The Burkholderia cepacia complex (BCC) is a group of Gram-negative bacteria known for their pathogenicity to patients suffering from cystic fibrosis (CF). BCC-belonging strain B. pyrrocinia BC11 (formerly BC11) produces AFC-BC11, compound with strong activity against phytopathogenic fungi. In this contribution, we report on the unprecedented N-acyl-tetrapeptide structure and antifungal potency natural product. We further provide insights into central steps its biosynthesis mediated by nonclassical nonribosomal peptide synthesis machinery lacking condensation domains. With involvement sole acyl/peptidyl carrier protein AfcK, an acyltransferase AfcL coenzyme A, growing acyl-peptide chain shuffled between different thioester carriers during intricate biosynthetic assembly. knowledge AFC-BC11 may contribute development antifungals phytopathogens and, afc gene cluster being conserved in various strains, possibly understanding human pathogenesis BCC.

Plant bacterial diseases have precipitated a global crisis in human health and food security. In agriculture, such as the rice white-leaf blight can cause considerable reduction crop yields and, extreme cases, complete failure. Therefore, there is an urgent need for novel green pesticides with innovative modes-of-action (MoAs). A series of zingerone derivatives isopropanolamine skeleton were designed their quorum-sensing effects estimated using biomimetic strategies. The results showed that compound A12 effectively inhibits growth Xanthomonas oryzae pv. [Xoo, median effective concentration (EC50) = 3.55 μg mL-1], axonopodis citri (Xac, EC50 3.23 mL-1) oryzicola (Xoc, 7.48 mL-1). Molecular docking revealed forms multiple interactions RpfF protein, while fluorescence titration experiments further verified interaction between them. Additionally, was found to inhibit Xoo biofilm formation, extracellular polysaccharide production other virulence factors. vivo pot exhibited excellent curative (53.59%) protective (57.65%) activity against Xoo. conclusion, A12's primary MoA achieved by affecting formation biofilms expression various factors, including related genes. summary, this study highlights displays notable sensing activity. advancement inhibitors through strategies offers promising avenues future research. © 2025 Society Chemical Industry.

Abstract In the era of precision medicine, photopharmacology that employs molecular photoswitches offers unique opportunities to control action bioactive molecules with high spatiotemporal resolution, while reducing drug side effects, systemic toxicity and emergence resistance. Over past two decades, field has witnessed great achievements in treating blindness, cancer, diabetes, antibiotic resistance, name but a few. Several challenges remain, however, particular fact most photopharmacological agents trigger their activity by Ultraviolet light, which is damaging normal cells poor tissue permeability. Visible light‐activated are hence highly desirable have captured keen recent research interest. This review highlights strategies for synthesis visible light‐responsive azobenzenes (ABs) applications emerging photopharmacology. Such photoswitchable drugs tremendously extend scope future vivo applications. Furthermore, we identify current discuss rational design switches at higher wavelength. We hope inspire further into photochemistry novel based on ABs or other photoswitches, triggered excitation light “phototherapeutic window” 650–900 nm, ultimately enabling full realization these “smart” clinical practice.
