Synthesis and Evaluation of Water-Soluble 2-Aryl-1-Sulfonylpyrrolidine Derivatives as Bacterial Biofilm Formation Inhibitors.

The approach to the novel 1-[(2-aminoethyl)sulfonyl]-2-arylpyrrolidines via unique intramolecular cyclization/aza-Michael reactions of N-(4,4-diethoxybutyl)ethenesulfonamide have been developed, which benefits from high yields of target compounds, mild reaction conditions, usage of inexpensive and low-toxic reagents, and allows for wide variability in both amine and aryl moieties. Biotesting with whole-cell luminescent bacterial biosensors responding to DNA damage showed that all tested compounds are not genotoxic. Tested compounds differently affect the formation of biofilms by Vibrio aquamarinus DSM 26054.
