Toward Dual-Target Glycomimetics against Two Bacterial Lectins to Fight Pseudomonas aeruginosa - Burkholderia cenocepacia Infections: A Biophysical Study. J.Med.Chem., 68:9681-9693, 2025 Cited by PubMed Abstract: Chronic lung infections caused by and pose a severe threat to immunocompromised patients, particularly those with cystic fibrosis. These pathogens often infect the respiratory tract, and available treatments are limited due to antibiotic resistance. Targeting bacterial lectins involved in biofilm formation and host-pathogen interactions represents a promising therapeutic strategy. In this study, we evaluate the potential of synthetic fucosylamides as inhibitors of the two lectins LecB () and BC2L-C-Nt (). Using a suite of biophysical assays, we assessed their binding affinities, identifying three β-fucosylamides as promising dual-target ligands, while crystallography studies revealed the atomic basis of these ligands to interact with both bacterial lectins. The emerged classes of compounds represent a solid starting point for the necessary hit-to-lead optimization for future dual inhibitors aiming at the treatment of coinfections with these two bacterial pathogens.
