A Sequence‐Based Update on Amino Acid Substitutions in Influenza Polymerase Acidic Protein in Europe That Alter Baloxavir Susceptibility From 2009 to 2025

open access: yesInfluenza and Other Respiratory Viruses, Volume 20, Issue 7, July 2026.
ABSTRACT Background Influenza causes 650,000 deaths, 3–5 million hospitalizations, and 1 billion cases worldwide each year. There is a limited repertoire of antivirals available to tackle this burden, highlighting the risk of developing resistance to current drugs.

Structural Elucidation and Engineering of the (S)‐scoulerine 2‐O‐Methyltransferase Enabling Regioselective Epiberberine Biosynthesis in Coptis chinensis

open access: yesPlant Biotechnology Journal, Volume 24, Issue 7, Page 4528-4545, July 2026.
ABSTRACT Protoberberine alkaloids are a characteristic group of natural products in Coptis plants known for their notable pharmacological activities. However, the structural similarity and the substrate promiscuity of their biosynthetic enzymes have left the precise synthetic pathways remain unclarified, posing challenges to regulate product formation.

Crystal Structure and Conformational Dynamics of N─N Bond‐Forming Piperazate Synthase

open access: yesChemBioChem, Volume 27, Issue 12, 26 June 2026.
Piperazate synthases (PZSs) catalyze the key N─N bond formation in the biosynthesis of the rare amino acid piperazic acid. X‐ray crystal structures of apo‐ and holo‐SbPZS show a dimeric enzyme with two heme‐containing active sites, where histidine residues coordinate the iron centers.

Synthesis and Evaluation of Aromatic Sulfonamide and Disulfonamide Derivatives as Dengue Virus NS3–NS5 Interaction Inhibitors

open access: yesChemMedChem, Volume 21, Issue 11, 15 June 2026.
A synthetic methodology for the preparation of asymmetric benzene‐1,4‐disulfonamides was developed and applied to generate potential anti‐dengue virus (DENV) compounds. Guided by computer‐assisted structural rationalization, we designed synthetically more accessible analogs with reduced toxicity that interact with the DENV NS5 domain, thereby ...
