Angiotensin I-converting enzyme inhibitory activity and antioxidant capacity of bioactive peptides derived from enzymatic hydrolysis of buffalo milk proteins

, 2017
Buffaloes' milk, which is consumed in many parts of the world, is a little-explored source of bioactive peptides. The angiotensin converting enzyme (ACE)-inhibitory activity and the antioxidant capacity of peptides from buffaloes' milk were examined.

Identification of peptides in Qingke baijiu and evaluation of its angiotensin converting enzyme (ACE) inhibitory activity and stability.

Food Chemistry, 2022
The active peptides in Qingke baijiu fermented from Qingke (highland barley) are rarely reported. This work was designed to accurately identify peptides in Qingke baijiu and evaluate their angiotensin-converting enzyme inhibitory activities in vitro ...

Inhibitory Effects of Plant Phenols on the Activity of Selected Enzymes

Journal of Agricultural and Food Chemistry, 2002
Selected enzymes (alpha-amylase, trypsin, and lysozyme) were allowed to react with some simple phenolic and related compounds (caffeic acid, chlorogenic acid, ferulic acid, gallic acid, m-, o-, and p-dihydroxybenzenes, quinic acid, and p-benzoquinone). The derivatized enzymes obtained were characterized in terms of their activity.

New biscoumarin derivatives-cytotoxicity and enzyme inhibitory activities

Bioorganic & Medicinal Chemistry, 2006
Biscoumarin derivatives 1-27 were tested for their inhibition of snake venom and human nucleotide pyrophosphatase phosphodiesterase-1 enzymes. Lineweaver-Burk and Dixon plots and their secondary replots showed that these compounds are pure non-competitive inhibitors of both the enzymes.

Inhibitory activity of flavonols towards the xanthine oxidase enzyme

International Journal of Pharmaceutics, 1992
Abstract The spectrophotometric methods of analysis adopted for the study of the inhibition of the enzyme, xanthine oxidase, are very different as regards the time required for the assay. With a view to studying the inhibitory effect of flavonoids, we examined the stability and the inhibitory activity of quercetin and myricetin in relation to ...

Synthesis and Enzyme Inhibitory Activities of Novel Peptide Isosteres

Current Medicinal Chemistry, 2002
Design and synthesis of metabolically stable peptide analogs that can either mimic or block the bioactivity of natural peptides or enzymes is an important constituent of bioorganic and medicinal chemistry research. Isosteric replacement of a scissile peptide bond represents a viable and popular approach in the rational design of peptidomimetics ...

Angiotensin-I Converting Enzyme Inhibitory Activity of Coffee Melanoidins

Journal of Agricultural and Food Chemistry, 2007
Melanoidins formed at the last stage of the Maillard reaction have been pointed out to possess certain functional properties. Potential antihypertensive activity of food melanoidins (coffee, beer, and sweet-wine) has been evaluated according to in-vitro ACE-inhibitory activity.
