Abstract
A diversity-oriented collection of furan-2-carboxamides with antibiofilm activity against P. aeruginosa is reported. The design involved the bioisosteric replacement of the labile furanone ring by a furan-2-carboxamide moiety to explore its influence on biological activity. After evaluation, carbohydrazides and triazoles showed significant antibiofilm activity, and 4b resulted in the most remarkable compound (58 % inhibition). Furthermore, treating P. aeruginosa with three active carboxamides reduced some virulence factors (pyocyanin and proteases), confirming the anti-quorum sensing properties of the derivatives and suggesting LasR as a plausible target. Molecular docking proposed that carbohydrazides share a similar binding mode to related furanones inside LasR with an excellent docking score, while higher derivatives diminished in silico affinity.
期刊介绍：
Quality research. Outstanding publications. With an impact factor of 3.124 (2019), ChemMedChem is a top journal for research at the interface of chemistry, biology and medicine. It is published on behalf of Chemistry Europe, an association of 16 European chemical societies.
ChemMedChem publishes primary as well as critical secondary and tertiary information from authors across and for the world. Its mission is to integrate the wide and flourishing field of medicinal and pharmaceutical sciences, ranging from drug design and discovery to drug development and delivery, from molecular modeling to combinatorial chemistry, from target validation to lead generation and ADMET studies. ChemMedChem typically covers topics on small molecules, therapeutic macromolecules, peptides, peptidomimetics, and aptamers, protein-drug conjugates, nucleic acid therapies, and beginning 2017, nanomedicine, particularly 1) targeted nanodelivery, 2) theranostic nanoparticles, and 3) nanodrugs.
