Biochem/physiol Actions

Wirkungsweise: Chloramphenicol hemmt die bakterielle Proteinsynthese durch Blockierung des Peptidyltransferaseschrittes, indem es an die ribosomale 50S-Untereinheit bindet und die Bindung der Aminoacyl-tRNA an das Ribosom verhindert. Es hemmt auch die mitochondriale und chloroplastische Proteinsynthese und die ribosomale Bildung von (p)ppGpp, wodurch die rRNA-Transkription unterdrückt wird.

Resistenzmechanismus: Die Verwendung von Chloramphenicol-Acetyltransferase führt zur Acetylierung und Inaktivierung des Produkts.

Antimikrobielles Spektrum: Es handelt sich um ein Breitbandantibiotikum gegen grampositive und gramnegative Bakterien, das vor allem in der Augenheilkunde und in der Tiermedizin eingesetzt wird.
