Evaluation of the impact of the efflux pump modulation process on the anti-adhesion and antibiofilm activities of analogues of natural marine compounds in a marine bacterium

November 2023

One strategy for enhancing the effect of natural marine antifouling compounds has been to combine them with coumarin-type molecules (VL2, VL17 and VL19). These molecules are known to have an inhibitory effect on the efflux pumps (EP) of a large number of Gram-negative bacteria. To this end, they have been used as adjuvants to natural marine compounds (OB1, AS194 and AS162) to enhance their antibiofilm activity. On the...
