Mechanisms compared
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. Estriol: Estriol bindet an Östrogenrezeptoren, jedoch mit kürzerer Rezeptorbesetzung und schwächerer Aktivierung als Estradiol, was einen 'schwachen' östrogenen Effekt erzeugt.
