Influence of discrete esters on the metabolism of tenofovir DF in homogenates from rat intestine; the concentration used was 1 mM for the esters and 1% v/v for the strawberry extract; values represent the percentage of inhibition of the enzymatic conversion of the prodrug to the mono(ester) after 5 min of incubation (mean ± S.D., n = 3)
