产品描述:
Tenofovir is an analog of adenosine monophosphate that has antiviral activity.{24520,24521} It is converted by cellular enzymes to tenofovir diphosphate, an obligate chain terminator that inhibits the activity of HIV reverse transcriptase and hepatitis B virus polymerase.{24519,24528} Tenofovir diphosphate is a weak inhibitor of mammalian DNA polymerases α and β and mitochondrial DNA polymerase γ.{24528} For in vivo and cell culture use, tenofovir is supplied as a water soluble prodrug in the form of tenofovir disoproxil (fumarate) (Item No. 16922), which increases the intracellular diphosphorylated compound >1,000-fold above the level attained with unmodified tenofovir.{24528}
