Angiotensin I-Converting Enzyme Inhibitor Derived from Cross-Linked Oyster Protein

Angiotensin I-Converting Enzyme Inhibitor Derived from Cross-Linked Oyster Protein

Following cross-linking by microbial transglutaminase, modified oyster proteins were hydrolyzed to improve inhibitory activity against angiotensin-converting enzyme (ACE) inhibitory activity with the use of a single protease, or a combination of six proteases. The oyster hydrolysate with the lowest 50% ACE inhibitory concentration (IC50) of 0.40 mg/mL was obtained by two-step hydrolysis of the ...

Milk protein-derived peptide inhibitors of angiotensin-I-converting enzyme.

Numerous casein and whey protein-derived angiotensin-I-converting enzyme (ACE) inhibitory peptides/hydrolysates have been identified. Clinical trials in hypertensive animals and humans show that these peptides/hydrolysates can bring about a significant reduction in hypertension. These peptides/hydrolysates may be classified as functional food ingredients and nutraceuticals due to their ability ...

Angiotensin-converting Enzyme Inhibitor

The hemodynamic effects of an oral angiotensin-converting enzyme inhibitor, captopril, were evaluated in 10 symptomatic patients with chronic congestive heart failure. In all patients there was a significant increase in cardiac output (average 28%), stroke volume (49%), and stroke work index (26%), along with a decrease in pulmonary capillary wedge pressure (48%), indicating improved left ventr...

Angiotensin-converting Enzyme Inhibitor

The effects of angiotensin-converting enzyme inhibitor (CEI) SQ14225 on infarct size and regional myocardial blood flow were studied in 21 anesthetized dogs subjected to 6 hours of coronary occlusion. An area of myocardium at risk of necrosis was determined in vivo after 15 minutes of coronary occlusion but before CEI treatment (AR1) using an autoradiographic technique and after treatment after...
