Mechanisms compared
Estrace: Estradiol bindet an Östrogenrezeptoren (ERα und ERβ) in Zielgeweben und moduliert die Genexpression für vaskuläre, ossäre, reproduktive, zentralnervöse und metabolische Funktionen. 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.
