Development of alginate film filled with halloysite-carbon dots for active food packaging.

The development of functional bionanocomposites for active food packaging is of current interest to replace non-biodegradable plastic coatings. In the present work, we report the synthesis of an alginate-based nanocomposite filled with modified halloysite nanotubes (HNTs) to develop coatings with improved barrier properties for food packaging. Firstly, HNTs were chemically modified by the introduction of carbon dots units (CDs) onto their external surface (HNTs-CDs) obtaining a nanomaterial where CDs are uniformly present onto the tubes as verified by morphological investigations, with good UV absorption and antioxidant properties.

HIV-1 Integrase Inhibition Activity by Spiroketals Derived from , an Endemic Plant of Sardinia (Italy) and Corsica (France).

In this work we investigated, for the first time, the effect of (L.) Alavi & Heywood, a Sardinian-Corsican endemic plant, on HIV-1 integrase (IN) activity. The phytochemical analysis of the leaves chloroform extract led us to isolate and characterize three compounds (SPK1, SPK2, and SPK3) belonging to the spiroketals, a group of naturally occurring metabolites of phytochemical relevance with interesting biological properties.

Phytochemical Investigation of : Structural Characterization of New -Coumaroyl Alkylphloroglucinols and Antimicrobial Evaluation against .

Species of Juss., the ninth largest family of flowering plants, are a valuable source of bioactive specialized metabolites. A leading position belongs to phloroglucinol derivatives, thanks to their unusual structural features and biological and pharmacological properties.

Gallomyrtucommulones G and H, New Phloroglucinol Glycosides, from Bioactive Fractions of against Species.

Myrtaceae family is a continuous source of antimicrobial agents. In the search for novel antimicrobial agents against species, bioactive fractions of L., growing in the Sardinia island (Italy) have been investigated.

Chemical Characterization and Anti-HIV-1 Activity Assessment of Iridoids and Flavonols from .

Plants are the everlasting source of a wide spectrum of specialized metabolites, characterized by wide variability in term of chemical structures and different biological properties such antiviral activity. In the search for novel antiviral agents against Human Immunodeficiency Virus type 1 (HIV-1) from plants, the phytochemical investigation of L. led us to isolate and characterize four flavonols glycosides along with nine iridoid glycosides, two of them, and , described for the first time.
