P. aeruginosa, such as PYO production and swarming motility, may beconsidered the starting point to the development of chemical probesthat shed light on P. aeruginosa virulence mechanisms. Several studieshave shown that flavonoids inhibit bacterial QS mechanisms and, as aconsequence, inhibit the expression of virulence traits. Our results pointout that calycopterin presents a different mechanism of action, that iscompatible with c-di-GMP levels modulation. However, this hypothesisrequires further investigation by other methods, such as direct or indirect measurement of c-di-GMP and expression levels of genes relatedto quorum sensing and pyocyanin biosynthesis in P. aeruginosa grown inpresence of calycopterin as compared to control conditions. The uniquebiological signature of calycopterin points to its utility in another essential aspect of drug development: the thorough investigation of P.aeruginosa transition from planktonic to sessile lifestyles
