Quorum sensing is a regulatory system used by bacteria for controlling gene expression in response to increasing cell density. Controlling bacterial infections by quenching their quorum sensing systems is a promising field of study. The expression of specific target genes, such as transcriptional regulators...

N-hexanoyl-DL-Homoserine lactone is a bacterial quorum sensing signaling molecule that is produced by mammalian pathogenic and rhizosphere-colonizing bacteria. Application of N-hexanoyl-DL-homoserine lactone (60 µM) to tomato leaves suppresses the development of lesions induced by the plant pathogenic fungi B....

Type 4 cyclic nucleotide phosphodiesterases (PDE4) isoforms selectively inactivate the second messenger cAMP by hydrolyzing the phosphodiester bond, producing AMP. (±)-Rolipram is a cell-permeable selective PDE4 inhibitor. Since PDE4 is abundant in leukocytes, (±)-rolipram inhibits inflammation by suppressing...
