Vera Muccilli graduated in Industrial Chemistry in 2002 from University of Catania with summa cum laude. In 2006 she obtained a PhD in Chemical Sciences from the same University with a thesis on the application of mass spectrometry to the characterization cereal proteins. During the PhD course she worked for some months in Centro Nacional de Biotenologìa, Unidad de Analisis Estructural de Proteinas, Campus de la UAM, Cantoblanco, Madrid-ES focusing her research on the quantification of gluten proteins in celiac foods. In 2006 the Italian Chemical Society - Mass Spectrometry Division awarded her as young researcher in mass spectrometry. She has collaborated with Consorzio di Ricerca G.P. Ballatore, Raddusa (Catania), CREA-ACM Acireale, (Catania) and with Azienda Ospedaliera Universitaria-Policlinico Vittorio Emanuele Catania. In 2008, 2011, 2012 she was lecturer of the II level Master in “Methodologies in Mass Spectrometry and Applications” and in 2014 she was lecturer of mass spectrometric application for a training course organized by the University of Palermo. Between 2011-2013 she was research fellow at the University of Catania with a project on proteomic investigation of cereal allergens. In June 2015 she received her Postgraduate Specialization Degree in Clinical Biochemistry from the Faculty of Medicine, University of Catania. Since January 2015 she has been Researcher of Organic Chemistry (fixed term contract) at the University of Catania. Her scientific production is documented by papers published in peer-reviewed international journals and communications presented at national and international conferences.

Research activity

Dr. Vera Muccilli is carrying out her research within the programs developed by the Chemistry of Bioactive Natural Products Group.  The research has recently been focused on natural polyphenols, notably because of their antioxidant properties, based on Radical Scavenging, that is, the ability to inhibit or slow down the reactions of radical reactive species. Reactive radicals are harmful to cells and are believed to contribute to the ageing process and degenerative diseases such as cancer or Alzheimer's disease.

Dr. Vera Muccilli's research has two different goals:

a) The study of natural polyphenols, and in particular tannins, used as food additives in oenology, therefore totally devoid of toxicity. Recently published research shows for the first time that in addition to antioxidant properties these tannins have the ability to inhibit α-glucosidase, an enzyme involved in glucose uptake. These molecules may therefore have a preventative property against diabetes and as result could potentially be used in dietary supplements, non-prescription drugs (OTCs, over the counter) or cosmetics.

b) The organic synthesis starting from simple natural compounds, by means of enzymes (such as laccase or lipase) in order to obtain new naturally-occurring polyphenols with pharmacological properties. Thus, magnolol-like compounds, present in magnolia extracts with promising biological properties, have recently been prepared: some of these synthesized compounds show a potent anti-diabetic property (inhibition of α-glucosidase) while others have strong antioxidant ones. The studies are continuing, with the aim of obtaining new polyphenols with both anti-diabetic and antitumor properties.
