Pseudomonas aeruginosa employs a quorum sensing (QS) communication system that makes use of small diffusible molecules. Among other effects, the QS system coordinates the formation of biofilm which decisively contributes to difficulties in the therapy of
Novel small molecule inhibitors targeting the "switch region" of bacterial RNAP: Structure-based optimization of a virtual screening hit

Rising resistance against current antibiotics necessitates the development of antibacterial agents with alternative targets. The "switch region" of RNA polymerase (RNAP), addressed by the myxopyronins, could be such a novel target site. Based on a hit can
Combining in silico and biophysical methods for the development of pseudomonas aeruginosa quorum sensing inhibitors: An alternative approach for structure-based drug design

The present work deals with the optimization of an inhibitor of PqsD, an enzyme essential for Pseudomonas aeruginosa quorum sensing apparatus. Molecular docking studies, supported by biophysical methods (surface plasmon resonance, isothermal titration cal

This paper describes a general procedure for the synthesis of new substituted thiaisatoic anhydrides or 6- or 7-aryl-1H-thiéno[3,2-d][1,3] oxazine-2,4-diones 3a-j and 4a-f. They were synthesized in large scale under microwave heating conditions with high yields. The reactivity vs nucleophilic reagents of these compounds was studied and permitted to develop a simple combinatorial procedure to synthesize a library of new thiophene ureidoacids 7a-j and 8a-j.
