Chemical structure and biological activity relationship in bradykinin analogues containing proline-like unusual amino acids.
Ten different bradykinin analogues have been synthesized and tested for activity on isolated guinea-pig ileum. The results, in comparison with others in the literature, suggest some conclusions on a chemical structure - biological activity relationship.
