esters were prepared through an enzymatic approach for the first time. The heterologousRhizopusoryzaelipase, immobilized on two different supports proved to be an efficientcatalyst, even more active than Candida antarctica lipase, in the esterification reaction using a complex substrate such as a bile acid. The immobilization of the enzyme on Octadecyl Sepabeads at pH 7 and 25 °C was the best choice

22.8 μM, respectively. In addition, in order to shed light to bileacids behavior in enzymatic reactions, molecular modeling was applied to some derivatives. The advantages showed by the enzymatic methodology, such as mild reaction conditions and low environmental impact, make the biocatalysis a convenient way to synthesize these bileacid derivatives with application as potential antiparasitic agents
