Catch, Cut, or Block? Versatile 4‐N‐Derivatized Sialyl Glycosides for Influenza Virus Neuraminidase Detection and Purification

Angewandte Chemie, EarlyView.
Sialyl glycosides containing 4‐N‐derivatized sialic acids synthesized by a highly efficient one‐pot two‐enzyme (OP2E) chemoenzymatic sialylation strategy have been shown to be versatile probes. They can resist sialidase cleavage, be selective substrates by influenza sialidases, or be nanomolar substrate analog‐based inhibitors and affinity ligands ...

Systematic Comparison of Commercial Uranyl‐Alternative Stains for Negative‐ and Positive‐Staining Transmission Electron Microscopy of Organic Specimens

Advanced Healthcare Materials, EarlyView.
Negative‐ and positive‐staining TEM is essential for rapid nanometer‐resolution characterization of organic specimens ranging from nanoparticles to cells. Uranyl salts are widely used negative‐/positive‐stains but are radioactive and highly toxic to users and the environment.

Nuclear‐Localized BCKDK Facilitates Homologous Recombination Repair to Support Breast Cancer Progression and Therapy Resistance

Advanced Science, EarlyView.
Under DNA damage, tumor cells rely on efficient DNA repair for survival and therapy resistance. This study has demonstrated that BCKDK localizes to breast cancer cell nuclei, where it binds to and phosphorylates RNF8, thereby blocking ubiquitin‐mediated degradation of RAD51 and enhancing HRR. A selective BCKDK inhibitor synergizes with clinical agents,

A Reversible and Dynamic Surface Functionalization for Fluidity Controlled Multivalent Recognition of Lectins and Bacteria

Advanced Science, EarlyView.
A reversible wet chemical surface functionalization results in dynamic multivalent receptors showing ligand‐specific high affinity for lectins and bacteria. Abstract The paper reports the design of multivalent bacterial receptors based on reversible self‐assembled monolayers (rSAMs) on gold and glass substrates, mimicking the ligand display on host ...

Gasdermin D‐Mediated Pyroptosis Exerts Two Opposite Effects of Resisting Enzymatic Digestion and Expanding Inflammatory Response in Acute Pancreatitis

Advanced Science, EarlyView.
Gasdermin D (GSDMD) does not only reduce pancreatic enzyme synthesis but also induces pancreatic acinar cells to express mucin 1 (MUC1), which forms a barrier to prevent digestive enzyme‐mediated digestion. However, GSDMD can promote the secretion of inflammatory cytokines by macrophages and aggravate pancreatic histological injury by expanding ...

Trypstatin as a Novel TMPRSS2 Inhibitor with Broad‐Spectrum Efficacy against Corona and Influenza Viruses

Advanced Science, EarlyView.
Trypstatin, a 61‐amino acid Kunitz‐type protease inhibitor derived from human Bikunin, potently inhibits TMPRSS2 and related proteases. It blocks spike‐ and hemagglutinin‐mediated entry of multiple respiratory viruses in vitro reduces SARS‐CoV‐2 replication in human airway cultures, and lowers viral load and symptoms in infected hamsters, demonstrating

Antiviral effects and mechanism of Qi pi pill against influenza viruses

Animal Models and Experimental Medicine, EarlyView.
Qi pi pill presents anti‐influenza effect and inhibits viral replication in vitro by targeting both the viral RNA replication and the release of new viral particles. Furthermore, QPP modulates the production of proinflammatory cytokines induced by influenza infection in host cells.

The Antiviral Activity of Polyphenols

Molecular Nutrition &Food Research, EarlyView.
Polyphenols demonstrate remarkable antiviral properties by effectively disrupting multiple biochemical processes essential for viral replication. ABSTRACT Polyphenols are secondary metabolites produced by a large variety of plants. These compounds that comprise the class of phenolic acids, stilbenes, lignans, coumarins, flavonoids, and tannins have a ...
