An enzymatic resolution process was developed to produce (S)-naproxen ester, (S)-naproxen or (S)-ibuprofen from the corresponding racemic thioesters by using lipase-catalyzedthiotransesterification or hydrolysis in organic solvents. Enzyme activity is greatly enhanced when activated naproxen thioesters containing an electron-withdrawing group are the substrates. Unlike other lipases, Candida rugosa

cSrc kinase inhibition assays were evaluated at a 10 μM concentration. The selected candidates displayed limited activities against the various tested kinases; the compounds 2a, 3b, 6a, 7a, 7b and 8a showed no activity to weak activity (% inhibition = ∼0-10%). The molecular docking study revealed the importance of the thioester moiety for the interaction of the drugs with the amino acids in the active
