Tenofovir
Tenofovir is an acyclic nucleotide diester analog of adenosine monophosphate. In the most strict sense and due to the fact that it presents a phosphate group bound to the nitrogenous base, it is determined as an actual nucleotide analog. The antiviral activities of tenofovir were first reported in 1993 and this agent was commercially available since 2008 in the form of [tenofovir disoproxil] and [tenofovir alafenamide] in order to obtain oral bioavailability.
