喷昔洛韦, Penciclovir

Penciclovir is an antiviral agent and acyclic guanine derivative. Penciclovir has proven efficient in the treatment of Herpes Simplex type 1 and 2 (HSV1 and HSV2) infection. Penciclovir is transformed by the virus into an active derivative able to block the deoxyguanosine triphosphate substrate binding site of the HSV polymerase.

Purine acyclic nucleoside analogue. Shows antiviral activity. Induces apoptosis without causing genotoxicity.

Penciclovir is a guanosine analog with antiviral activity. It has activity against multiple laboratory and clinical isolate strains of herpes simplex virus 1 (HSV-1), HSV-2, and varicella zoster virus (VZV) in a plaque reduction assay (IC50s = 0.4-3.1 μg/ml). Penciclovir inhibits HSV-1 and HSV-2 replication (IC99s = 0.4 and 0.7 μg/ml, respectively) and DNA synthesis (IC50 = 0.04 μg/ml) in MRC-5 cells. In vivo, topical and systemic administration of penciclovir reduces the severity of skin lesions caused by HSV-1 in guinea pigs and mice. It also prevents development of HSV-2-induced genital lesions in guinea pigs infected intravaginally.

Penciclovir, also known as BRL-39123, is a guanosine analogue antiviral drug used for the treatment of various herpesvirus infections. It is a nucleoside analogue which exhibits low toxicity and good selectivity. Because penciclovir is absorbed poorly when given orally it is used more as a topical treatment, and is the active ingredient in the cold sore medications Denavir, Vectavir and Fenivir.
