Effect of Sodium Caseinate Hydrolysates on Angiotensin-I Converting Enzyme Inhibition Activity

Antioxidant activity and angiotensin I-converting enzyme inhibition by enzymatic hydrolysates from bee bread.

Enzymatic hydrolysates were prepared from bee bread using three proteases. The antioxidant properties of these hydrolysates were measured using four different methods. These had remarkable antioxidant activity similar or superior to that of 1 mM alpha-tocopherol. They also had high scavenging activities against active oxygen species as the superoxide anion radical and hydroxyl radicals. Moreove...

Effect of chronic angiotensin converting enzyme inhibition on angiotensin I and bradykinin metabolism in rats.

We determined the effect of chronic administration of the angiotensin converting enzyme (ACE) inhibitor, enalapril, on the in vivo pulmonary inactivation of bradykinin (BK) and conversion of angiotensin I (Ang I). In addition we assessed whether chronic ACE inhibition influenced the activity of prolylendopeptidase (PEP), which metabolizes Ang I to generate angiotensin-(1-7) (Ang-[1-7]) and inac...

Angiotensin Converting Enzyme in Sarcoidosis

Angiotensin I converting enzyme.

• Interest in particular biologically active substances waxes and wanes. Investigators rush into a newly opened field, solve a few problems, and frequently raise more; then they rush out to follow more promising developments elsewhere. However, interest in angiotensins generally has persisted and increased. Observation of the actions of angiotensins has led to the study of enzymes involved in t...

Effect of angiotensin-converting enzyme inhibition and angiotensin II receptor blockers on cardiac angiotensin-converting enzyme 2.

BACKGROUND Angiotensin-converting enzyme 2 (ACE2) has emerged as a novel regulator of cardiac function and arterial pressure by converting angiotensin II (Ang II) into the vasodilator and antitrophic heptapeptide, angiotensin-(1-7) [Ang-(1-7)]. As the only known human homolog of ACE, the demonstration that ACE2 is insensitive to blockade by ACE inhibitors prompted us to define the effect of ACE...
