resistance they acquire. One of the defense mechanisms of resistant bacteria is the formation of biofilms. Herein we show that benzimidazoliumsalts with various flexible or rigid side chains act as strong antibiotic and antibiofilm agents. We show that their antibiofilmactivity is due to their capacity to destroy the biofilm matrix and the bacterial cellular membranes. These compounds are able to avoid

Herein, we present the first example of a benzimidazolium-based artificial transmembrane chloride transporter and a synthetic calcium ionophore that can regulate intracellular calcium concentrations in bacteria.

exhibited robust antimicrobial activity while maintaining a high level of selectivity compared with mammalian cells. Our investigations revealed significant antibiofilmactivity, as these compounds rapidly acted against established biofilms. In addition, bis-benzimidazolium compounds exhibited consistent results in resistance development and cross-resistance studies. Consequently, amphiphilic bis-benzimidazolium
