Background:

H-Ile-Pro-Pro-OH (IPP) is a peptide inhibitor of angiotensin converting enzyme (ACE; IC50 = 5 μM).1 It inhibits acetylcholine-induced nitric oxide (NO) production in human umbilical vein endothelial cells (HUVECs) when used at a concentration of 1 μM and induces vasorelaxation in precontracted isolated rat aortic rings.2 IPP (0.3 mg/kg) decreases systolic blood pressure in spontaneously hypertensive, but not normotensive, rats.3 Dietary administration of IPP reduces plasma levels of total cholesterol, HDL-cholesterol, and triglycerides, mRNA expression of IL-6 and IL-1β, and aortic arch intimal thickening and atherosclerotic plaque formation in ApoE-/- mice.4
