| Abstract: | Independently of their agonistic or antagonistic activity on different isolated tissue preparations, the kinin analogues investigated induce histamine release on rat peritoneal mast cells. The effectivity of most compounds is 10 to 100 times higher than that of bradykinin. Beside the positively charged amino acids, the elongation at the N-terminus with hydrophobic amino acids and the replacement of amino acids in the bradykinin sequence (especially at position 7) with aromatic residues is important for a high histamine-releasing activity. |
