Tenofovir disoproxil fumarate is used to treat human immunodeficiency virus (HIV) and chronic type B viral hepatitis. Tenofovir disoproxil fumarate, an acyclic nucleoside phosphonate diester analog of adenosine monophosphate, is a prodrug that requires diester hydrolysis for conversion to tenofovir. Subsequent phosphorylation by cellular enzymes forms tenofovir diphosphate, an obligate chain terminator. Tenofovir diphosphate competes with the natural substrate deoxyadenosine 5’-triphosphate for incorporation into the viral DNA strand. After incorporation into viral DNA, tenofovir diphosphate inhibits the activity of HIV-1 reverse transcriptase and HBV polymerase by terminating the DNA chain. Tenofovir diphosphate is also a weak inhibitor of mammalian DNA polymerases α, β, and mitochondrial DNA polymerase γ.
