Experience from an HTS campaign: Investigation of susceptibility and rescue of SARS-CoV-2 nsp3 protease assay from metal contamination

SLAS Technology
Different biochemical assays yield different rates of false positives than others either due to the nature of the enzyme, the technology associated with the bioassay, or properties of the compounds being screened.

Advancing Antiviral Design: Integrating Natural Products, Computation and Targeted Delivery

Chemical Biology &Drug Design, Volume 108, Issue 1, July 2026.
A stepwise translational framework linking natural‐product discovery, computational prioritisation, experimental validation, lead optimisation and targeted delivery is proposed to advance antiviral design. ABSTRACT The COVID‐19 pandemic highlighted the role of rapid viral mutation and global connectivity in accelerating viral emergence and spread ...

High-resolution functional mapping of the venezuelan equine encephalitis virus genome by insertional mutagenesis and massively parallel sequencing. [PDF]

PLoS Pathogens, 2010
We have developed a high-resolution genomic mapping technique that combines transposon-mediated insertional mutagenesis with either capillary electrophoresis or massively parallel sequencing to identify functionally important regions of the Venezuelan ...

SARS‐CoV‐2 enhances lysosomal exocytosis and deacidifies lysosomes to facilitate viral release

mLife, Volume 5, Issue 3, Page 339-354, June 2026.
Abstract The mechanism of SARS‐CoV‐2 egress predominantly governs the quantity and quality of progeny viruses, thereby significantly contributing to viral pathogenicity. However, the key factors influencing viral egress remain largely unclear. In this study, using transcription‐ and replication‐competent SARS‐CoV‐2 virus‐like‐particle (SARS‐CoV‐2 trVLP)

Structural analysis of the flexibility of the Ubl2 domain within the papain‐like protease of SARS‐CoV‐2

Acta Crystallographica Section F, Volume 82, Issue 6, Page 222-230, June 2026.
The ubiquitin‐like domain 2 (Ubl2) of the SARS‐CoV‐2 virus is necessary for the stability and catalytic efficiency of its papain‐like protease (PLpro). Our crystallographic study reveals that the Ubl2 domain exhibits notable flexibility and can adopt a conformation that places itself away from the PLpro catalytic domain, representing a new conformation

Key residues in SARS-CoV-2 NSP3 hypervariable region are necessary to modulate early stress granule activity

Journal of Virology
Antagonism of the host responses that limits viral replication is critical to the success of infection. Recently, we identified that the hypervariable region (HVR) of SARS-CoV-2 NSP3 binds to FXR1 and disrupts stress granule formation during the early ...

Inhibitors Targeting SARS‐CoV‐2 Papain‐Like Protease: Screening, Design, Synthesis, and Biological Evaluation

ChemMedChem, Volume 21, Issue 9, 14 May 2026.
In our study, we obtained both non‐covalent and covalent PLpro inhibitors. Additionally, the stable protein‐ligand interactions of the active compound were examined using advanced computational docking and molecular dynamics simulations. The non‐covalent inhibitor 2t showed antiviral activity with an EC50 of 2.89 µM, indicating its potential as a ...

Adapted Live SARS‐CoV‐2 Vaccine Elicits Rapid Mucosal Immunity, Protects From Disease, and Reduces Shedding of XBB.1.5

European Journal of Immunology, Volume 56, Issue 5, May 2026.
An attenuated live vaccine (OTS‐300) expressing the XBB.1.5 Spike provided rapid and complete protection against homologous challenge in the hamster model, accompanied by fast systemic and mucosal antibody responses and markedly reduced transmission compared with XBB.1.5 mRNA vaccination.

Viral Mechanisms and Drug Influences on Janus Kinase/Signal Transducers and Activators of Transcription (JAK/STAT) Pathway in Human Coronaviruses Infection: A Systematic Review

Health Science Reports, Volume 9, Issue 5, May 2026.
ABSTRACT Background and Aim Janus kinases/signal transducers and activators of transcription (JAK/STAT) pathway is crucial for various stages of immunity, from innate to adaptive responses. Type 1 IFNs activate JAK/STAT pathway by binding to receptors on JAK, phosphorylating STAT and upregulating interferon‐stimulated genes (ISGs) leading to cytokines ...
