متن کاملOrganocatalytic enantio- and diastereoselective synthesis of highly substituted δ-lactones via a Michael-cyclization cascade.
An organocatalyzed Michael-cyclization cascade approach of readily available α,β-unsaturated aldehydes and pyrazoleamides has been developed to get highly substituted δ-lactones in excellent enantioselectivities (up to 97%) and diastereoselectivities. The δ-lactones so obtained could easily be transformed into benzazepine derivatives with excellent enantio- and diastereoselectivities. Furthermo...
متن کاملCharacteristics of N-Acylhomoserine Lactones Produced by Hafnia alvei H4 Isolated from Spoiled Instant Sea Cucumber
This study aimed to identify N-acylhomoserine lactone (AHL) produced by Hafnia alvei H4, which was isolated from spoiled instant sea cucumber, and to investigate the effect of AHLs on biofilm formation. Two biosensor strains, Chromobacterium violaceum CV026 and Agrobacterium tumefaciens KYC55, were used to detect the quorum sensing (QS) activity of H. alvei H4 and to confirm the existence of AH...
متن کاملN-Acylhomoserine Lactones (AHLs) as Phenotype Control Factors Produced by Gram-Negative Bacteria in Natural Ecosystems
Bacteria are able to sense an increase in cell population density and to respond to it by the induction of a particular set of genes. This mechanism, called quorum sensing, includes in gram-negative bacteria the production and secretion of an acyl homoserine lactone, which diffuses through the cell wall, from the cell to the medium. Bacteria use the quorum sensing mechanism to regulate a variet...
متن کاملCharacterization of N-Acylhomoserine Lactones Produced by Bacteria Isolated from Industrial Cooling Water Systems
The cooling water systems are used to remove heat generated in the various industries. Biofouling of the cooling water systems causes blocking of condenser pipes and the heat exchanger tubes. In many Gram-negative bacteria, N-acylhomoserine lactone (AHL) are used as quorum-sensing signal molecule and associated with biofilm formation. To investigate the relationship between quorum sensing and b...
