Insights into Molecular Interactions and Biological Effect of Natural Stilbenoids at the TRPA1 Ion Channel. [PDF]

ChemMedChem
Binding of the natural stilbenoids, isolated from Norway spruce and Scots pine, was analyzed at three known binding sites of transient receptor potential ankyrin 1 (TRPA1) using molecular docking and molecular dynamics (MD) simulations. Furthermore, bias‐force pulling simulations predicted a putative novel binding pocket for the stilbenoids, distinct ...

Scots Pines With Tolerance to Melampsora pinitorqua and Diplodia sapinea Show Distinct Metabolic Profiles. [PDF]

Plant Cell Environ
ABSTRACT Diplodia sapinea causes Diplodia tip blight (DTB) and is recognised as an opportunistic necrotrophic pathogen affecting conifers. While DTB is associated with abiotic stress, the impact of biotic stress in the host on D. sapinea's lifestyle shift is unknown. Observed co‐occurrences of D. sapinea and Melampsora pinitorqua, causing pine twisting

Chemical defence in Norway spruce [Elektronisk resurs]

, 2011
Norway spruce (Picea abies) responds to stress by biosynthesis of chemical substances, which can deter invading insects or pathogens. Some of these substances are volatile and can be emitted to the surroundings while others are accumulated within the ...

LC/MS guided identification of metabolites of different extracts of Cissus quadrangularis

Food Chemistry Advances, 2022
Qualitative and quantitative analysis is very essential to identify the phytochemical constituents present in medicinal plants. In the present study, qualitative and quantitative analyses of a medically important plant, namely Cissus quadrangularis (CQ ...

Lignin from Tree Barks: Chemical Structure and Valorization. [PDF]

ChemSusChem, 2020
Bark for good: Tree barks are low‐cost and abundant lignocellulosic wastes produced by the wood industries. This study concerns the detailed structural characterization of lignin from different tree barks, which will be of great help for the development of efficient conversion technologies of these materials and will aid in their full valorization. The

Tissue‐specific stilbene accumulation is an early response to wounding/grafting as revealed by using spatial and temporal metabolomics

Plant, Cell &Environment, Volume 46, Issue 12, Page 3871-3886, December 2023., 2023
Abstract Grafting is widely used in horticulture. Shortly after grafting, callus tissues appear at the graft interface and the vascular tissues of the scion and rootstock connect. The graft interface contains a complex mix of tissues, we hypothesised that each tissue has its own metabolic response to wounding/grafting and accumulates different ...

White wine phenolics: current methods of analysis

Journal of the Science of Food and Agriculture, Volume 103, Issue 1, Page 7-25, 15 January 2023., 2023
Abstract White wine phenolic analyses are less common in the literature than analyses of red wine phenolics. Analytical techniques for white wine phenolic analyses using spectrophotometric, chromatographic, spectroscopic, and electrochemical methods are reported.

Antibacterial effects of natural compounds on biofilm formation of Streptococcus mutans

Clinical and Experimental Dental Research, Volume 8, Issue 6, Page 1426-1433, December 2022., 2022
Abstract Streptococcus mutans is the main cariogenic pathogen in the oral cavity, considered to contribute toward oral diseases. S. mutans is predominantly entrapped in plaque biofilms. Objectives In this study, we surveyed the antibacterial activity of natural compounds in terms of the biofilm production of S. mutans. Material and Methods We extracted

Passion fruit seed extract protects beta‐amyloid‐induced neuronal cell death in a differentiated human neuroblastoma SH‐SY5Y cell model

Food Science &Nutrition, Volume 10, Issue 5, Page 1461-1468, May 2022., 2022
We investigated the neuroprotective effect of piceatannol and passion fruit seed extract (PFSE) rich in this compound in an Alzheimer's disease (AD) mimic cell model. Both piceatannol and PFSE were found to protect beta‐amyloid‐induced neurite fragmentation in the AD cell model.
