Synthesis and Evaluation of Fenofibric Acid Ester Derivatives: Studies of Different Formulation with Their Bioavailability and Absorption Conditions

Abstract

A series of fenofibric acid ester pro-drugs (JF-1-7) were synthesized. The pharmacokinetic properties of these pro-drugs were examined after oral administration to rats at a dose of 20 mg kg-1 to evaluate the relative bioavailability in rats. The bioavailability of the ester compounds, JF-1, 2, 3, 4, 5, 6, and 7, was significantly higher than that of fenofibrate. In particular, JF-2 proved to be most promising. The oral administration (20 mg kg-1) of JF-2 showed a relative bioavailability of approximately 272.8% compared to fenofibrate.
