Hippuryl-His-Leu-OH
Hippuryl-His-Leu-OH (N-Benzoyl-Gly-His-Leu) is a specific substrate for angiotensin-converting enzyme (ACE I) and a molecular tool used for ACE activity detection in in vitro experiments. Hippuryl-His-Leu-OH is hydrolyzed by ACE through competitive binding. Under ACE catalysis, Hippuryl-His-Leu-OH undergoes hydrolysis to produce hippuric acid (HA). The amount of HA produced can be used to quantitatively assess ACE activity or screen for ACE inhibitors. The released His-Leu can also react with o-phthalaldehyde or Fluorescamine (HY-D0715) for fluorescence detection. Hippuryl-His-Leu-OH can be applied to the in vitro screening of ACE inhibitors for hypertension and cardiovascular diseases, and is also used in the study of ACE activity changes in physiological and pathological processes such as renal compensatory hypertrophy.

Biological Activity
Hippuryl-His-Leu-OH (8.3 mM; incubated with the enzyme source for 15 minutes, then incubated with the substrate for 30 minutes) can be hydrolyzed by angiotensin-converting enzyme (ACE) to produce hippuric acid. The ACE inhibitory activity of substances such as Parkia biglobosa extract can be evaluated by detecting the amount of hippuric acid produced[1].
Hippuryl-His-Leu-OH (1 mM, 0.1 mM; incubated at 37°C for 150 min) as an ACE-specific substrate, its hydrolyzed product, hippuric acid, after solid-phase extraction (SPE) treatment, can be quantitatively detected by LC/SID-ESI-MS/MS technology, enabling efficient screening of ACE inhibitors in complex natural pigments and foods[2].
Hippuryl-His-Leu-OH is used as a substrate for spectrophotometric detection of ACE activity in serum and tissues. The generated hippuric acid has a characteristic absorption peak at 228 nm, which reflects the catalytic activity level of ACE[3].
