Announcements and Reports


Die Wirkungsbezogene Analytik stellt ein Konzept dar, welches nicht auf der analytisch-chemischen Detektion einzelner Substanzen, sondern auf dem Nachweis der Wirkungen dieser Substanzen auf biologische Systeme basiert. Somit ermöglicht die Wirkungsbezogene Analytik auch die Detektion unbekannter Schadsubstanzen. Detailliertes Wissen über die molekularen Grundlagen toxischer Wirkungen ist dabei notwendig, um geeignete wirkungsbasierte biologische Testsysteme zu entwickeln. Der bekannteste Vertreter solch eines Testsystems ist der CALUX-Test zur Bestimmung Dioxin-ähnlicher Wirkungen auf den Aryl-Hydrocarbon-Rezeptor mittels eines Luciferase-Reportersystems. Derartige Testsysteme erlauben die zuverlässige Detektion einzelner toxischer Wirkmechanismen. Im diesem Beitrag sollen mögliche methodische Weiterentwicklungen der Wirkungsbezogenen Analytik skizziert werden, mit deren Hilfe in Zukunft die parallele Detektion unterschiedlicher molekularer Mechanismen der Toxizität möglich sein könnte. Zudem wird ein Zukunftsbild der Wirkungsbezogenen Analytik in der Lebensmittelsicherheit skizziert.

The concept of effect-based analytics is based on the detection of substance-induced effects in biological test systems, not on the identification of individual compounds by classic analytic chemistry. Effect-based analytics thus also allows for the detection of unknown harmful substances. Detailed knowledge about the molecular basis of toxic effects is necessary for the development of appropriate effect-based biological tests. The best-known example for such a test system is the CALUX assay for the detection of dioxin-like effects at the aryl hydrocarbon receptor by the use of a luciferase reporter system. Such test systems allow for the reliable detection of individual modes of action in toxicology. In this paper, possible further developments in effect-based analytics will be discussed, by which parallel detection of different molecular mechanisms of toxicity might be possible in the future. Furthermore, a vision of future effect-based analytics in the area of food safety is drafted.
