(EN) A novel benzenesulfonamide derivative of formula (I) which has an action of inhibiting phospholipase A2 and therefore is effective in treating diseases for which this action is used to advantage.(FR) Un nouveau dérivé de sulfonamide de benzène ayant la formule (I) a un effet inhibiteur de la phospholipase A2 et est par conséquent utile pour traiter des maladies lorsque cet effet inhibiteur est requis.
A novel series of 4-[N-methyl-N-[(E)-3-[4-(methylsulfonyl)phenyl]-2- propenoyl]amino]benzenesulfonamides has been prepared and evaluated as membrane-bound phospholipaseA2inhibitors. A structure-activity relationship study indicated that the optimum potency was realized with the N-(phenylalkyl)piperidine derivatives 3 and 4. These compounds inhibited the liberation of arachidonic acid from the rabbit
