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 -CO-NH-, -SO2-NH-, -CO-NH-CH2-, or -SO2-NH-CH2- 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.
RhlR调节剂包括激动剂和拮抗剂,对调节革兰氏阴性细菌中的QS表型有用。具有一般公式A-W-HG的某些化合物具有各种碳环和杂环头基团(HG)和各种尾基团(A),其中-W-为-CO-NH-,-SO2-NH-,-CO-NH-CH2-或-SO2-NH-CH2-是RhlR激动剂或拮抗剂。这些化合物在调节革兰氏阴性细菌中的群体感应方法中有用,特别是在铜绿假单胞菌中。包含某些RhlR调节剂的组合物有助于降低革兰氏阴性细菌的毒力。包含某些RhlR调节剂的药物组合物有助于治疗革兰氏阴性细菌感染。
