title: Effect of methylcarbonylmethyl 2(S)-[4-(4-guanidinobenzoyloxy) phenyl] propionate methanesulfonate (TT-S24) on pancreatic secretion in rats.
abstract: The effect of methylcarbonylmethyl 2(S)-[4-(4-guanidinobenzoyloxy) phenyl] propionate methanesulfonate (TT-S24), a newly synthesized trypsin inhibitor, on exocrine pancreatic secretion was examined and compared with that of camostat in rats. Intraduodenal (i.d.) administration of TT-S24 and camostat resulted in an increase in volume, amylase concentration and amylase output of pancreatic juice. Although i.v. injection of TT-S24 and camostat (3 mg/kg) had no effect on the pancreatic juice volume, TT-S24 (i.v.) dose-dependently increased pancreatic juice volume under acetylcholine (10 micrograms/kg/min) infusion. In addition, the weight of pancreases from WBN rats was significantly increased by 28 day oral administration of TT-S24 (100 mg/kg) with a potency similar to that observed with camostat.
