Achiral non-coded amino acids (N-benzylglycine, 2-aminomethylphenylacetic acid or 3-aminophenylacetic acid) were substituted at position 7 of the B-2 receptor antagonist [D-Arg(0), Hyp(3), Thi(5,8), D-Phe(7)]-BK. The N-terminal amino group of the analogues was either free or acylated with 1-Aca or Aaa. Biological activity of the compounds was assessed in the in vitro rat uterus test and the in vivo rat blood pressure test. Substitution in position 7 resulted in a decrease in antagonistic potency or change of the activity into agonistic one. Acylation of the N-terminus enhanced antagonistic properties of the resulting peptides in the rat blood pressure test.
