Reactions of phenolic compounds – a bottomless pit?

F1Prof. Andreas Schieber, University of Bonn, Bonn, Germany will give an introductory talk entitled "Reactions of phenolic compounds – a bottomless pit?".

Phenolic compounds are subject to a plethora of enzymatic and non-enzymatic reactions, which may tremendously alter their chemical, physical, and physiological properties. The oxidation of o-diphenols leads to the formation of quinones, which are electron-deficient compounds that may readily react with nucleophiles, such as thiol or amino groups. At the same time, the quinones may oxidize other phenols including anthocyanins through various mechanisms.

Despite the importance of reactions in plant physiology, food technology, nutrition and toxicology, and an increase in relevant studies during the past two decades, our understanding of the conversions of phenolic compounds is still limited, which is due, among others, to the large chemical heterogeneity of this class of secondary plant metabolites. The presentation will provide an overview of the reactions of phenolics in general and subsequently describe the behavior of quinones and the resulting conversion products in more detail.

Hemisynthesis of anthocyanin phase II metabolites and their characterization by LC-ESI-IMS-QTOF mass spectrometry

Sarah Schmitt Malta Polyphenols 2019Sarah Schmitt will speak about "Hemisynthesis of anthocyanin phase II metabolites and their characterization by LC-ESI-IMS-QTOF mass spectrometry" during the Malta Polyphenols 2019 Congress.

Sarah Schmitt from the University of Bonn, Germany will join the Malta Polyhenols 2019 Congress which will be held on September 30 and October 1st, 2019 in Malta.

Sarah Schmitt highlights: Until today, little is known about the biological activity of the phase II metabolites of anthocyanins. Among other reasons, especially the poor commercial availability and the high prices of the phase II metabolites pose a significant hindrance in the identification and quantification. Therefore, strategies for their synthesis are required, which may include chemical and enzymatic approaches. Novel techniques such as ion mobility mass spectrometry are promising for the analytical characterization of compounds and may serve as a basis in the search for metabolites formed in vivo”.

Phenolic compounds from wine industry by-products: characterization and in vitro bioaccesibility

Ariel Fontana Malta Polyphenols 2019 Congress

Dr. Ariel Fontana will give a presentation entitled "Phenolic compounds from wine industry by-products: characterization and in vitro bioaccesibility".

Malta Polyphenols 2019 Congress welcomes Dr. Ariel Fontana from Universidad Nacional de Cuyo (UNCUYO), Argentina.

Summary of talk: The wine industry generates a large volume of wastes, including those by-products produced before, like pruning residues (canes), and along the winemaking process such as pomaces and stems. The increase of consumers’ concerns about the use of additives in alimentary products and the attention that functional foods have attained in the last years prompted the identification of alternative sources of natural antioxidants. Several compounds present in winemaking by-products such as phenolic compounds have shown health-promoting effects and other biological properties mostly related to their antioxidant characteristics. The characterization of compounds is therefore a necessary step to increase the worth and justify their application in food industries. As well, in vitro gastrointestinal simulation is a valuable tool for investigating the effect of digestion on the phenolic compounds bio-accessibility. This approach contributes to assess the nutritional quality of a bioactive compound while encourages the development of functional foods. This talk will focus on the characterization of phenolics from winemaking by-products of Vitis vinifera L. cv. Malbec and the properties of extracts after in vitro digestion with the aim to establish their bio-accessibility

Influence of juice processing and natural variation in the bioaccessibility of phenolics from grapes and blueberries

Mario-Ferruzzi-Malta Polyphenols 2019

Prof. Mario Ferruzzi will talk about his study on Influence of juice processing and natural variation in the bioaccessibility of phenolics from grapes and blueberries.

The Organizing Committee of Malta Polyphenols 2019 Conference is honored to announce the participation of Prof. Mario Ferruzzi from North Carolina State University, USA.

Summary of Talk: The food matrix is known as a modifier of polyphenol bioavailability.  The matrix itself is influenced by genetics, agronomic conditions as well the ultimate food process chosen for production.  For example, juicing and pasteurization of purple grapes modifies both the food matrix (fractionation, structure) and polyphenol profiles (content) influencing ultimate bioaccessibility of polyphenols for uptake/metabolism by humans or the microbiota.  Additionally, while diversity in content of phenolics is commonly studied in fruit germplasm/breeding populations, variation in phenolic bioaccessibility remains largely unknown.   Exploration of natural diversity of phenolic bioaccessibility in blueberry germplasm is beginning to provide insights into matrix effects and will potentially yield genetic targets for improvement of polyphenol bioavailability from fruit products.

Epigenetic modulation of inflammation and synaptic plasticity by polyphenolic metabolites promotes resilience against stress in mice

Giulio Maria Pasinetti Malta Polyphenols 2019

Prof. Giulio Maria Pasinetti from Icahn School of Medicine at Mount Sinai, USA will join the Malta Polyphenols 2019 Congress and give a presentation entitlled "Epigenetic modulation of inflammation and synaptic plasticity by polyphenolic metabolites promotes resilience against stress in mice".

Summary of presentation: Major depressive disorder is associated with abnormalities in the brain and the immune system. Here, through a high-throughput screening, we identify two phytochemicals, dihydrocaffeic acid (DHCA) and malvidin-3'-O-glucoside (Mal-gluc) that are effective in promoting resilience against psychological stress-induced depression. We discuss the ability of DHCA/Mal-gluc to significantly reduces  depression-like phenotypes in a mouse model of increased systemic inflammation induced by transplantation of hematopoietic progenitor cells from stress-susceptible mice. DHCA reduces pro-inflammatory interleukin 6 (IL-6) generations by inhibiting DNA methylation at the CpG-rich IL-6 sequences introns 1 and 3, while Mal-gluc modulates synaptic plasticity by increasing histone acetylation of the regulatory sequences of the Rac1 gene. This study suggests that polyphenolic metabolites capable of influencing peripheral inflammation and synaptic maladaptation may eventually be implemented as novel therapeutic interventions for promotion of mental health.
