    Abstract: 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-, -SO 2 -NH-, -CO-NH-CH 2 -, or -SO 2 -NH-CH 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.

    Abstract: The invention concerns a method of nitrosation of a phenolic compound substituted by an electro-attracting group.The invention also concerns a method of nitration of a phenoic compound substituted by an electro-attracting group. The nitrosation method is characterised in that it consists in effecting the nitrosatio n of the said compound in presence of sulphuric acid; the concentration of the sulphuric acid being at least 60 % by weight, then optionally in effecting the separation of the resulting nitrosated compound. The invention also concerns the oxidation of the resulting p-nitrosated phenolic compound for obtaining the corresponding nitrated compound.
