Wirkmechanismus

Targets/IC50/Ki
Estrogen receptor
In vitro

Estradiol induziert neue dendritische Dornen und Synapsen an hippokampalen CA1-Pyramidenzellen. Die Behandlung mit dieser Verbindung führte zu einer 46%igen Zunahme der NMDA-Rezeptorbindung. Es erhöht die NMDA-Rezeptorbindung parallel zur Dichte der dendritischen Dornen und Synapsen. Diese chemische Behandlung führt zu einer erhöhten Empfindlichkeit der CA1-Pyramidenzellen gegenüber NMDA-Rezeptor-vermittelten synaptischen Inputs, und diese Zunahme korreliert gut mit der Estradiol-induzierten Zunahme der dendritischen Dornendichte im apikalen dendritischen Baum dieser Zellen.

Es wurde festgestellt, dass diese Verbindung den Ba2+-Eintritt reversibel über Ca2+-Kanäle in akut dissoziierten und kultivierten neostriatalen Neuronen reduziert. 17 alpha-Estradiol reduziert ebenfalls Ba2+-Ströme, ist aber in Ratten-Neostriatal-Neuronen signifikant weniger wirksam als 17 beta-estradiol.

Es übt eine dosisabhängige Hemmung der IL-1-, TNF- und IL-1- und TNF-induzierten Produktion von bioassayfähigem IL-6 aus. Diese Chemikalie hemmt sowohl die TNF-induzierte IL-6-Produktion als auch die Osteoklastenentwicklung in primären Knochenzellkulturen, die aus neonatalen Maus-Calvarien gewonnen wurden.

In vivo

Estradiol vermittelt die Schwankungen der hippokampalen Synapsendichte während des Östruszyklus bei der erwachsenen Ratte.

Diese Verbindung allein kann den ovariektomiebedingten Rückgang der Dornendichte umkehren. In Kombination mit Progesteron erhöht sie zunächst die Dornendichte für einen Zeitraum von 2 bis 6 Stunden, führt dann aber zu einem viel stärkeren Rückgang, als dies nach der alleinigen Gabe dieser Chemikalie beobachtet wird.
