DNA polymerase抑制劑
傳統核苷類似物
Idoxuridine(IDU)
-
-
用途
只對DNA病毒有效(ex: herpes, vaccinia)
-
-
-
Ribavirin
-
-
機轉
-
IDU, TFT皆須變成三磷酸才有作用,Ribavirin只需變成RMP即可作用
-
開環核苷類似物
Acycloguanosine(Acyclovir,ACV)
-
-
-
-
-
Ganciclovir(cytorene, DHPG)
-
-
-
-
Cidofovir(HPMPC, Vistide)
-
-
Adefovir dipivoxil
-
為prodrug,經esterase水解成Adefovir,再磷酸化兩次形成Adefovir-DP P.S. 僅需磷酸化兩次:Cidofovir, Adefovir
