Compounds simultaneously carrying the monoterpene and coumarin moieties have been tested for cytotoxicity and inhibition of activity against influenza virus A/California/07/09 (H1N1)pdm09. The structure of substituents in the coumarin framework, as well as the structure and the absolute configuration of the monoterpenoid moiety, are shown to significantly influence the anti-influenza activity and cytotoxicity of the compounds under study. The compounds with a bicyclic pinane framework exhibit the highest selectivity indices (the ratios between the cytotoxicity and the active dose). The derivative of (-)-myrtenol 15c, which is characterized by promising activity, low cytotoxicity, and synthetic accessibility, has the greatest potential among this group of compounds. It exhibited the highest activity when added to the infected cell culture at early stages of viral reproduction.

Antibacterial and Anti-Influenza Activities of -Heterocyclic Carbene-Gold Complexes.

Pharmaceuticals (Basel)

December 2024

Department of Life, Health and Environmental Sciences, University of L'Aquila, Piazzale Salvatore Tommasi 1, Blocco 11, Coppito, 67010 L'Aquila, Italy.

Background/objectives: Infectious diseases represent a serious threat due to rising antimicrobial resistance, particularly among multidrug-resistant bacteria and influenza viruses. Metal-based complexes, such as -heterocyclic carbene-gold (NHC-gold) complexes, show promising therapeutic potential due to their ability to inhibit various pathogens.

Methods: Eight NHC-gold complexes were synthesized and tested for antibacterial activity against , , and for anti-influenza activity in lung and bronchial epithelial cells infected with influenza virus A/H1N1.

Viral infections and many other dangerous diseases are accompanied by the development of oxidative stress, which is a consequence of an increase in the level of the reactive oxygen species (ROS). In this regard, the search for effective antioxidants remains highly relevant. We tested fullerenol C(OH) in the context of the connection between its self-assembly in aqueous solutions and cell culture media, antiradical activity, UV cytoprotective action, and antiviral activity against international reference strains of influenza virus A(H1N1)pdm09, A(H3N2), and B subtypes in vitro on the MDCK cell line.

Influenza is a disease of significant morbidity and mortality. The number of anti-influenza drugs is small; many of them stimulate the appearance of resistant strains. This article presents the results of assessing the antiviral activity of 1,2,3-triazole-containing derivatives of alkaloid lupinine for their ability to suppress the reproduction of orthomyxoviruses (influenza viruses: A/Vladivostok/2/09 (H1N1) and A/Almaty/8/98 (H3N2)).

This study focuses on the elucidation of the structure and antiviral properties of six nitrogen-containing compounds including amino acid derivates (1 and 2) and heterocyclic compounds (3-6) isolated from the fruiting bodies of Sarcodon imbricatus, particularly Compound 2, an (S)-2-(hydroxyimino)-3-methylpentanoic acid ethyl ester. Their antiviral effects were tested against influenza A virus (IAV) in A549 cells. Particularly, Compound 2 exhibited significant antiviral activity in post-treatment assays, reducing viral protein expression and inhibiting viral replication with an IC of 14.

The genetic recombination and antigenic variation of influenza viruses may decrease the efficacy of antiviral vaccines, highlighting the imperativeness of developing novel anti-influenza agents. Herein, a series of thiophene-based compounds were designed and synthesized as potent anti-influenza agents. Among them, exhibited an excellent anti-influenza activity (EC, H1N1 = 1.
