Genetic tracing at the Huanan Seafood market further supports COVID animal origins

Science Daily: Pharmacology News

A new study provides a list of the wildlife species present at the market from which SARS-CoV-2, the virus responsible for the COVID-19 pandemic, most likely arose in late 2019. The study is based on a new analysis of metatranscriptomic data released by the Chinese Center for Disease Control and Prevention (CDC).

Design, Synthesis, X-ray Crystallography, and Biological Activities of Covalent, Non-Peptidic Inhibitors of SARS-CoV-2 Main Protease

Covalent Modifiers

3c00565 Highly contagious SARS-CoV-2 coronavirus has infected billions of people worldwide with flu-like symptoms since its emergence in 2019. Chloroacetamide inhibitor 13 and epoxide inhibitor 30 were found to inhibit cellular SARS-CoV-2 replication with an EC68 (half-log reduction of virus titer) of 3 and 5 μM.

Researchers engineer in vivo delivery system for prime editing, partially restoring vision in mice

Broad Institute

Williams January 8, 2024 Credit: Susanna Hamilton, Broad Communications Researchers have developed virus-like particles that can deliver gene-editing cargo to cells, including those in the mouse brain. Prime editing, described in 2019 by Liu’s group, can make longer and more diverse types of DNA changes than other types of editing.

RNA: The most attractive target in recent viral diseases

Chemical Biology and Drug Design

These strategies act by taking advantage of the weakness points of this attractive bioweapon to disable or attack it (itself), accordingly stop the entire viral reproduction, and effectively end the severe microbial infections such as the coronavirus disease 2019 (COVID-19). SARS-CoV-2) to infect humans and spread infections.

Can Global Genomic Surveillance Forecast the Next Pandemic?

PLOS: DNA Science

A Novel Virus Appears In retrospect, everything unfolded with astonishing speed. ” I’ve long thought that SARS-CoV-2, or an immediate viral predecessor, emerged years before 2019 – at least as far back as 2013. .” But I think about that time often, and the warning that it sounded. Work on vaccines ensued too.

Advancing vaccine design: potential of peptide mimicry

Drug Target Review

In a new development, a recent paper published in Biology Methods & Protocols by Oxford University Press has highlighted a promising avenue for enhancing vaccine efficacy against infectious pathogens like the COVID-19 virus. Since December 2019, SARS-CoV-2 (COVID-19) infection has become a worldwide urgent public health concern.

Day Zero Antivirals for Future Pandemics

Codon

When COVID-19 emerged in 2019, by contrast, mRNA vaccines developed by Pfizer and Moderna took just 326 days from the initial sequencing of the virus to gaining approval for emergency use. These drugs would be ideal tools to bridge the wait for a vaccine against a quickly-spreading virus.
