Mechanisms compared
Amoxil: Amoxicillin hemmt die bakterielle Zellwandsynthese durch Bindung an Penicillin-bindende Proteine (PBP) und blockiert die Quervernetzung der Peptidoglykan-Stränge. Doxycycline: Doxycyclin bindet reversibel an die 30S-Untereinheit der bakteriellen Ribosomen empfindlicher Erreger und hemmt die Proteinsynthese, indem es die Bindung der Aminoacyl-tRNA an die ribosomale A-Stelle verhindert.
