Benzene with Alkyl Chains Is a Universal Scaffold for Multivalent Virucidal Antivirals

Francesco Stellacci, Heyun Wang, Paulo Henrique Jacob Silva, Matteo Gasbarri, Lixia Wei, Yong Zhu

Most viruses start their invasion by binding to glycoproteins' moieties on the cell surface (heparan sulfate proteoglycans [HSPG] or sialic acid [SA]). Antivirals mimicking these moieties multivalently are known as broad-spectrum multivalent entry inhibito ...

Development of Broad-Spectrum β-Cyclodextrins-Based Nanomaterials Against Influenza Viruses

Francesco Stellacci, Paulo Henrique Jacob Silva, Yong Zhu

In recent decades, epidemics and pandemics have multiplied throughout the world, with viruses generally being the primary responsible agents. Among these, influenza viruses play a key role, as they potentially cause severe respiratory distress, representin ...

A Synthetic Multivalent Lipopeptide Derived from Pam3CSK4 with Irreversible Influenza Inhibition and Immuno-Stimulating Effects

Francesco Stellacci, Li Tang, Bruno Emanuel Ferreira De Sousa Correia, Quy Ong Khac, Francesca Olgiati, Pablo Gainza Cirauqui, Lixia Wei, Armand Kurum, Yong Zhu

The activation of the host adaptive immune system is crucial for eliminating viruses. However, influenza infection often suppresses the innate immune response that precedes adaptive immunity, and the adaptive immune responses are typically delayed. Dendrit ...

Multivalent Virucidal Antivirals: Synthesis, Mechanisms of Action, and Immune-stimulating Effects

Yong Zhu

Viruses initiate invasion by binding to cell surface glycoproteins. Materials mimicking the carbohydrate motifs of these glycoproteins, such as heparan sulfate (HS) and sialic acid (SA) can block viral attachment and inhibit the infection. Multivalent disp ...

Antiviral Mechanism of Virucidal Sialic Acid Modified Cyclodextrin

Francesco Stellacci, Paulo Henrique Jacob Silva, Yong Zhu, Marine Batista, Andrey Sysoev

We have reported that CD-6'SLN [6-sialyllactosamine (6'SLN)-modified beta-cyclodextrin (CD)] can be a potential anti-influenza drug because it irreversibly deactivates virions. Indeed, in vivo, CD-6'SLN improved mice survival in an H1N1 infection model eve ...

Recycling of Polymerase Chain Reaction (PCR) Kits

Francesco Stellacci, Yong Zhu, Weina Liu

Polymerase chain reaction (PCR) kits have been used as common diagnosing tools during the outbreak of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, with daily worldwide usage in the millions. It is well known that at the beginn ...

Non-Toxic Virucidal Macromolecules Show High Efficacy Against Influenza Virus Ex Vivo and In Vivo

Francesco Stellacci, Özgün Kocabiyik, Paulo Henrique Jacob Silva, Valeria Cagno, Yong Zhu, Chiara Medaglia

Influenza is one of the most widespread viral infections worldwide and represents a major public health problem. The risk that one of the next pandemics is caused by an influenza strain is high. It is important to develop broad-spectrum influenza antiviral ...
