Antiviral activity of lipid-modified remdesivir in comparison to common remdesivir

In new research, scientists evaluated the broad-spectrum antiviral activity of ODBG-P-RVn, an orally available, lipid-modified monophosphate prodrug of the remdesivir parent nucleoside (GS-441524) against viruses that cause diseases of human public health concern, including SARS-CoV-2.

COVID vaccines generate antibodies in saliva

Researchers in the United States and Canada have conducted a study showing that the vaccines developed by Pfizer-BioNTech and Moderna to protect against coronavirus disease 2019 (COVID-19) generate local antibody responses in the salivary gland that are independent of the systemic immune response.

Rosin soap as a potential SARS-CoV-2 disinfectant

In a research paper recently uploaded to the preprint server bioRxiv* by Bell et al. (July 19th, 2021), the potential of rosin soap as a virucide is investigated, finding a ten-thousand-fold drop in infectivity against enveloped viruses such as influenza and SARS-CoV-2 in particular.

“React and inject”: synthetic peptide-modified nanodiamonds as emergency pan-coronavirus vaccines

A recent study published in the MDPI journal, Pathogens, describes a coronavirus peptide vaccine antigen in the form of nanodiamond-based formulations, that demonstrated a robust and long-lasting immune response. The nanodiamonds proved to be a powerful and versatile platform for antigen conjugation. This could make it a safe and effective strategy for the production of off-the-shelf vaccines against multiple coronaviruses.

Mustard seed, wall rocket and turmeric extracts show potential against SARS-CoV-2 in vitro

Researchers in Spain have identified plant extracts that may be of interest in the search for treatments of coronavirus disease 2019 (COVID-19) and serve as a basis for future chemical, in vivo, and clinical trials.

Cationic peptides inhibit SARS-CoV-2 cell entry

In a paper recently published in Pathogens, in silico affinity studies by researchers at the University of Illinois, USA, reveal several potential peptide binding sites required for HS-spike protein and ACE2-spike protein bond formation, and synthesis of suitable peptide inhibitors reveals impaired SARS-CoV-2 cell entry.

Could the activation of FcγRIII/CD16 by anti-spike SARS-CoV-2 antibodies independently determine COVID-19 severity?

A team of scientists from Germany recently investigated whether hyperactivation of immune receptors that recognize the Fc part of an IgG molecule (FcγR) can lead to immunopathologic changes in coronavirus disease 2019 (COVID-19) patients. They have observed that hyperactivation of FcγRIII (CD16) by proinflammatory IgG antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can significantly contribute to COVID-19 related immunopathology.

Green tea catechins might be useful as pan-coronavirus inhibitors

Scientists from the Queen’s University, Canada, have recently uncovered the broad-spectrum antiviral activity of epigallocatechin gallate, a bioactive compound from green tea, against highly pathogenic coronaviruses found in humans and animals. The compound prevents viral infection by interfering with virus-host cell attachment. The study is currently available on the bioRxiv* preprint server.
