Biochem/physiol Actions
Famciclovir is an antiretroviral guanosine analog used to treat herpesvirus infections and hepatitis B. Famciclovir is rapidly converted to penciclovir. Viral thymidine kinase phosphorylates penciclovir to a monophosphate form that celular kinases convert in turn to penciclovir triphosphate. Penciclovir triphosphate competitively inhibits viral DNA polymerase and thus viral replication. Prolonged administration can lead to resistance; it is often manifested as selection of pre-existing resistant strains with mutations in the reverse transcriptase domain of the DNA polymerase gene.

提醒大家几点：中检所和各地药检所售的都是药典或国家标准中应使用到的标准品和对照品，如果您是建立新药或某些新方法所用到的对照品，他们哪儿一般不会有，此时多为各研究单位自行制备对照品。
在您打电话询问时可以登入中检所的网站在搜索模块中下拉标准物质搜索，看看中检所是否已有此种物质。
若为地方升国标的标准中用到的对照品，中检所一般较少有，最好的方法是找到原始地方标准所在地，与该地的省所联系购买。
