vitro studies, in the presence of added esterase, and 19F NMR studies, in biological media, indicated that the E-enol acetate derivatives should act as prodrugs in vivo. The ED50 value for (E)-N-[4-(4-morpholinylcarbonyl)benzoyl]-L-valyl-N-[2- (acetyloxy)-3,3,4,4,4-pentafluoro-1-(1-methylethyl)-1-buteny l]-L-prolinamide (20), when administered orally in the hamster lung hemorrhage model, was 9 mg/kg
