Antiviral drug
|
应用领域
|
Used for the treatment of various herpes virus infections, most commonly for herpes zoster (shingles).
|
生物活性机理
|
Guanine analogue
|
生物活性机理
|
Prodrug of penciclovir with improved oral bioavailability
|
生物活性机理
|
Undergoes rapid biotransformation to penciclovir
|
生物活性机理
|
In cells infected with HSV-1, HSV-2 or VZV, viral thymidine kinase phosphorylates penciclovir to a monophosphate form
|
生物活性机理
|
that, in turn, is converted to penciclovir triphosphate by cellular (human) kinases
|
生物活性机理
|
Penciclovir triphosphate selectively inhibits viral DNA polymerase by competing with deoxyguanosine triphosphate
|
生物活性机理
|
Consequently, herpes viral DNA synthesis and replication are selectively inhibited.
