rhamnolipid

Rhamnolipid RL2, a rhamnolipid, exhibits antifungal activity [1] [2].

Hexyl gallate (Gallic acid hexyl ester), an alkyl ester derivative of gallic acid, exhibits potent antimalarial activity against Plasmodium falciparum (IC50: 0.11 mM).

RhlR antagonist 1 is a highly effective antagonist of the RhlR protein, showing an IC50 value of 26 μM. It exhibits selective antagonistic activity against RhlR, with minimal effect on LasR and PqsR. RhlR antagonist 1 strongly inhibits biofilm formation in both static and dynamic environments and reduces the production of virulence factors, such as rhamnolipid and pyocyanin, in P. aeruginosa. These characteristics make RhlR antagonist 1 a valuable tool for the development of molecules that modulate quorum sensing and control P. aeruginosa infections [1].

N-Decanoyl cyclopentylamide (C10-CPA) serves as a potent quorum sensing inhibitor in Pseudomonas aeruginosa, disrupting the expression of virulence factors governed by both the las and rhl systems. It effectively suppresses the production of elastase, pyocyanin, rhamnolipid, and hinders biofilm formation.
