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....

Okadaic acid is a marine sponge toxin which potently inhibits certain serine/threonine protein phosphatases. This cell permeable inhibitor targets the multiple isoforms of PP1 (IC50 = 10-50 nM), both isoforms of PP2A (IC50 = 0.5 nM) and PP3 (IC50 = 4 nM). It is a very weak inhibitor of PP2B (IC50 > 2 µM) and does...
