N-Heterocycles Scaffolds as Quorum Sensing Inhibitors. Design, Synthesis, Biological and Docking Studies
Quorum sensing is a communication system among bacteria to sense the proper time to express their virulence factors. Quorum sensing inhibition is a therapeutic strategy to block bacterial mechanisms of virulence. The aim of this study was to synthesize and evaluate new bioisosteres of N-acyl homoserine lactones as Quorum sensing inhibitors in Chromobacterium violaceum CV026 by quantifying the specific production of violacein. Five series of compounds with different heterocyclic scaffolds were synthesized in good yields: thiazoles, 16a-c, thiazolines 17a-c, benzimidazoles 18a-c, pyridines 19a-c and imidazolines 32a-c. All 15 compounds showed activity as Quorum sensing inhibitors except 16a. Compounds 16b, 17a-c, 18a, 18c, 19c and 32b exhibited activity at concentrations of 10 mu M and 100 mu M, highlighting the activity of benzimidazole 18a (IC50 = 36.67 mu M) and 32b (IC50 = 85.03 mu M). Pyridine 19c displayed the best quorum sensing inhibition activity (IC50 = 9.66 mu M). Molecular docking simulations were conducted for all test compounds on the Chromobacterium violaceum CviR protein to gain insight into the process of quorum sensing inhibition. The in-silico data reveal that all 15 the compounds have higher affinity for the protein than the native AHL ligand (1). A strong correlation was found between the theoretical and experimental results.
