New inhibitors of 5-lipoxygenase catalytic activity based on 2-(3-methylphenyl)propanoic acid and 4-substituted morpholine derivatives.

New potential inhibitors of 5-lipoxygenase (5-LOX) based on the structure of 2-(3-benzoylphenyl)propanoic acid (an active component of the nonsteroidal antiinflammatory drug Ketoprofen) were designed using the SARD-21 program. The docking of these compounds in the active site of 5-LOX suggested that seven compounds can interact with this enzyme. Two of them can also be dual inhibitors of 5-LOX and two isoforms of cyclooxygenase.
