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.
Abstract:

Abstract:
The invention provides branched hydrophobes for the production of surfactants with improved properties over linear hydrophobes. The invention also provides branched C10-12 enals and aldehydes that are oxidized to branched fatty acids or hydrogenated to branched fatty alcohols and further derivatized to surfactants, through ethoxylation or esterification and other or subsequent reactions. The invention further provides surfactants made from the branched trialkylamine intermediates, including amphoteric, cationic and nonionic surfactants.
Abstract:
Process for the preparation of organic isocyanates in which a furoxan is heated in the presence of a vicinal diketo compound containing two adjacent keto carbonyl groups. When the furoxan ring is fused to an organic ring system di-isocyanates are produced. An adduct of the furoxan and the diketo compound may be isolated from the reaction mixture and used as a stable isocyanate precursor, for example, a "one-pot" polyurethane composition.
Abstract:
Process for carrying out nitrosation reactions and diazotization reactions by reacting the concerning compound with a nitrite in the presence of an acid wherein ammonium-nitrite is used as the nitrite.
Abstract:
Processes for the preparation of 8,14-cedranoxide are disclosed, according to which 8,14-cedrane diol is prepared by reducing 8,14-cedranolide by treatment with the aid of diisobutyl-aluminum hydride followed by acid hydrolysis, or 8,14-cedrane diol is cyclized with dimethyl sulfoxide.
