USE OF AT LEAST ONE DOLLAR G(A)62 CASEIN PEPTIDE WITH ANGIOTENSIN I CONVERTING ENZYME INHIBITING ACTIVITY FOR PREPARING MEDICINES, FOOD PRODUCTS AND FOOD COMPLEMENTS

摘要

The invention concerns the use for preparing anti-hypertensive medicines useful for treating or preventing hypertension, of one or more peptides having ACE inhibiting activity with IC50 values not more than 60 mu M, selected among peptide groups having the following amino acid sequences: Thr-Val-Tyr (SEQ ID NO: 1) Asn-Met-Ala-lle-Asn-Pro-Ser-Lys (SEQ ID NO: 2) Phe-Ala-Leu-Pro-Gln-Tyr (SEQ ID NO: 3) Phe-Pro-Gln-Tyr-Leu-Gln-Tyr (SEQ ID NO: 4) Phe-Ala-Leu-Pro-Gln-Tyr-Leu-Lys (SEQ ID NO: 5) Asn-Met-Ala-lle-Asn-Pro (SEQ ID NO: 6) Phe-Ala-Leu-Pro (SEQ ID NO: 7). The invention also concerns a pharmaceutical composition containing, as active principle, an efficient amount of one or more said peptides, in combination with a pharmaceutically acceptable carrier. The invention further concerns a food product, in particular for supplementing the diet of persons liable to hypertension or wishing to prevent its occurrence, containing an efficient amount of one or more said peptides, in combination with food supports, in particular proteins, lipids or carbohydrates. Such a food product may also include at least one of the peptides having the following amino acid sequences: Ala-Leu-Asn-Glu-lle-Asn-Gln-Phe-Tyr-Gln-Lys (SEQ ID NO: 8) Ala-Leu-Asn-Glu-lle-Asn-Gln-Phe-Tyr (SEQ ID NO: 9) Tyr-Leu (SEQ ID NO: 10).
