Virus infection is one of the major threats to human health and can be avoided by minimizing exposure to infectious viruses. Viral clearance of pharmaceutical products and sanitization of skin and mucosal surfaces would reduce such exposures. Even with such care, virus infection does occur, requiring effective treatments by antiviral or virucidal agents. Natural products, in particular ingredients of foods and drinks we normally consume or metabolites present in human body at low concentrations, would have advantage over synthetic drugs as antiviral agents for safety concerns. For this reason, we have been studying natural products for their effects on virus inactivation and growth. Such natural products, which we have been focusing, include gallate derivatives, caffeine present in coffee, caffeic acid present in coffee and various fruits, ascorbic and dehydroascorbic acids and a cell metabolite, arginine. Here we will review our work on antiviral and virucidal activities of these compounds and the mechanism of their antiviral and virucidal effects.

Channel catfish virus (CCV) poses a significant threat to catfish culture. Lack of effective vaccines and antiviral treatments necessitates effective disinfection strategies to mitigate its spread. In vitro trials indicated the virus to be inactivated at high temperatures, but was infectious at 40°C.

Medium-chain antimicrobial lipids are promising antiviral agents to inhibit membrane-enveloped viruses such as African swine fever virus (ASFV) and influenza A virus (IAV) in livestock applications. However, current uses are limited to feed pathogen mitigation due to low aqueous solubility and the development of water-dispersible lipid formulations is needed for broader application usage. In this study, we report a water-dispersible antimicrobial lipid mixture of monoglycerides and lactylates that can inhibit ASFV and IAV and exhibits antiviral properties in drinking water and feed matrices.

Face masks represent a valuable tool to prevent the spreading of airborne viruses; however, they show poor comfort and scarce antiviral efficacy. Zein-based coatings are herein exploited to enhance antiviral performance. Zein functionalization is done through acidifying agents (lactic acid, LA).

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)).

There is merit in investigating novel therapeutic molecules that hit vital targets during the viral infection cycle disrupting the interaction between SARS-CoV-2's spike glycoprotein and the host's angiotensin converting enzyme 2 (ACE2) receptor, potentially offering new avenues for treatment. Accordingly, lipid-based vesicular systems like liposomes or niosomes are frequently utilized to overcome these hurdles. Thus, chemically synthesized compounds were encapsulated within PEGylated bilosomes (PBs) to improve their solubility and intestinal permeability, thereby enhancing their anti-SARS-CoV-2 effectiveness.
