Lactokinin
Lactokinin is an Endothelin-1 (HY-P0202) release inhibitor and ACE inhibitor, with an ACE IC50 value of 29 μM. Lactokinin binds to bovine β-lactoglobulin variant A to form a non-covalent complex, which delays its hydrolysis by chymotrypsin, as well as by pepsin/chymotrypsin, in vitro. Lactokinin can be used in research related to hypertension.

Biological Activity
Lactokinin is bound to purified bovine β-lactoglobulin variant A via non-covalent interactions, and the bound peptide is protected from oxidation and ion adduction during ionization compared to free lactokinin[1].
Lactokinin (0.1-1 mM) inhibits basal and thrombin-stimulated endothelin-1 release from cultured porcine aortic endothelial cells, with 1 mM reducing basal release by 29% and 0.1 mM and 1 mM reducing thrombin-stimulated release by 32% and 43%, respectively[2].
Lactokinin inhibits porcine kidney angiotensin-converting enzyme activity with an IC50 of 29 μM[2].
