Fragment‐Based Design of Targeted Covalent Inhibitors: The Scope and Limitation of Linking Approaches

open access: yesChemMedChem, Volume 21, Issue 10, 27 May 2026.
This paper by Kollár et al. reports a covalent fragment linking study against the SARS‐CoV‐2 main protease (3CLPro). Beginning with inactive fragment hits, the application of rational linker design enabled the generation of reversible covalent inhibitors exhibiting low micromolar potency. The study details some general limitations and best practices of

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

open access: yesChemMedChem, 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 ...

Severe Occupational Hypersensitivity Pneumonitis: A Case Series of Four Patients Requiring Lung Transplantation

open access: yesAmerican Journal of Industrial Medicine, Volume 69, Issue 5, Page 323-334, May 2026.
ABSTRACT Hypersensitivity pneumonitis (HP) is an immune‐mediated interstitial lung disease triggered by repeated inhalation of organic or chemical antigens. Occupational exposures account for approximately 19% of all cases. Early diagnosis, identification of the responsible antigen(s), and immediate avoidance of exposure are crucial to prevent ...

Impact of Early COVID‐19 Antiviral Therapy on the Incidence of Uveitis: A Retrospective Cohort Study Using the TriNetX Database

open access: yesImmunity, Inflammation and Disease, Volume 14, Issue 5, May 2026.
ABSTRACT Objective To assess whether antivirals are associated with a reduced incidence of uveitis following COVID‐19. Methods We conducted a multi‐institutional, population‐based retrospective cohort study of adults (≥ 18 years) diagnosed with COVID‐19 between 2022 and 2024. Patients who received antiviral agents (Paxlovid, Molnupiravir, or Remdesivir)

Carbohydrate‐Based Drug Discovery: Synthetic Strategies and Clinical Applications

open access: yesIsrael Journal of Chemistry, Volume 66, Issue 3, May 2026.
The picture depicts the molecules discussed in the review. On the left side, the general scaffold of sugars is shown. Next to it are four carbohydrate‐based molecules, including remdesivir, islatravir, empagliflozin, and Globo‐H. Remdesivir and islatravir contain a substituted ribose ring attached to a modified nucleobase.

Extending the Targets for Coronavirus Antivirals Beyond That of Approved Drugs: Insights From Preclinical Research

open access: yesMicrobial Biotechnology, Volume 19, Issue 5, May 2026.
Chemical structure of RIBOTAC inhibitor with metabolic handle binding as nucleotide analogue to SARS‐CoV‐2 RNA dependent RNA polymerase, its linker and the RNase L recruiter which binds RNase L monomers and mediates their dimerization that actives nuclease activity degrading the viral RNA.
