RhlR modulators including agonist and antagonists which are useful for modulating QS phenotypes in Gram-negative bacteria. Certain compounds of general formula A-W-HG having various carbocyclic ad heterocyclic head groups (HG) and various tail groups (A), where W is CONH, SO.sub.2NH, CONHCH.sub.2, or SO.sub.2NHCH.sub.2 are RhlR agonists or antagonists. The compounds are useful in methods of modulating quorum sensing in Gram-negative bacteria, particularly in Pseudomonas. Compositions including certain RhlR modulators are useful for decreasing the virulence of Gram-negative bacteria. Pharmaceutical compositions comprising certain RhlR modulators are useful for treatment of infections of Gram-negative bacteria.
