolic acids (caffeic, ferulic, and coumaric acids) and flavones (luteolin and apigenin) on the proliferation and melanogenesis in murine melanoma B16-F10 cells. Methods: Cell proliferation was determined after 24

Ethylene-dependent activity of phenylalanine ammonia-lyase and lignin formation in cucumber roots exposed to phenolic allelochemicals

open access: yesActa Societatis Botanicorum Poloniae, 2014
Seedling roots of cucumber were subjected to allelochemical stress by treating them with 0.1 mM solutions of ferulic, p-coumaric, p-hydroxybenzoic and vanillic acids. In the experiment the influence of derivatives of cinnamic acid (ferulic and p-coumaric

Content of phenolic acids in rye caryopses determined using DAD-HPLC method

open access: yesCzech Journal of Food Sciences, 2001
Phenolic compounds were extracted from rye caryopses with 80% (v/v) methanol. Phenolic acids were determined as free compounds and those liberated from soluble esters and glycosides.

Enhanced lignin monomer production caused by cinnamic Acid and its hydroxylated derivatives inhibits soybean root growth.

open access: yesPLoS ONE, 2013
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.
