[Effect of FOY-305 on the activity and secretion of pancreatic enzymes in vitro].
FOY-305, a synthetic inhibitor of serin-proteases, shows a highly specific inhibition of the activity of purified trypsin and tryptic activity from duodenal juice in a range of 1 to 10 microM. Phospholipase A2 is only partly inhibited (40%) by much higher concentrations of FOY-305 (100 microM to 1 mM), amylase activity is not affected by either concentrations. FOY-305 did not influence CCK-stimulated amylase- and trypsin-secretion from isolated pancreatic lobules in concentrations which inhibited completely tryptic activity.
