Hierarchical Flux‐Protection Engineering Stabilizes Oxidation‐Prone Metabolic Nodes for High‐Level Curcumin Biosynthesis

Advanced Science, EarlyView.
Flux‐protection engineering stabilizes an oxidation‐prone L‐DOPA node in engineered E. coli by combining acid‐adapted chassis evolution, respiratory‐chain modulation, enzyme‐level flux matching, and pH–DO control. Carbon is redirected from oxidative browning to productive biosynthesis, enabling 1075.2 mg/L curcumin and demonstrating transferability to ...

p-Coumaric acid ameliorates ethanol–induced kidney injury by inhibiting inflammatory cytokine production and NF–κB signaling in rats

Asian Pacific Journal of Tropical Biomedicine, 2019
Objective: To examine the effects of p-coumaric acid on ethanol-induced kidney injury in Swiss Wistar rats. Methods: Ethanol (25% v/v) was used to induce nephrotoxicity in rats. p-Coumaric acid was orally administered at 50, 100, or 200 mg/kg body weight.

Heavy Metal Contamination: Impacts From Plants to the Food Chain and Eco‐Friendly Amelioration Strategies

AgriFood: Journal of Agricultural Products for Food, EarlyView.
Heavy metal pollution reduces soil health and threatens food safety by entering plants; however, the use of nanoparticles, biofertilizers, and organic fertilizers such as biochar offers a promising strategy for improvement and sustainable agriculture. ABSTRACT Heavy metal (HM) pollution, resulting from human activities such as mining and the excessive ...

Mechanistic Insights Into Sustainable Catalytic Pyrolysis of Biomass‐Derived Ferulic Acid: The Role of Alumina Regeneration

Chemistry – A European Journal, EarlyView.
Surface‐bound ferulate phenolate complexes undergo styrene‐like polymerization on alumina, yielding a polymeric carbonaceous layer that progressively transforms into polyaromatic carbon domains with concomitant release of aromatic products, while parallel surface‐assisted decarboxylation produces 4‐vinylguaiacol. ABSTRACT A fundamental understanding of

Fermentation‐Induced Modulation of Polyphenolic Contents and Medicinal Activities in Annona squamosa Seeds

Food Chemistry International, EarlyView.
The study compared the medicinal activities of polyphenols from fermented and unfermented seeds of Annona squamosa. The polyphenols were extracted and subjected to standard analysis. The major phenolic components of the fermented polyphenols and the unfermented polyphenols were found to be 4‐hydroxybenzoic and 4‐hydroxyphenylacetic acid, respectively ...

Synthesis and Antiplatelet Activites of Some Derivatives of p-Coumaric Acid [PDF]

Chemistry & Chemical Technology, 2019
The synthesis of new derivatives of p-coumaric acid was carried out through serial reactions, i.e. alkylating, base hydrolysis, catalytic hydrogenation, and Fisher esterification. All reactions except catalytic hydrogenation were conducted by utilizing microwave irradiation from a household microwave oven.

Surface enhanced Raman scattering of trans‐p‐coumaric and syringic acids

Journal of Raman Spectroscopy, 2009
AbstractThe vibrational spectra of trans‐p‐coumaric acid (pCA) and syringic acid (SA) are discussed. The spectral fingerprints of the organic acids observed in the infrared and Raman spectra are assigned to fundamental vibrational wavenumbers supported by quantum chemical computations. The average surface‐enhanced Raman scattering spectra of both acids
