Abstract:
:Perfluorination of phthalimides leads to dramatically increased potency as inhibitors of TNF-alpha production. We examined the enantiodependence for several tetrafluorophthalimides and alpha-methylthalidomide, 3. Only 3 exhibited strikingly enantiodependent activity. The key structural determinant for the enhanced activity is the tetrafluorophthaloyl group, which confers enhanced potency and a change in the mechanism of inhibition.
