Fluorescence Imaging of Azobenzene Photoswitching In Vivo

Abstract: Zebrafisch mit Schalter: Mithilfe eines fluoreszierenden Reporterpeptids gelingt es, die Photoisomerisierung von Azobenzol in vivo abzubilden (siehe Bild). Daraus folgt, dass photochemische Schalter auf Azobenzolbasis allgemein für die räumlich‐zeitliche Kontrolle in lebenden Systemen eingesetzt werden können.

“…In addition, photoswitchable cross-linkers could be developed that could be hooked up to two cysteine residues. [108] These have been used with great success to control the helical content of peptides, [108b, 109] and they have already found applications in governing the activity of proteins. [110] It is entirely possible that this approach could be extended to transmembrane receptors, thereby providing yet another way to control neural activity with light.…”

“…Daher stabilisieren elektronenziehende Reste Azobenzol gegenüber einer Reduktion durch GSH. [232] Gerade bei der Kontrolle der Sekundärstruktur und Funktion von Peptiden und Proteinen spielt die photochemisch induzierte ¾nderung des End-zu-End-Abstands eine wichtige Rolle für die funktionellen Veränderungen im Zielmolekül. [230,231] Daher untersuchten Woolley und Mitarbeiter die Eignung von Azobenzol für intrazelluläre Photoregulation in lebenden Organismen, indem sie ein mit Azobenzol vernetztes fluoreszierendes Reporterpeptid in Zebrafischembryonen injizierten.…”

“…The feasibility of using azobenzene systems in living organisms to photocontrol biological events has been confirmed by the in vivo imaging of the isomerization process in zebrafish. [9] An intrinsic hindrance for applications of azobenzene in living cells derives from its susceptibility to reduction. The azo unit may be subject to reduction by enzymes [10] or thiols such as glutathione (GSH) which is present in most cells at millimolar concentration (0.5-10 mm).…”
