Improved techniques were applied to formulate drugs into dimensional nanostructures, doped "nanovesicles". These nanovesicles are solely composed of self-assembled amphiphilic antiviral agents used for the treatment of viral infections caused by flaviviruses, such as Zika virus. Studies were done to evaluate the effectiveness of the syntheses, formation, and performance under different experimental conditions, and behavior of the drug nanovesicles and . These studies demonstrated that assembling the hydrophobic antiviral drug molecules into nanodrugs is a successful technique for the delivery of the therapeutic agents, otherwise difficult to be supplied. Our studies confirmed that this nanodrug preserved and, in many cases, enhanced the embedded cellular activity of the parental free drug molecules, both and . This proposed formulation is highly important as it addresses the issue of insolubility and low bioavailabiity of a wide range of highly potent pharmaceutical drugs-not limited to a specific class of antiviral drugs-that are of high demand for the treatment of medical conditions and emerging pathogens.

Glycyrrhizic acid (GLA) is the most important bioactive constituent of licorize root and exhibits antiviral, antimicrobial, anti-oxidant, anti-inflammatory, anti-allergic, and antitumor activities. GLA has an amphiphilic nature consisting of two hydrophilic and one hydrophobic part, and its mechanism of action could be mediated by its incorporation into the membrane. Furthermore, GLA presents two different forms, protonated (GLA) and deprotonated (GLAD), and has been suggested that their location inside the membrane could be different.

Unlabelled: Microbial lipopeptides are synthesized by nonribosomal peptide synthetases and are composed of a hydrophobic fatty acid chain and a hydrophilic peptide moiety. These structurally diverse amphiphilic molecules can interact with biological membranes and possess various biological activities, including antiviral properties. This study aimed to evaluate the cytotoxicity and antiviral activity against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) of 15 diverse lipopeptides to understand their structure-activity relationships.

To withstand complex microbial challenges, the mammalian gut largely depends on the secretion of diverse antimicrobial proteins. Type III interferons (IFNλs) are ordinarily considered inducible antiviral cytokines involved in intestinal immunity. Unlike other IFNλs, we found that newly identified IFNλ4 is an intestinal antibacterial protein.

Hepatitis B virus (HBV) infection remains a major health threat with limited treatment options. One of various new antiviral strategies is based on a fusion of nuclease (SN) with the capsid-forming HBV core protein (HBc), termed coreSN. Through co-assembly with wild-type HBc-subunits, the fusion protein is incorporated into HBV nucleocapsids, targeting the nuclease to the encapsidated viral genome.

Influenza virus (IV) infection currently poses a serious and continuing threat to the global public health. Developing effective prevention strategies is important to defend against infection and spread of IV. Here, we developed a triple-protective nanoshield against IV infection in the lungs, formed by self-assembling DSPE-PEG amphiphilic polymers encapsulating the flu-preventive antiviral drug Arbidol internally.
