Mechanism and action
Amoxil: Amoxicillin hemmt die bakterielle Zellwandsynthese durch Bindung an Penicillin-bindende Proteine (PBP) und blockiert die Quervernetzung der Peptidoglykan-Stränge. Acyclovir: Aciclovir ist ein Guanosin-Analogon, das durch die virale Thymidinkinase selektiv zur Monophosphat-Form und anschließend durch zelluläre Kinasen zu Aciclovir-Triphosphat phosphoryliert wird.
