ATTIVITA DI RICERCA E INTERESSI SCIENTIFICI:
Antonio Francioso ha focalizzato la sua attività di ricerca sulla chimica e biochimica delle sostanze organiche naturali biologicamente attive. Ha studiato in dettaglio le proprietà fotochimiche dello stilbene naturale bioattivo trans-resveratrolo, identificando per la prima volta il prodotto di fotoconversione 2,4,6-triidrossifenantrene. In collaborazione con l’Università dell’Avana (Cuba), ha successivamente valutato il potenziale genotossico di questo fotoprodotto.
Nel corso dei suoi studi, ha collaborato allo sviluppo una nuova formulazione di resveratrolo in associazione a carbossimetil β-D-glucano, migliorandone la stabilità e valutandone l’attività antivirale. Questa ricerca, condotta in collaborazione ha conivolto aziende farmaceutiche e altri gruppi di ricerca e ha portato al deposito di un brevetto e alla pubblicazione di numerosi articoli scientifici su riviste internazionali di rilievo.
Nel 2017-2018, grazie a una borsa post-dottorato Leibniz-DAAD, ha lavorato presso il Leibniz Institute of Plant Biochemistry in Germania, dove ha isolato e caratterizzato dalla pianta Phyllanthus orbicularis proveniente dalla flora tropicale endemica cubana una nuova sostanza naturale fenolica (3’,4’,5,7-tetrahydroxydihydroflavonol-8-C-β-D-glucopyranoside, Fideloside) dimostrandone il potenziale antinfiammatorio. Questa scoperta ha aperto nuove prospettive nello studio degli enzimi coinvolti nella biosintesi di C-glicosidi, composti rari con promettenti caratteristiche farmacologiche e particolari profili farmacocinetici. Qualche anno dopo il Prof. Francioso nell’ambito di un progetto di ricerca sulle sostanze naturali da flora tropicale e sub-tropicale ha isolato e elucidato la struttura chimica di un altro nuovo prodotto naturale (2″,4″,6″-6-C-triacetyl β-D-glucopyranosyl-(2S)-3′,4′,5,7- tetrahydroxyflavan-4-one, Tenelloside) dalle promettenti attività biologiche proveniente dalla pianta Phyllanthus tenellus Roxb. presente a Tenerife nell’arcipelago delle isole Canarie.
Il Prof. Francioso ha inoltre indagato i composti organici volatili secreti da formiche del genere Tapinoma, identificando sostanze iridoidi e chetoni coinvolti nella comunicazione chimica e difesa della specie. Ha caratterizzato il veleno della nuova specie Tapinoma darioi e sintetizzato alcuni dei principi bioattivi presenti nella frazione volatile.
Un'altra importante linea di ricerca portata avanti, si occupa dello studio dei secoiridoidi fenolici dell’olio d’oliva e delle sostanze naturali solforate, con l’obiettivo di identificare intermedi chiave nel metabolismo dello zolfo organico. Questo filone di ricerca nasce con lo scopo di elucidare le vie e gli intermedi chiave nel metabolismo dello zolfo al fine di colmare aspetti ancora poco chiari sulla biochimica di questo elemento fondamentale per numerose funzioni vitali.

Research activity
Antonio Francioso interest in the chemistry and biochemistry of natural products led him to investigate in detail the chemical and photochemical properties of the bioactive natural stilbenoid trans-resveratrol (RSV), in particular its photochemical stability and photochemical reaction mechanisms after UV-light irradiation, identifying for the first time the new photochemical reaction product 2,4,6-trihydroxyphenanthrene (THP). During this project Dr. Francioso moved to Cuba at the "Toxicology" group directed by Prof. Angel Lamar-Sanchez (University of Havana, Cuba) to study the possible toxic effects of this newly characterized resveratrol photoproduct (THP), paying particular attention to the genotoxic risk that this product could pose to human health.
The scientific interest on natural product chemistry brought Prof. Francioso to improve significantly the chemical stability of trans-resveratrol by studying the interactions of this stilbene complexed with a modified natural biopolymer, i.e. carboxymethylated (1,3/1,6)-β-D-glucan (CMG). RSV/CMG association was also evaluated for its biological potential, in particular for its antiviral activity and this new formulation was patented by the research group of Sapienza University of Rome (EP2674155B1). These investigations carried out during the PhD, conceived in full autonomy by Dr. Francioso and conducted in collaboration with different research groups, have been published in high-impact international scientific journals (Org. Chem. 2014,79, 93814; Med. Chem. 2014, 10:237-45;J. Agric. Food Chem. 2014,62:1520–15255; Bioorg. Med. Chem.2015,23: 8, 1671-1683; Antiviral Res. 2015,123, 15-21; Int. J. Mol. Sci. 2017,18(9), 2006; Int. J. Mol. Sci. 2017,18(5), 967; Phytochem. Lett. 2019, 30: 362-366).
Prof. Francioso carried out a scientific project titled: "Metabolomics-based Elucidation of the Bioactive Principles of Endemic Cuban Medicinal Plants” in the context of a Leibniz-DAAD 2017 grant of which he was holder (2017-2018) at the Department of Bioorganic Chemistry of the Leibniz-IPB institute in Halle (Saale), Germany. In collaboration with the group of Prof. Dr. Ludger Wessjohann, Antonio Francioso studied the endemic medicinal tropical flora of Cuba and was able to isolate and fully characterize the chemical structure of a novel bioactive natural compound by means of advanced spectrometric techniques. This novel natural product is the major component of Phyllanthus orbicularis medicinal plant and was tested for its anti-inflammatory capacity showing promising pharmacological potential in human monocytes. The new compound, (2R,3R)-(−)-3’,4´,5,7-tetrahydroxydihydroflavonol-8-C-β-D-glucopyranoside (named Fideloside), is a C-glycosyl dihydroflavonol and its discovery represents a very important outcome in the field of phytochemistry and more in general of natural products chemistry. C-linked glycosides, as well as the enzymes involved in their metabolism (C-glycosyltranferases and C-glycosidases), are extremely rare in nature and absent in human metabolism. These features can confer to the molecule a unique pharmacological profile and possible applications in different fields. These modifications of plant secondary metabolites are biochemically and evolutionally not well studied and characterized. Enzymes involved in C-glycosyl bond formation are very little known and only small amounts of C-glycosides are formed as byproduct of O-glycosylation. The elucidation of this new peculiar product from the Cuban endemic Phyllanthus orbicularis can represent a starting point for the study and characterization of novel enzymes involved in C-glycosyl phenolics biosynthesis (Molecules 2019,24 (15), 2855).
Prof. Francioso focused his scientific interest also on organic compounds from natural sources other than plants. He studied and characterized the chemical structures of Volatile organic compounds (VOCs) present in the secretion of particular ants belonging to the genus Tapinoma (Dolichoderinae). VOCs are essential for chemical communication in social insects. Ants, for instance, represent a compelling model not only to deal with exocrine products and their ecological functions, but also to gain further insights into the biosynthesis of different natural products. In their anal glands, Tapinoma (Formicidae: Dolichoderinae) ants are able to synthesize a series of volatile compounds as “chemical weapons”, including iridoids and saturated and unsaturated ketones crucial in self-defence and communication. The reservoir of the anal gland of the living animals contains the raw poison in the liquid state. By opening this reservoir in water, the leaking poison floats and releases a typical odor, which is perceived even by crushing the living worker, and which is called “smell of Tapinoma”. The venom of the newly discovered species Tapinoma Darioi was recently characterized by Prof. Francioso and the main biologically relevant compounds (cyclopentanoids and iridoids) were identified and synthesized in laboratory.
The research investigations of Dr. Francioso are also addressed to another interesting class of metabolites, i.e. Olive oil phenolic secoiridoids and sulfur-containing compounds. Sulfur natural products can play a crucial role in the metabolism of several organisms and are often involved as markers and/or as principal players in different biological conditions. Antonio Francioso studies non-canonical natural sulfur compounds with the aim to isolate and characterize the chemical structures of novel key intermediates in the metabolism of organic sulfur, such as sulfane-sulfur species (“zero-valent” sulfur, S0) and heterocyclic sulfur and nitrogen containing compounds. The scientific research on the chemical evolution and the biochemistry of organic sulfur is an essential field of research that is still unexpolored with respect to the knowledge acquired on the biochemistry of other main chemical elements of living organisms, i.e. carbon, oxygen and nitrogen. In the current scientific context of biochemistry, it is extremely important to gain deeper insight and better understand the role of organic sulfur in the metabolism of different species, given the important role that this element covers in primary and fundamental functions of living beings.
