Glucophage: Metformin senkt die hepatische Glukoseproduktion durch Hemmung des mitochondrialen Komplexes I, wodurch das zelluläre AMP/ATP-Verhältnis steigt und die AMP-aktivierte Proteinkinase aktiviert wird. Doxycycline: Doxycyclin bindet reversibel an die 30S-Untereinheit bakterieller Ribosomen, verhindert die Bindung von Aminoacyl-tRNA und hemmt damit die Proteinsynthese.
