Mechanisms compared
Doxycycline: Doxycyclin bindet reversibel an die 30S-Untereinheit bakterieller Ribosomen, verhindert die Bindung von Aminoacyl-tRNA und hemmt damit die Proteinsynthese. Fluconazole: Fluconazol ist ein Triazol-Antimykotikum, das das Cytochrom-P450-abhängige Enzym Lanosterol-14-alpha-Demethylase hemmt und so die Biosynthese von Ergosterol aus Lanosterol blockiert.
