title: Recent chymase inhibitors and their effects in in vivo models.
abstract: Recent efforts to discover novel chymase inhibitors have produced orally bioavailable compounds. Studies using such inhibitors have shed light on the pathophysiological roles of chymase, eg, a chymase inhibitor has prevented atherosclerosis, restenosis and myocardial infarction in respective animal models. In these cardiovascular diseases, angiotensin I is likely involved as a substrate for chymase. The studies using chymase inhibitors have also shown the potential role of chymase in other diseases, including atopic dermatitis, tissue fibrosis and rheumatoid arthritis; a chymase inhibitor also reduced ischemic reperfusion injury in the small intestine. These results suggest the existence of physiological substrates for chymase other than angiotensin I. Chymase inhibitors are promising for the treatment of cardiovascular as well as inflammatory diseases.
