A novel chymase inhibitor, 2-(5-formylamino-6-oxo-2-phenyl-1,6-dihydropyrimidine-1-yl)-N-[[,4-dioxo-1-phenyl-7-(2-pyridyloxy)]2-heptyl]acetamide (NK3201), suppressed intimal hyperplasia after balloon injury.

In this study, we investigated whether an orally active chymase inhibitor, 2-(5-formylamino-6-oxo-2-phenyl-1,6-dihydropyrimidine-1-yl)-N-[[3,4-dioxo-1-phenyl-7-(2-pyridyloxy)]-2-heptyl]acetamide (NK3201), prevents intimal hyperplasia in carotid arteries injured by a balloon catheter in dog. Each dog was administered NK3201 (1 mg/kg per day, p.o.) or placebo beginning 5 days before balloon injury and continuing through the experiments. Four weeks after balloon injury, NK3201 did not affect the plasma renin and angiotensin-converting enzyme activities. The chymase activity was significantly increased in the injured arteries, whereas the angiotensin-converting enzyme activity was not. NK3201 significantly reduced the chymase activity in the injured arteries. The intimal area in the placebo- and NK3201-treated group and was 0.46 +/- 0.06 and 0.24 +/- 0.04 mm2, respectively, and this difference was significant. In this study, we demonstrated for the first time that a chymase inhibitor prevented the development of intimal hyperplasia in the balloon-injured arteries.[1]
