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. Levothyroxine: Levothyroxin ersetzt das fehlende endogene Thyroxin, das in den Geweben durch Deiodinasen in das aktive Hormon Triiodthyronin (T3) umgewandelt wird.
