Penciclovir (PCV) and acyclovir are acyclic guanine analogs which inhibit herpes simplex virus (HSV) DNA polymerase. Their 50% infective doses were 0.5 to 0.8 microgram/ml for clinical isolates of HSV-1 and 1.3 to 2.2 micrograms/ml for HSV-2. Furthermore, HSV-infected cultures receiving 2-h pulses of PCV had 2- to 50-fold less HSV than acyclovir-treated cultures, consistent with the prolonged intracellular half-life of PCV triphosphate.
喷昔洛韦(PCV)和阿昔洛韦是无环鸟嘌呤类似物,可抑制单纯疱疹病毒(HSV)DNA聚合酶。对于HSV-1临床分离株,其50%感染剂量为0.5至0.8微克/毫升,对于HSV-2则为1.3至2.2微克/毫升。此外,接受2小时喷昔洛韦脉冲处理的HSV感染培养物中的HSV比接受阿昔洛韦处理的培养物少2至50倍,这与喷昔洛韦三磷酸酯延长的细胞内半衰期一致。
