Comparing Chemoenzymatic and Conventional Synthetic Strategies to Wall Teichoic Acid Peptidoglycan Fragments

open access: yesIsrael Journal of Chemistry, Volume 66, Issue 5, September 2026.
The Gram‐positive bacteria, Staphylococcus aureus, contain wall teichoic acid (WTA, a glycopolymer (green and yellow)) is a virulence factor in their cell wall. Synthesis of the peptidoglycan‐(PG)‐WTA conjugate (blue squares) was developed via the phospho‐donor and PG acceptor (structures at the bottom right).

Assessing Vancomycin‐Formyl Peptide Conjugate Binding to the Surface of Resistant Staphylococcus aureus via Flow Cytometry

open access: yesChemBioChem, Volume 27, Issue 15, 14 August 2026.
A flow cytometry technique was developed to measure the binding of vancomycin‐formyl peptide conjugates to the surface of resistant Staphylococcus aureus. Binding results indicate that the labelling site of the vancomycin targeting element has a major effect on binding to the bacterial cell wall, which correlates with reduced antibiotic activity ...

Actinomycin Derivatives: Structural Diversification and Biological Activities

open access: yesChemMedChem, Volume 21, Issue 15, 14 August 2026.
Actinomycins are chromopeptide antibiotics exhibiting remarkable structural diversity and broad bioactivity. This review traces their development from naturally occurring D‐, X‐, A‐, G‐, Y‐, and Z‐type analogs to precursor‐directed, synthetic, and semisynthetic derivatives.

Fragmentation of Vancoresmycin Reveals a Strong Dependence on Global Molecular Architecture for Antibacterial Activity

open access: yesChemMedChem, Volume 21, Issue 15, 14 August 2026.
Fragmentation of the natural product vancoresmycin reveals an essential role of global architecture for biological potency. Vancoresmycin is a structurally complex tetramic‐acid‐containing natural product with potent activity against Gram‐positive bacteria, yet its structure–activity relationships remain poorly defined.
