Abstract
We report the synthesis of the sensitive and specific fluorogenic self-immolative substrate 8b, which is hydrolzyed by β-alanyl aminopeptidase (BAP), resulting in a 1,6-elimination and the release of the highly fluorescent hydroxycoumarin 6b. This fluorophore 6b is retained within bacterial colonies, so has potential for the detection of P. aeruginosa (a BAP producer); it also has potential in liquid media due to the rapid and strong signal release from the substrate 8b, and lack of self-quenching or photobleaching.We report the synthesis of the sensitive and specific fluorogenic self-immolative substrate 8b, which is hydrolzyed by β-alanyl aminopeptidase (BAP), resulting in a 1,6-elimination and the release of the highly fluorescent hydroxycoumarin 6b.
