Abstract

Quorum sensing, an important process of bacterial communication, is involved in the development of complex behavior and expression of virulence factors that become important due to its key role in infection process. In this manuscript, docking studies were used as a preliminary screening to identify main interactions between LuxR receptor (CviR) of Chromobacterium violaceum as model and N‐acyl L‐homoserine lactones. Thus, following this approach, a library of imidazo[1,2‐a]pyridines bearing carboxamide and urea moieties was designed, evaluated on this in silico model previously validated, and synthesized to generate new potential quorum sensing inhibitors. The present article summarizes survey to develop these new molecules with potential biological activity, based on interaction analysis ligand‐receptor.
