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. Synthroid: Levothyroxin ersetzt das defizitäre endogene Thyroxin, das in den Geweben durch Deiodinasen in das aktive Hormon Trijodthyronin (T3) umgewandelt wird.
