Bradykinin-potentiating peptide both inhibits the activity of the angiotensin-converting enzyme (ACE) and enhances the action of bradykinin by inhibiting the peptidases that inactivate it. It acts as an indirect hypotensive agent (By similarity). Neither synthetic Tf1, nor synthetic Tf2 show bradykinin-potentiating effects. Has a vasorelaxant activity in rat aortic strips and a diuretic potency in anesthetized rats. Has a vasorelaxant activity in rat aortic strips and a diuretic potency in anesthetized rats. Is as potent as Tf-CNP. Expressed by the venom gland. In the N-terminal section; belongs to the bradykinin-potentiating peptide family. In the C-terminal section; belongs to the natriuretic peptide family.
