Mechanism and action
Doxycycline: Doxycyclin bindet reversibel an die 30S-Untereinheit bakterieller Ribosomen, verhindert die Bindung von Aminoacyl-tRNA und hemmt damit die Proteinsynthese. Amoxil: Amoxicillin hemmt die bakterielle Zellwandsynthese durch Bindung an Penicillin-bindende Proteine (PBP) und blockiert die Quervernetzung der Peptidoglykan-Stränge.
