abstract = {The antihypertensive activity of two α-casein-derived peptides and casein hydrolysate containing these sequences was evaluated in the presence of naloxone. The activity was abolished by this opioid antagonist at 2, 4, and 6 h post-administration. Similarly, the antihypertensive effect of the α-casein peptides RYLGY (-23.8 ± 2.5 mmHg) and AYFYPEL (-21.1 ± 3.2 mmHg) at 5 mg/kg of body weight was antagonized by the co-administration of naloxone. Because peptide AYFYPEL had recently shown opioid activity, a molecular dynamic simulation of this peptide with human μ-opioid receptor was performed to demonstrate its favorable structure and interaction energy, despite the presence of Ala at the N terminus. Altogether, these results revealed that the effect on systolic blood pressure of the studied α-casein peptides is mediated by interaction with opioid receptors and the antihypertensive activity of casein hydrolysate can be very likely ascribed to them with the possible contribution of other mechanisms.},
