Mechanism and action
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. Diflucan: Fluconazol ist ein Triazol-Antimykotikum, das das Cytochrom-P450-abhängige Enzym Lanosterol-14-alpha-Demethylase hemmt und dadurch die Synthese von Ergosterol aus Lanosterol blockiert.
