IC50: 0.27μM (ACE)[1]
In Vitro Intravenous injection of Leucylarginylproline (30mg/kg) causes a decrease in the blood pressure. The maximum mean blood pressure reduction (about 15 mmHg) occurrs about 2 min after the injection[1]. Leucylarginylproline peptide reduces the blood pressure by about 15 mmHg at the fourth hour and shows a maximal reduction effect of about 35 mmHg at the eighth hour after oral administration[2].
Kinase Assay Hip-His-Leu (5mM) and an ACE inhibitor (Leucylarginylproline) are dissolved in a 100 mM sodium borate buffer (pH 8.3) containing 300 mM NaCl, and incubated for 30 min with 8 milliunits of ACE at 37°C. The ACE inhibitor concentration required to inhibit 50% of the ACE activity under the above conditions is defined as IC50[1].
Animal Admin Rats: Leucylarginylproline is dissolved in 1.0 mM normal saline. After being warmed up, rats are orally administered (0.18 mmol/kg bw) with peptides or normal saline (control). Tail systolic blood pressures are measured at 2-h intervals (0, 2, 4, 6, 8, 10, and 12 h) after the administration[2].
