Diastereoselective, Diversifiable Synthesis and Biological Evaluation of the Virginiamycin Inducers, the Virginiae Butanolides. [PDF]

open access: yesChembiochem
Production of natural products is tightly regulated, resulting in many silent biosynthetic gene clusters. BarA is a repressor that downregulates production of the virginiamycin antibiotics. The VBs are ligands for BarA that reverse its repression of virginiamycin production.

Thiotemplated Polyketide Chain Fusion and Reductive Cyclization Build the Reactive Butenolide Core of Malleicyprol. [PDF]

open access: yesAngew Chem Int Ed Engl
Malleicyprol, a virulence factor of notorious animal and human pathogens of the Burkholderia pseudomallei (BP) group, results from the fusion of two individual polyketide chains. The noncanonical condensation domain of the PKS–NRPS hybrid synthetase BurF forms an ester bond, and the terminal reductase domain mediates a reductive chain release followed ...

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.

Natural Products Inhibit Bacterial Growth and Modulate Quorum‐Sensing Systems Las and Rhl in Pseudomonas aeruginosa PA14

open access: yesChemistry &Biodiversity, Volume 22, Issue 12, December 2025.
ABSTRACT Quorum sensing (QS) is a bacterial cell communication system in Pseudomonas aeruginosa, which regulates the production of several virulence factors, including pyocyanin, exoproteases, and biofilm formation. Natural products (NPs) have demonstrated their ability to control QS in different bacteria. This work evaluated the antimicrobial and anti‐

β‐Amino Acid Synthesis Using the CO2 Radical Anion under Electrochemical and Photochemical Conditions

open access: yesChemistryEurope, Volume 3, Issue 6, November 11, 2025.
The development of sustainable methods for synthesizing β‐ and γ‐amino acids is crucial due to their significance in pharmaceuticals and materials science. This study introduces a novel strategy employing the CO2 radical anion as a key intermediate to access these amino acids from N‐Ac‐enamides and N‐Ac‐allylamines.

Unlocking Lactonase Enzymes as Biocatalysts for the Deracemisation of Chiral γ‐Thiolactones

open access: yesAngewandte Chemie, Volume 137, Issue 29, July 14, 2025.
The application of lactonase enzymes as biocatalysts still remains underexplored. This study discloses the biocatalytic activity of two lactonases in the deracemisation of chiral C3‐substituted‐γ‐thiolactones. The biocatalyst GcL catalyses the enzymatic kinetic resolution (EKR) of C3‐amide‐thiolactones, while the rationally engineered biocatalyst N9 ...

Understanding zwitterionic ring‐expansion polymerization through mass spectrometry

open access: yesMass Spectrometry Reviews, Volume 44, Issue 6, Page 918-946, November/December 2025.
Abstract Zwitterionic ring‐expansion polymerization (ZREP) is a polymerization method in which a cyclic monomer is converted into a cyclic polymer through a zwitterionic intermediate. In this review, we explored the ZREP of various cyclic polymers and how mass spectrometry assists in identifying the product architectures and understanding their ...
