An irreversible resolution of ketoprofen prodrug was developed by lipase-catalysed hydrolysis using corresponding vinyl ester as activated substrate in organic medium. The product obtained, (S)-ketoprofen vinyl ester would be used as a potential prodrug and a significant monomer for polymeric drug. Lipozyme®immobilized fromMucor mieheishowed the highest selectivity and activity after enzyme screening. The effect of solvent, water amount in the reaction medium and reaction temperature on the activity and enantioselectivity of Lipozyme®was studied. Polymerizable, optically active ketoprofen prodrug could be obtained with excellent enantioselectivity (ee >99%,E~ 400) in a mixture of dioxane/water (97.5/2.5, v/v) at 25 °C.
