Utibapril (FPL 63547) is an ester prodrug of a novel thiadiazoline ACE inhibitor. Utibapril was undergoing phase II clinical studies in the United Kingdom for the treatment of heart failure and hypertension. Utibapril is an angiotensin-converting enzyme (ACE) inhibitor with a proposed tissue-specific inhibitory profile. This implies that at a certain dose, utibapril should be able to inhibit tissue ACE activity without affecting plasma ACE.

Sample Use Guides

In Vivo Use Guide

Normal Wistar rats were randomly allocated to oral treatment with different doses of utibapril (0, 2, 10, 50, or 250 ug/kg/day) for 30 days. Utibapril significantly inhibited plasma, renal, and vascular ACE but not ventricular ACE activity. Notably, however, only treatment with the highest dose of utibapril resulted in a significant inhibition of plasma ACE, whereas vascular ACE activity was already significantly inhibited after treatment with a lower dose of utibapril.

Route of Administration: Oral

In Vitro Use Guide

Utibapril (FPL 63547), in its active diacid form, was a potent inhibitor of rabbit lung angiotension converting enzyme (ACE) in vitro (IC50 0.51 nM).
