Ferreira isolated bradykinin-potentiating factors (BPFs) from the venom of the South American pit viper, *Bothrops jararaca*Activity of Various Fractions of Bradykinin Potentiating .... These factors were observed to enhance the pharmacological actions of bradykinin. Subsequent research led to the purification and characterization of individual bradykinin-potentiating peptides, revealing them to be short, proline-rich oligopeptidesBradykinin-potentiating and C-type natriuretic peptides. These peptides are not exclusive to snakes; they have also been identified in the venoms of spiders and in amphibian skin secretions, highlighting their diverse evolutionary presence.
The primary mechanism by which bradykinin-potentiating peptides exert their effect is through the inhibition of the angiotensin-converting enzyme (ACE). ACE is a key enzyme in the renin-angiotensin-aldosterone system (RAAS), responsible for converting angiotensin I into the potent vasoconstrictor angiotensin II. By inhibiting ACE, BPPs reduce the production of angiotensin II, thereby leading to vasodilation and a decrease in blood pressure.
Furthermore, BPPs also potentiate the activity of bradykinin itself. Bradykinin is a vasodilator that also increases vascular permeability and plays a role in pain and inflammation. By preventing the enzymatic breakdown of bradykinin, BPPs prolong its presence and activity in the body.Novel Bradykinin-Potentiating Peptides and Three-Finger ... This dual action—inhibiting ACE and potentiating bradykinin—contributes significantly to their hypotensive effects.Bradykinin-potentiating peptide 11
Over the years, numerous bradykinin-potentiating peptides have been identified and studied. Some notable examples include:
* BPP-10c: A well-characterized peptide from *Bothrops jararaca* venom, BPP-10c has been instrumental in studying the structure-activity relationships of BPPs and their ACE inhibitory potential.
* Bradykinin Potentiator B: Isolated from the venom of *Agkistrodon halys blomhoffi*, this peptide is also recognized as a potent ACE inhibitor.
* Bradykinin-Potentiating Peptide 5a: This peptide exhibits modest ACE inhibition, with a particular affinity for the N-site of the enzyme, and demonstrates strong bradykinin-potentiating activity作者：VV Babenko·2020·被引用次数：28—New toxins not found earlier in viper venom and including three-finger toxins andunusual bradykinin-potentiating peptideswere discovered..
* BPP-9a-F: Found in the venom of *Bothrops jararaca*, this peptide has shown variations in activity, with some forms present only in female snakes.
These peptides often exhibit modular structures, with variations in their amino acid sequences leading to differences in their potency, specificity for ACE inhibition, and bradykinin-potentiating capacityBradykinin potentiating peptide B.
